containers / python-podman

Python bindings and code examples for using Varlink access to Podman Service

podman - pythonic library for working with varlink interface to Podman

Status: Deprecated

See podman-py

Overview

Python podman library.

Provide a stable API to call into.

Notice: The varlink interface to Podman is currently deprecated and in maintenance mode. Podman version 2.0 was released in June 2020, including a fully supported REST API that replaces the varlink interface. The varlink interface is being removed from Podman at the 3.0 release. Python support for the 2.0 REST API is in the python-py repository. The documentation for the REST API resides here.

Releases

Requirements

• Python 3.5+
  • See How to install Python 3 on Red Hat Enterprise Linux if your installed version of Python is too old.
• OpenSSH 6.7+
• Python dependencies in requirements.txt

Install

From pypi

Install python-podman to the standard location for third-party Python modules:

python3 -m pip install podman

To use this method on Unix/Linux system you need to have permission to write to the standard third-party module directory.

Else, you can install the latest version of python-podman published on pypi to the Python user install directory for your platform. Typically ~/.local/. (See the Python documentation for site.USER_BASE for full details.) You can install like this by using the --user option:

python3 -m pip install --user podman

This method can be useful in many situations, for example, on a Unix system you might not have permission to write to the standard third-party module directory. Or you might wish to try out a module before making it a standard part of your local Python installation. This is especially true when upgrading a distribution already present: you want to make sure your existing base of scripts still works with the new version before actually upgrading.

For further reading about how python installation works you can read this documentation.

By building from source

To build the podman egg and install as user:

cd ~/python-podman
python3 setup.py clean -a && python3 setup.py sdist bdist
python3 setup.py install --user

Code snippets/examples:

Show images in storage

import podman

with podman.Client() as client:
  list(map(print, client.images.list()))

Show containers created since midnight

from datetime import datetime, time, timezone

import podman

midnight = datetime.combine(datetime.today(), time.min, tzinfo=timezone.utc)

with podman.Client() as client:
    for c in client.containers.list():
        created_at = podman.datetime_parse(c.createdat)

        if created_at > midnight:
            print('Container {}: image: {} created at: {}'.format(
                c.id[:12], c.image[:32], podman.datetime_format(created_at)))

python-podman's Issues

Container Exec

The ExecContainer varlink method is not available in the API.

No option to publish ports on pod

Looking at the varlink schema, there's an option to set the published ports when creating a pod.

https://github.com/containers/libpod/blob/9758a975e67bb9d681d351aea0d858ace598dcdf/cmd/podman/varlink/io.podman.varlink#L451-L460

This library doesn't seem to expose that.

pypodman export: ">" does NOT work

Is this a BUG REPORT or FEATURE REQUEST?:

kind bug

Description
">" has the same functionality as -o/--output option to export container to a tar archive. podman can do it successfully, but pypodman not.

Steps to reproduce the issue:
On Remote:
podman varlink socket is started, and there's already a container existing:

[root@rhel8-1 ~]# podman ps -a
CONTAINER ID   IMAGE                             COMMAND     CREATED          STATUS                      PORTS   NAMES         IS INFRA
79dde10d5d87   docker.io/library/fedora:latest   /bin/bash   21 minutes ago   Exited (0) 21 minutes ago           test-export   false

On Host:

1. ~/.local/bin/pypodman -l root --host 192.168.122.213 export > fedora-ctn.tar test-export

Describe the results you received:

[root@localhost libpod]# ~/.local/bin/pypodman -l root --host 192.168.122.213 export > fedora-ctn.tar test-export
2018-11-27 16:32:28 CST | ERROR    | pypodman export: the following arguments are required: --output/-o
2018-11-27 16:32:28 CST | ERROR    | Try 'pypodman export --help' for more information.

Describe the results you expected:
On remote, podman export > fedora-ctn.tar test-export can export the container test-export properly.

[feature] allow lambda to run with podman instead of docker

• allows you to containers not as root
• cgroups v2
• better support on centos8/fedora OSs

should be an alternative, and not a replacement, as docker is more widespread than podman

pypodman search: output should add a column to show the `index` as podman does

Is this a BUG REPORT or FEATURE REQUEST?:

kind feature

Description
INDEX column is important information to let users know where the images come from. podman search has this column, but pypodman does not. And NAME column should have the registry location part.

Steps to reproduce the issue:
On remote

[root@rhel8-1 ~]# podman search --filter is-official=True alpine
INDEX       NAME                       DESCRIPTION                                       STARS   OFFICIAL   AUTOMATED
docker.io   docker.io/library/alpine   A minimal Docker image based on Alpine Linux...   4803    [OK]

Describe the results you received:
On host:

root@localhost libpod]# pypodman -l root --host 192.168.122.213 search --filter is-official=True alpine
NAME                                         DESCRIPTION                                  STARS OFFICIAL AUTOMATED
alpine                                       A minimal Docker image based on Alpine Linux 4803  [OK]

Describe the results you expected:
On the host, pypodman searchshould have the INDEX column as well, and NAME column should include the registry location.

containers.list() gathers too much data

---

I'm facing an issue with the simplest possible API call that I could think about

with podman.Client() as client:
...: list(client.containers.list())

which on my setup, with one single container running, takes in the 2 minutes

---

This issue was first opened in the plain podman repo
containers/podman#4656

in that issue we have established that this mundane API call actually gathers information about disk space, which in this particular instance I do not need at all, but that slows things down terribly; the fact that 2 minutes are needed here is clearly a concern too, but should be taken separately

---

bottom line, I would like to know if there is currently a way to quickly obtain a simple list of containers, with minimal - even if quite incomplete - attached information;

README.MD should have note about V2 changes

A note should be added to the top of the README to note the changes upcoming in V2 Podman.

Trigger automated checks to keep python-podman aligned with libpod defined interfaces

Summarize

In the sake of compatibilty in libpod and python-podman I propose to design and implement automated checks to verify if python-podman implementation is fully compatible with libpod varlink defined interface.

The goal of this ticket is to discuss about this feature design and watch how we could implement this and the needs behind this (impact on project workflow, how to proceed etc...).

Draft design

Project lifecycle

I think we need to create a git branch dedicated for each libpod version that we want to maintain to avoid to introduce future features into wrong branches and python-podman releases, in other word we need to isolate development versions.

The master branch will only reflect the libpod master and will help us to synchronize changes between future latest versions only.

I think we need as many version of python-podman than existing libpod versions to keep the python-api compatible with libpod defined interface.

Triggering automated checks

The automated check can be trigger from:

• the libpod side when changes are pushed on https://github.com/containers/libpod/blob/master/cmd/podman/varlink/io.podman.varlink
• the python-podman side daily by triggering cronjob on each opened branches

The automated check need to reflect the relation between version on the both projects, we only need to compare the varlink defined interface in the right libpod tag version and on the right development branch version on python-podman.

If we choose to trigger automated checks on python-podman then we need to pull from the right libpod tag/branch the raw varlink defined interface file (by using http request) and then compare it the python-podman implementation.

How to compare interface with implementation

For the moment I see some solutions to compare if these projects are synchronized, lets describe them.

Maybe you will see other/better solutions to manage this.

Don't forget that the main goal of this issue is to discuss with you if we can do this and how to do this before starting to spend time on it. Also I want to raise pro and con that I may miss.

First solution

The main idea in this solution is to compare function signatures.

Steps needed in order:

• download the raw interface description form libpod repo
• parse the previous download file to extract defined signature
• parse the function implementation available in python-podman
• compare the both and observe if delta exists
• raise error if delta exist
• automatically open a new github python-podman issue with attached job output to inform us and then fix the issue

The main difficulty here is how to ignore perifical function which are part of the python-podman mechanisms and not related to interface implementation... Since python-podman is only compatible with python3 we could by example use the powerful python inspect module coupled with a standardized mechanism which will allow us to analyze keywords in functions's docstrings to detect if the function is part of the interface definition, determine which interface the implementation is linked and if signature need to be compared with interface definition.

All these things can be done in pure python without extra module and dependencies (or just to some mainstream requirements).

We don't need to compile and install libpod here, we just need to refer to the related interface.

I think this one is the more preferable solution and the more safer and the less painful.

Second solution

On travis's instance compile and install the right libpod version and then start its varlink server, and then run unit tests against but I think it's more likely that libpod's varlink defined interface will be ahead of the python-podman implementation. In this case it can be difficult to witness raised exceptions from the python-podman side because the python-podman would not pass undefined params (except if some params are removed from libpod and not yet removed from python-podman).

Maybe I'm wrong by thinking this way, I'm not sure if all params are mandatory and if exceptions can be raised by doing this. If exception are raised then it's can be a way to identify non synchonized interface implemention in python-podman.

My main concern about this solution is how to properly manage travis instance, libpod rights (sudo etc...), rootless needs, etc... on a travis's instance image which could have some limitations. I think it can be painful to follow this way and our goal is not to test libpod but just to observe if implementation is rightly synchronized, I don't want to fight with windmills here.

Third solution

By adding new capabilities to the varlink's mocking feature it will allow us to generate a fake service by lookup form the downloaded raw interface to generate some fake python classes (rather than generating fake interface definition from fake python class as is currently the case).

Then we can mix solution 1 and solution 2 approachs (if enough unit test exists for solution 2), and by example compare generated function's signatures and real implementation signatures.

Like has explained in the second solution I'm not sure if 100 percent of the args are mandatories and if some are missing I'm not sure we will catch exception and error. Anyway with this approach libpod stay ahead of the python-podman implementation so this is the main risk.

This is a cross project solution which ask to us to adding new feature on the varlink side and in a second time to implement the check on python-podman.

The main advantage here is to provide feature which can be reused outside of the scope podman (the feature added to varlink).

Conclusion

I think we need this kind of feature to avoid to spend time fix issue unsynchronized implementation.

Also I think these changes can help us to better handle the support of libpod's versions on python-podman and to more often and more merely release new versions of this API.

Do not hesitate to react to my proposal by sending comments here.

Pull image function throws KeyError for id

Pull image function pull(self, source)for Python podman throws following error as the function tries to returns id from results

Traceback (most recent call last):

KeyError: 'id'

Is there an API documentation?

after looking at the code's docstrings, i understand that there is unsufficent embedded documentation to build an API documentation.

Maybe you want to keep this issue open for others that are wondering how they could employ this library until API docs are available.

pypodman kill: option "-a/--all" and "-l/--latest" are not implemented

Is this a BUG REPORT or FEATURE REQUEST?:

kind feature

Description
As the title said, these two options are not implemented, but podman can use them smoothly.
podman kill doc:

--all, -a
Signal all running containers. This does not include paused containers.
--latest, -l
Instead of providing the container name or ID, use the last created container. If you use methods other than Podman to run containers such as CRI-O, the last started container could be from either of those methods.

Although these two options are not provided as parameters in varlink method:

method KillContainer(name: string, signal: int) -> (container: string)

but we might implement this with the help of the other methods besides KillContainer().

podman package can be used on windows smoothly.

Document minimum system requirements

Think you need to list minimum versions required, of the various system tools used:

• Python 3.5+ (?)

• OpenSSH 6.7+

Had some issues, when I tried to use older versions:

    **options,
             ^
SyntaxError: invalid syntax

https://docs.python.org/3/whatsnew/3.5.html#whatsnew-pep-448

PEP 448 extends the allowed uses of the * iterable unpacking operator and ** dictionary unpacking operator. It is now possible to use an arbitrary number of unpackings in function calls:

Bad local forwarding specification '/tmp/pypodman/podman.socket:/run/podman/io.podman'

https://www.openssh.com/txt/release-6.7

• ssh(1), sshd(8): Add support for Unix domain socket forwarding.
  A remote TCP port may be forwarded to a local Unix domain socket
  and vice versa or both ends may be a Unix domain socket.

Shouldn't be unreasonable to demand (?), but would be good to document anyway...

pypodman search: a ValueError is raised when nothing can be searched out

Is this a BUG REPORT or FEATURE REQUEST?:

pypodman commit: option "--message" still does not work

Is this a BUG REPORT or FEATURE REQUEST?:

kind bug

Description
After #1881, option --message still doesn't work. Probably because the option --format is not implemented and --message can be set only when --format has value docker, which can refer to https://github.com/containers/libpod/blob/master/docs/podman-commit.1.md:

--message, -m
Set commit message for committed image. The message field is not supported in oci format.

The argument --format/-f is not gotten from argparser, and --message should only be able to set when --format is docker:
https://github.com/jwhonce/libpod/blob/f8c5e75a10fb0a9a3a3c113075c129521c5c5099/contrib/python/podman/podman/libs/containers.py#L133-L137

Steps to reproduce the issue:
On Remote:

[root@rhel8-1 ~]# podman ps -a
CONTAINER ID   IMAGE                             COMMAND     CREATED       STATUS                   PORTS   NAMES         IS INFRA
5460b2b46177   docker.io/library/fedora:latest   /bin/bash   2 hours ago   Exited (0) 2 hours ago           test-commit   false

On Host:

1. ~/.local/bin/pypodman -l root --host 192.168.122.213 commit --message "test commit msg" test-commit image-commited
2. ~/.local/bin/pypodman -l root --host 192.168.122.213 commit --message "test commit msg" --format docker test-commit image-commited1

Describe the results you received:

1. The image image-commited is created, but it has no comment message:

[root@rhel8-1 ~]# podman inspect image-commited
[
    {
        ......
        "Comment": "",
        ......
   }
]

2. The image image-commited1 is created, but it still has the type oci(by default) and doesn't have the comment message too:

[root@rhel8-1 ~]# podman inspect image-commited1
[
    {
       ......
        "Comment": "", 
       ......
       "ManifestType": "application/vnd.oci.image.manifest.v1+json",
       ......
    }
]

Describe the results you expected:

1. the command should fail.
   If I do this on remote with podman:

[root@rhel8-1 ~]# podman commit --message "test commit msg" test-commit image-commited
messages are only compatible with the docker image format (-f docker)

2. If I do the same thing on remote with podman commit --message "test commit msg" --format docker test-commit image-commited2:

[root@rhel8-1 ~]# podman inspect image-commited2
[
    {
        ......
        "Comment": "test commit msg",
        ......
       "ManifestType": "application/vnd.docker.distribution.manifest.v2+json",
        ......
    }
]

Push Image function throws KeyError: 'image'

Observation :

Fully specify dependencies

I realise a lot is in flux here with and after #25, but just mentioning that I tried to install from git, and the installation process does not trigger any dependencies to be pulled in (I'm sure that once published to PyPI this would work already a bit better), and the metadata seems to be missing some packages.

First error I got was missing package varlink, and while installing that, I got:

>pip install varlink
Collecting varlink
  Downloading https://files.pythonhosted.org/packages/80/4f/8ac1e3fd7f766b68a5273926faf810d7a2d81863ce0a57c74b47461dd353/varlink-30.1.2-py2.py3-none-any.whl
ERROR: podman 0.0.1 requires psutil, which is not installed.
ERROR: podman 0.0.1 requires python-dateutil, which is not installed

So it seems psutil / python-dateutil are specified, but not varlink, and neither the missing package error I got after installing all that.

>>> import podman
Traceback (most recent call last):

[...]
>pip install fcntl
Collecting fcntl
  ERROR: Could not find a version that satisfies the requirement fcntl (from versions: none)
ERROR: No matching distribution found for fcntl

Not sure what else might be missing, since I cannot install fcntl from either pip or conda.

pypodman: 'attach' doesn't

I think pypodman/lib/actions/attach_action.py got created as a skeleton but never actually implemented. I'm sorry, rewriting it is currently more than I can dive into right now.

Can anyone please tell me whether my usage of the functionality is wrong.

Call host podman inside a container but encounter `Connection refused` error

I want to call host podman inside a container by podman python client

So I do

1. run a contianer and mount podman socket
   podman run -it --privileged --entrypoint=bash -v /lib/systemd/system/io.podman.socket:/lib/systemd/system/io.podman.socket docker.io/python:3.6

2. then I login to the container, install python package
   python3 -m pip install podman

3. call podman with the socket unix:/lib/systemd/system/io.podman.socket like what I did with docker but error shows

pypodman logs: option `--since`, `-f` and `-t/--timestamps` are not implemented

Is this a BUG REPORT or FEATURE REQUEST?:

kind feature

Description
As the title, below options are not implemented:

--follow, -f
Follow log output. Default is false
--since=TIMESTAMP
Show logs since TIMESTAMP. The --since option can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the client machine's time. Supported formats for date formatted time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05, 2006-01-02T15:04:05.999999999, 2006-01-02Z07:00, and 2006-01-02.
--timestamps, -t
Show timestamps in the log outputs. The default is false

The implementation of --follow might be difficult/impossible, but --since and --timestamps are possible.

Multiple Volumes not reported

When inspecting an Image, only one volume is reported.

From podman inspect:

            "Volumes": {
                "/mc/banned-ips.json": {},
                "/mc/banned-players.json": {},

            }

From Image.inspect():

pypodman restart: option '--all' and '--running' do NOT work

Libary calls do not work

I installed podman and the python podman library. But I does not show any images or containers:

    for image in client.images.list():
        print(image)
    print(client.containers.list())
    for container in client.containers.list():
        print(container)

Output:

<generator object Images.list at 0x7f41cbd344c0>
<generator object Containers.list at 0x7f41cbd344c0>

Am I doing anything wrong? I installed it first following this blog post. Does this break anything due to the new API. Also is there a documentation anywhere?

Publish sdist tarballs on pypi

Currently only wheels are published on pypi (see https://pypi.org/project/podman/#files ).
But distros might want to build from an sdist tarball so please publish that in addition to the current .whl file.

release date for new podman 1.6.1 pypi ? - with the exec method included in the libs/containers.py module

Ping method was removed from podman

No pypodman command seem to work anymore:
CRITICAL | 'SimpleClientInterfaceHandler' object has no attribute 'Ping'

Probably because that method was removed:

"endpoint requires a more connection"

When attempting to build an image, I get this extremely nonsensical error:

>>> podcraft.poddir.build_server(pm, "/home/astraluma/.mc/qwi", {})

The invocation is

client.images.build(
    buildArgs=buildargs,  # Dictionary, empty
    contextDir=buildroot,  # String, full path to a .tar
    dockerfile=dockerfile,  # String, full path to Dockerfile
    tags="TODO",
    annotations={
        'podcraft.root': serverdir,  # String, a full path (doesn't exit)
    },
)

Best as I can read the go code (don't know go) and can google, this sounds like the particulars of how python-podman is constructing the varlink invocation?

Images.build incorrectly uses os.walk

The method podman/libs/images.py#Images.build runs os.walk, and expects it to return a list of files from context_directory. It actually yields a 3-tuple (dirpath, dirnames, filenames) as described here. Later, when trying to add files into the tar archive (line 176), the program fails with error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/edd/.local/lib/python3.8/site-packages/podman/libs/images.py", line 189, in build
    tar.addfile(tar.gettarinfo(fileobj=open(name)))
TypeError: expected str, bytes or os.PathLike object, not tuple

While we're at it, how is this code expected to function when encountering an empty directory?

[Help] Can't start created container: executable file not found in $PATH

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

I can get the container to start just fine if I use the CLI:

podman run jupyterhub/singleuser:latest

is succesful.

I tried using a different image, and it works fine:

# up log level
import logging
logging.getLogger().setLevel(logging.DEBUG)
# action
import podman
with podman.Client() as client:
    image_id = client.images.pull("alpine:latest")
    image = client.images.get(image_id)
    container = image.create()
    container.start()

I then tried doing a mix: creating the container with the CLI:

podman container create jupyterhub/singleuser:latest

which returns a container id <container-id>, and then using the Python API to start it:

# up log level
import logging
logging.getLogger().setLevel(logging.DEBUG)
# action
import podman
with podman.Client() as client:
    container = client.containers.get(<container-id>)
    container.start()

which is successful

Additionally, I can go the other way: create the container with the Python API

# up log level
import logging
logging.getLogger().setLevel(logging.DEBUG)
# action
import podman
with podman.Client() as client:
    image_id = client.images.pull("jupyterhub/singleuser:latest")
    image = client.images.get(image_id)
    container = image.create()
    print(container.id)

which outputs <container-id>, and I can use the CLI to start it:

podman container start <container-id>

which gives an error:

Error: unable to start container "a07d93be42c8c13e39b4185c1fb16c9677b3f99da1c15c15728348085998d604": container_linux.go:349: starting container process caused "exec: \"tini\": executable file not found in $PATH": OCI runtime command not found error

This tells me that there's something going wrong with how this particular image is being created as a container using the Python API.

Here's the inspect information for the image:

$ podman --version
podman version 2.0.6

$ python -m pip freeze | grep podman
podman==1.6.1.dev50
$ python -m pip freeze | grep varlink
varlink==30.3.0

I was previously running podman version 1.6.4, from the default Centos repositories, paired with the default python-podman version from the PyPi repository, but I was experiencing the same behavior before and after both upgrades.

I've read elsewhere that this might have to do with the container's file system not mounting correctly? Perhaps there is also something simple I am missing in how to use the Python API. Any help is appreciated!

history() doesn't work

import podman

pclient = podman.Client()

img = pclient.images.get('6c0fc7ee13e0')

for his in img.history():
print(his)

fails with :
Traceback (most recent call last):
File "test.py", line 11, in
for his in img.history():
TypeError: 'list' object is not callable

problem is that when Image object is created, it defines attribute history and sets it to '[]'

which overrides history() method

Is there a way to pass variables like "tls-verify=false" when pushing images?

pypodman: publish to pypi

kind feature

Description

The python library, pypodman, is not published to PyPI. This makes it harder for folks to write python code that depends on it.

pypodman inspect: option "--format" is not implemented

Is this a BUG REPORT or FEATURE REQUEST?:

kind feature

Description
It seems that option --format is not implemented yet for pypodman: https://github.com/jwhonce/libpod/blob/842320d2f7922c2ea66f57a07d0a5f67d980de48/contrib/python/pypodman/pypodman/lib/actions/inspect_action.py#L17-L35
For keeping consistency with podman, pypodman should implement option --format as well.

clarify LICENSE situation

Currently there are two license files (LICENSE & LICENSE.txt) which seem redundant. Podman itself just uses one LICENSE file.

This should IMO be deduplicated.

[Questions] related to the varlink server address format

Hello,

Do you seen any reasons (that I maybe missed) to limit the client uri to a local path (i.e unix:/run/podman/io.podman)?

If I'm right varlink also accept tcp addresses (i.e tcp://127.0.0.1:38005) and in this case podman specifically ignore them.

• Do you you have any reasons to ignore this kind of address (tcp format)?
• Do you think that we could adapt this code to allow users to pass tcp format too?

To allow you to better understand our needs and why I ask these questions lets me explains a little bit our situation. I implemented a podman client in tobiko (a new testing framework for openstack) and tobiko establish an SSH connection to the openstack node (controller, compute, etc) and then it proxifying server connections through tcp to allow us to centralize SSH config and mechanismes in only one place.

For these reasons we prefer to pass through a proxified python-podman LocalClient and ssh/tcp rather than using a python-podman RemoteClient and a direct usage of SSH with python-podman.

Example with the code bellow:

from tobiko.shell import ssh
from tobiko.tripleo import overcloud

ssh_client = overcloud.overcloud_ssh_client('controller-0')
uri = 'unix:/run/podman/io.podman'
print(ssh.get_port_forward_url(ssh_client=ssh_client, url=uri))
# will print 'tcp://127.0.0.1:38005'

The previous code opened a SSH connection on the controller-0 of the openstack tripleo's overcloud and then we proxify the varlink connection through tcp by calling ssh.get_port_forward_url which will return the proxified podman's varlink server address and so, now, we would like to use it with a python-podman LocalClient and we facing the previous described python-podman's limitation.

I hope these infos help you to understand our use case.

For further reading you can also take a look to https://review.opendev.org/#/c/700527/

If you need more info do not hesitate to ask questions I will be happy to help you.

Newest version is "lower" than highest version on PyPi

PyPI has a release 0.12.0, wherease the newest tag is 0.0.3; see also https://github.com/containers/python-podman/releases

This causes pip install podman to install 0.12.0 over the newer 0.0.3.

AFAIK (here's a ref), it's not possible to retract a package from PyPI, so the only choice would be to start releasing 0.13 and upwards.

Missing package version

Now that the package is no longer under the libpod repository, should it be versioned independently?

If so, one should have in mind that the last release on pypi was 0.11.1.1 (it would also be nice to Tag this repository in the revision that originated the pypi release).

This issue may also be related to #25

How to use push args using SDK

I successfully used the push args through cmd but found that there are no options for the args using the push function.

@rhatdan Is there a way/example to use the push options through podman SDK?

Can not create a new container from an image

With python3.7 and podman installed from git in a virtualenv:

# cat reproducer.py

with podman.Client() as client:

    image = client.images.get(image_id)
    image.create(command=['/usr/bin/top'])

I get:
