Because kubectl is great, but sometimes a bit slow to navigate.
Enter KubeFuse.
Beta quality software for quick Kubernetes browsing and editing. What's not to love.
- Browse Kubernetes resources in your file system...
- ...with (some of) your favourite tools:
ls
,find
,cat
,vim
, ... - List all your favourite resources such as: services, replication controllers, pods and namespaces. All entity types up to v1.3 are supported.
- Access resource descriptions as files (eg.
cat ~/kubernetes/default/pod/postgres-aazm1/describe
) - Quickly read resources as YAML or JSON (eg.
cat ~/kubernetes/default/pod/postgres-aazm1/json
) - Edit resources with your editor of choice and have Kubernetes update on writes (
vim ~/kubernetes/default/rc/postgres/json
๐) - Works with Python 2 and 3
A more detailed introductory post can be found on this beautiful blog.
KubeFuse runs on both Linux and Mac, but does require additional libraries to be installed (eg. OSXFUSE).
KubeFuse also uses the kubectl binary under the hood so this needs to be on the path.
You should be able to:
pip install kubefuse
After which the kubefuse command will be installed into a bin/
directory that
is hopefully already on your path (if not look for the line starting with
Installing kubefuse script to ....
and add that directory to your PATH and
restart your shell).
You should then be able to run:
kubefuse [MOUNTPOINT]
When "building" from source:
pip install -r requirements.txt
Will install all the dependencies (on fresh systems you may need to
easy_install pip
first). After which you can run KubeFuse with:
python kubefuse/kubefuse.py [MOUNTPOINT]
KubeFuse is extensively tested using a tool called
Myna. It also uses the nose
framework
to discover and orchestrate the tests. To run the tests install Myna and then:
make test
Create the mount:
python kubefuse.py ~/kubernetes
List all pods in the default namespace:
ls ~/kubernetes/default/pod/
List all known objects in the default namespace:
find ~/kubernetes/default -type d -mindepth 2
Describe the postgres
pod:
cat ~/kubernetes/default/pod/postgres-aazm1/describe
Get logs from a graphite
pod:
cat ~/kubernetes/default/pod/graphite-i3bb2/logs
Export the postgres
replication controller to YAML:
cat ~/kubernetes/default/rc/postgres/yaml
Export the postgres
replication controller to JSON:
cat ~/kubernetes/default/rc/postgres/json
Export all service definitions in the default namespace:
find ~/kubernetes/default/svc -name yaml | while read line ; do cat $line ; echo "----" ; echo ; done
We can edit replication controllers and other resources in our editor. Saving the file will replace the resource in kubernetes:
vim ~/kubernetes/default/rc/postgres/json
