thelonelyghost / packer-podman

Packer template for creating a podman "remote" server, using Virtualbox and Vagrant

Podman Remote

Given the lack of equivalent to Docker Desktop for Podman, and that MacOS is a popular developer workstation, this shim has appeared.

Requirements

• Packer >= v1.6.0
• Vagrant
• VirtualBox
• Podman
• (optional) timeout from GNU coreutils

Usage

It is fair to use thelonelyghost/podman-remote from https://app.vagrantup.com/ since every tagged version there correlates exactly to a tag in the git repo.

There are 2 main scripts for setting up a VM and connecting your local podman client to it: setup-from-dist.sh and setup-from-source.sh. Each one is very similar to the other, but the main exception is setup-from-source.sh uses the local vagrant box that is output from running packer build . instead of the one uploaded to Vagrant Cloud.

A suggested, idempotent workflow might leverage ./setup-from-dist.sh to look like this:

~/workspace $ ./setup-from-dist.sh
[a lot of output]

If Vagrant Cloud doesn't seem trustworthy, one can build it on their own with Packer, then start the VM and configure it to work with podman. Everything you need for that build is either contained in this repository or available publicly:

~/workspace $ packer build .
[a lot of output]

~/workspace $ ./setup-from-source.sh
[a lot more output]
