Podman

Create and run a Vagrant box with Podman

1. Create a Vagrantfile with the following code:

   Vagrant.configure("2") do |config|
     config.vm.box = "fedora/32-cloud-base"
   
     config.vm.provider "virtualbox" do |vb|
       vb.memory = "1024"
     end
   
     config.vm.provision "shell", inline: "yum install -y podman"
   
     config.vm.network "forwarded_port", guest: 2979, host: 12979, auto_correct: true
   
   end

   This Vagrantfile provisions a virtual machine with Fedora and runs it in VirtualBox (Vagrant will download the Fedora box if it is not available). It also installs Podman on the machine and forwards host port 12979 to guest port 2979 on the box. We will use port 12979 to connect to the Podman API from PyCharm on the host machine.

2. Run the Vagrant box from the directory where you created the Vagrantfile:

   $
   vagrant up

Start the Podman API service

1. After the Vagrant box with Fedora starts up, SSH into it:

   $
   vagrant ssh

2. Run the following command inside the virtual machine:

   [vagrant@localhost ~] $
   podman system service --time=0 tcp:0.0.0.0:2979

   This command will create a listening service that will answer Podman API calls on port number 2979 inside the Vagrant box. This is where port number 12979 is forwarded from the host machine. The session will not expire unless you terminate it manually. If you want to open the service for a limited period of time, change the value of --time to specify the timeout in seconds.

Connect to Podman from PyCharm

1. Press Ctrl+Alt+S to open the IDE settings and select Build, Execution, Deployment | Docker.

2. Click to add a Docker configuration.

3. Select TCP socket and specify the Podman API service URL in Engine API URL: tcp://localhost:12979.

   

   If everything is correct, you should see Connection successful at the bottom of the page.

4. Double-click the configured Podman connection in the Services tool window (View | Tool Windows | Services or Alt+8).

PyCharm will make calls to this URL as if to the Docker Engine API, Vagrant will forward them to port 2979 inside the virtual machine with Podman, and the Podman API service will answer these calls.
