Podman Virtual Machine Operations

Podman Virtual Machine Initialization

https://docs.podman.io/en/latest/markdown/podman-machine-init.1.html#

Podman on MacOS requires a virtual machine. This is because containers must run with a Linux kernel, and the Podman virtual machine provides that kernel.

podman machine init

initializes a new Linux VM where the containers are run.

For more details, see

Podman Virtual Machine

Start Virtual Machine

https://docs.podman.io/en/latest/markdown/podman-machine-start.1.html

Once the VM is initialized, it must be stared with:

podman machine start

Install System Helper

The system helper service is not installed; the default Docker API socket address can't be used by podman. If you would like to install it run the following commands:

sudo /opt/brew/Cellar/podman/4.2.1/bin/podman-mac-helper install
podman machine stop; podman machine start

This solved this issue:

podman build -f common/docker/Dockerfile [...]
Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM  
Error: unable to connect to Podman. failed to create sshClient: connection to bastion host (ssh://core@localhost:61201/run/user/501/podman/podman.sock) failed: dial tcp [::1]:61201: connect: connection refused

You can still connect Docker API clients by setting DOCKER_HOST using the following command in your terminal session:

export DOCKER_HOST='unix:///Users/ovidiu/.local/share/containers/podman/machine/podman-machine-default/podman.sock'

Stop Virtual Machine
