This machine is currently configured in rootless mode. If your containers
require root permissions (e.g. ports < 1024), or if you run into compatibility
issues with non-podman clients, you can switch using the following command:

 podman machine set --rootful

API forwarding listening on: /Users/lambda.eranga/.local/share/containers/podman/machine/podman-machine-default/podman.sock

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/homebrew/Cellar/podman/4.4.2/bin/podman-mac-helper install
 podman machine stop; podman machine start

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

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

Machine "podman-machine-default" started successfully
podman machine start

# we need to have rootful podman
❯❯ podman machine set --rootful

# now podman machine is running
❯❯ podman machine ls
