Verifying that your tools are using Podman

When you have configured your host to use Podman rather then Docker, consider verifying your setup works as intended.

Prerequisites

• Docker service is stopped, or not installed.
• Saved containers are imported to Podman
• The DOCKER_HOST environment variable is set
• On macOS, the podman-mac-helper service is running
• Podman is emulating Docker CLI

Procedure

1. The Docker socket replies successfully for listing all containers:

   Windows

   $ curl --unix-socket npipe:////./pipe/docker_engine "http:/v1.41/containers/json?all=true"

   macOS

   $ curl --unix-socket /var/run/docker.sock "http:/v1.41/containers/json?all=true"

   Linux

   $ curl --unix-socket /var/run/docker.sock "http:/v1.41/containers/json?all=true"

2. Podman commands run successfully when redirected to the Docker socket:

   Windows

   $ CONTAINER_HOST=npipe:////./pipe/docker_engine podman ps

   macOS

   $ CONTAINER_HOST=/var/run/docker.sock podman ps

   Linux

   $ CONTAINER_HOST=/var/run/docker.sock podman ps
