Using Podman

Podman is a free and open source alternative to Docker. Install the Podman Machine.

tip

Even though Podman has a GUI manager, quitting from the manager doesn't always release all of the memory resources. To make sure that the Podman Machine has shut down, run:

podman machine stop

tip

When using Podman, simply replace docker with podman in all TrustGraph commands.

caution

Resource allocation requirements, especially memory may be different when using Podman. In general, increase the memory allocation for any service that appears to be misbehaving. While it may be necessary to increase the container memory resources, the Podman Machine will likely consume less host system memory than the Docker Engine.
