Podman Container Manager
|
|
=========================
|
|
|
|
Podman is a tool to manage pods and containers. Pods come from Kubernetes, that
|
|
define a pod this way:
|
|
|
|
A Pod (as in a pod of whales or pea pod) is a group of one or more
|
|
containers, with shared storage and network resources, and a specification
|
|
for how to run the containers.
|
|
|
|
.. important::
|
|
|
|
CoreOS doesn't mandate the use of `podman` for running container.
|
|
|
|
But as we can't support every existing container runtime, `podman` is the
|
|
only documented/supported way to run container.
|
|
|
|
Other container runtimes are available inside the open source
|
|
`meta-virtualization` layer that is available inside CoreOS.
|
|
|
|
Podman can be installed on an image by adding `podman` to the
|
|
:ref:`IMAGE_FEATURES <ref-features-image>` variable.
|
|
|
|
By default, this will just provide the `podman` command. The `podman` command
|
|
is similar to the `docker` one, and most command should work by replacing
|
|
`docker` by `podman`. See https://docs.podman.io/en/latest/Commands.html for
|
|
more info.
