Running a container using Podman and UBI

Now that you have the container tools from the Application Stream repository installed, let’s run a simple container based on Red Hat UBI that contains a set of official container images and extra software based on RHEL. To run a UBI image, it only takes a single command, as illustrated in the following code snippet:

[root@rhel-instance ~]# podman run –it registry.access.redhat.com/ubi9/ubi bash
Trying to pull registry.access.redhat.com/ubi9:latest...
Getting image source signatures
Checking if image destination supports signatures

Copying blob c6e5292cfd5f done
Copying config 168c58a383 done
Writing manifest to image destination
Storing signatures
[root@e38453f5e055 /]#

Check the hostname; it has changed from rhel-instance to e38453f5e055, which means we are inside the container.

Tip

These tutorials run commands as root, but one of the benefits of Podman is that it can run containers...
