7.4. Adding software in a standard UBI container

Procedure

1. Pull and run the registry.access.redhat.com/ubi10/ubi image:

   $ podman run -it --name myubi registry.access.redhat.com/ubi10/ubi

2. Add a package to the myubi container.

   • To add a package that is in the UBI repository, disable all dnf repositories except for UBI repositories. For example, to add the bzip2 package:

     # dnf install --disablerepo= --enablerepo=ubi-10-for-x86_64-appstream-rpms --enablerepo=ubi-10-for-x86_64-baseos-rpms bzip2*

   • To add a package that is not in the UBI repository, do not disable any repositories. For example, to add the zsh package:

     # dnf install zsh

   • To add a package that is in a different host repository, explicitly enable the repository you need. For example, to install the python38-devel package from the codeready-builder-for-rhel-8-x86_64-rpms repository:

     # dnf install --enablerepo=codeready-builder-for-rhel-10-x86_64-rpms python3-devel

Verification

1. List all enabled repositories inside the container:

   # dnf repolist

2. Ensure that the required repositories are listed.

3. List all installed packages:

   # rpm -qa

4. Ensure that the required packages are listed.
