Chapter 33. Red Hat Enterprise Linux Atomic Host 7.3.3

MicroDNF

The microdnf package (microdnf-2-2.el7.1.1) contains a limited functionality package manager written in C. This minimal subscription-manager plugin implementation for microdnf does not enable any repositories by default. As a consequence, all repositories managed by subscription-manager are disabled in container. To enable the necessary repositories, use the --enablerepo option. For example:

    microdnf install --enablerepo rhel-7-server-rpms httpd

    microdnf install --enablerepo rhel-7-server-rpms httpd

This way, you can install packages from repositories managed by subscription-manager by enabling them manually.

The microdnf package is added to the rhel-atomic minimal base image to replace the yum facility. It has a limited number of features from the dnf command that only allow you to enable or disable repositories, install and remove packages, and clean out cache. Run microdnf --help from inside of the rhel-atomic container to see all available options.
