we want to install docker packages on our RHEL 8.4 server (this is off line installation since machine not connected to network)

so we download the following rpm’s from the site – https://download.docker.com/linux/centos/8/x86_64/stable/Packages/

-rw-r--r-- 1 root root 34558068 Sep  6 14:41 containerd.io-1.6.9-3.1.el8.x86_64.rpm
-rw-r--r-- 1 root root  3930488 Sep  6 14:42 docker-scan-plugin-0.9.0-3.el8.x86_64.rpm
-rw-r--r-- 1 root root 13710120 Sep  6 14:42 docker-buildx-plugin-0.11.2-1.el8.x86_64.rpm
-rw-r--r-- 1 root root 25375804 Sep  6 14:42 docker-ce-24.0.6-1.el8.x86_64.rpm
-rw-r--r-- 1 root root  7514336 Sep  6 14:43 docker-ce-cli-24.0.6-1.el8.x86_64.rpm
-rw-r--r-- 1 root root  5119608 Sep  6 14:43 docker-ce-rootless-extras-24.0.6-1.el8.x86_64.rpm
-rw-r--r-- 1 root root  7370924 Sep  6 14:43 docker-compose-plugin-2.6.0-3.el8.x86_64.rpm

then we tried to install the rpm’s with yum localinstall but we get the following exception

Error:
 Problem: package containerd.io-1.6.9-3.1.el8.x86_64 conflicts with runc provided by runc-1.0.0-70.rc92.module+el8.4.0+10607+f4da7515.x86_64
  - package containerd.io-1.6.9-3.1.el8.x86_64 obsoletes runc provided by runc-1.0.0-70.rc92.module+el8.4.0+10607+f4da7515.x86_64
  - package buildah-1.19.7-1.module+el8.4.0+10607+f4da7515.x86_64 requires runc >= 1.0.0-26, but none of the providers can be installed
  - conflicting requests
  - problem with installed package buildah-1.19.7-1.module+el8.4.0+10607+f4da7515.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

one of exception above is complain about – requires runc >= 1.0.0-26

but when we check the runc rpm version we get:

rpm -qa | grep runc
runc-1.0.0-70.rc92.module+el8.4.0+10607+f4da7515.x86_64

so I not understand why yum complained about version runc-1.0.0-70 and other exceptions

any suggestion to solve this problem? and what is the right approach to install the rpm on rhel 8?

  1. You have this problem because you have installed runc which provide the functionality to run containers. Just use podman to run containers.

    Or deinstall podman, runc and then install docker.

  2. Docker has detailed steps for installing on RHEL/CentOS that it looks like you’ve skipped: https://docs.docker.com/engine/install/centos/

    It looks like you have multiple competing installations of the tools and you need to pick one. I don’t believe installing buildah/podman in addition to docker will be supported.
