The latest release of the RHEL 8 / CentOS 8. Red Hat has built its own tools, buildah and podman, which aim to be compatible with existing docker images and work without relying on a daemon, allowing the creation of containers as normal users, without the need of special permissions (with some limitations: e.g. at the moment of writing, it's still not possible to map host ports to the container without privileges).

Some specific tools, however, are still missing: an equivalent of docker-compose, for example does not exists yet. In this tutorial we will see how to install and run the original Docker CE on Rhel8 by using the official Docker repository for CentOS7.

In this tutorial you will learn:
  • How to enable the docker-ce repository on RHEL 8 / CentOS 8
  • How to install docker and docker-compose on RHEL 8 / CentOS 8
docker-RHEL 8 / CentOS 8
Docker installed on RHEL 8 / CentOS 8

There may come a time when that package you want to install in RHEL 8 / CentOS 8 is simply not available as a RPM file. The alternative is to download the source and compile it yourself, or - alternatively - generate a RPM file from that source code later on.

But there is another way. Given the fact that Debian-based distributions have way more users than RPM-based ones, the number of available packages in their repositories is greater. Chances are you will be able to find a DEB file for that package you want. Here is how to install that DEB file in RedHat Linux with the help of a small utility called alien.

In this tutorial you will learn:
  • How to install alien in RHEL 8 / CentOS 8
