Official in this context is limited to packages. yum would ignore the additional architecture, but users might get confused.Īs of RHEL 8 Red Hat does not package or support docker, they switched to a different container tools set including podman. Likely the RHEL repo containing only s390x is because that architecture does not exist for CentOS. As a user, doesn't really matter as long as it has been tested to work with RHEL. Like every other CentOS user, they will need to decide to build on Stream or RHEL or something else. Presumably Docker will continue to provide EL rpms after the end of the year. It is RHEL, but with earlier exposure to changes before they are generally available. CentOS Stream flips this around to be testing the next RHEL updates. Install Portainer on CentOS 8 / RHEL 8 for Docker Management. Docker has been installed successfully and running fine, now we will install and configure portainer so that we can manage docker from web interface. Prior to 8, CentOS Linux released after the same RHEL version. To verify that docker ce engine has been setup correctly, run below docker command, docker run hello-world.
Although yes Docker should figure out what to do about Stream. You need to use sudo to run Docker commands.Using the centos repo from should work on RHEL and rebuilds including CentOS. After installing the packages, start the Podman systemd socket-activated service using the following command: sudo systemctl start podman.socket. The docker group is created but no users are added to it. Other than Podman and its dependencies, be sure the podman-docker and docker-compose packages are installed. In this tutorial, we saw how it is possible to install Docker CE on Rhel8, by using the official Docker repository for CentOS7, which is a 100 compatible clone. You should now be ready to start using Docker and creating container images.ĭocker Engine is installed and running. Sudo docker run hello-world Running Docker and creating containers Then re run the command to verify Docker is running
If you receive a message ‘ Cannot connect to the Docker daemon‘, means that you will need to start the Docker service. When the container runs, it prints an informational message and exits as per the following screenshot: This command downloads a test image and runs it in a container. To verify that Docker Engine is working correctly, type the following command
