Table: Installing container platform

Platform	Description
Docker on Ubuntu	Supported version: Docker 18.09 and later For detailed instructions on installing the Docker on Ubuntu, see Install Docker Engine on Ubuntu.
Docker on RHEL 7.x	Supported version: Docker 1.13.x and later Use the following process to install Docker on RHEL. Enable your subscriptions: # sudo subscription-manager register --auto-attach --username=<username> --password=<password> # subscription-manager repos --enable=rhel-7-server-extras-rpms # subscription-manager repos --enable=rhel-7-server-optional-rpms Install Docker using the following command: # sudo yum -y install docker Reload the system manager configuration using the following command: # sudo systemctl daemon-reload Enable and then restart the docker service using the following commands: # sudo systemctl enable docker # sudo systemctl restart docker If SELinux is enabled, change the mode to permissive mode. Edit the `/etc/selinux/config` configuration file and modify the `SELINUX` parameter value to `SELINUX=permissive`. Restart the system for the changes to take effect. Verify that the SELinux mode change is in effect using the following command: # sudo sestatus The `Current Mode` parameter value in the command output should appear as `permissive`. For detailed instructions on installing Docker on RHEL, see Getting Docker in RHEL 7. If the docker is using default storage driver (overlay2 or overlay) on XFS backed file system, then ensure that XFS FS has ftype option set to 1. Use xfs_info to verify. For details, see Use the OverlayFS storage driver. Otherwise, you can use different storage driver. For details, see Docker storage drivers.
Podman on RHEL 9, 8.6 and 8.4	Supported version: Podman 4.0.2 and later Notes: Enable your subscriptions: # sudo subscription-manager register --auto-attach --username=<username> --password=<password> If SELinux is enabled, change the mode to permissive mode. Edit the `/etc/selinux/config` configuration file and modify the `SELINUX` parameter value to `SELINUX=permissive`. Restart the system for the changes to take effect. Verify that the SELinux mode change is in effect using the following command: # getenforce The `Current Mode` parameter value in the command output should appear as `permissive`. Ensure that the following services are enabled and running: # systemctl enable podman-restart # systemctl start podman-restart # systemctl enable podman.socket # systemctl start podman.socket
