Docker Container Management from Cockpit

Cockpit can manage containers via docker. This functionality is present in the Cockpit docker package. Cockpit communicates with docker via its API via the /var/run/docker.sock unix socket. The docker API is root equivalent, and on a properly configured system, only root can access the docker API. If the currently logged in user is not root then Cockpit will try to escalate the user’s privileges via Polkit or sudo before connecting to the socket. Alternatively, we can create a docker Unix group. Anyone in that docker group can then access the docker API, and gain root privileges on the system. [root@rhel8 ~] #  yum install cockpit-docker    -y  Once the package installed then "containers" section would be added in the dashboard and we can manage the containers and images from the console. We can search or pull an image from docker hub just by searching with the keyword like nginx centos.   Once the Image download...

Add The Group Information IN Yum Repository in simple Two steps

= Yum groups and repositories = Yum supports the group commands   * grouplist   * groupinfo   * groupinstall   * groupremove   * groupupdate Groups are read from the "group" xml metadata that is optionally available from each repository. If yum has no repositories which support groups then none of  the group operations will work.  #yum grouplist    This will list the installed and available groups for your system in two    separate lists. If you pass the optional 'hidden' argument then all of     the groups which are set to 'no' in the group xml tag.   yum groupinfo groupname     This will give you detailed information for each group including:   description, mandatory, default and optional packages.       #yum groupinstall groupname      #yum groupupdate groupname   Despite their differing names both of these commands perform the same   func...
