Red Hat OpenShift Container Platform Cheat Sheet

Red Hat OpenShift Container Platform Cheat Sheet

Let's list out our current available projects (those that we have at least view access for):

$ oc get projects


If this is our rst login and no one has added us to any existing projects, there shouldn't be any projects listed. Let's create a project (allowed by self-provisioner role to all authenticated users, in the default Openshift policy installation).

$ oc new-project myproject --display-name='My Project' --description='cool project owned by myuser'


Now using project "myproject" on server "". To build a new example applicatin on Ruby you can add applications to this project with the 'new-app' command. For example, try:

oc new-app centos/ruby-22-centos7~
See a step-by-step example to build, deploy and manage an application with OpenShift and look at administrator tasks that can impact developers.

  1. docker CLI
    1. Container Related Commands
      docker [CMD] [OPTS] [CONTAINER]

      All examples shown work in Red Hat Enterprise Linux
      1. Run a container in interactive mode:
        #Run a bash shell inside an image
        $ docker run -it rhel7/rhel bash
        #Check the release inside a container
        [root@.../]# cat /etc/redhat-release

      2. Run a container in detached mode:
        $ docker run --name mywild y -d -p 8080:8080 jboss/wild y
      3. Run a detached container in a previously created container network:
         $ docker network create mynetwork
        $ docker run --name mywild y-net -d --net mynetwork
         -p 8080:8080 jboss/wild y

      4. Run a detached container mounting a local folder inside the container:
         $ docker run --name mywild y-volume -d
        -v myfolder/:/opt/jboss/wild y/standalone/deployments/
        -p 8080:8080 jboss/wild yjboss/wild y

      5. Follow the logs of a specific container:
         $ docker logs -f mywild y
        $ docker logs -f [container-name|container-id]
Get started with an introduction to container architecture including engine, image, registry, volume, related commands.
