OpenShift Dedicated provides methods for communicating from outside the cluster with services running in the cluster. This method uses an Ingress Controller.

Creating a project and service

If the project and service that you want to expose do not exist, first create the project, then the service.

If the project and service already exist, skip to the procedure on exposing the service to create a route.

  • Install the oc CLI and log in as a cluster administrator.

  1. Create a new project for your service:

    $ oc new-project <project_name>

    For example:

    $ oc new-project myproject
  2. Use the oc new-app command to create a service. For example:

    $ oc new-app \
        -e MYSQL_USER=admin \
        -e MYSQL_PASSWORD=redhat \
        -e MYSQL_DATABASE=mysqldb \
  3. Run the following command to see that the new service is created:

    $ oc get svc -n myproject
    Example output
    NAME             TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)    AGE
    mysql-80-rhel7   ClusterIP   <none>        3306/TCP   4m55s

    By default, the new service does not have an external IP address.

Exposing the service by creating a route

You can expose the service as a route by using the oc expose command.


To expose the service:

  1. Log in to OpenShift Dedicated.

  2. Log in to the project where the service you want to expose is located:

    $ oc project project1
  3. Run the following command to expose the route:

    $ oc expose service <service_name>

    For example:

    $ oc expose service mysql-80-rhel7
    Example output
    route "mysql-80-rhel7" exposed
  4. Use a tool, such as cURL, to make sure you can reach the service using the cluster IP address for the service:

    $ curl <pod_ip>:<port>

    For example:

    $ curl

    The examples in this section use a MySQL service, which requires a client application. If you get a string of characters with the Got packets out of order message, you are connected to the service.

    If you have a MySQL client, log in with the standard CLI command:

    $ mysql -h -u admin -p
    Example output
    Enter password:
    Welcome to the MariaDB monitor.  Commands end with ; or \g.
    MySQL [(none)]>
