$ oc new-project <project_name>
OpenShift Dedicated provides methods for communicating from outside the cluster with services running in the cluster. This method uses an Ingress Controller.
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.
Create a new project for your service:
$ oc new-project <project_name>
For example:
$ oc new-project myproject
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 \
registry.redhat.io/rhscl/mysql-80-rhel7
Run the following command to see that the new service is created:
$ oc get svc -n myproject
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
mysql-80-rhel7 ClusterIP 172.30.63.31 <none> 3306/TCP 4m55s
By default, the new service does not have an external IP address.
You can expose the service as a route by using the oc expose
command.
To expose the service:
Log in to OpenShift Dedicated.
Log in to the project where the service you want to expose is located:
$ oc project project1
Run the following command to expose the route:
$ oc expose service <service_name>
For example:
$ oc expose service mysql-80-rhel7
route "mysql-80-rhel7" exposed
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 172.30.131.89:3306
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 172.30.131.89 -u admin -p
Enter password:
