How to find public IP address of MySQL persistent on Openshift 3 web console?

Question

I deployed Wildfly application and MySQL persistent on Openshift web console and tried to connect MySQL persistent with jdbc driver of Eclipse outside. However I can not find the public IP address at all on web console.

How can I find public IP address of MySQL persistent or how to configure the specific IP address into MySQL persistent? I attach an image of both services on Openshift.

On Eclipse IDE, I opened the log part of MySQL pod. And I found the IP addresses of MySQL service:

"readinessProbe" : {
                "exec" : {"command" : [
                    "/bin/sh",
                    "-i",
                    "-c",
                    "MYSQL_PWD=\"$MYSQL_PASSWORD\" mysql -h 127.0.0.1 -u $MYSQL_USER -D $MYSQL_DATABASE -e 'SELECT 1'"
                ]},
                "initialDelaySeconds" : 5,
                "timeoutSeconds" : 1,
                "periodSeconds" : 10,
                "successThreshold" : 1,
                "failureThreshold" : 3
            },

....

"phase" : "Running",
        "conditions" : [
            {
                "type" : "Initialized",
                "status" : "True",
                "lastTransitionTime" : "2017-04-02T06:35:00Z"
            },
            {
                "type" : "Ready",
                "status" : "True",
                "lastTransitionTime" : "2017-04-03T16:47:27Z"
            },
            {
                "type" : "PodScheduled",
                "status" : "True",
                "lastTransitionTime" : "2017-04-02T06:35:00Z"
            }
        ],
        "hostIP" : "172.31.14.159",
        "podIP" : "10.1.72.72",
        "startTime" : "2017-04-02T06:35:00Z",
        "containerStatuses" : [{
            "name" : "mysql",
            "state" : {"running" : {"startedAt" : "2017-04-03T16:47:07Z"}},
            "lastState" : {"terminated" : {
                "exitCode" : 255,
                "reason" : "Error",
                    "startedAt" : "2017-04-02T06:36:28Z",
....

I tried to connect MySQL pod with the hostIP, 172.31.14.159 or podIP, 10.1.72.72. But connection failed. And then I found the following MySQL generation commands in the log contents:

"exec" : {"command" : [
                        "/bin/sh",
                        "-i",
                        "-c",
                        "MYSQL_PWD=\"$MYSQL_PASSWORD\" mysql -h 127.0.0.1 -u $MYSQL_USER -D $MYSQL_DATABASE -e 'SELECT 1'"
                    ]},

So, I tried to connect the mysql database service with the ip 127.0.0.1. And the connection was SUCCESSFUL.

Now I am confused what this 127.0.0.1 address is, my local PC or MySQL pod of Openshift container. How can I generate MySQL persistent with the HostIP, not with 127.0.0.1? I am afraid I missed the some procedure.

Your mysql pod havn't a public ip address, but you can use port forwarding.

With Eclipse:

How-To: https://blog.openshift.com/getting-started-eclipse-jboss-tools-openshift-online-3/

Download: http://marketplace.eclipse.org/content/jboss-tools-luna

With Openshift CLI:

$ oc port-forward <pod> [<local_port>:]<remote_port> [...[<local_port_n>:]<remote_port_n>]

such as

$ oc port-forward <pod> 3306:5000

Now you can connect the URL jdbc:mysql://127.0.0.1:5000/database. The mysql pod listen to on your local port 5000.
