+This example depends on the existence of a "php" imagestream in the "openshift" namespace. If you do not have one defined, you can create it by using one of the imagestream definition files found here: |
|
| 1 |
+https://github.com/openshift/origin/tree/master/examples/image-streams |
|
| 2 |
+ |
|
| 3 |
+ oc create -f image-streams-centos7.json -n openshift |
|
| 4 |
+ |
|
| 5 |
+(you will need to be a cluster admin to create imagestreams in the openshift namespace) |
|
| 6 |
+ |
|
| 7 |
+To use this example, instantiate it with |
|
| 8 |
+ |
|
| 9 |
+ oc new-app -f wordpress-mysql.json |
|
| 10 |
+ |
|
| 11 |
+Take note of the `DATABASE_PASSWORD` that is displayed. |
|
| 12 |
+ |
|
| 13 |
+Wait for the build of the new wordpress image to complete. You can monitor the build by running |
|
| 14 |
+ |
|
| 15 |
+ oc get builds --watch |
|
| 16 |
+ |
|
| 17 |
+Once the wordpress build completes, determine the wordpress and |
|
| 18 |
+mysql service IPs by running: |
|
| 19 |
+ |
|
| 20 |
+ oc get svc |
|
| 21 |
+ |
|
| 22 |
+Navigate to `<wordpress service ip>:8080` in your browser. You will |
|
| 23 |
+be prompted to setup wordpress. |
|
| 24 |
+ |
|
| 25 |
+For the database hostname, provide the mysql service ip. |
|
| 26 |
+ |
|
| 27 |
+For the database username, enter "wordpress" |
|
| 28 |
+ |
|
| 29 |
+For the database password, provide the password generated when you |
|
| 30 |
+instantiated the template. |
|
| 31 |
+ |
|
| 32 |
+You should not need to change any other values. |
|
| 33 |
+ |
|
| 34 |
+ |
|
| 35 |
+Note: this template uses an EmptyDir volume type for database storage. This type of storage is not persisted. If you want to ensure the database content is not lost, modify the template to user a persistent volume claim type instead. |
