+OpenShift 3 Database Examples
+=============================
+
+This directory contains example JSON templates to deploy databases in OpenShift.
+They can be used to immediately instantiate a database and expose it as a
+service in the current project, or to add a template that can be later used from
+the Web Console or the CLI.
+
+The examples can also be tweaked to create new templates.
+
+
+## Ephemeral vs. Persistent
+
+For each supported database, there are two template files.
+
+Files named `*-ephemeral-template.json` use
+"[emptyDir](https://docs.openshift.org/latest/dev_guide/volumes.html)" volumes
+for data storage, which means that data is lost after a pod restart.
+This is tolerable for experimenting, but not suitable for production use.
+
+The other templates, named `*-persistent-template.json`, use [persistent volume
+claims](https://docs.openshift.org/latest/architecture/additional_concepts/storage.html#persistent-volume-claims)
+to request persistent storage provided by [persistent
+volumes](https://docs.openshift.org/latest/architecture/additional_concepts/storage.html#persistent-volumes),
+that must have been created upfront.
+
+
+## Usage
+
+### Instantiating a new database service
+
+Use these instructions if you want to quickly deploy a new database service in
+your current project. Instantiate a new database service with this command:
+
+    $ oc new-app /path/to/template.json
+
+Replace `/path/to/template.json` with an appropriate path, that can be either a
+local path or an URL. Example:
+
+    $ oc new-app https://raw.githubusercontent.com/openshift/origin/master/examples/db-templates/mongodb-ephemeral-template.json
+
+The parameters listed in the output above can be tweaked by specifying values in
+the command line with the `-p` option:
+
+    $ oc new-app examples/db-templates/mongodb-ephemeral-template.json -p DATABASE_SERVICE_NAME=mydb -p MONGODB_USER=default
+
+Note that the persistent template requires an existing persistent volume,
+otherwise the deployment won't ever succeed.
+
+
+### Adding a database as a template
+
+Use these instructions if, instead of instantiating a service right away, you
+want to load the template into an OpenShift project so that it can be used
+later. Create the template with this command:
+
+    $ oc create -f /path/to/template.json
+
+Replace `/path/to/template.json` with an appropriate path, that can be either a
+local path or an URL. Example:
+
+    $ oc create -f https://raw.githubusercontent.com/openshift/origin/master/examples/db-templates/mongodb-ephemeral-template.json
+    template "mongodb-ephemeral" created
+
+The new template is now available to use in the Web Console or with `oc
+new-app`.
+
