Hello,
In this template you can create at the same time a MySQL server and
a Tomcat7. The Tomcat7 DataSource is configured with the environment
variables at the creation time.
But my case is that i have already deployed and configured the MySQL
server with:
oc new-app --name mydb mysql-persistent -p
DATABASE_SERVICE_NAME=xxx -p MYSQL_USER=xxx -p
MYSQL_PASSWORD=xxx -p MYSQL_DATABASE=xxx
And i want to deploy some separate build just with a Tomcat7, for
exaple with:
oc new-app --name myadmin
jboss-webserver30-tomcat7-openshift~http://<...>/MYADMIN.git
Or other posible situation could be to need several datasources
defined in context.xml pointing to diferent DDBB.
Thanks,
Andrés.

This template illustrates it:
https://github.com/jboss-openshift/application-templates/blob/master/webserver/jws30-tomcat7-mysql-persistent-s2i.json
Specifically this section defines the env variables that will be used
to define the datasource:
https://github.com/jboss-openshift/application-templates/blob/master/webserver/jws30-tomcat7-mysql-persistent-s2i.json#L454-L485
That should result in a datasource named ${APPLICATION_NAME}-mysql
being constructed using the various DB_XXX env variable content, where
"DB" comes from the "=DB" portion of the DB_SERVICE_PREFIX_MAPPING.
Kevin, is this behavior documented somewhere? I didn't see it in the
openshift image docs.

Hi,
In Openshift2, you could reference a MySQL DB from a Tomcat
cartridge just defining some environment variables, that were
replaced automatically in the JNDI definition at the context.xml.
<Resource name="jdbc/piadmin"
url="jdbc:mysql://*${OPENSHIFT_MYSQL_DB_HOST}*:*${OPENSHIFT_MYSQL_DB_PORT}*/*${OPENSHIFT_APP_NAME}*"
driverClassName="com.mysql.jdbc.Driver"
username="*${OPENSHIFT_MYSQL_DB_USERNAME}*"
password="*${OPENSHIFT_MYSQL_DB_PASSWORD}*"
auth="Container"
type="javax.sql.DataSource"
maxActive="20"
maxIdle="5"
maxWait="10000"
/>
In OpenShift3, this doesnt work. The tokens in context.xml are
not replaced by their corresponding environment variable
values. What is then the correct way to connect a JNDI
datasource in a Tomcat S2I like
jboss-webserver30-tomcat7-openshift?
Thanks,
Andrés.
