We're getting great results with this <ResourceLink> and <Resource> for
Tomcat connection pooling. The context.xml file is properly protected on
our snowflake tomcat servers.
But, we're looking to start using Docker to containerize our tomcat
servers. The easy and bad way is to commit this file to the container
image. It won't have the same protections that it does on the current
built-by-hand servers.
I'm sure I could work something out with environment variables or creating
a crazy docker-compose scheme or something.
But, if anyone has a way for managing this that they are satisfied
with/proud of, would you be willing to share the pattern?
