we deploy jasperreport (bitnami image from here: https://hub.docker.com/r/bitnami/jasperreports)

So far so good, everything works well. We made it simple (no volume) for the moment.

The next step is to enable cas login. To do so, We need to copy (inject?) a file 'applicationContext.xml' into the WEBINF directory of the tomcat.

That is where I don't know how to do that in my deploy.yml file.

What would be the best practice here ?

Here is the deploy.yml we have so far (working well):
