Currently you are able to edit the Deployment of an RHDH instance and manually add sidecar containers. For the Lightspeed Backend Plugin we would benefit from having these sidecar containers automatically spun up if the plugin is installed. We are trying to leverage upstream containers that are written in Python from our Backstage Plugin, and since these plugins are written in .js/.ts we need to be able to have these Python containers spun up and available.

From my research, currently the Ansible team is leveraging sidecar containers alongside their plugins, however, their instructions state you have to manually add them to the pod whereas we are requesting it be done if the plugin is installed (and tear down the container if it is uninstalled for instance).

This container will be expecting environment variables to be passed through it so that will be a requirement as well.
