Replacing initcontainer with custom dind image container

[rekha-prakash-maersk]

The pods with initcontainer takes 1 minute to start up, whereas the pod with only 2 container ( runner and custom dind image) only takes 10 seconds to spin up. I like to understand is there any specific reason behind having this initcontainer ?

I believe the init container is just copying files from the runner container to the dind container. See this thread: https://github.com/actions/actions-runner-controller/discussions/2944
