Currently, you can't easily provide your own config file for the cni. Mounting a file from a configmap is readonly, and the magical find replace that sed does is inline against the existing file fails. Instead, I am proposing that we copy the file to a tempfile and modify that before we copy it to its destination.
I thought about perhaps having an environment variable for a custom template file, flag, or similar, but I think that actually that could cause more complexity in the entrypoint script, and I didn't want to change the behavior that much.
Sorry for the 'ergh' next to the sed comment, I wanted to show that I wasn't a fan of how this works, the sedding of config files 🤣. I appreciate why this is done here though.
