I was using
skaffold dev to do my development work locally. Skaffold allows you to run your kubernetes cluster locally
without requiring building and pushing your container image anywhere. Instead it builds it locally
and deploys patched changes
files (rails stack) and map them over. However, for all other file extensions, skaffold by default will attempt to rebuild
the image and restart it instead of hot patching the files only.
I noticed, whenever interacting with git, it would cycle through that entire process and generally slow things down
for a minute or so. This was both annoying and frequent enough for me to investigate if its possible to ignore
certain files and directories. The good thing is that not only is it supported but its not even required in skaffold.
Skaffold honors anything within the
.dockerignore file. So to fix the issue, I simply created one and added the .git folder there.
.dockerignore file looks like this:
# Ignore the .git folder entirely .git log/ *.tmp *.temp
