Janos is a K8s migration tool that update your manifests in order to be compatible with newer versions. It does not work with Helm templates, just with pure yaml files.
TLDR; Have your Kuberenetes manifests up to date
Janos will convert all your manifest files, updating it inplace. If you pass a directory as a parameter, it will do a recursive search. All comments are removed, and the file formatting may change.
Build the image before running the script, because it will be executed inside the container.
# Build image
make build
# Copy entrypoint script to /usr/local/bin
make installjanos {-d|-f}
-f file The file to be converted.
-d dir The directory with the yaml files to be converted.All the rules are in the file migration.js.
