resolve-tags

resolve-tags replaces tagged images in your Kubernetes yamls with their corresponding digests, and prints the new manifest to STDOUT. It can be run as a binary or installed as a kubectl plugin.

Quickstart

Running the resolve-tags kubectl plugin

You can run the plugin as follows:

kubectl plugin resolve-tags -f <path to file>

To apply subsitutions as you would using kubectl apply -f, you can run:

kubectl plugin resolve-tags -f <path to file> --apply true

Note: The plugin can only resolve one file at a time. If you need to resolve more than one file at the time, consider using the binary.

Running the resolve-tags binary

You can run the resolve-tags binary as follows:

resolve-tags -f <path to file> -f <path to another file>

To apply subsitutions using kubectl apply -f, you can run:

resolve-tags -f <path to file> -a

This will apply the digest to the objects defined in file.
