Docker Build Secret

[ThomasAunvik]

Allow using secrets trough environment variables and or file.

https://docs.docker.com/build/building/secrets/#using-build-secrets

Examples:

docker build --secret id=aws,src=$HOME/.aws/credentials .

docker build --secret id=kube,env=KUBECONFIG .

I've discovered you can do this if you use docker compose as the builder and then use build secrets from environment
