Upgrading

Due to how Dokku tracks app changes, tracking the latest image tag will result in no changes being detected. Instead we use the image digest.

export SHOKKU_VERSION=latest

docker pull "repo/shokku:$SHOKKU_VERSION"

dokku git:from-image shokku $(docker inspect --format='{{index .RepoDigests 0}}' "repo/shokku:$SHOKKU_VERSION")
