delete all images in container registry - see: https://stackoverflow.com/questions/67338215/cloud-function-build-error-failed-to-get-os-from-config-file-for-image

delete_all_container_images.sh

#!/bin/sh

# e.g. CONTAINER_REGISTRY=asia.gcr.io/your-project-name/gcf/asia-northeast1
CONTAINER_REGISTRY=`WRITE YOUR REGISTRY NAME`
IMAGE_LIST=`gcloud container images list --repository=$CONTAINER_REGISTRY | awk 'NR!=1'`

for line in $IMAGE_LIST; do
  gcloud container images delete "$line/worker" --quiet & gcloud container images delete "$line/cache" --quiet &
done

wait

Yes. That’s right.
I could not find any documentations but I checked by deleting small project.

@contributorpw Just to confirm before I break our whole production backend; I can safely just remove all the image/containers to free up the function mess created by pre firebase-cli 9.14? Do I NEED to redeploy the functions after this, or are you just saying that when new functions are deployed the Containers are lighter

@mattbushell

It works for my production fine:

1. Run the script above
2. Re-deploy production as a normal deployment flow

Now I'm not sure if they remain lighter. They grow over time.

Sorry for this noobie question but...how should I run this script? Is like a simple bash script? copy/paste on any folder of my current pc, and simply executed with doble click?

@EricBattle

You need to configure the gcloud before run it. Look at the first row of the script. It's #!/bin/sh. You have to use a sh/bash/zsh.

Thx @contributorpw ! So should I execute those lines on Cloud shell from Google Gloud Platform?

@contributorpw Thank you for answering.

@EricBattle
It doesn't matter if you are using a Cloud shell or a local machine as long as you can run the gcloud command.

I could see there were many of the images tagged with the latest tag or with the name of my functions, but there were also a lot of untagged images in the same folders that I couldn't get rid of just by re-deploying with the latest firebase cli or using the script.

So I ended up with this:

#!/bin/sh

# e.g. CONTAINER_REGISTRY=asia.gcr.io/your-project-name/gcf/asia-northeast1
CONTAINER_REGISTRY='WRITE YOUR REGISTRY NAME'
LIMIT='unlimited' # change to LIMIT=1 if you want to test small
# DRY_RUN=1 # uncomment this to only list, but not delete
IMAGE_LIST=`gcloud container images list --repository=$CONTAINER_REGISTRY --limit=$LIMIT --format="get(name)"`

for image in $IMAGE_LIST; do
  echo "Image 1: $image"
  DIGEST_LIST=`gcloud container images list-tags $image --format="get(digest)"`
  for digest in $DIGEST_LIST; do
    echo "  -> Digest: $digest"
    if [ -z "$DRY_RUN" ]; then
      gcloud container images delete $image@$digest --force-delete-tags --quiet > /dev/null 2>&1
    fi
  done

  SUB_LIST=`gcloud container images list --repository=$image --format="get(name)"`
  for sub in $SUB_LIST; do
    echo "  Image 2: $sub"
    DIGEST_LIST=`gcloud container images list-tags $sub --format="get(digest)"`
    for digest in $DIGEST_LIST; do
      echo "    -> Digest: $digest"
      if [ -z "$DRY_RUN" ]; then
        gcloud container images delete $sub@$digest --force-delete-tags --quiet > /dev/null 2>&1
      fi
    done
  done
done

Hope it helps. Thanks @kichiemon.

Anyone knows where can I found the CONTAINER_REGISTRY name? :(

@EricBatlle Find the Container Registry in the cloud console for your project, then navigate the full path and you can copy-paste from the breadcrumb navigator :)
