Google Cloud Storage cleanup
I got quite some storage usage since using Google Cloud Run for a growing number of applications in the last months.
So I need to cleanup a bit. Regularly.
If you have only a few applications this can be done manually on the Google Cloud Registry website: https://console.cloud.google.com/gcr/.
But I want to automate this.
First step is to get to know what is there:
This lists all services with container images in my europe registry folder.
Next list all images in one of the folders:
$IMAGE is the full name of the folder, i.e.
This returns a list of images with tags and date, i.e.:
To delete an image we need the SHA256 of the image.
Same command as before but with a
--format at the end.
The result is only the sha256 without tags and date. So quite hard to decide if I want to delete it. :(
Now delete one of the images, for safety reasons I chose the oldest one:
gcloud container images delete -q --force-delete-tags \ "gcr.io/$PROJECT_ID/helloword@sha256:b280f4f858492e50176470c26edb9cd4903cf69dc78070c806340edc1a1c84bc"
Doing this manually feels wrong and is quite time consuming.
But others had this problem before.
A good starting point for me was this gist: https://gist.github.com/ahmetb/7ce6d741bd5baa194a3fac6b1fec8bb7.
I made it a bit more verbose, but kept the system of deleting until a given date.
Some forks improved the gist to keep a given number of images.
