delete all images in Azure Container Registry except the last two

[exitista]

Hello, how are you?

I want to delete all images in Azure Container Registry except the last two. I was looking for an script for do so but I only find to delete images older than X days. This is not possible for my situation because some days there are a lot of images created and other days only one.

Somebody has any idea?

Thanks in advance

Regards

@SteveLasker - should we enhance to count rather than ago ? https://docs.microsoft.com/en-us/azure/container-registry/container-registry-auto-purge

Any luck with this request? When this will be implemented?

Thanks for any update on this - I am having to write something custom for this at the moment.

Any update here? Thanks!

Any update on this? They added a --keep flag, but I get unknow flag, so has this been implemented? https://docs.microsoft.com/en-us/azure/container-registry/container-registry-auto-purge#use-the-purge-command Thanks

Any progress here? Something like this could really help me out. I'd like to be able to set a rule like e.g: Allow a maximum of 5 images in a repository. If a sixth image is added, delete the oldest one.

PURGE_CMD="mcr.microsoft.com/acr/acr-cli:0.4 purge \
  --filter 'samples/devimage1:.*' --filter 'samples/devimage2:.*' \
  --ago 0d --keep 5 --untagged"

az acr task create --name weeklyPurgeTask \
  --cmd "$PURGE_CMD" \
  --schedule "0 1 * * Sun" \
  --registry myregistry \
  --context /dev/null

You can create a task that will clean it out every week. More info: https://docs.microsoft.com/en-us/azure/container-registry/container-registry-auto-purge#example-scheduled-purge-of-multiple-repositories-in-a-registry The important bit is to add the --keep 5 part to the command

@themegaphoenix We are investing in an auto-purge capability that will allow you to define the purge policy based on various criteria including keeping certain number of images. Unfortunately, though because of other priorities we had to de-prioritize that work and now the ETA is mid 2022. We do not have plans to enhance the current purge command with additional capabilities before that. Your option will be to write a custom script to determine the images you want to keep.

@toddysm: Do you have any example on how to achieve this? I tried doing this using the --filter argument with a positive lookahead (to basically delete everything except). E.g:

apollo:(?!1302|1301|1304)

Which should return everything except the tags 1302, 1301 and 1304. But the regex library used by Go doesn't support positive lookahead:

invalid or unsupported Perl syntax: `(?!`

The only way I can think of is getting a list of the tags and run the delete by tag myself. I'm wondering if you have any other ideas.. ;-)

What is the status of this?
