Azure Container registry - Cleanup space

Question

Hello,

I'm using the Azure Container registry (SKU: Basic) for publishing my Docker Linux Web App from Visual Studio.
Everything works fine but every time I do a deployment the Azure Container registry space keeps growing.

I only have one repository which I also fully cleaned up (I deleted all the tags).
After the cleanup the repository still shows that it has over 300 manifests and the used space was not reduced :(.

How can I remove all deployments I did from the Azure Container registry except the last one ?

Thx a million.

Hello @Markus Jessl ,
How were you trying to delete the tags ?
Can you take a look at the below article:
https://learn.microsoft.com/en-us/azure/container-registry/container-registry-delete#automatically-purge-tags-and-manifests-preview
https://learn.microsoft.com/en-us/azure/container-registry/container-registry-delete

Sometimes, the reason why the used storage didn’t decrease probably because of the untagged manifests didn’t get to be discovered. There are couple of different commands mentioned here in github - take a look at those.
For example , If you are using the purge command and if you don't include "--untagged" flag - which results in deleting the tags but not the manifests themselves and not releasing the space as a result

Finally , take a look at the retention policies: https://learn.microsoft.com/en-us/azure/container-registry/container-registry-retention-policy
