I'm using docker-compose and I have a step that pulls the latest postgres. But I started getting the following error:
You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limits.
It been a day since I last pulled something but I still get this error. How much more time should I wait before I can pull again? I'm behind workplace proxy doing anonymous pulls.
The pull limit is a rolling limit that should reset parts of the quota 6 hours after that part of the quota was used. E.g. of you do 25 pulls every hour, then after the 4th hour, you need to wait 2 hours for the first 25 pulls to be added back to your quota.
Anonymous pulls are based on the IP performing the pull, and if you are behind a proxy or NAT, that may mean others on the same network are included in your limit. So if you see the limit continue to be reached after 6 hours, there are most likely others on the network pulling from hub with your same source IP from the NAT.
Logging in with a free Hub account in doubles this limit and is based on login rather than source IP, allowing different users behind a NAT to pull without conflicting with each other.
Therefore you should include credentials with your pull commands, using docker login or the equivalent for the tool you use to pull.
Another workaround is to pull the image locally once & push it to your local docker repository. & then update your image properties to point to your local repository.
example: I faced an issue while using the "busybox" image. During some debugging I hit the limit. This was in my deployment.yaml file for one of the pod spec.
image: busybox
Then I pulled the images locally using my credentials & pushed it to our local (internally hosted) docker repository. Once pushed, updated the deployment.yaml file with updated image link.
image: <LOCAL DOCRER REPO URL>/busybox
