This past November, Docker Hub started enforcing rate limits for image pulls for anonymous and free account users.
To ensure that your docker pulls on Kubernetes are authenticated, first create a docker-registry secret to hold your Docker Hub credentials:
kubectl create secret docker-registry <secret_name> \
--docker-server=docker.io \
--docker-username=<username> \
--docker-password=<password> \
--docker-email=<email>Then you’ll need to patch your default service account to include the secret:
imagePullSecrets:
- name: <secret_name>If you’re on OpenShift, you can use the following handy command to link the secret to the service account instead:
oc secrets link default <secret_name> --for=pullJust a quick post on stale branches on this Black Friday. Like old docker images, Git branches that are no longer needed inevitably starts to accumulate as a by-product of everyday development.
To remove these local branches, I use the following commands:
> git remote prune origin
> git branch -vv | grep "origin/.*: gone]" | awk '{print $1}' | xargs git branch -DAnd if you need to remove old docker images, check out my post on that here.
