Question

How do I create an image pull secret to pull a private image from Docker Hub

I’m not sure about the format of my image pull secret in Kubernetes Advanced Options.

When I “Create a new secret” I use a random secret name (or does the secret name has to be something specific?). Then I encode my docker hub username and password in base64 (username:password) as my “image pull secret data”. Is this the right approach?I get the following error message: “Error creating set”.

To create a docker secret, you can follow the example here:

https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/#create-a-secret-by-providing-credentials-on-the-command-line

Below the kubectl description there’s an example of how to reference it in your pod/deployment.

And now for a shameless plug: If you’re looking to use Amazon for your registry, I wrote a little tool that makes the integration easy: https://github.com/nabsul/k8s-ecr-login-renew
