Kubernates pod status: ImagePullBackOff

The status ImagePullBackOff means that a Pod couldn’t start because Kubernetes could not pull a container image. The ‘BackOff’ part indicates that Kubernetes will keep trying to pull the image, with an increasing back-off delay.

This can be happened because of two problems.

  1. The image or tag that which the pod referring doesn’t exist

In this case we need to recheck the image name, tag in the configuration and correct it if anything wrong.

  1. The credentials given for Docker registry is wrong.

In this case we can refer the following steps to configure the credentials.

That's all…
