How to deal with ImagePullBackOff error in Azure Kubernetes

ImagePullBackOff in Azure Kubernetes indicates that Kubernetes could not pull a container image. In fact, the ‘BackOff’ part here indicates that Kubernetes is going to keep attempting to pull the image, with an increasing delay.

According to our experts, this may occur due to several reasons. Here are a couple of troubleshooting tips to resolve the issue:

• Check the image name and tag:

  Ensure the image name and tag mentioned in the Kubernetes deployment file matches the image in the container registry.
• Verify image is present:

  Ensure the image is present in the registry and accessible to the cluster.
• Update the image tag:

  In case the image has been updated in the registry, we have to update the tag in the Kubernetes deployment file as well.
• Configure the container registry credentials:

  We have to configure the credentials in the Kubernetes cluster by configuring the credentials in the pod definition file or via a secret in the cluster.
• Check the network connection:

  In case of network issues, the image pull will fail.
• Check the resource limits:

  Verify the resources do not exceed the limits of the cluster.
• Clear the image cache:

  A corrupted image cache can result in the “ImagePullBackOff” error. Hence, clear the cache.
• Restart the pod:

  If none of the above tips work, try restarting the pod. In some cases, this can resolve the issue.
