Docker image registration failed error on NSX-ALB virtual service

Products

• VMware

Issue/Introduction

Symptoms:

Virtual service is down with error - "State: Resources Reason: docker image registration failed"

Cause

• This issue occurs when a leader failover happens (most likely during an upgrade activity) and the necessary files are not replicated on the new controller leader node.
• i.e. /vol/pkgs/*/se_docker.tgz and se.pkg files are not replicated across the controller nodes during upgrade activity. (where * is the current NSX-ALB version)

Resolution

To resolve the issue, please follow either of the 2 options : -

1. We need to SCP the two files i.e. /vol/pkgs/21.1.*/se_docker.tgz and se.pkg file from the controller node where these files are present to the leader node. (where * is the current NSX-ALB version) OR
2. Re-Upload the image to controller (same image) - it will take care of replicating the images across nodes.

Additional Information

Impact/Risks:

Cannot create new virtual services.
