Rancher kubectl shell pod tries to pull an image from external dockerhub instead of pulling from private registry
This document (000021253) is provided subject to the disclaimer at the end of this document.
Environment
Rancher 2.6.x, 2.7.x and 2.8.x
Situation
- In the Rancher airgap environment, all the images including rancher-shell should get pulled from the default private registry, but there are some situations where few images are getting pulled from the external docker hub instead of the default private registry.
Resolution
- Verify the rancher "system-default-registry" property is correctly configured using the below command. If it's not, then follow the document [1] and re-configure the registry with the Rancher server.

b) modify the value section :
apiVersion: management.cattle.io/v3
customized: false
