All of a sudden, I cannot deploy some images which could be deployed before. I got the following pod status:
[root@webdev2 origin]# oc get pods
NAME READY STATUS RESTARTS AGE
arix-3-yjq9w 0/1 ImagePullBackOff 0 10m
docker-registry-2-vqstm 1/1 Running 0 2d
router-1-kvjxq 1/1 Running 0 2d
The application just won’t start. The pod is not trying to run the container. From the Event page, I have got Back-off pulling image "172.30.84.25:5000/default/arix@sha256:d326. I have verified that I can pull the image with the tag with docker pull.
I have also checked the log of the last container. It was closed for some reason. I think the pod should at least try to restart it.
I have run out of ideas to debug the issues. What can I check more?
