How to debug “ImagePullBackOff”?

Question

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

I forgot to push the image tagged 1.0.8 to the ECR (AWS images hub)... If you are using Helm and upgrade by:

helm upgrade minta-user ./src/services/user/helm-chart

make sure that image tag inside values.yaml is pushed (to ECR or Docker Hub, etc) for example: (this is my helm-chart/values.yaml)

replicaCount: 1

image:
   repository:dkr.ecr.us-east-1.amazonaws.com/minta-user
   tag: 1.0.8

you need to make sure that the image:1.0.8 is pushed!
