Example Kubernetes yaml to pull a private DockerHub image

gistfile1.txt

Step by step how to pull a private DockerHub hosted image in a Kubernetes YML.

export DOCKER_REGISTRY_SERVER=https://index.docker.io/v1/
export DOCKER_USER=Type your dockerhub username, same as when you `docker login`
export DOCKER_EMAIL=Type your dockerhub email, same as when you `docker login`
export DOCKER_PASSWORD=Type your dockerhub pw, same as when you `docker login`

kubectl create secret docker-registry myregistrykey \
  --docker-server=$DOCKER_REGISTRY_SERVER \
  --docker-username=$DOCKER_USER \
  --docker-password=$DOCKER_PASSWORD \
  --docker-email=$DOCKER_EMAIL

If your username on DockerHub is DOCKER_USER, and your private repo is called PRIVATE_REPO_NAME, and the image you want to pull is tagged "latest", create this dummy.yaml file:

apiVersion: v1
kind: Pod
metadata:
  name: foo
spec:
  containers:
    - name: whatever
      image: index.docker.io/DOCKER_USER/PRIVATE_REPO_NAME:latest
      imagePullPolicy: Always
      command: [ "echo", "SUCCESS" ]
  imagePullSecrets:
    - name: myregistrykey


Then run:
kubectl create -f dummy.yaml

I struggled getting this exact scenario to work for a while. [except on Windows] These steps finally got all the right pieces in the right places and it worked.
