Private docker registry

Until #1459 is addressed, you can use a private docker registry for your Predictor images by following this guide.
Local
When running Cortex locally, you can use private Docker images by running docker login and then docker pull <your_image>. The Docker image will be present on your machine, and will be accessible by Cortex the next time you run cortex deploy.
Cluster
Step 1
Install and configure kubectl (instructions).
Step 2
Set the following environment variables, replacing the placeholders with your docker username and password:
1
DOCKER_USERNAME=***
2
DOCKER_PASSWORD=***
Copied!
Run the following commands:
1
kubectl create secret docker-registry registry-credentials \
2
  --namespace default \
3
  --docker-username=$DOCKER_USERNAME \
4
  --docker-password=$DOCKER_PASSWORD
5
​
6
kubectl patch serviceaccount default --namespace default \
7
  -p "{\"imagePullSecrets\": [{\"name\": \"registry-credentials\"}]}"
Copied!
Updating your credentials
First remove your old docker credentials from the cluster:
1
kubectl delete secret --namespace default registry-credentials
Copied!
Then repeat step 2 above with your updated credentials.
Removing your credentials
To remove your docker credentials from the cluster, run the following commands:
1
kubectl delete secret --namespace default registry-credentials
2
​
