Docker

Start the container and link it with your backend (alternatively, use Docker networks):

docker run -d --name nginx-basic-auth -p 8087:8087 \
  --link backend:backend \
  -e FORWARD_HOST=backend \
  -e FORWARD_PORT=3000 \
  xscys/nginx-sidecar-basic-auth

OpenShift Sidecar Usage

Add the sidecar container next to your application container in your deployment configuration:

- image: xscys/nginx-sidecar-basic-auth
  imagePullPolicy: Always
  name: auth-proxy
  ports:
    - containerPort: 8087
      protocol: TCP
