Let's say we want to run 3 redis server on 3 nodes.

Step 1: compose yaml spec for deploy

cat > /tmp/spec.yaml <<!
appname: redis
entrypoints:
  singular:
    cmd: '--appendonly yes'
    publish:
      - 6379
!

Step 2: use eru-cli to deploy

eru-cli container deploy --pod eru --entry singular --image redis --network host --count 1 --deploy-method fill --nodes-limit 3  --memory 10M /tmp/spec.yaml

• --pod indicates node group on which you want to deploy;
• --entry indicates entrypoint written in spec to deploy;
• --image indicates docker image to pull and run with;
• --count 1 --deploy-method fill --node-limit 3 indicates to carry deployment on 3 nodes;
• --memory indicates memory limit for each container;
