+# Steps to run the Workflow application on Docker
+
+## 1. Initialize Workflow Database
+
+`docker run -d -e CS_HOST={HOST} -e CS_PORT={PORT} -e CS_USER={USER} -e CS_PASSWORD={PASSWORD} {INIT_IMAGE}`
+
+This is done only once to initialize the DB schema.
+
+**Example** 
+
+`docker run -d -e CS_HOST=10.247.41.19 -e CS_USER=test -e CS_PASSWORD=secret -e CS_PORT=9160 onap/workflow-init:latest`
+
+## 2. Start Backend
+
+`docker run -d -e JAVA_OPTIONS={JAVA_OPTIONS} -e CS_HOSTS={COMMA_SEPARATED_HOSTS} -e CS_PORT={PORT} 
+-e CS_USER={USER} -e CS_PASSWORD={PASSWORD} -p {HOST_PORT}:{APPLICATION_PORT} {BACKEND_IMAGE}`
+
+or, if Cassandra authentication is not required
+
+`docker run -d -e JAVA_OPTIONS={JAVA_OPTIONS} -e CS_HOSTS={COMMA_SEPARATED_HOSTS} -e CS_PORT={PORT} 
+-e CS_AUTHENTICATE=false -p {HOST_PORT}:{APPLICATION_PORT} {BACKEND_IMAGE}`
+
+The server listens on 8080 by default, but it is possible to change the application port by passing 
+`-e SERVER_PORT={PORT}` to Docker _run_ command.
+
+**Example**
+
+`docker run -d -e JAVA_OPTIONS="-Xmx128m -Xms128m -Xss1m" -e CS_HOSTS=10.247.41.19,10.247.41.20 
+-e CS_PORT=9042 -e CS_AUTHENTICATE=false -p 8080:8080 onap/workflow-backend:latest`
