# Steps to run the Workflow application on Docker ## 1. Initialize Workflow Database `docker run -d -e CS_AUTHENTICATE={CS_AUTHENTICATE} -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** running docker with secured Cassandra DB `docker run -d -e CS_HOST=10.247.41.19 -e CS_AUTHENTICATE=true -e CS_USER=test -e CS_PASSWORD=secret -e CS_PORT=9160 onap/workflow-init:latest` running docker with unsecured Cassandra DB `docker run -d -e CS_HOST=10.247.41.19 -e CS_AUTHENTICATE=false -e CS_PORT=9160 onap/workflow-init:latest` or `docker run -d -e CS_HOST=10.247.41.19 -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. To check health information of application you can use option `-e SHOW_HEALTH={always}` **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`
