Ambari Docker Compose Runtime

Sample Docker Compose files for running Ambari with PostgreSQL or MySQL, and a local repo (optional)

Usage

  1. Define AMBARI_BUILD (eg. 2.6.1) and AMBARI_FLAVOR (eg. centos7) variables (look for available ambari-server and ambari-agent images on Docker Hub)
  2. Create password.dat with the password for the ambari DB user
  3. Run Ambari: 
    docker-compose -p ambari -f server.yaml -f agent.yaml -f db/postgres.yaml up -d
  4. Scale the cluster by adding new agent nodes: 
    docker-compose -f ... scale agent=2

Notes

  • Define the set of compose files to be used in the COMPOSE_FILE environment variable to avoid having to type all of them for each command. 
    COMPOSE_FILE=server.yaml:agent.yaml:db/postgres.yaml:repo.yaml
  • Most Ambari settings are defined in *.env files. These are converted to the real config files by envtoconf invoked by the flokkr/launcher. This allows mixing in settings from the compose files or other sources.
  • For using Ambari with MySQL, download MySQL Connector/J, and define the jar's location on the host in the MYSQL_JDBC_DRIVER variable. The file will be mounted in Ambari Server's container.
  • If some stack is available locally, point REPO_DIR to it and add repo.yaml the list of compose files. Set base URLs in Ambari to http://repo/...
