Running Hawk Container Edition Docker Containers in Standalone Mode

The containers of Hawk Container Edition components communicate with each other using the TCP Transport for Hawk.

To create a Hawk TCP cluster, Hawk Agent and Hawk Console connect to the Hawk Cluster Manager, which is the seed of the cluster. The connection configuration for these three components can be done using the environment variables for them. For more information on the environment variables available for each component, see Environment Variables for Hawk Container Edition Components . You can either provide these environment variables in Dockerfile or you can supply them in a single YAML file.

Docker provides a Compose tool for defining and running multi-container Docker applications. With the Compose tool you can provide all the configurations for all your containers in a single YAML file (docker-compose.yml). Then, using only a single command you can start the containers with the specified configurations. For more information about the Docker Compose tool, see the Docker Compose documentation.

Following is the sample content of a docker-compose.yml file that you can use in Hawk Container Edition: 

version: '3'
services:
  hawkclustermanager:
    image: hkce_clustermanager:2.0
    ports:
      - '2561:2561' 
    environment: 
      tcp_daemon_url: hawkclustermanager:2561
      tcp_self_url: hawkclustermanager:2561
      hawk_domain: tcpdomain
  hawkagent:
    image: hkce_agent:2.0
    ports:
      - '2551:2551'
      - '2571:2571'
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      tcp_daemon_url: hawkclustermanager:2561
      tcp_self_url: hawkagent:2551
      hawk_domain: tcpdomain
      ami_tcp_session: hawkagent:2571
      DOCKER_HOST: unix:///var/run/docker.sock
      config_path: /tibco.home/hkce/2.0/config/
      hma_plugin_dir: /tibco.home/hkce/2.0/plugin/
  hawkconsole:
    image: hkce_console:2.0
    environment:
      tcp_daemon_url: hawkclustermanager:2561
      tcp_self_url: hawkconsole:2551
      hawk_domain: tcpdomain
      hawk_console_repository_path: /tibco.home/hkce/2.0/repo
    ports:
      - '2589:2589'
      - '8083:8083'

Procedure

  1. Create the docker-compose.yml file with required configurations in a temporary folder.
    For more information about the Docker Compose tool, see the Docker Compose documentation.
  2. In the command line, browse to the docker-compose.yml file and run the following command to run all Hawk component containers with specified configurations: 
    docker-compose up  -d
  3. You can verify that all containers are running by using the following command: 
    docker ps

What to do next

If you have Hawk console container running, you can access it at http://<Console_host_IP>:<Host_port>/HawkConsole.
