monasca/thresh repository overview

⁠monasca-thresh Dockerfile

This image has a containerized version of the Monasca Threshold Engine. For more information on the Monasca project, see the wiki⁠.

Sources: monasca-thresh⁠ · monasca-docker⁠ · Dockerfile⁠

⁠Tags

Images in this repository are tagged as follows:

latest: refers to the latest stable point release, e.g. 1.7.0
1.0.0, 1.0, 1: standard semver tags based on git tags in the official repository⁠.
newton, ocata, etc: named versions following OpenStack release names built from the tip of stable/RELEASENAME branches in the repository
master, master-DATESTAMP: unstable testing builds from the master branch, these may have features or enhancements not available in stable releases, but are not production-ready.

Note that features in this Dockerfile, particularly relating to running in Docker and Kubernetes environments, require code that has not yet been made available in a tagged release. Until this changes, only master images may be available and latest may point to master images.

⁠Usage

The Threshold engine requires configured instances of MySQL, Kafka, Zookeeper, and optionally Storm monasca-api⁠. In environments resembling the official docker-compose⁠ or Kubernetes⁠ environments, this image requires little to no configuration and can be minimally run like so:

docker run monasca/thresh:latest

⁠Running with and without Storm

The Threshold Engine can be run in two different modes, with Storm Daemons or without Storm Daemons. If run with the Storm Daemons, multiple Storm Supervisor containers can be used with more than one worker process in each. With no Storm Daemons, only a single Threshold Engine container can be run with a single worker process.

The default docker-compose.yml file is configured to run without Storm. To change docker-compose.yml to run with Storm, delete the thresh service entry and replace it with the below:

  storm-nimbus:
    image: monasca/storm:1.0.3
    command: storm nimbus
    environment:
      STORM_LOCAL_HOSTNAME: "storm-nimbus"
      WORKER_LOGS_TO_STDOUT: "true"
    depends_on:
      - zookeeper
      - kafka

  storm-supervisor:
    image: monasca/storm:1.0.3
    command: storm supervisor
    depends_on:
      - storm-nimbus
      - zookeeper
      - kafka

  thresh-init:
    image: monasca/thresh:master
    environment:
      STORM_WAIT_RETRIES: 50
    depends_on:
      - zookeeper
      - storm-nimbus
      - storm-supervisor
