Version: Release 22.1

Multi-Node Docker Deployments

The production setup for Release as described here can be done using Docker Compose as below.

This is a sample, you can follow this approach to setup the database and other infrastructure of your choice.

Note 1: For production deployments it is advised to use Kubernetes to orchestrate the deployment of the applications. Docker compose is not ideal for production setup. Proceed at your own risk. Note 2: For HA setup to work, you need to mount a licence file or provide an environment variable XL_LICENSE with a licence text converted to base64 for the Release instances

Note 3: The folders you mount needs to be owned by user 10001, for example, you can run sudo chown -R 10001 xl-release if you are going to mount directories under $PWD/xl-release folder.

Setup​

The setup includes

  • A load balancer with HaProxy
  • PostgreSQL database single node setup
  • Release nodes

Limitations​

  • Release should have at least 3 nodes to form a valid cluster
  • The database setup is for demo purposes, use your own setup or use an external database
  • The MQ setup is for demo purposes, use your own setup or use an external MQ
  • The HAproxy setup is for demo purposes, use your own setup

Steps​

Follow the steps mentioned below to deploy the sample:

  1. Save the following Docker Compose sample in your working directory, modifying it as needed.

  2. You can also save this run.sh file. Change the passwords as required.

  3. You can view the logs of individual containers using the docker logs <container_name> -f command

  4. You can access Release UI at http://localhost:8081

  5. To shutdown the setup you can run below
