Secure CockroachDB Cluster, inspired by Docker tutorial

Simple 3 node secure CockroachDB cluster with HAProxy acting as load balancer

  • UPDATED: 11/11/20

Prerequisites:

Services

  • roach-0 - CockroachDB node
  • roach-1 - CockroachDB node
  • roach-2 - CockroachDB node
  • lb - HAProxy acting as load balancer
  • roach-cert - Holds certificates as volume mounts

Getting started

If you are using Google Chrome as your browser, you may want to navigate here chrome://flags/#allow-insecure-localhost and set this flag to Enabled.

  1. docker-compose run web django-admin startproject composeexample .
14:32 $ docker-compose run web django-admin startproject composeexample .
Starting roach-cert ... done
Starting roach-0    ... done
  1. because operation order is important, execute ./up.sh instead of docker-compose up
    • monitor the status of services via docker-compose logs
    • in case you need to adjust something in composexample/settings.py, you can use docker-compose logs web, docker-compose kill web, docker-compose up -d web to debug and proceed.
  2. visit the CockroachDB Admin UI and login with username test and password password
  3. visit the HAProxy UI

Open Interactive Shells

docker exec -ti roach-0 /bin/bash
docker exec -ti roach-1 /bin/bash
docker exec -ti roach-2 /bin/bash
docker exec -ti lb /bin/sh

# shell
docker exec -ti roach-cert /bin/sh

# cli inside the container
cockroach sql --certs-dir=/certs --host=roach-0

# directly
docker exec -ti roach-0 cockroach sql --certs-dir=/certs --host=roach-0
