Deploy 2 data center nodes of Bitbucket in docker

[#1]

Hello!

In this article I will show you how you can deploy 2 data center nodes of Bitbucket in your local environments using the docker image provided by Atlassian.

This deployment will not include the load balancer because I need these nodes for app development to check if my app works properly in Data Center environment. That is why I always connect to a certain node.

First, you need to create this docker-compose.yml file:

version: '3'

services:
  bb_node_1:
    depends_on:
      - postgresql
    image: atlassian/bitbucket:latest
    networks:
      - bbnet
    volumes:
      - /Users/alexm/projects/prometheus/bitbucket/shared:/var/atlassian/application-data/bitbucket/shared
    ports:
      - '7990:7990'
      - '8000:5005'
    environment:
      - 'JDBC_URL=jdbc:postgresql://postgresql:5432/bbdb'
      - 'JDBC_USER=bb'
      - 'JDBC_PASSWORD=jellyfish'
      - 'JDBC_DRIVER=org.postgresql.Driver'
      - 'JVM_MINIMUM_MEMORY=2048m'
      - 'JVM_MAXIMUM_MEMORY=4096m'
      - 'JVM_SUPPORT_RECOMMENDED_ARGS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005'
      - 'HAZELCAST_GROUP_NAME=bb_group'
      - 'HAZELCAST_GROUP_PASSWORD=1234'
      - 'HAZELCAST_NETWORK_MULTICAST=true'

  bb_node_2:
    depends_on:
      - postgresql
    image: atlassian/bitbucket:latest
    networks:
      - bbnet
    volumes:
      - /Users/alexm/projects/prometheus/bitbucket/shared:/var/atlassian/application-data/bitbucket/shared
    ports:
      - '7991:7990'
      - '8001:5005'
    environment:
      - 'JDBC_URL=jdbc:postgresql://postgresql:5432/bbdb'
      - 'JDBC_USER=bb'
      - 'JDBC_PASSWORD=jellyfish'
      - 'JDBC_DRIVER=org.postgresql.Driver'
      - 'JVM_MINIMUM_MEMORY=2048m'
      - 'JVM_MAXIMUM_MEMORY=4096m'
      - 'JVM_SUPPORT_RECOMMENDED_ARGS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005'
      - 'HAZELCAST_GROUP_NAME=bb_group'
      - 'HAZELCAST_GROUP_PASSWORD=1234'
      - 'HAZELCAST_NETWORK_MULTICAST=true'

  postgresql:
    image: postgres:9.5-alpine
    networks:
      - bbnet
    #volumes:
    #  - postgresqldata:/var/lib/postgresql/data
    ports:
      - '5432:5432'
    environment:
      - 'POSTGRES_USER=bb'
      # CHANGE THE PASSWORD!
      - 'POSTGRES_PASSWORD=jellyfish'
      - 'POSTGRES_DB=bbdb'
      - 'POSTGRES_ENCODING=UNICODE'
      - 'POSTGRES_COLLATE=C'
      - 'POSTGRES_COLLATE_TYPE=C'
    logging:
      # limit logs retained on host to 25MB
      driver: "json-file"
      options:
        max-size: "500k"
        max-file: "50"

volumes:
  postgresqldata:
    external: false

networks:
  bbnet:
    driver: bridge

Change ‘/Users/alexm/projects/prometheus/bitbucket/shared’ to the folder path where all shared data for your nodes should be placed.

Move to the folder where you created the file and run it with this command:

docker-compose up

As a result you will have two Bitbucket nodes up. The first node will be running on port 7090 and the second node will be running on port 7091.

Also you will be able to connect with a debug session to the nodes using ports 8000 for node 1 and 8001 for node 2.

If you have problem with including the second node to the cluster just restart the container with the second node.

Thanks for sharing. Couldn't resist and tried this out ;)

2 Observations:

1. Node 2 doesn't start up while Node 1 has the shared home locked

2. Trying to start Node 2 after Node 1 starts up kills Node 1

bb_node_2_1   | 2022-01-20 02:43:02,661 INFO  [main]  c.a.b.i.b.BitbucketServerApplication Started BitbucketServerApplication in 4.13 seconds (JVM running for 5.017)

bb_node_1_1   |

bb_node_1_1   | Stopping bundled Elasticsearch

bb_node_1_1   | Bundled Elasticsearch has stopped

bitbucket-docker-dc_bb_node_1_1 exited with code 0

Any ideas?

NB: I added

- 'ELASTICSEARCH_ENABLED=false' 

to node_2 env to avoid 2 ES bundled instances starting at the same time.
