handcraftedbits/nginx-unit-bitbucket repository overview

⁠NGINX Host Bitbucket Unit

A Docker⁠ container that provides an Atlassian Bitbucket⁠ unit for NGINX Host⁠.

⁠Features

• Atlassian Bitbucket 4.14.2
• NGINX Host SSL certificates are automatically imported into Bitbucket's JVM so Atlassian application links can easily be created

⁠Usage

⁠Prerequisites

⁠Database

Make sure you have a supported database⁠ available either as a container or standalone.

⁠NGINX_UNIT_HOSTS Considerations

It is important that the value of your NGINX_UNIT_HOSTS environment variable is set to a single value and doesn't include wildcards or regular expressions as this value will be used by Bitbucket to determine the hostname.

⁠Configuration

It is highly recommended that you use container orchestration software such as Docker Compose⁠ when using this NGINX Host unit as several Docker containers are required for operation. This guide will assume that you are using Docker Compose. Additionally, we will use the official PostgreSQL Docker container⁠ for our database.

To begin, start with a basic docker-compose.yml file as described in the NGINX Host configuration guide⁠. Then, add a service for the database (named db-bitbucket) and the NGINX Host Bitbucket unit (named bitbucket):

bitbucket:
  image: handcraftedbits/nginx-unit-bitbucket
  environment:
    - NGINX_UNIT_HOSTS=mysite.com
    - NGINX_URL_PREFIX=/bitbucket
  links:
    - db-bitbucket
  ports:
    - "7999:7999"
  volumes:
    - data:/opt/container/shared
    - /home/me/bitbucket:/opt/data/bitbucket

db-bitbucket:
  image: postgres
  environment:
    - POSTGRES_USER=user
    - POSTGRES_PASSWORD=password
    - POSTGRES_DB=bitbucket
  volumes:
    /home/me/db-bitbucket:/var/lib/postgresql/data

Observe the following:

• We create a link in bitbucket to db-bitbucket in order to allow Bitbucket to connect to our database.
• We mount /opt/data/bitbucket using the local directory /home/me/bitbucket. This is the directory where Bitbucket stores its data.
• As with any other NGINX Host unit, we mount our data volume, in this case named data, to /opt/container/shared.
• Though not required, we bind the local port 7999 to the bitbucket container's port 7999 in order to expose Git over SSH⁠.

For more information on configuring the PostgreSQL container, consult its documentation⁠.

Finally, we need to create a link in our NGINX Host container to the bitbucket container in order to proxy Bitbucket. Here is our final docker-compose.yml file:

version: "2.1"

volumes:
  data:

services:
  bitbucket:
    image: handcraftedbits/nginx-unit-bitbucket
    environment:
      - NGINX_UNIT_HOSTS=mysite.com
      - NGINX_URL_PREFIX=/bitbucket
    links:
      - db-bitbucket
    ports:
      - "7999:7999"
    volumes:
      - data:/opt/container/shared
      - /home/me/bitbucket:/opt/data/bitbucket

  db-bitbucket:
    image: postgres
    environment:
      - POSTGRES_USER=user
      - POSTGRES_PASSWORD=password
      - POSTGRES_DB=bitbucket
    volumes:
      /home/me/db-bitbucket:/var/lib/postgresql/data

  proxy:
    image: handcraftedbits/nginx-host
    links:
      - bitbucket
    ports:
      - "443:443"
    volumes:
      - data:/opt/container/shared
      - /etc/letsencrypt:/etc/letsencrypt
      - /home/me/dhparam.pem:/etc/ssl/dhparam.pem

This will result in making a Bitbucket instance available at https://mysite.com/bitbucket.

⁠Running the NGINX Host Bitbucket Unit

Assuming you are using Docker Compose, simply run docker-compose up in the same directory as your docker-compose.yml file. Otherwise, you will need to start each container with docker run or a suitable alternative, making sure to add the appropriate environment variables and volume references.

When configuring Bitbucket, be sure to select PostgreSQL as your database, db-bitbucket as the database hostname, and 5432 as the database port if you configured your database according to the previous section.

⁠Environment Variables
