handcraftedbits/nginx-unit-confluence repository overview

⁠NGINX Host Confluence Unit

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

⁠Features

• Atlassian Confluence 6.1.0
• NGINX Host SSL certificates are automatically imported into Confluence's JVM so Atlassian application links can easily be created

⁠Support Notes

This container uses OpenJDK⁠ for its JVM and as such this unit is considered an unsupported platform by Atlassian.

⁠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 Confluence 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-confluence) and the NGINX Host Confluence unit (named confluence):

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

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

Observe the following:

• We create a link in confluence to db-confluence in order to allow Confluence to connect to our database.
• We mount /opt/data/confluence using the local directory /home/me/confluence. This is the directory where Confluence stores its data.
• As with any other NGINX Host unit, we mount our data volume, in this case named data, to /opt/container/shared.

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 confluence container in order to proxy Confluence. Here is our final docker-compose.yml file:

version: "2.1"

volumes:
  data:

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

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

  proxy:
    image: handcraftedbits/nginx-host
    links:
      - confluence
    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 Confluence instance available at https://mysite.com/confluence.

⁠Running the NGINX Host Confluence 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 Confluence, be sure to select PostgreSQL as your database, db-confluence as the database hostname, and 5432 as the database port if you configured your database according to the previous section.
