Confluence

Description

Confluence is Atlassian’s enterprise wiki and collaboration platform. This role deploys Confluence via Docker Compose, wires it to PostgreSQL, and integrates proxy awareness, optional OIDC SSO, health checks, and production-friendly defaults for Infinito.Nexus.

Overview

The role builds a minimal custom image on top of the official Confluence image, prepares persistent volumes, and exposes the app behind your reverse proxy. Configuration is driven by variables (image, version, volumes, domains, OIDC). JVM heap sizing follows the container’s mem_limit: JVM_MAXIMUM_MEMORY is 70 % of it and JVM_MINIMUM_MEMORY 35 %.

Cosmos

The diagram places Confluence in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role’s deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Features

  • Fully Dockerized: Compose stack with a dedicated data volume (confluence_data) and a slim overlay image for future add-ons.

  • Reverse-Proxy Ready: Sets ATL_PROXY_NAME/PORT/SCHEME/SECURE so Confluence generates correct external URLs behind HTTPS.

  • OIDC SSO (Optional): Pre-templated vars for issuer, client, scopes, JWKS; compatible with Atlassian DC SSO/OIDC marketplace apps.

  • Central Database: PostgreSQL integration (local or central DB) with bootstrap credentials from role vars.

  • JVM Auto-Tuning: JVM_MINIMUM_MEMORY / JVM_MAXIMUM_MEMORY are 35 % and 70 % of the service mem_limit.

  • Health Checks: Curl-based container healthcheck for early failure detection.

  • CSP & Canonical Domains: Hooks into platform CSP/SSL/domain management to keep policies strict and URLs stable.

  • Backup Friendly: Data isolated under {{ CONFLUENCE_HOME }}.

Quick Setup

Development

Clone, set up the workstation, and deploy Confluence onto the local stack:

git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=web-app-confluence full_cycle=false

Production

Run the published image to provision the inventory and deploy Confluence to a managed server (the mounted volume persists the inventory):

APP=web-app-confluence
HOST=<your-server>
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"

docker run --rm -it \
  -v "$PWD/inventories:/etc/infinito.nexus/inventories" \
  -e APP="$APP" -e HOST="$HOST" -e DOMAIN="$DOMAIN" -e TLS_MODE="$TLS_MODE" -e SSH_PUBLIC_KEY="$SSH_PUBLIC_KEY" \
  ghcr.io/infinito-nexus/core/debian bash -c '
    INVENTORY=/etc/infinito.nexus/inventories/production
    infinito administration inventory provision "$INVENTORY" \
      --inventory-file "$INVENTORY/devices.yml" \
      --host "$HOST" \
      --include "$APP" \
      --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}" &&
    infinito administration deploy dedicated "$INVENTORY/devices.yml" \
      --password-file "$INVENTORY/.password" \
      --diff -vv'

Further Resources

Persona contract opt-outs

meta/services.yml pins sso.enabled to false and tasks/main.yml provisions no Confluence account — account creation belongs to the licensed first-run setup wizard. Neither the biber nor the administrator persona has credentials to sign in with, so templates/playwright.env.j2 declares PERSONA_BIBER_BLOCKED=true and PERSONA_ADMINISTRATOR_BLOCKED=true. The guest persona and the baseline reachability assertions run unconditionally.
