Service Dependency Graph

Updated: 2026-01-21

This document maps dependencies between BeeCompose services and their backing stores.

Service Dependency Chains

Standalone Services (No Dependencies)

These services have no internal service dependencies:

  • bitwarden
  • dependency-track
  • duckling
  • minio
  • nexus
  • phpmyadmin (requires external MySQL)
  • shields
  • traefik
  • tus

Simple Dependencies (Single Database)

Services with a single database dependency:

Service Depends On
confluence PostgreSQL
crowd PostgreSQL
directus MySQL
huginn PostgreSQL
jira PostgreSQL
keycloak PostgreSQL
metabase PostgreSQL
monica MySQL
registry (htpasswd auth only)
sonarqube PostgreSQL
statping PostgreSQL

Network Dependencies

External Network: traefik_default

All services except the following connect to the external traefik_default network:

Service Network Configuration
traefik Creates traefik_default (owns it)
mysql Internal only
openvpn Internal only

Internal Networks

Each service with multiple containers uses an internal network:

Service Internal Network
cabot cabot
confluence confluence
crowd crowd
directus directus
gitlab gitlab
graylog graylog
huginn huginn
jira jira
keycloak keycloak
metabase metabase
monica monica
mysql mysql
openvpn openvpn
redash redash
rundeck rundeck
sentry sentry
shields shields
sonarqube sonarqube
statping statping
weblate weblate
zabbix zabbix

Initialization Order

When deploying multiple services, use this order:

  1. traefik - Required by all HTTP services
  2. Standalone services - No dependencies
  3. Database services - If shared databases are used
  4. Application services - Depend on databases

Cross-Service Dependencies

Some services can share databases (not default configuration):

Shared Database Potential Consumers
External PostgreSQL gitlab, sentry, keycloak, metabase
External MySQL directus, monica, zabbix
External Redis gitlab, sentry, redash

To enable shared databases, modify environment variables to point to external hosts.
