Docker

The official Docker image runs VibeMQ.Server.Host: a standalone broker with configuration from environment variables and an optional config file.

Quick Start 

Build and run (from repository root):

docker build -f docker/Dockerfile -t vibemq .
docker run -p 2925:2925 vibemq

Clients can connect to localhost:2925. By default the broker runs without authentication.

Using Docker Compose 

docker compose -f docker/docker-compose.yml up -d

The broker listens on port 2925. Edit docker/docker-compose.yml to change ports or add environment variables.

Configuration 

The image uses the same options as the rest of VibeMQ (see Configuration). Two mechanisms are supported:

Environment variables — recommended for Docker/Kubernetes. Use the VibeMQ__ prefix and double underscore for nested keys.
Config file — optional JSON file (e.g. appsettings.json). Set VIBEMQ_CONFIG_PATH to the full path of the file; it is loaded first, then env vars override.

Environment variables (examples)

Variable	Description
`VibeMQ__Port`	TCP port (default: 2925)
`VibeMQ__MaxConnections`	Max concurrent connections (default: 1000)
`VibeMQ__MaxMessageSize`	Max message size in bytes (default: 1048576)
`VibeMQ__EnableAuthentication`	`true` or `false`
`VibeMQ__AuthToken`	Legacy token when `EnableAuthentication` is true
`VibeMQ__Authorization__SuperuserUsername`	Superuser login (username/password auth)
`VibeMQ__Authorization__SuperuserPassword`	Superuser password on first run (e.g. from secret)
`VibeMQ__Authorization__DatabasePath`	Path to SQLite auth DB (default: auth.db)
`VibeMQ__StorageType`	`InMemory` or `Sqlite`
`VibeMQ__SqliteStorage__DatabasePath`	Path to SQLite queue DB when `StorageType` is Sqlite
`Logging__LogLevel__Default`	Log level: Debug, Information, Warning, Error

Config file path 

Set VIBEMQ_CONFIG_PATH to load an additional or custom JSON config file (e.g. mounted in the container):

docker run -p 2925:2925 \
  -v /host/path/appsettings.json:/app/config/appsettings.json \
  -e VIBEMQ_CONFIG_PATH=/app/config/appsettings.json \
  vibemq

The built-in appsettings.json in the image provides defaults; env vars override any value from config.

Example: auth and port 

Token-based auth on port 9000:

docker run -p 9000:9000 \
  -e VibeMQ__Port=9000 \
  -e VibeMQ__EnableAuthentication=true \
  -e VibeMQ__AuthToken=your-secret-token \
  vibemq

Username/password auth with persistent auth DB:

docker run -p 2925:2925 \
  -e VibeMQ__EnableAuthentication=true \
  -e VibeMQ__Authorization__SuperuserUsername=admin \
  -e VibeMQ__Authorization__SuperuserPassword=secret \
  -e VibeMQ__Authorization__DatabasePath=/data/auth.db \
  -v vibemq-data:/data \
  vibemq

Example: SQLite persistence 

docker run -p 2925:2925 \
  -e VibeMQ__StorageType=Sqlite \
  -e VibeMQ__SqliteStorage__DatabasePath=/data/vibemq.db \
  -v vibemq-data:/data \
  vibemq

Image details 

Base: mcr.microsoft.com/dotnet/runtime:8.0
Entrypoint: dotnet VibeMQ.Server.Host.dll
Working directory: /app
Exposed port: 2925 (override with VibeMQ__Port and republish)

The host project is VibeMQ.Server.Host in the repository; it uses DI Integration and binds Configuration from the VibeMQ section.
