If you are new to running umh-core with Docker Compose, read [Setup](/production/deployment/docker-compose/setup.md) first. [TimescaleDB](https://www.timescale.com/) is PostgreSQL with an extension optimized for time-series data. Manufacturing data is inherently time-series: sensor readings, production counts, and machine states all have timestamps. PgBouncer is a connection pooler for TimescaleDB. umh-core bridges can create many simultaneous connections to the database, and PostgreSQL handles a limited number of them (typically 100 by default), so without pooling a busy system exhausts the limit and connections start failing. Applications connect to PgBouncer on port 5432 and PgBouncer connects to TimescaleDB internally. ## Complete docker-compose.yaml umh-core with TimescaleDB and PgBouncer. Copy this into `docker-compose.yaml` and fill in the fields marked `TODO`. > **IMPORTANT**: Change the template's database credentials before using this in production! ```yaml services: umh: # TODO: set your desired container version here # e.g. `umh-core:v0.44.31` image: management.umh.app/oci/united-manufacturing-hub/umh-core:ENTER_VERSION_HERE restart: unless-stopped volumes: - umh-data:/data environment: # TODO: Enter your instance's Auth Token. # You'll find it in your instance's configuration # file on management.umh.app. - AUTH_TOKEN=your_auth_token # TODO: Change the LOCATION_0 parameter # to your desired Level 0 Location name - LOCATION_0=your_level_0_location # Optional: Define more levels # - LOCATION_1=your_level_1 # - LOCATION_2=your_level_2 # - LOCATION_3=your_level_3 # - LOCATION_4=your_level_4 - RELEASE_CHANNEL=stable - API_URL=https://management.umh.app/api timescaledb: image: management.umh.app/oci/timescale/timescaledb:2.24.0-pg17 restart: unless-stopped environment: - POSTGRES_DB=umh # TODO: Set your postgresDB Password and Username here - POSTGRES_USER=postgres - POSTGRES_PASSWORD=postgres volumes: - timescaledb-data:/var/lib/postgresql/data healthcheck: test: ["CMD-SHELL", "pg_isready -h timescaledb"] interval: 10s timeout: 5s retries: 5 networks: - timescaledb-network pgbouncer: image: management.umh.app/oci/edoburu/pgbouncer:v1.24.1-p1 restart: unless-stopped environment: - DB_NAME=umh # This has to be the same value as # timescaledb.environment.POSTGRES_USER - DB_USER=postgres # This has to be the same value as # timescaledb.environment.POSTGRES_PASSWORD - DB_PASSWORD=postgres - DB_HOST=timescaledb - AUTH_TYPE=scram-sha-256 ports: - 5432:5432 healthcheck: test: ["CMD-SHELL", "pg_isready -h pgbouncer"] interval: 10s timeout: 5s retries: 5 depends_on: timescaledb: condition: service_healthy networks: - default - timescaledb-network networks: default: timescaledb-network: internal: true volumes: umh-data: {} timescaledb-data: {} ``` To start the stack, see [Starting the Stack](/production/deployment/docker-compose/setup.md#starting-the-stack). ## Already running umh-core? Add the following to the `docker-compose.yaml` you already have. Your existing `umh:` service stays as it is. **1. Two new services inside `services:`** ```yaml timescaledb: image: management.umh.app/oci/timescale/timescaledb:2.24.0-pg17 restart: unless-stopped environment: - POSTGRES_DB=umh # TODO: Set your postgresDB Password and Username here - POSTGRES_USER=postgres - POSTGRES_PASSWORD=postgres volumes: - timescaledb-data:/var/lib/postgresql/data healthcheck: test: ["CMD-SHELL", "pg_isready -h timescaledb"] interval: 10s timeout: 5s retries: 5 networks: - timescaledb-network pgbouncer: image: management.umh.app/oci/edoburu/pgbouncer:v1.24.1-p1 restart: unless-stopped environment: - DB_NAME=umh # This has to be the same value as # timescaledb.environment.POSTGRES_USER - DB_USER=postgres # This has to be the same value as # timescaledb.environment.POSTGRES_PASSWORD - DB_PASSWORD=postgres - DB_HOST=timescaledb - AUTH_TYPE=scram-sha-256 ports: - 5432:5432 healthcheck: test: ["CMD-SHELL", "pg_isready -h pgbouncer"] interval: 10s timeout: 5s retries: 5 depends_on: timescaledb: condition: service_healthy networks: - default - timescaledb-network ``` **2. A new top-level `networks:` section** ```yaml networks: default: timescaledb-network: internal: true ``` **3. One more entry under `volumes:`** ```yaml timescaledb-data: {} ``` **4. Apply the changes** ```bash docker compose up -d ``` See [Starting the Stack](/production/deployment/docker-compose/setup.md#starting-the-stack) for the other compose commands. ## What this declares * 2 Services called `pgbouncer` and `timescaledb`: PgBouncer acts as a proxy to TimescaleDB. This means the Credentials have to match between these two Services. The `depends_on` entry with `condition: service_healthy` on `pgbouncer` enforces the startup order; the Healthchecks only report whether a Service is healthy. `timescaledb` is isolated in the Network `timescaledb-network`. `pgbouncer` is both in the `default` and the `timescaledb-network`. This makes PgBouncer the only Service which can talk to TimescaleDB directly. * 2 Networks called `timescaledb-network` and `default`: Without the Network section the Network `default` is always created by default. Services use the Network `default` if no explicit Network configuration is provided. The `timescaledb-network` is configured to be internal which means Services can't reach the internet or any Service outside this Network if they are only connected through this Network. * 1 Volume called `timescaledb-data`: This is where TimescaleDB stores its data. Once the stack is running, PostgreSQL is reachable through PgBouncer at `localhost:5432`. A database on its own has nothing to show you. Most deployments add [Grafana](/production/deployment/docker-compose/additional-services/grafana.md) on top of it, which is why both are part of the [**Recommended UMH Stack**](/production/deployment/docker-compose/additional-services/recommended-umh-stack.md). --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.umh.app/production/deployment/docker-compose/additional-services/timescaledb.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
