Docker Swarm

This section provides information on installing SigNoz on Docker Swarm.

Prerequisites

• A Linux or macOS machine. Microsoft Windows is not officially supported.
• Docker Engine. A minimum of 4GB of memory must be allocated to each Docker node.
• Docker Compose
• Git client

Install SigNoz on Docker Swarm

1. In a directory of your choosing, clone the SigNoz repository and 'cd' into the signoz/deploy directory by entering the following commands:

   git clone -b main https://github.com/SigNoz/signoz.git && cd signoz/deploy/
   

2. Initialize a single-node swarm by entering the following command:

   docker swarm init
   

   The output should look similar as shown below:

   Swarm initialized: current node (6muco3j7jjuo6k4rbiq8yr8fw) is now a manager.
   
   To add a worker to this swarm, run the following command:
   
   docker swarm join --token SWMTKN-1-6ak6diq1lbrwemx17up9c1ph039h64z0dxksjxv647qnqrd290-4tt6q22dd462p4lf2n6bqbnt4 192.168.65.3:2377
   
   To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
   

3. (Optional) You can use the docker swarm join command to add more nodes to the swarm. Note that the node you added in the previous step is the manager. For details, see the Docker Swarm Join page of the Docker documentation.

4. Deploy SigNoz by entering the docker stack deploy command and specifying the following:

   • -c and the path to the Compose file (docker-swarm/clickhouse-setup/docker-compose.yaml)
   • The name of the stack (signoz)

   docker stack deploy -c docker-swarm/clickhouse-setup/docker-compose.yaml signoz
   

   The output should look similar to the following:

   Creating network signoz_default
   Creating service signoz_query-service
   Creating service signoz_frontend
   Creating service signoz_otel-collector
   Creating service signoz_hotrod
   Creating service signoz_load-hotrod
   Creating service signoz_clickhouse
   Creating service signoz_alertmanager
   

5. (Optional) By default, the instructions in this document create three replicas, and each replica can handle 50K spans per second. To handle an increased load, perform the steps in the Scale Up section of the Operate on Docker Swarm page.

Verify the Installation

1. Using the docker stack services command, monitor the SigNoz deployment process. Wait until all SigNoz services and replicas are created:

   docker stack services signoz
   

   You should see the following output:

   ID             NAME                            MODE         REPLICAS   IMAGE                                          PORTS

   hw28zb1hozu5   signoz_query-service            replicated   1/1        signoz/query-service:0.8.0                     *:8080->8080/tcp
