Deploy with Docker Compose

Set up a three-node cluster with Docker Compose and enrolment tokens.

Set up a three-node cluster with Docker Compose. It is meant for test environments; in production, each node goes on its own machine.

Requirements

Docker with Compose.
The viuzi/teseladb:latest image, which always carries the newest release in Download.

Write the file

Save this file as compose.yaml in an empty directory on the machine where you will start the nodes:

YAML

services:
  node-01:
    image: viuzi/teseladb:latest
    command: start --dbpath /data --bind_ip 0.0.0.0 --peer-listen 0.0.0.0:27100 --admin-listen 0.0.0.0:27200
    volumes: ["node-01:/data"]
    ports: ["27017:27017"]
  node-02:
    image: viuzi/teseladb:latest
    command: >
      start --dbpath /data --bind_ip 0.0.0.0 --peer-listen 0.0.0.0:27100 --admin-listen 0.0.0.0:27200
      --join node-01:27100 --enroll-token ${TOKEN_02}
    volumes: ["node-02:/data"]
  node-03:
    image: viuzi/teseladb:latest
    command: >
      start --dbpath /data --bind_ip 0.0.0.0 --peer-listen 0.0.0.0:27100 --admin-listen 0.0.0.0:27200
      --join node-01:27100 --enroll-token ${TOKEN_03}
    volumes: ["node-03:/data"]
volumes:
  node-01:
  node-02:
  node-03:

Start the first node and create the tokens

Shell

docker compose up -d node-01
export TOKEN_02=$(docker compose exec node-01 teseladb admin --dbpath /data token create --ttl 1h)
export TOKEN_03=$(docker compose exec node-01 teseladb admin --dbpath /data token create --ttl 1h)

Start the other two

Shell

docker compose up -d node-02 node-03

Check

Once the three containers are running, docker compose exec node-01 teseladb admin --dbpath /data nodes lists the three nodes as active.

Common problems

A node does not join because its token expired or was already used. Create another and start that service again.
