Setting up vector via accessories

[morgoth]

Setting up vector via accessories can be done like this:

accessories:
  vector:
    image: timberio/vector:0.35.0-debian
    cmd:
    hosts:
      - <host-1-ip>
      - <host-2-ip>
    port: "8686:8686"
    volumes:
      - /root/vector.yaml:/etc/vector/vector.yaml:ro
      - /var/run/docker.sock:/var/run/docker.sock

where one have to setup /root/vector.yaml on the root host.

My usecase was to integrate https://betterstack.com/ and the config for it (after registering and setting up account) can be fetched via curl https://logs.betterstack.com/vector-yaml/docker/<VECTOR_TOKEN> -o /root/vector.yaml

Simplified setup of vector service:

accessories:
  vector:
    image: timberio/vector:0.37.1-alpine
    hosts:
      - <host-1-ip>
      - <host-2-ip>
    env:
      secret:
        - VECTOR_TOKEN
    port: "8686:8686"
    files:
      - config/vector.yaml:/etc/vector/vector.yaml:ro
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

This way you can keep config/vector.yaml file locally in repo and have full control over it. The VECTOR_TOKEN is passed as secret env variable.

How much is your monthly usage with this setup on betterstack end?

It varies based on the app load. There is a free plan which you can use to try it out and see on your app.
