mattdavis90/docker-keeper repository overview

⁠docker-keeper

docker-keeper is designed to keep you docker-swarm updates with the latest images from you CI pipeline.

It can be deployed as simply as

version: "3.7"

services:
  keeper:
  image: registry.abitof.space/docker-keeper:latest
  environment:
    - KEEPER_SECRET_KEY=YourSecretKeyGoesHere
  placement:
    constraints:
      - "node.role == manager"
volumes:
  - /var/run/docker.sock:/var/run/docker.sock

This will start a docker-keeper server listening on port 8000 by default

You should then label other services with "keeper.id". This ID is then used to target this service from the API. For example;

services:
  nginx:
    image: my-registry/nginx:0.1.0
    deploy:
      labels:
        keeper.id: "my-nginx"

The following environmental variables can be used to override functionality

GET to KEEPER_ROOT will list all services managed by docker-keeper. POST to KEEPER_ROOT with the following payload will update the given service.

{
  "secretkey": "YourSecretKeyGoesHere",
  "id: "my-nginx",
  "image": "my-registry/nginx:0.2.0"
}
