Updtr

Drop-in replacement of Watchtower for manual updating.

Why?

I prefer to review pending updates once in a while and read changelog before, so I would be shure nothing will be broken or, at least, will know how to fix it.

Quick Start

Run the updtr container with the following command:

docker run -d --name updtr -v /var/run/docker.sock:/var/run/docker.sock shemanaev/updtr

or with docker-compose:

services:
  updtr:
    image: shemanaev/updtr
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime:ro
    ports:
      - 8080:8080
    restart: unless-stopped

Mappings

It describes the way to find changelog by image name. Feel free to propose new mappings into this file.

# version of mappings file
version: 1
images:
  -
    # array of image names
    # can be with tag or without
    # tagged names has higher priority
    names: [shemanaev/updtr]
    # url to changelog
    url: https://github.com/shemanaev/updtr
    # possilble values:
    # Plaintext
    # Markdown
    # Asciidoc
    # Html
    # Github - notes of latest release, url must point to github repo
    type: Github

Additional mappings can be loaded from file: /data/mapping.yml

docker run -d --name updtr -v ${PWD}/mapping.yml:/data/mapping.yml -v /var/run/docker.sock:/var/run/docker.sock shemanaev/updtr

It takes higher priority than built-in.
