Diun v3 to v4

Timeout value as duration

Only accept duration as timeout value (10 becomes 10s)

Registry options enhancements

Configuration of registry options has changed:

v3 
regopts:
  myregistry:
    username: fii
    password: bor
    insecure_tls: true
    timeout: 5s
  docker.io:
    username: foo
    password: bar
  docker.io/crazymax:
    username_file: /run/secrets/username
    password_file: /run/secrets/password
v4 
regopts:
  - name: "myregistry"
    username: fii
    password: bor
    insecureTLS: true
    timeout: 5s
  - name: "docker.io"
    selector: image
    username: foo
    password: bar
  - name: "docker.io/crazymax"
    selector: image
    usernameFile: /run/secrets/username
    passwordFile: /run/secrets/password

Also, registry options can now be resolved automatically based on image name. Take a look at the Registry options configuration for more details.

Configuration transposed into environment variables

All configuration is now transposed into environment variables. Take a look at the documentation for more details.

DIUN_DB env var has been renamed DIUN_DB_PATH to follow environment variables transposition.

All fields in configuration are now camelCased

In order to enable transposition into environmental variables, all fields in configuration are now camelCased:

  • notif.mail.insecure_skip_verify > notif.mail.insecureSkipVerify
  • notif.rocketchat.user_id > notif.rocketchat.userID
  • watch.first_check_notif > watch.firstCheckNotif
  • ...

/diun.yml not loaded by default in Docker image

Following the transposition of the configuration into environment variables, the configuration file /diun.yml is no longer loaded by default in the official Docker image.

If you want to load a configuration file through the Docker image you will have to declare the CONFIG environment variable with serve command pointing to the assigned configuration file:

Tip

This is no longer required since version 4.2.0. Now configuration file can be loaded from default places

version: "3.5"

services:
  diun:
    image: crazymax/diun:latest
    container_name: diun
    command: serve
    volumes:
      - "./data:/data"
      - "./diun.yml:/diun.yml:ro"

    environment:
      - "CONFIG=/diun.yml"
