File provider

About

The file provider lets you define Docker images to analyze through a YAML file or a directory.

Example

db:
  path: diun.db

watch:
  workers: 20
  schedule: "0 */6 * * *"

regopts:
  - name: "myregistry"
    username: fii
    password: bor
    timeout: 5s
  - name: "docker.io/crazymax"
    selector: image
    username: fii
    password: bor
  - name: "docker.io"
    selector: image
    username: foo
    password: bar

providers:
  file:
    filename: /path/to/config.yml

### /path/to/config.yml

# Watch latest tag of crazymax/nextcloud image on docker.io (DockerHub)
# with registry options named 'docker.io/crazymax' (image selector).
- name: docker.io/crazymax/nextcloud:latest

# Watch 4.0.0 tag of jfrog/artifactory-oss image on frog-docker-reg2.bintray.io (Bintray)
# with registry options named 'myregistry' (name selector).
- name: jfrog-docker-reg2.bintray.io/jfrog/artifactory-oss:4.0.0
  regopt: myregistry

# Watch coreos/hyperkube image on quay.io (Quay) and assume latest tag.
- name: quay.io/coreos/hyperkube

# Watch crazymax/swarm-cronjob image and assume docker.io registry and latest tag
# with registry options named 'docker.io/crazymax' (image selector).
# Only include tags matching regexp ^1\.2\..*
- name: crazymax/swarm-cronjob
  watch_repo: true
  include_tags:
    - ^1\.2\..*

# Watch portainer/portainer image on docker.io (DockerHub) and assume latest tag
# with registry options named 'docker.io' (image selector).
# Only watch latest 10 tags and include tags matching regexp ^\d+\.\d+\..*
- name: docker.io/portainer/portainer
  watch_repo: true
  max_tags: 10
  include_tags:
    - ^\d+\.\d+\..*

# Watch alpine image (library) and assume docker.io registry and latest tag
# with registry options named 'docker.io' (image selector).
# Force linux/arm64/v8 platform for this image
- name: alpine
  watch_repo: true
  platform:
    os: linux
    arch: arm64
    variant: v8

Quick start

Let's take a look with a simple example:

db:
  path: diun.db

watch:
  workers: 20
  schedule: "0 */6 * * *"

regopts:
  - name: "docker.bintray.io"
    selector: image
    username: foo
    password: bar

providers:
  file:
    filename: /path/to/config.yml

# /path/to/config.yml
- name: crazymax/cloudflared
  watch_repo: true
- name: docker.bintray.io/jfrog/xray-mongo:3.2.6

Here we want to analyze all tags of crazymax/cloudflared and docker.bintray.io/jfrog/xray-mongo:3.2.6 tag. Now let's start Diun:

$ diun serve --config diun.yml

Configuration

`filename`

Defines the path to the configuration file.

!!! warning filename and directory are mutually exclusive

!!! example "File" yaml providers: file: filename: /path/to/config/conf.yml

!!! abstract "Environment variables" * DIUN_PROVIDERS_FILE_FILENAME

`directory`

Defines the path to the directory that contains the configuration files (*.yml or *.yaml).

!!! warning filename and directory are mutually exclusive

!!! example "File" yaml providers: file: directory: /path/to/config

!!! abstract "Environment variables" * DIUN_PROVIDERS_FILE_DIRECTORY

YAML configuration file

The configuration file(s) defines a slice of images to analyze with the following fields:

Name	Default	Description
`name`	`latest`	Docker image name to watch using `registry/path:tag` format. If registry omitted, `docker.io` will be used and if tag omitted, `latest` will be used
`regopt`		Registry options name to use
`watch_repo`	`false`	Watch all tags of this image (be careful with this setting)
`max_tags`	`0`	Maximum number of tags to watch if `watch_repo` enabled. `0` means all of them
`include_tags`		List of regular expressions to include tags. Can be useful if you enable `watch_repo`
`exclude_tags`		List of regular expressions to exclude tags. Can be useful if you enable `watch_repo`
`platform.os`	automatic	Operating system to use as custom platform
`platform.arch`	automatic	CPU architecture to use as custom platform
`platform.variant`	automatic	Variant of the CPU to use as custom platform
