## About
**Diun** :bell: is a CLI application written in [Go](https://golang.org/) to receive notifications :inbox_tray: when a Docker :whale: image is updated on a Docker registry. With Go, this app can be used across many platforms :game_die: and architectures. This support includes Linux, FreeBSD, macOS and Windows on architectures like amd64, i386, ARM and others.

# Docker provider
* [About](#about)
* [Quick start](#quick-start)
* [Configuration](#configuration)
## About
The Docker provider allows you to analyze the containers of your standalone Docker instance defined in the [Diun configuration](../configuration.md) to extract the images found and check for updates on the registry.
## Quick start
In this section we quickly go over a basic docker-compose file using your local docker provider.
First of all, let's create a Diun configuration we named `diun.yml`:
```yml
watch:
workers: 20
schedule: "*/30 * * * *"
providers:
docker:
mydocker:
watch_stopped: true
```
Here we use a single Docker provider with a minimum configuration to analyze labeled containers (watch by default disabled), even stopped ones, of your local Docker instance.
Now let's create a simple docker-compose file with Diun and some simple services:
```yml
version: "3.5"
services:
diun:
image: crazymax/diun:latest
volumes:
- "./data:/data"
- "./diun.yml:/diun.yml:ro"
- "/var/run/docker.sock:/var/run/docker.sock"
environment:
- "TZ=Europe/Paris"
- "LOG_LEVEL=info"
- "LOG_JSON=false"
restart: always
cloudflared:
image: crazymax/cloudflared:latest
ports:
- target: 5053
published: 5053
protocol: udp
- target: 49312
published: 49312
protocol: tcp
environment:
- "TZ=Europe/Paris"
- "TUNNEL_DNS_UPSTREAM=https://1.1.1.1/dns-query,https://1.0.0.1/dns-query"
labels:
- "diun.enable=true"
- "diun.watch_repo=true"
restart: always
```
As an example we use [crazymax/cloudflared:latest](https://github.com/crazy-max/docker-cloudflared) Docker image. A few [labels](#configuration) are added to configure the image analysis of this container for Diun. Now start this composition with `docker-composes up -d` and take a look at the logs:
```
$ docker-compose logs -f

```
## Configuration
In the same spirit as the [static provider](static.md), you can configure more finely the way to analyze the image of your container. But unlike the static provider, this is done via Docker labels:
* `diun.enable`: Set to true to enable image analysis of this container. Required if `watch_by_default` is disabled for this provider.
* `diun.os`: OS to use. _Optional_. (default: `linux`).
* `diun.arch`: Architecture to use. _Optional_. (default: `amd64`).
* `diun.regopts_id`: Registry options ID from [`regopts`](../configuration.md#regopts) to use.
* `diun.watch_repo`: Watch all tags of this container image (default: `false`).
* `diun.max_tags`: Maximum number of tags to watch if `diun.watch_repo` enabled. 0 means all of them (default: `0`).
* `diun.include_tags`: Semi-colon separated list of regular expressions to include tags. Can be useful if you enable `diun.watch_repo`.
* `diun.exclude_tags`: Semi-colon separated list of regular expressions to exclude tags. Can be useful if you enable `diun.watch_repo`.

# Static provider
* [About](#about)
* [Quick start](#quick-start)
## About
The static provider is the most basic way to analyse Docker images. Nothing special to see here as everything is configured through the [providers field](../configuration.md#providers).
## Quick start
But let's take a look with a simple example:
```yml
db:
path: diun.db
watch:
workers: 20
schedule: "* * * * *"
regopts:
jfrog:
username: foo
password: bar
providers:
static:
- name: crazymax/cloudflared
watch_repo: true
- name: docker.bintray.io/jfrog/xray-mongo:3.2.6
regopts_id: jfrog
```
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:
```

# Swarm provider
* [About](#about)
* [Quick start](#quick-start)
* [Configuration](#configuration)
## About
The Swarm provider is closely linked to the [Docker provider](docker.md) except that it allows you to analyze the services of your Swarm cluster defined in the [Diun configuration](../configuration.md) to extract the images found and check for updates on the registry.
## Quick start
In this section we quickly go over a basic stack using your local swarm cluster.
First of all, let's create a Diun configuration we named `diun.yml`:
```yml
watch:
workers: 20
schedule: "*/30 * * * *"
providers:
swarm:
myswarm:
```
Here we use a single Swarm provider with a minimum configuration to analyze labeled containers (watch by default disabled), of your local Swarm cluster.
Now let's create a simple stack for Diun:
```yml
version: "3.5"
services:
diun:
image: crazymax/diun:latest
volumes:
- "./data:/data"
- "./diun.yml:/diun.yml:ro"
- "/var/run/docker.sock:/var/run/docker.sock"
environment:
- "TZ=Europe/Paris"
- "LOG_LEVEL=info"
- "LOG_JSON=false"
deploy:
placement:
constraints:
- node.role == manager
```
And another one with a simple service:
```yml
version: "3.5"
services:
nginx:
image: nginx
ports:
- target: 80
published: 80
protocol: udp
deploy:
mode: replicated
replicas: 2
labels:
- "diun.enable=true"
- "diun.watch_repo=true"
```
As an example we use [nginx](https://hub.docker.com/_/nginx/) Docker image. A few [labels](#configuration) are added to configure the image analysis of this service for Diun. We can now start these 2 stacks:
```
docker stack deploy -c diun.yml diun
docker stack deploy -c nginx.yml nginx
```
And watch logs of Diun service:
```
$ docker service logs -f diun_diun
