# Docker IcingaWeb2
[![Build Status](https://git.ao-it.net/docker/icingaweb2/actions/workflows/docker-build.yml/badge.svg?branch=main&event=push)](https://git.ao-it.net/docker/icingaweb2/actions?workflow=docker-build.yml&actor=0&status=0)
If you need a full stack:
* [AO-IT: icinga-stack](https://git.ao-it.net/docker/icinga-stack)
* [AO-IT: icinga2](https://git.ao-it.net/docker/icinga2)
Or a additional satellite:
* [AO-IT: icinga-satellite](https://git.ao-it.net/docker/icinga-satellite)
## usage
If you have a functional icinga2 instance only without icingaweb2:
```bash
git clone https://git.ao-it.net/docker/icingaweb2
cd icingaweb2
cp env.sample .env
# must edit: GRAFANA_HOST with local IP or FQDN
nano .env # edit your env
docker compose up -d
```
Hints:
* If you run the setup without any environment vars the setup token will be printet in docker log!
* If you deploy IcingaDB ENV but it can't be reach, icingaweb looks like broken but it isn't
* You can remove the environment var `ICINGAWEB2_CONF_ONCE` whan will changes in `compose.yml` environment deploy every time if the container starts.
* You can use this for future config changes, but this isn't good tested and i am not sure i will recommend this...
## understand environment
For the configuration (primarily the initial setup) I use a similar method as: https://hub.docker.com/r/icinga/icingaweb2
* In my case a prefix like `ICINGAWEB2_CONF` refers a configuration file.
* As a separator I not (longer) use `.` rather `__` (2x `_`)
* After the first `__` it follows the `Section` from this ini file.
* After the second `__` it follows the `Key` from this `Section` before.
* And after the `=` is comes the `value`.
So will this:
```
ICINGAWEB2_CONF__global__config_backend=db
```
create this:
```ini
[global]
config_backend = db
```

### static vars
var | description

ICINGAWEB2_CONF_ONCE | if var exists: all configuration setups (above) run only on fist setup.
ICINGAWEB2_DB_RESOURCE_NAME | needed for setup script to know witch database is used for users
ICINGAWEB2_DEFAULT_ADMIN_USER | default admin username addidional this var is primary identifier to run auto config
ICINGAWEB2_DEFAULT_ADMIN_PASS | default admin password
### easy setup
If you use the example, than you can setup the `env.sample`.
All required variables are included and insert the values ​​in the correct places.
Hint: in this file all vars dont have the `2` behind icingaweb2 or icinga2.
Vars for the container have the `2`
## example
See [compose.yml](compose.yml).
This is for environment priview (minimal setup)
```yaml
