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:

[global]
config_backend = db

external vars

See sources below

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.
This is for environment priview (minimal setup)
