Docker IcingaWeb2

Designed with https://git.ao-it.net/docker/icinga2

quick start

If you have a functional icinga2 instance only without icingaweb2:

git clone https://git.ao-it.net/docker/icingaweb2
cd icingaweb2 
cp env.sample .env
nano .env     # edit your settings
docker compose up -d

For a full deployment see: comming soon ...

If you run the setup without any environment vars the setup token will be printet in docker log!

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

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 tested and i am not sure i will recommend this...
For now be save and use it only for inital setup.
