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 ...

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.
• 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

static vars

var	description
ICINGAWEB2_CONF_ONCE	if true: all configuration setups (above) run only on fist setup.
ICINGAWEB2_DB_RESOURCE_NAME	needed for setup scrip to know witch database is used for users
ICINGAWEB2_DEFAULT_ADMIN_USER	default admin username
ICINGAWEB2_DEFAULT_ADMIN_PASS	default admin password

easy setup

If you use the example, than you kan 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 icinga. Vars for the container have the 2

example

See compose.yml.

If you ask why the hell vars with . :

• Underscores a bad for splitting in case of icingaweb2. Some options need them
• https://stackoverflow.com/questions/2821043/allowed-characters-in-linux-environment-variable-names
• no better idea to handle this for setup script

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.
