+# Installing Icinga DB in Containers
+
+This image integrates Icinga DB into your containerized environment.
+
+## Usage
+
+```bash
+docker network create icinga
+
+docker run --rm -d \
+	--network icinga \
+	--name redis-icingadb \
+	redis
+
+docker run -d \
+	--network icinga \
+	--name mariadb-icingadb \
+	-e MYSQL_RANDOM_ROOT_PASSWORD=1 \
+	-e MYSQL_DATABASE=icingadb \
+	-e MYSQL_USER=icingadb \
+	-e MYSQL_PASSWORD=123456 \
+	mariadb
+
+docker run -d \
+	--network icinga \
+	--restart always \
+	--name icingadb \
+	-e ICINGADB_REDIS_HOST=redis-icingadb \
+	-e ICINGADB_REDIS_PORT=6379 \
+	-e ICINGADB_REDIS_PASSWORD=123456 \
+	-e ICINGADB_DATABASE_HOST=mariadb-icingadb \
+	-e ICINGADB_DATABASE_PORT=3306 \
+	-e ICINGADB_DATABASE_DATABASE=icingadb \
+	-e ICINGADB_DATABASE_USER=icingadb \
+	-e ICINGADB_DATABASE_PASSWORD=123456 \
+	icinga/icingadb
+```
+
+The container doesn't need any volumes and takes the environment variables.
+
+### Environment Variables
+
+The environment variables consists of the key `ICINGADB_DATABASE_` and the configuration option name like `HOST` in uppercase.
+
+```
+ICINGADB_DATABASE_HOST=mariadb-icingadb
+```
+
+For more options, see the [Icinga DB configuration documentation].
+
+### Connect via TLS
+
+```bash
+docker run -d \
+	--network icinga \
+	--restart always \
+	--name icingadb \
+	-e ICINGADB_REDIS_HOST=redis-icingadb \
+	-e ICINGADB_REDIS_PORT=6379 \
+	-e ICINGADB_REDIS_PASSWORD=123456 \
+	-e ICINGADB_REDIS_TLS=true \
+	-e ICINGADB_REDIS_CERT='[PEM-encoded content or path to a file (in a volume)]' \
+	-e ICINGADB_REDIS_KEY='[PEM-encoded content or path to a file (in a volume)]' \
+	-e ICINGADB_REDIS_CA='[PEM-encoded content or path to a file (in a volume)]' \
+	-e ICINGADB_DATABASE_HOST=mariadb-icingadb \
+	-e ICINGADB_DATABASE_PORT=3306 \
+	-e ICINGADB_DATABASE_DATABASE=icingadb \
+	-e ICINGADB_DATABASE_USER=icingadb \
+	-e ICINGADB_DATABASE_PASSWORD=123456 \
+	-e ICINGADB_DATABASE_TLS=true \
+	-e ICINGADB_DATABASE_CERT='[PEM-encoded content or path to a file (in a volume)]' \
+	-e ICINGADB_DATABASE_KEY='[PEM-encoded content or path to a file (in a volume)]' \
+	-e ICINGADB_DATABASE_CA='[PEM-encoded content or path to a file (in a volume)]' \
+	icinga/icingadb
+```
+
+## Build it yourself
+
+```bash
+git clone https://github.com/Icinga/icingadb.git
+
+docker build -t icingadb --file Containerfile .
+```
