## docker-compose deployment HertzBeat+Mysql+IoTDB solution

> The docker-compose deployment scheme uses Mysql + IoTDB as the dependent storage service of HertzBeat.  
> This solution will start three container services Mysql, IoTDB, HertzBeat

##### Install Docker & Docker-compose

1. Download and install docker environment & docker-compose environment
   Please refer to [Docker official website documentation](https://docs.docker.com/get-docker/), [Compose installation](https://docs.docker.com/compose/install/)
    ```
    $ docker -v
    Docker version 20.10.12, build e91ed57
    ```

##### docker compose deploys hertzbeat and its dependent services

1. Download the hertzbeat-docker-compose installation deployment script file
   The script file is located in `script/docker-compose/hertzbeat-mysql-iotdb` link [script/docker-compose](https://github.com/apache/hertzbeat/tree/master/script/docker-compose/ hertzbeat-mysql-iotdb)

2. Optional: add external JDBC driver jars to `ext-lib`

   MySQL-compatible monitoring can use the built-in query engine directly, so `mysql-connector-j` is optional.
   If you want HertzBeat to prefer JDBC after restart, place `mysql-connector-j` in `ext-lib`.
   Oracle and DB2 still require external JDBC jars in `ext-lib`.
   
3. Enter the deployment script docker-compose directory, execute

   `docker compose up -d`
