## What is DolphinScheduler?
|
||||
|
||||
Dolphin Scheduler is a distributed and easy-to-expand visual DAG workflow scheduling system, dedicated to solving the complex dependencies in data processing, making the scheduling system out of the box for data processing.

### How to stop dolphinscheduler by docker-compose?
|
||||
|
||||
Stop containers:
|
||||
|
||||
```
|
||||
docker-compose stop
|
||||
```
|
||||
|
||||
Stop containers and removes containers, networks and volumes:
|
||||
|
||||
```
|
||||
docker-compose down -v
|
||||
```
|
||||
|
||||
### How to deploy dolphinscheduler on Docker Swarm?
|
||||
|
||||
Assuming that the Docker Swarm cluster has been created (If there is no Docker Swarm cluster, please refer to [https://docs.docker.com/engine/swarm/swarm-tutorial/create-swarm/](https://docs.docker.com/engine/swarm/swarm-tutorial/create-swarm/))
|
||||
|
||||
Start a stack named dolphinscheduler
|
||||
|
||||
```
|
||||
docker stack deploy -c docker-stack.yml dolphinscheduler
|
||||
```
|
||||
|
||||
Stop and remove the stack named dolphinscheduler
|
||||
|
||||
```
|
||||
docker stack rm dolphinscheduler
|
||||
```
|
||||
|
||||
### How to use MySQL as the DolphinScheduler's database instead of PostgreSQL?
|
||||
|
||||
> Because of the commercial license, we cannot directly use the driver and client of MySQL.
|
||||
>
|
||||
> If you want to use MySQL, you can build a new image based on the `apache/dolphinscheduler` image as follows.
|
||||
|
||||
1. Download the MySQL driver [mysql-connector-java-5.1.49.jar](https://repo1.maven.org/maven2/mysql/mysql-connector-java/5.1.49/mysql-connector-java-5.1.49.jar) (require `>=5.1.47`)
|
||||
|
||||
2. Create a new `Dockerfile` to add MySQL driver and client:
|
||||
|
||||
```
|
||||
FROM apache/dolphinscheduler:latest
|
||||
COPY mysql-connector-java-5.1.49.jar /opt/dolphinscheduler/lib
|
||||
RUN apk add --update --no-cache mysql-client
|
||||
```
|
||||
|
||||
3. Build a new docker image including MySQL driver and client:
|
||||
|
||||
```
|
||||
docker build -t apache/dolphinscheduler:mysql .
|
||||
```
|
||||
|
||||
4. Modify all `image` fields to `apache/dolphinscheduler:mysql` in `docker-compose.yml`
|
||||
|
||||
> If you want to deploy dolphinscheduler on Docker Swarm, you need modify `docker-stack.yml`
|
||||
|
||||
5. Comment the `dolphinscheduler-postgresql` block in `docker-compose.yml`
|
||||
|
||||
6. Add `dolphinscheduler-mysql` service in `docker-compose.yml` (**Optional**, you can directly use a external MySQL database)
|
||||
|
||||
7. Modify all DATABASE environments in `docker-compose.yml`
|
||||
|
||||
```
|
||||
DATABASE_TYPE: mysql
|
||||
DATABASE_DRIVER: com.mysql.jdbc.Driver
|
||||
DATABASE_HOST: dolphinscheduler-mysql
|
||||
DATABASE_PORT: 3306
|
||||
DATABASE_USERNAME: root
|
||||
DATABASE_PASSWORD: root
|
||||
DATABASE_DATABASE: dolphinscheduler
|
||||
DATABASE_PARAMS: useUnicode=true&characterEncoding=UTF-8
|
||||
```
|
||||
|
||||
> If you have added `dolphinscheduler-mysql` service in `docker-compose.yml`, just set `DATABASE_HOST` to `dolphinscheduler-mysql`
|
||||
|
||||
8. Run a dolphinscheduler (See **How to use this docker image**)
|
||||
|
||||
### How to support MySQL datasource in `Datasource manage`?
|
||||
|
||||
> Because of the commercial license, we cannot directly use the driver of MySQL.
|
||||
>
|
||||
> If you want to add MySQL datasource, you can build a new image based on the `apache/dolphinscheduler` image as follows.

|
||||
```
|
||||
|

3. Build a new docker image including MySQL driver:
|
||||
|
||||
```
|
||||
docker build -t apache/dolphinscheduler:mysql-driver .
|
||||
```
|
||||
|
||||
4. Modify all `image` fields to `apache/dolphinscheduler:mysql-driver` in `docker-compose.yml`

||||
6. Add a MySQL datasource in `Datasource manage`
|
||||
|
||||
### How to support Oracle datasource in `Datasource manage`?
|
||||
|
||||
> Because of the commercial license, we cannot directly use the driver of Oracle.
|
||||
>
|
||||
> If you want to add Oracle datasource, you can build a new image based on the `apache/dolphinscheduler` image as follows.
|
||||
|
||||
1. Download the Oracle driver [ojdbc8.jar](https://repo1.maven.org/maven2/com/oracle/database/jdbc/ojdbc8/) (such as `ojdbc8-19.9.0.0.jar`)
|
||||
|
||||
2. Create a new `Dockerfile` to add Oracle driver:
|
||||
|
||||
```
|
||||
FROM apache/dolphinscheduler:latest
|
||||
COPY ojdbc8-19.9.0.0.jar /opt/dolphinscheduler/lib
|
||||
```
|
||||

|
||||
|
||||
```
|
||||
docker build -t apache/dolphinscheduler:oracle-driver .
|
||||
```
|
||||
|
||||
4. Modify all `image` fields to `apache/dolphinscheduler:oracle-driver` in `docker-compose.yml`
|
||||
|
||||
> If you want to deploy dolphinscheduler on Docker Swarm, you need modify `docker-stack.yml`
|
||||
|
||||
5. Run a dolphinscheduler (See **How to use this docker image**)
