Rest Docker

Let’s copy docker config folder to the todo-list folder from the existing one.

cd ~/networknt/light-example-4j/eventuate/todo-list
cp -r ../todo-list.bak/docker .

There are two sub-folders in the docker module:

command-service

Since the service runs in the docker container, we need to change the MySQL hostname to use docker image name:

service.yml:

- javax.sql.DataSource:
  - com.zaxxer.hikari.HikariDataSource:
      DriverClassName: com.mysql.jdbc.Driver
      jdbcUrl: jdbc:mysql://mysql:3306/eventuate?useSSL=false
      username: mysqluser
      password: mysqlpw

To create and publish the rest-command docker image.

./build.sh 1.5.13

query-service

Since the service runs in the docker container, we need to change the MySQL hostname and Kafka hostname to use docker image name:

service.yml:

- javax.sql.DataSource:
  - com.zaxxer.hikari.HikariDataSource:
      DriverClassName: com.mysql.jdbc.Driver
      jdbcUrl: jdbc:mysql://mysql:3306/todo_db?useSSL=false
      username: mysqluser
      password: mysqlpw

kafka.yml:

bootstrapServers: kafka:9092

To create and publish the rest-query docker image.

./build.sh 1.5.13

Start command side and query side service from docker compose

Instead of start service from the command line, start service from docker compose file:

cd ~/networknt/light-example-4j/eventuate/todo-list
docker-compose up

Now we can follow the same steps in rest test to verify the service result from with curl commands.

In the next step, we are going to dockerize the hybrid services.
