应用部署

使用Dockerfile构建应用

docker build -t ddd-user-web:2022.0.0 .

docker run -it --name app1 --network mynet --network-alias app1 -p  8081:8080 -d ddd-user-web:2022.0.0
docker run -it --name app2 --network mynet --network-alias app2 -p  8082:8080 -d ddd-user-web:2022.0.0
docker run -it --name app3 --network mynet --network-alias app3 -p  8083:8080 -d ddd-user-web:2022.0.0

mysql

docker run -it --name mysql --network mynet --network-alias mysql -p 3306:3306 --restart always  -e TZ=Asia/Shanghai -e MYSQL_ROOT_PASSWORD=123456 -d mysql

canal

docker run -it --name canal --network mynet --network-alias canal -p 11111:11111 -d canal/canal-server

mysql添加canal用户

CREATE USER canal IDENTIFIED WITH mysql_native_password BY 'canal';  
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO 'canal'@'%';
-- GRANT ALL PRIVILEGES ON *.* TO 'canal'@'%' ;
FLUSH PRIVILEGES;

修改配置

vi canal-server/conf/example/instance.properties 
canal.master.position=
