+docker需要配置代理
+
+## Dockerfile
+
+首先就是通过编写Dockerfile来构建image，  
+内部就是通过maven构建jar包来运行。
+
+maven拉镜像的时候可能也需要代理，或者换源，所以我把maven中的settings.xml配置copy到image里 则可以在里面配置源，设置代理等等。
+
+```Dockerfile
+FROM maven:3.8.5-openjdk-11 AS build
+WORKDIR /app
+COPY pom.xml .
+COPY src ./src
+COPY settings.xml /usr/share/maven/conf/settings.xml
+RUN mvn clean package -DskipTests -X
+
+
+FROM openjdk:11-jdk
+WORKDIR /app
+COPY --from=build /app/target/*.jar app.jar
+EXPOSE 8080
+ENTRYPOINT ["java", "-jar", "app.jar"]
+
+```
+
+## Docker-compose
+
+因为需要等待mysql启动完成后再启动service，否则service连接不上mysql，则日志  
+所以需要加上health check
+
+```yaml
+version: "3.8"
+
+services:
+  db:
+    image: mysql:5.7
+    container_name: mysql-db
+    environment:
+      MYSQL_ROOT_PASSWORD: 123456
+      MYSQL_DATABASE: vote
+      MYSQL_USER: ultraman
+      MYSQL_PASSWORD: 123456
+    volumes:
+      - db_data:/var/lib/mysql
+      - ./vote.sql:/docker-entrypoint-initdb.d/vote.sql
+    ports:
+      - "3306:3306"
+    healthcheck:
+      test: ["CMD", "mysqladmin", "ping", "-h", "localhost", "-p123456"]
+      interval: 10s
+      timeout: 5s
+      retries: 5
+      start_period: 30s
+
+  app:
+    build: .
+    container_name: vote-system-app
+    depends_on:
+      db:
+        condition: service_healthy
+    ports:
+      - "8080:8080"
+
+volumes:
+  db_data:
+
+```
