#### 前言 ####

编写docker启动脚本，实现服务器上自动化启动，包括`pull代码`、`maven打包`、`docker构建镜像`、`移除容器`、`重新启动`。

#### 运行环境 ####

spring boot + docker

#### 脚本 ####

startWithDocker.sh

#!/bin/bash
      
    # 定义常量
    TAG=dev_mvp1.1 #docker tag
    APP_NAME=test-api  #项目名称
    
    # 查看所有容器
    sudo docker ps -a
    
    # 获取容器ID
    containerId=`sudo docker ps -a | grep $APP_NAME | awk '{print $1}'`
    echo "test-api contaninerId ${containerId}"
    
    sudo docker stop $containerId
    echo "stop ${APP_NAME} container ${containerId} "
    
    sudo docker container rm $containerId
    echo "rm container ${containerId}\n\n"
    
    # build core 
    cd test-core/
    echo "pull test-core code..."
    git pull
    mvn clean install -Dmaven.test.skip=true
    echo "test-core install end...\n\n"
    
    # package api
    cd ../test-api
    echo "pull test-api code..."
    git pull
    mvn clean package -Dmaven.test.skip=true
    echo "test-api package end..."
    
    # 编译镜像
    sudo docker build -t ccr.s.tencentyun.com/test/test-api:$TAG .
    sudo docker push ccr.s.tencentyun.com/test/test-api:$TAG
    
    # 获取镜像ID
    imageId=`sudo docker images | grep $TAG | grep $APP_NAME | awk '{print $3}'`
    echo "find ${APP_NAME}.${TAG} imageId ${imageId}"
    
    # 启动容器
    sudo docker run -d -m 3g -p 8000:8000 --name $APP_NAME $imageId
    
    # 获取启动的容器ID
    # 循环获取，有可能容器还没启动好 -n：newContainerId是否赋值
    newContainerId=`sudo docker ps -a | grep $APP_NAME | awk '{print $1}'`
    while [ ! -n "$newContainerId" ]
    do
      # 没获取到容器ID，重新获取
      echo "try to get containerId"
      newContainerId=`sudo docker ps -a | grep $APP_NAME | awk '{print $1}'`
    done
    
    echo "${APP_NAME} restart success!!! New containerId ${newContainerId} "
    
    # 查看日志
    sudo docker logs --tail=500 -f $newContainerId

#### DockerFile ####

Dockerfile

FROM ccr.s.tencentyun.com/test/jdk-8u281
    MAINTAINER Test<test@qq.com>
    
    LABEL SERVICE_NAME=test-api
    ENV MALLOC_ARENA_MAX=1
    ENV DEPLOY_ENV=dev
    
    ADD target/test-api.jar /opt/
    ADD entrypoint.sh /opt/
    RUN chmod a+x /opt/entrypoint.sh
    
    CMD ["/opt/entrypoint.sh"]

#### 总结 ####

编写此脚本，熟悉shell中`grep`和`awk`的使用和docker部署基本命令即可
