这期内容当中丸趣 TV 小编将会给大家带来有关 Jenkins 怎样手动更新 AWS 上面的 ECS 服务，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。

以上是整个部署更新的流程图：

1. 开发人员对上线的代码打一个 tag，然后把带 tag 的代码推到 AWS codecommit 上面。

git   add  -A   *

git   commit   -a -m ${tag}

git   tag    ${tag}

git  push   origin    分支    ${tag}

5.jenkins 进行代码构建作业：

（首先需要安装插件：Amazon ECR plugin、Docker plugin）

以下是 jenkins 项目配置的示例：

以下是构建 image 和把 image 推送到 ECR 上

以下是更新 ECS 服务的设置（适用于更新接口、对外接口、定时任务、前端、app 的 H5 前端）：

例子：（api 的配置）

#!/bin/bash

REGION= ap-northeast-1     #区域
REPOSITORY_NAME= exchange-api    #ECR 的存储库
CLUSTER= online-exchange     #集群名称
SERVICE_NAME= online-exchange-api     #服务名称
FAMILY= online_exchange-api      # 任务定义名称
NAME= online-exchange-api        # 容器名称
TASKDEFNAME= online_exchange-api     ## 任务定义名称

# 列出存储库的 URL

REPOSITORY_URI=`aws ecr describe-repositories –repository-names ${REPOSITORY_NAME} –region ${REGION} | jq .repositories[].repositoryUri | tr -d `

# 根据构建的 tag 标签去创建一个生成任务定义的 json 文件
sudo sed  -e %TAG%;${tag};g  -e %REPOSITORY_URI%;${REPOSITORY_URI};g /opt/update-exchange/update-api/online-ecs-exchange-api.json /opt/update-exchange/update-api/${NAME}-${tag}.json

# 根据 ECR 里面的 URL, 创建一个新的任务定义
aws ecs register-task-definition –family ${FAMILY} –cli-input-json file:///opt/update-exchange/update-api/${NAME}-${tag}.json  –region ${REGION}
SERVICES=`aws ecs describe-services –services ${SERVICE_NAME} –cluster ${CLUSTER} –region ${REGION} | jq .failures[]`

# 获取最新的版本
REVISION=`aws ecs describe-task-definition –task-definition ${TASKDEFNAME} –region ${REGION} | jq .taskDefinition.revision`

# 创建或者更新服务
if [$SERVICES ==]; then
  echo entered existing service
  DESIRED_COUNT=`aws ecs describe-services –services ${SERVICE_NAME} –cluster ${CLUSTER} –region ${REGION} | jq .services[].desiredCount`
  if [${DESIRED_COUNT} = 0 ]; then
    DESIRED_COUNT= 1
  fi
  aws ecs update-service –cluster ${CLUSTER} –region ${REGION} –service ${SERVICE_NAME} –task-definition ${FAMILY}:${REVISION} 
else
  echo entered new service
  aws ecs create-service –service-name ${SERVICE_NAME} –desired-count 2 –task-definition ${FAMILY} –cluster ${CLUSTER} –region ${REGION}
fi

# 更新服务成功之后，执行清理镜像，清理文件。
docker  rmi   786381498352.dkr.ecr.ap-northeast-1.amazonaws.com/exchange-api:latest
docker  rmi   786381498352.dkr.ecr.ap-northeast-1.amazonaws.com/exchange-api:${tag}
\rm  /opt/update-exchange/update-api/${NAME}-${tag}.json

以下是 ECS 更新的配置（适用于更新撮合、结算）：

例子 (结算):

#!/bin/bash

REGION= ap-northeast-1
REPOSITORY_NAME= exchange-deal
CLUSTER= online-exchange
SERVICE_NAME= online-exchange-deal
FAMILY= online_exchange-deal
NAME= online-exchange-deal
TASKDEFNAME= online_exchange-deal

REPOSITORY_URI=`aws ecr describe-repositories –repository-names ${REPOSITORY_NAME} –region ${REGION} | jq .repositories[].repositoryUri | tr -d `

#Replace the build number and respository URI placeholders with the constants above
sudo sed  -e %TAG%;${tag};g -e %REPOSITORY_URI%;${REPOSITORY_URI};g /opt/update-exchange/update-deal/online-ecs-exchange-deal.json /opt/update-exchange/update-deal/${NAME}-${tag}.json

#Register the task definition in the repository
aws ecs register-task-definition –family ${FAMILY} –cli-input-json file:///opt/update-exchange/update-deal/${NAME}-${tag}.json  –region ${REGION}
SERVICES=`aws ecs describe-services –services ${SERVICE_NAME} –cluster ${CLUSTER} –region ${REGION} | jq .failures[]`

#Get latest revision
REVISION=`aws ecs describe-task-definition –task-definition ${TASKDEFNAME} –region ${REGION} | jq .taskDefinition.revision`
#首先把预期数改为 0，再删除服务，再创建新的服务。
if [$SERVICES ==]; then
   echo entered existing service
   aws ecs update-service –cluster  ${CLUSTER}   –service  ${SERVICE_NAME}  –desired-count 0
   sleep 10
   aws ecs delete-service –cluster  ${CLUSTER}   –service ${SERVICE_NAME}
   sleep 100
   aws ecs create-service –cluster ${CLUSTER} –service-name ${SERVICE_NAME} –task-definition ${FAMILY}:${REVISION} –desired-count 1 –launch-type FARGATE –network-configuration awsvpcConfiguration={subnets=[subnet-04a486cb94c9c9032,subnet-0d93a8c5452781c8f],securityGroups=[sg-0c66800c0bdd235fc],assignPublicIp=ENABLED}
else
    echo service does not exist
    echo create a new service
   aws ecs create-service –cluster ${CLUSTER} –service-name ${SERVICE_NAME} –task-definition ${FAMILY}:${REVISION} –desired-count 1 –launch-type FARGATE –network-configuration awsvpcConfiguration={subnets=[subnet-04a486cb94c9c9032,subnet-0d93a8c5452781c8f],securityGroups=[sg-0c66800c0bdd235fc],assignPublicIp=ENABLED}
fi

# 更新服务成功之后，执行清理镜像，清理文件。
docker  rmi   786381498352.dkr.ecr.ap-northeast-1.amazonaws.com/exchange-deal:latest
docker  rmi   786381498352.dkr.ecr.ap-northeast-1.amazonaws.com/exchange-deal:${tag}
\rm  /opt/update-exchange/update-deal/${NAME}-${tag}.json
 

先删除服务的目的是为了绝对的保证服务只会存在一个，最后有一个清理镜像，清理文件，是为了减少磁盘的压力。

以下是 ECS 更新的配置（适用于更新推送）：

例子 (推送)：

#!/bin/bash

REGION= ap-northeast-1
REPOSITORY_NAME= exchange-ws
CLUSTER= online-exchange
SERVICE_NAME= online-exchange-ws
FAMILY= online_exchange-ws
NAME= online-exchange-ws
TASKDEFNAME= online_exchange-ws

REPOSITORY_URI=`aws ecr describe-repositories –repository-names ${REPOSITORY_NAME} –region ${REGION} | jq .repositories[].repositoryUri | tr -d `

#Replace the build number and respository URI placeholders with the constants above
sudo sed -e %TAG%;${tag};g -e %REPOSITORY_URI%;${REPOSITORY_URI};g /opt/update-exchange/update-ws/online-ecs-exchange-ws.json /opt/update-exchange/update-ws/${NAME}-${tag}.json

#Register the task definition in the repository
aws ecs register-task-definition –family ${FAMILY} –cli-input-json file:///opt/update-exchange/update-ws/${NAME}-${tag}.json  –region ${REGION}
SERVICES=`aws ecs describe-services –services ${SERVICE_NAME} –cluster ${CLUSTER} –region ${REGION} | jq .failures[]`

#Get latest revision
REVISION=`aws ecs describe-task-definition –task-definition ${TASKDEFNAME} –region ${REGION} | jq .taskDefinition.revision`

# 首先把预期数改为 0，等待服务中没有运行得任务，再去更新任务。
aws ecs update-service –cluster online-exchange   –service  online-exchange-ws  –desired-count 0

while :
do
    count=`aws ecs describe-services –cluster ${CLUSTER} –service ${SERVICE_NAME} | grep runningCount | tail -n1 | egrep -oE [0-9] `
    sleep 30
    if [$count -eq 0];then
       aws ecs update-service –cluster ${CLUSTER} –region ${REGION} –service ${SERVICE_NAME} –task-definition ${FAMILY}:${REVISION} –desired-count 1
       exit
    fi
done
#更新服务成功之后，执行清理镜像，清理文件。
docker  rmi   786381498352.dkr.ecr.ap-northeast-1.amazonaws.com/exchange-ws:latest
docker  rmi   786381498352.dkr.ecr.ap-northeast-1.amazonaws.com/exchange-ws:${tag}
\rm  /opt/update-exchange/update-ws/${NAME}-${tag}.json
