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 ${REGION} | jq .repositories[].repositoryUri | tr -d '"'`
#根据构建的tag标签去创建一个生成任务定义的json文件
sudo sed  -e "s;%TAG%;${tag};g"  -e "s;%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 ${REGION} | jq .repositories[].repositoryUri | tr -d '"'`
#Replace the build number and respository URI placeholders with the constants above
sudo sed  -e "s;%TAG%;${tag};g" -e "s;%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 ${REGION} | jq .repositories[].repositoryUri | tr -d '"'`
#Replace the build number and respository URI placeholders with the constants above
sudo sed -e "s;%TAG%;${tag};g" -e "s;%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。
