jenkins构建后，aws ecs update-service无法正常运行期望计数= 1，但运行= 0

Question

什么工作正常

我已经使用terraform脚本成功创建了AWS ECS集群

具有以下参数

max_instance_size = 2
min_instance_size = 1
desired_capacity  = 1

"maximumPercent": 100,
"minimumHealthyPercent": 0

当我创建此Cluster时，一切正常。我的应用程序已启动并且正在运行，并且可以通过Load Balancer进行访问。

给什么问题

现在我有一个詹金斯工作要做，请按照以下步骤操作

1. 结帐
2. 构建应用程序
3. 创建Docker映像
4. 将Docker映像推送到Hub
5. 通过任务定义更新部署映像。

这是詹金斯代码段

stage("Deploy") {

sh  "sed -e  's;%BUILD_TAG%;${BUILD_NUMBER};g' accountupdateecs-task-defination.json > accountupdateecs-task-defination-${BUILD_NUMBER}.json"

def currTaskDef = sh (returnStdout: true,script:  "aws ecs describe-task-definition  --task-definition ${taskFamily}| egrep 'revision'| tr ',' ' '| awk '{print \$2}'").trim()  

def currentTask = sh (returnStdout: true,script:  "aws ecs list-tasks  --cluster ${clusterName} --family ${taskFamily} --output text | egrep 'TASKARNS' | awk '{print \$2}' ").trim()

if(currTaskDef) {sh  "aws ecs update-service  --cluster ${clusterName} --service ${serviceName} --task-definition ${taskFamily}:${currTaskDef} --desired-count 0 "}

if (currentTask) {sh "aws ecs stop-task --cluster ${clusterName} --task ${currentTask}"}

sh  "aws ecs register-task-definition  --family ${taskFamily} --cli-input-json ${taskDefile}"

def taskRevision = sh (returnStdout: true, script:  "aws ecs describe-task-definition  --task-definition ${taskFamily} | egrep 'revision' | tr ',' ' ' | awk '{print \$2}'").trim()

sh  "aws ecs update-service  --force-new-deployment --cluster ${clusterName} --service ${serviceName} --task-definition ${taskFamily}:${taskRevision} --desired-count 1" 

}

问题

成功执行作业后，我总是可以在群集中看到

desired-count = 1
running       = 0

该应用程序不可用。

这是詹金斯的成功日志
