如何使用aws cdk在现有的ecs集群上运行Fargate Task

Question

我有一个ECS集群，它将由我的cdk堆栈创建。在我的ECS服务栈部署之前，我必须运行一个fargate任务来为我的应用程序生成构建文件和配置。我想在现有的Ecs集群中运行一个独立的任务。

Answer 1

有两个问题。我会试着回答这两个问题:

1. 首先你需要通过CDK
运行Fargate任务

您需要创建一个规则，该规则按时间表(或其他事件)运行ECS任务

import { Rule, Schedule } from '@aws-cdk/aws-events';
import { EcsTask } from '@aws-cdk/aws-events-targets';
new Rule(this, 'ScheduleRule', {
schedule: schedule,
targets: [
new EcsTask({
cluster,
taskDefinition: task,
}),
],
});

2. 第二个-我如何使用现有的集群

你可以通过属性

找到你的集群

import { Cluster } from '@aws-cdk/aws-ecs';
let cluster = Cluster.fromClusterAttributes(this, 'cluster_id', {
clusterName: "CLUSTER_NAME", securityGroups: [], vpc: iVpc
});

：你可以通过一些自定义事件触发你的任务:

new Rule(this, 'EventPatternRule', {
eventPattern: {
"version": "0",
"id": "CWE-event-id",
"detail-type": "CodePipeline Pipeline Execution State Change",
"source": "aws.codepipeline",
"account": "123456789012",
"time": "2017-04-22T03:31:47Z",
"region": "us-east-1",
"resources": [
"arn:aws:codepipeline:us-east-1:123456789012:pipeline:myPipeline"
],
"detail": {
"pipeline": "myPipeline",
"version": "1",
"state": "STARTED",
"execution-id": "01234567-0123-0123-0123-012345678901"
}
}
targets: [
new EcsTask({
cluster,
taskDefinition: task,
}),
],
});
