AWS ECS蓝色/绿色CodePipeline:尝试读取图像工件时发生异常 [英] AWS ECS Blue/Green CodePipeline: Exception while trying to read the image artifact

问题描述

我想创建一个CodePipeline，该代码从CodeCommit源构建一个容器映像，然后以蓝色/绿色方式将新映像部署到我的ECS服务(EC2启动类型)中.

I wanted to create a CodePipeline which builds a container image from CodeCommit source and afterwards deploys the new image in Blue/Green fashion to my ECS service (EC2 launchtype).

• 源阶段是CodeCommit，其中已经包含appspec.json
  以及taskdef.json
• 构建阶段正在构建新的集装箱将其成功推送到ECR，文件imagedefinition.json是在此步骤中创建的BuildArtifact，包含容器及其最近创建的图像及其与CodeCommit提交ID对应的标签.
• 部署阶段由操作"Amazon ECS(蓝色/绿色)"构成SourceArtifact和BuildArtifact作为InputArtifacts，来自SourceArtifact和图像的appspec和taskdefBuildArtifact中的描述，以最终部署新的蓝色/绿色容器.

问题在于BuildArtifact中的图像定义.管道在部署"阶段失败，并显示以下错误:

The problem is with the image definition from the BuildArtifact. The pipeline fails in the Deploy phase with error:

"无效的动作配置尝试从工件中读取图像工件文件时发生异常:BuildArtifact."

"" Invalid action configuration Exception while trying to read the image artifact file from the artifact: BuildArtifact. ""

如何正确配置"Amazon ECS(蓝色/绿色)"部署阶段，以便它可以使用最近创建的映像并进行部署....通过替换taskdef.json中的占位符IMAGE_NAME?

How to properly configure the "Amazon ECS (Blue/Green)" deploy phase, so that it can use the recently created image and deploy it....by replacing placeholder IMAGE_NAME inside taskdef.json ?

任何暗示高度赞赏:D

Any hint highly appreciated :D

推荐答案

在这里回答我自己的问题，希望它可以帮助遇到相同情况的其他人.

answering my own question here, hopefully it helps others who facing the same situation.

1. imagedefinitions.json文件不适用于部署操作"Amazon ECS蓝色/绿色".为此，您必须在构建步骤中创建文件 imageDetail.json ，并将其作为工件提供给部署步骤.如何 ?这是我的buildspec.yaml底部的样子:

1. the file imagedefinitions.json is inappropriate for deploy action "Amazon ECS Blue/Green". For that you have to create file imageDetail.json within the build step and provide it as artifact to the deploy step. How ? This is how the bottom of my buildspec.yaml looks like:

      - printf '{"ImageURI":"%s"}' $REPOSITORY_URI:$IMAGE_TAG > imageDetail.json
artifacts:
  files: 
    - 'image*.json'
    - 'appspec.yaml'
    - 'taskdef.json'
  secondary-artifacts:
    DefinitionArtifact:
      files:
        - appspec.yaml
        - taskdef.json
    ImageArtifact:
      files:
        - imageDetail.json

1. 在CodePipeline的部署阶段，将DefinitionArtifact和ImageArtifact用作输入工件，并在相应的部分" Amazon ECS任务定义"和" AWS CodeDeploy AppSpec文件"中进行配置.".

1. In the Deploy phase of CodePipeline, use DefinitionArtifact and ImageArtifact as Input Artifacts and configure them in the corresponding section "Amazon ECS task definition" and "AWS CodeDeploy AppSpec file".

确保您的appspec.yaml包含任务定义的占位符.这是我的appspec.yaml:

Ensure that your appspec.yaml contains placeholder for the task definition. Here is my appspec.yaml:

version: 0.0

Resources:
  - TargetService:
      Type: AWS::ECS::Service
      Properties:
        TaskDefinition: <TASK_DEFINITION>
        LoadBalancerInfo:
          ContainerName: "my-test-container"
          ContainerPort: 8000

还要确保您的taskdef.json包含最终图像的占位符，例如

Also ensure that your taskdef.json contains placeholder for the final image, like

...
"image": <IMAGE1_NAME>,
...

通过选择输入工件"ImageArtifact"和占位符在"动态更新任务定义图像-可选"部分的蓝色/绿色部署阶段的代码管道配置中使用该占位符>< IMAGE1_NAME>

1. use that placeholder in the codepipeline config of your blue/green deploy phase in the section "Dynamically update task definition image - optional" by choosing the input artifact as "ImageArtifact" and the placeholder <IMAGE1_NAME>
