我如何使用我的Gitlab管道的输出，作为管道中的值?

Question

我有一个构建AMI映像的管道，但是我还希望能够在之后的附加阶段中使用该AMI ID。我不确定如何捕获输出(AMI ID)作为进一步向下管道的值。

这里是我的.gitlab-ci.yml文件:

image:
name: hashicorp/packer:latest
entrypoint:
- '/usr/bin/env'
- 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
before_script:
- packer --version
stages:
- build
- deploy
get_packer:
stage: build
artifacts:
paths:
- packer
script:
- echo "Fetching packer"
- wget https://releases.hashicorp.com/packer/1.5.5/packer_1.5.5_linux_amd64.zip
- unzip packer_1.5.5_linux_amd64.zip
- chmod +x packer
deploy_packer:
stage: deploy
script:
- echo "Deploying Packer Build"
- cd aws
- packer build -only="*rhel-stig*" .

这是输出的尾部输出AMI ID的管道:

Build 'rhel.amazon-ebs.rhel-stig' finished after 8 minutes 17 seconds.
==> Wait completed after 8 minutes 17 seconds
==> Builds finished. The artifacts of successful builds are:
--> rhel.amazon-ebs.rhel-stig: AMIs were created:
us-east-1: ami-08155b7eaa9e0274f
Cleaning up project directory and file based variables
00:00
Job succeeded

注意它是如何输出区域和AMI -ID的，如果我想像这样添加到管道上，我如何在同一管道中使用AMI ID ?

理论.gitlab-ci.yml文件

image:
name: hashicorp/packer:latest
entrypoint:
- '/usr/bin/env'
- 'PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
before_script:
- packer --version
stages:
- build
- deploy
- test
get_packer:
stage: build
artifacts:
paths:
- packer
script:
- echo "Fetching packer"
- wget https://releases.hashicorp.com/packer/1.5.5/packer_1.5.5_linux_amd64.zip
- unzip packer_1.5.5_linux_amd64.zip
- chmod +x packer
deploy_packer:
stage: deploy
script:
- echo "Deploying Packer Build"
- cd aws
- packer build -only="*rhel-stig*" .
test_image:
stage: test
script: 
- (Do something with the outputted AMI ID from the deploy stage) 

更新:

初始添加后出现新错误

Build 'rhel.amazon-ebs.rhel-stig' finished after 9 minutes 22 seconds.
==> Wait completed after 9 minutes 22 seconds

您需要做的第一件事是配置打包器构建以使用manifest后处理器:

post-processor "manifest" {
output = "manifest.json"
strip_path = true
}

这将在构建结束时生成一个包含AMI ID的json文件。

然后，您可以使用dotenv工件构造来与后续作业共享变量。

下面是它的工作原理:

deploy_packer:
stage: deploy
script:
- echo "Deploying Packer Build"
- cd aws
- packer build -only="*rhel-stig*" .
- AMI_ID=$(jq -r '.builds[-1].artifact_id' manifest.json | cut -d ":" -f2)
- echo "AMI_ID=$AMI_ID" > image.env
artifacts:
reports:
dotenv: aws/image.env
test_image:
stage: test
script: 
- echo $AMI_ID
needs:
- job: build
artifacts: true
