Parse metadata json from docker bake github action

问题

以下是您要翻译的部分：

"I need to grab the outputs from the metadata output on the docker/bake action: https://github.com/docker/bake-action#outputs

Here's the bake action:

  1.       - name: Build all Dockerfiles images listed in docker-compose.yml
  2.         uses: docker/bake-action@v2.3.0
  3.         id: monorepo-build
  4.         env:
  5.           ....
  6.         with:
  7.           push: true
  8.           files: docker-bake.hcl
  9.           set: |
  10.             *.args.environment=${{ steps.vars.outputs.env }}
  11.             *.args.site=${{ inputs.SITE }}
  12.             *.args.GH_PACKAGE_READ=${{ secrets.GH_TOKEN }}

Then immediately after I run:

  1.       - name: Test getting the metadata output from Bake step 
  2.         run: |
  3.           touch metadata.json
  4.           echo "${{ steps.monorepo-build.outputs.metadata }}" > metadata.json
  5.           cat metadata.json | jq '.mykey'

So as you see I've tried to echo the metadata into a json file first and then parse that using jq to get the top level key mykey. I've also tried to parse directly by echoing "${{ steps.monorepo-build.outputs.metadata }}" | jq '.mykey'

I'm getting the error parse error: Invalid numeric literal at line 2, column 8. Here's the JSON output from the file:

  1. {
  2. 	mykey: {
  3. 		containerimage.buildinfo: {
  4. 			frontend: dockerfile.v0,
  5. 			attrs: {
  6. 				...
  7. 			sources: [{
  8. 				...
  9. 			}]
  10. 		},
  11. 		containerimage.descriptor: {
  12. 			mediaType: ********
  13. 			digest: **********
  14. 			size: 856
  15. 		},
  16. 		containerimage.digest: *****************
  17. 		image.name: ****************
  18. 	}
  19. }

I've noticed it doesn't have double quotes around the key/value pairs. When I add double quotes on in my local copy and run jq it seems fine.

How can I sort this?"

得分: 2

代码部分不翻译，以下是翻译好的部分：

问题出在您的 echo 中的双引号 ("")，如下所示：

  1. echo "${{ steps.monorepo-build.outputs.metadata }}"

将导致类似以下的结果：

  1. echo "{
  2.     "mykey": {
  3.         "containerimage.buildinfo": {
  4.             "frontend": "dockerfile.v0,"
  5.             "attrs": {

所以修复方法要么使用单引号：

  1.   - name: 测试从 Bake 步骤获取元数据输出
  2.     run: |
  3.       touch metadata.json
  4.       echo '${{ steps.monorepo-build.outputs.metadata }}' > metadata.json
  5.       cat metadata.json | jq '.mykey'

要么使用 cat：

  1. - name: 测试从 Bake 步骤获取元数据输出
  2.   run: |
  3.     cat << EOF >  metadata.json
  4.     ${{ steps.monorepo-build.outputs.metadata }}
  5.     EOF
  6.     
  7.     cat metadata.json | jq '.mykey'

或者，根据评论中 Azeem 提到的可能有不同的方法：

  1.   - name: 测试从 Bake 步骤获取元数据输出
  2.     run: |
  3.       jq '.myKey' <<< $METADATA > some-output.json
  4.     env:
  5.       METADATA: ${{ steps.monorepo-build.outputs.metadata }}
英文:

The issue is with the double quotes ("") in your echo, this:

  1. echo "${{ steps.monorepo-build.outputs.metadata }}"

would lead to something like:

  1. echo "{
  2.     "mykey": {
  3.         "containerimage.buildinfo": {
  4.             "frontend": "dockerfile.v0,"
  5.             "attrs": {

So the fix is to either use single quotes:

  1.   - name: Test getting the metadata output from Bake step 
  2.     run: |
  3.       touch metadata.json
  4.       echo '${{ steps.monorepo-build.outputs.metadata }}' > metadata.json
  5.       cat metadata.json | jq '.mykey'

or use cat:

  1. - name: Test getting the metadata output from Bake step 
  2.   run: |
  3.     cat << EOF >  metadata.json
  4.     ${{ steps.monorepo-build.outputs.metadata }}
  5.     EOF
  6.     
  7.     cat metadata.json | jq '.mykey'

Or maybe a different approach as Azeem mentioned in the comments:

  1.   - name: Test getting the metadata output from Bake step 
  2.     run: |
  3.       jq '.myKey' <<< $METADATA > some-output.json
  4.     env:
  5.       METADATA: ${{ steps.monorepo-build.outputs.metadata }}
