从JSON文件遍历JSON对象

Question

我试图从JSON文件中迭代对象数组，但我无法。我现在得到这个错误:

为job 'create'评估'strategy'时出错。.github/workflows/rollingdeploymentyml (Line: 66, Col: 15):不期望序列

这是当前的工作流文件:

name: Rolling Deploy
on:
push:
branches: [ "main" ]
jobs:
servers:
runs-on: ubuntu-latest
outputs:
matrix: ${{ steps.read-json.outputs.matrix }}
environment: Staging
steps:
... a few other steps in here to create the json file
- name: Read JSON
id: read-json
run: |
JSON=$(cat ./neededServers.json)
echo "matrix=${JSON//'%'/'%25'}" >> $GITHUB_OUTPUT

create:
needs: servers
runs-on: ubuntu-latest
strategy:
matrix: ${{ fromJson(needs.servers.outputs.matrix) }}
steps:
- name: Test
run: echo "${{matrix.reference}}"

我在没有策略的create中运行echo ${{needs.servers.outputs.matrix}}，并且它打印JSON文件。这里也有一个示例JSON文件:

[
{
"config":"small",
"ID":"1234",
"memory":"4096",
"vcpus":"2"
},{
"config":"small",
"ID":"2345",
"memory":"4096",
"vcpus":"2"
}
]

我不确定是我做错了什么，还是这是不可能的。

Answer 1

JSON应该包含数组的"include"键:

{
"include": [
{
"config":"small",
"ID":"1234",
"memory":"4096",
"vcpus":"2"
},
{
"config":"small",
"ID":"1234",
"memory":"4096",
"vcpus":"2"
}
]
}
