我的工作流程需要循环执行这些步骤,这非常适合策略/矩阵.
I have workflow that needs to have a loop for the steps, which is perfect with strategy/matrix.
唯一的问题是策略/矩阵需要由常量设置.
The only problem is that strategy/matrix needs to be set by a constant.
是否可以将策略矩阵与脚本输出一起使用?
Is it possible to use strategy matrix with a output of a script?
name: tests on: [push] jobs: test: runs-on: ${{ ubuntu-latest }} strategy: fail-fast: false matrix: versions: $(./script.py) steps: - uses: actions/checkout@v2 ....... 推荐答案您可以在一个作业中以JSON格式生成矩阵并将其设置为第二个作业.
You can generate matrix in JSON in one job and set it to the second job.
GitHub在4月添加了此功能: github.blog/changelog/2020-04-15-github-actions-new-workflow-features/
GitHub added this feature in April: github.blog/changelog/2020-04-15-github-actions-new-workflow-features/
name: build on: push jobs: job1: runs-on: ubuntu-latest outputs: matrix: ${{ steps.set-matrix.outputs.matrix }} steps: - id: set-matrix run: echo "::set-output name=matrix::{\"include\":[{\"project\":\"foo\",\"config\":\"Debug\"},{\"project\":\"bar\",\"config\":\"Release\"}]}" job2: needs: job1 runs-on: ubuntu-latest strategy: matrix: ${{fromJson(needs.job1.outputs.matrix)}} steps: - run: echo ${{ matrix.project }} - run: echo ${{ matrix.config }}第一个作业将输出变量 matrix 设置为包含两种配置的JSON:
First job sets output variable matrix to JSON that contains two configurations:
{ "include": [ { "project": "foo", "config": "Debug" }, { "project": "bar", "config": "Release" } ] }.yml中的等效值:
Equivalent in .yml:
job2: strategy: matrix: include: - project: foo config: Debug - project: bar config: Release别忘了对引号 \'''进行转义并在一行中打印JSON.
Do not forget to escape quotes \" and print JSON in one line.
它检测更改的文件,并为更改的目录运行构建作业.如果目录名称以OS名称开头,则使用该名称作为运行文件.
It detects changed files and runs build job for changed directories. If directory name starts with OS name, it uses that name as runs-on.
