如何根据分支机构设置工作流环境变量 [英] How to set workflow env variables depending on branch
问题描述
我目前有两个GitHub动作工作流文件,它们几乎相同,只有一个配置为对分支 master
上的push / pull_requests做出反应,另一个在生产
。
分段工作流程如下所示:
env:
GCLOUD_PROJECT:my-project-stg
VERCEL_TARGET:暂存
上:
推送:
分支机构:[master ]
pull_request:
分支机构:[master]
生产工作流程如下:
env:
GCLOUD_PROJECT:my-project-prd
VERCEL_TARGET:生产
开:
推:
分支:[生产]
pull_request:
分支:[生产]
其余的工作流程文件是相同的,因此显然不是很干。
我想拥有1个单个工作流程文件并以某种方式进行切换赌注基于分支名称的两组变量之间。有没有一种方法可以实现这一目标,或者我可能是从错误的角度来解决这一问题?
无法从作业设置工作流级环境变量。每个作业都在自己的计算机上运行,并且在其中设置env变量只会影响该作业的所有后续步骤。您可以创建一个工件并使用它,或者声明并设置作业输出。后者适用于字符串值。
这里是一个示例:
name : Main;
上:
推送:
分支机构:
-主
-生产
pull_request:
分支机构:
-主
-生产
工作:
初始运行:
运行:ubuntu最新
输出:
gcloud_project:$ {{ steps.setvars.outputs.gcloud_project}}
阶段:$ {{steps.setvars.outputs.phase}}
步骤:
-名称:取消上一个工作流程
使用:styfle/cancel-workflow-action@0.4.0
与:
access_token:$ {{github.token}}
-名称:设置变量
id:setvars
运行:|
if [[" $ {{github.base_ref}}" ==大师; || " $ {{{github.ref}}" ==参考/负责人/主 ]];然后
echo :: set-output name = gcloud_project :: my-project-dev
echo :: set-output name = phase :: staging;
fi
if [[" $ {{github.base_ref}}" ==生产 || " $ {{{github.ref}}" ==参考/标题/制作; ]];然后
echo :: set-output name = gcloud_project :: my-project-prd
echo :: set-output name = phase :: production;
fi
打印:
运行:ubuntu最新
需要:init
步骤:
-名称:Print
运行:echo gcloud_project = $ {{needs.init.outputs.gcloud_project}}
I currently have two GitHub actions workflow files that are pretty much identical, only one is configured to react to push/pull_requests on branch master
the other on production
.
The staging workflow starts like this:
env:
GCLOUD_PROJECT: my-project-stg
VERCEL_TARGET: staging
on:
push:
branches: [ master ]
pull_request:
branches: [ master ]
The production workflow starts like:
env:
GCLOUD_PROJECT: my-project-prd
VERCEL_TARGET: production
on:
push:
branches: [ production ]
pull_request:
branches: [ production ]
The rest of the workflow files is the same, so this is clearly not very DRY.
I would like to have 1 single workflow file and somehow switch between two sets of variables based on the branch name. Is there a way to achieve this or am I maybe approach this from the wrong angle?
If it were possible to extend both workflow files on a shared base definition that would also solve it I guess.
It is not possible to set workflow-level environment variables from a job. Each job runs in its own machine and setting an env variable there only affects all of the later steps in that job.
There are currently two ways to share data between jobs; either you create an artifact and use that, or you declare and set job outputs. The latter works for string values.
Here's an example:
name: "Main"
on:
push:
branches:
- master
- production
pull_request:
branches:
- master
- production
jobs:
init:
runs-on: ubuntu-latest
outputs:
gcloud_project: ${{ steps.setvars.outputs.gcloud_project }}
phase: ${{ steps.setvars.outputs.phase }}
steps:
- name: Cancel previous workflow
uses: styfle/cancel-workflow-action@0.4.0
with:
access_token: ${{ github.token }}
- name: Set variables
id: setvars
run: |
if [[ "${{github.base_ref}}" == "master" || "${{github.ref}}" == "refs/heads/master" ]]; then
echo "::set-output name=gcloud_project::my-project-dev"
echo "::set-output name=phase::staging"
fi
if [[ "${{github.base_ref}}" == "production" || "${{github.ref}}" == "refs/heads/production" ]]; then
echo "::set-output name=gcloud_project::my-project-prd"
echo "::set-output name=phase::production"
fi
print:
runs-on: ubuntu-latest
needs: init
steps:
- name: Print
run: echo "gcloud_project=${{needs.init.outputs.gcloud_project}}"
