I am trying to validation JSONs using Github workflow. But the problem here is that I have multiple JSON files that I need to validate. I tried looking up for a way to validate all of them everywhere but there is none that I could find.
My work flow code is here.
name: Validate JSONs
on: [pull_request]
jobs:
verify-json-validation:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v1
- name: Validate JSON
uses: docker://orrosenblatt/validate-json-action:latest
env:
INPUT_SCHEMA: /.github/workflows/schema.json
INPUT_JSONS: /*.json
I am unable to understand how I can add the INPUT_JSONS path dynamically so that it could validate all jsons.
That usecase is part of pending tickets:
OrRosenblatt/validate-json-action issue 22: [Feature] Detect JSON Files
OrRosenblatt/validate-json-action PR 23: Added Glob Functionality
By making your own fork of that action, using PR 23 mentioned above, you would have support for *.json.

In our github organization we have a lot of repositories. All of them shall convert JIRA tickets names in comments/PRs like XYZ-123 to links to the corresponding JIRA ticket. This is possible with Autolinking.
The downside of this approach ist, that Autolinking is supporting only Prefixes (no regex-es like GitLab). This results in one entry per JIRA projekt (i.e if I want to support ABC-123 and XYZ-123 two entries with the prefix ABC- and XYZ- are required).
What makes things worse is, that Autolinking has to be configured per repository. This means I have to add all Autolink entries to every Repository in our company (and maintain these lists).
Is there no simpler solution?
There does not seem to be any native simpler solution than the official Configuring autolinks to reference external resources.
You would need a GitHub Action to update a PR, replacing/making the JIRA links as you want them to be.
Example, with a .github/workflows/pr_update.yml:
name: PR update
on:
pull_request:
types: [opened]
jobs:
update_pr:
name: Update PR
runs-on: ubuntu-latest
steps:
- uses: tzkhan/pr-update-action#v2
with:
repo-token: "${{ secrets.GITHUB_TOKEN }}"
base-branch-regex: '[A-Za-z\d-_.\\/]+'
head-branch-regex: '^([A-Za-z])+-\d+'
title-template: '%headbranch%: '
body-template: |
Jira issue: %headbranch%
---
body-update-action: 'prefix'
body-uppercase-base-match: false
I'm trying to reduce the amount of files I have for my workflows from 4 to 1. And with that my on is like this:
on:
pull_request:
types: [opened, synchronize, closed]
push:
branches: [master]
I know it's possible to use if in workflows but looking at the documentation I didn't find which parameters I should use to trigger the correct jobs when:
Pull request is opened
Pull request is closed
Push is made to a existing pull request
Push is made to a brach
The piece of documentation that touches on how to use if is this one.
You can use it at the job level. Consider the following example to execute a job only when the PR has been closed and merged (not just closed):
name: Build Your App
on:
pull_request:
types: [ closed ]
jobs:
build:
# this job will only run if the PR has been merged, not just 'closed'
if: github.event.pull_request.merged == true
runs-on: ubuntu-latest
steps:
- name: Checkout repository
uses: actions/checkout#v2
with:
fetch-depth: '0'
And you can also use it at the step level, to execute or not the step based on the {{ expression }} evaluation, as the documentation shows.
Based on your ask, I would use the information on the github.event.* payload. To do that I use to re-create the conditions and triggers on a test repository and print it to the console. Then I know what I have to look for in each kind of event. It's like debugging the events. This is the documentation to do that.
I have two workflows, the first one runs a build script and generates an artifact.
The first one is triggered when a pull request is created like this:
name: build
on:
pull_request:
types: [opened, edited, ready_for_review, reopened]
The second flow runs when the first is done, by using the workflow_runtrigger like this:
on:
workflow_run:
workflows: ["build"]
types:
- "completed"
The second flow has to be separate and run after the first one. When done it is supposed to post a comment on the PR that triggered the first workflow, but I am unable to find out how.
According to the Github Action Docs this is one of the typical use cases, as per this qoute:
For example, if your pull_request workflow generates build artifacts, you can create
a new workflow that uses workflow_run to analyze the results and add a comment to the
original pull request.
But I can't seem to find out how. I can get the first workflow's id in the 2nd workflow's context.payload.workflow_run.id, but workflow_run should also have about the pull request, but they`re empty.
What am I doing wrong, and where can I find the necessary info to be able to comment on my created pull request?
You're not doing anything wrong, it's just that the Pull Request datas from the first workflow are not present in the Github Context of the second workflow.
To resolve your problem, you could send the Pull Request datas you need from the first workflow to the second workflow.
There are different ways to do it, for example using a dispatch event (instead of a workflow run), or an artifact.
For the artifact, it would look like something as below:
In the FIRST workflow, you get the PR number from the github.event. Then you save that number into a file and upload it as an artifact.
- name: Save the PR number in an artifact
shell: bash
env:
PULL_REQUEST_NUMBER: ${{ github.event.number }}
run: echo $PULL_REQUEST_NUMBER > pull_request_number.txt
- name: Upload the PULL REQUEST number
uses: actions/upload-artifact#v2
with:
name: pull_request_number
path: ./pull_request_number.txt
In the SECOND workflow, you get the artifact and the Pull Request number from the FIRST workflow, using the following GitHub Apps:
- name: Download workflow artifact
uses: dawidd6/action-download-artifact#v2.11.0
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
workflow: <first_workflow_name>.yml
run_id: ${{ github.event.workflow_run.id }}
- name: Read the pull_request_number.txt file
id: pull_request_number_reader
uses: juliangruber/read-file-action#v1.0.0
with:
path: ./pull_request_number/pull_request_number.txt
- name: Step to add comment on PR
[...]
I have one action (a yaml file) for deploying a docker image to Google Cloud Run.
I would like to receive Slack or Email messages informing the build and push results.
How could the message action be triggered after build action is completed?
Is it possible to get the result of the build action?
There are 2 options of doing this:
Use a second job inside the same workflow.yml together with the needs keyword
Create a separate notify.yml workflow that uses the workflow_run event as a trigger
1. Same workflow, separate job with needs keyword
In your workflow.yml file you simply define two jobs like this (leveraging the needs: build configuration in the second job):
name: CI build and notify
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- name: Deploy Docker image to Google Cloud Run
run: ...
notify:
needs: build
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- name: Notify Slack and send eMail
run: ...
As the docs state, the second notify job will only start if the first build job succeeded:
Identifies any jobs that must complete successfully before this job
will run.
Here's a screenshot of how this approach can look like practically from my own project (I have a second publish-snapshot job instead of your notify job - but the concept stays the same):
There's also a way to always let the notify job run, even if the build job failed. You have to enhance the needs with a if: always() configuration then.
2. Separate workflow, using the workflow_run event as a trigger
Using the workflow_run event as a trigger we end up having 2 separate GitHub Actions workflow yaml files:
build.yml
name: CI build
on: [push]
jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- name: Deploy Docker image to Google Cloud Run
run: ...
notify.yml
name: CI notify
# Only trigger, when the build workflow succeeded
on:
workflow_run:
workflows: ["CI build"]
types:
- completed
jobs:
notify:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v2
- name: Notify Slack and send eMail
run: ...
A crucial point here is that the name: CI build definition of the first yaml file must exactly match the workflow_run: workflows: ["CI build"] definition in the second yaml file. Another point is that this approach needs to be done on the default branch (which is mostly main or master) as the docs state:
Note: This event will only trigger a workflow run if the workflow file
is on the default branch.
Here's also a full example project using the 1st option if you're interested.
First, you are mixing terms here. According to GitHub Actions documentation a single YAML file is called a workflow (not an action) and consists of jobs. Jobs contain a sequence of steps (including actions) that are executed one after another. A particular workflow execution is called a run. Having that in mind lets go the questions.
How could the message workflow be triggered after build workflow is completed?
You can use GitHub API to trigger a webhook event called repository_dispatch (only for the base branch) or workflow_dispatch. This can be easily done using a dedicated Repository Dispach action in your build workflow.
Is it possible to get the result of the build workflow?
Yes, the result of the workflow run can be obtained using given GitHub API
But if you only want to send the build result notification of the currently executed workflow you don't need to create a separate workflow and trigger it from the parent. You can use dedicated Slack actions or e-mail actions.
you can try in step 2 the following directive:
needs: step-1-job-name
just after job name
The best method i've found for reusable workflows in the same repository is https://docs.github.com/en/actions/using-workflows/reusing-workflows
In the workflow you want to re-use (let's call it wf1):
# wf1.yml
on:
workflow_call:
In the workflow you want to call wf1 from (let's call this wf2)
# wf2.yml
jobs:
call-wf1:
uses: ./.github/workflows/wf1.yml
secrets: inherit
In order to get data from one workflow to another, check out https://docs.github.com/en/actions/using-workflows/reusing-workflows#using-outputs-from-a-reusable-workflow.
First, set up your reusable workflow to output the data:
name: Reusable workflow
on:
workflow_call:
# Map the workflow outputs to job outputs
outputs:
firstword:
description: "The first output string"
value: ${{ jobs.example_job.outputs.output1 }}
secondword:
description: "The second output string"
value: ${{ jobs.example_job.outputs.output2 }}
jobs:
example_job:
name: Generate output
runs-on: ubuntu-latest
# Map the job outputs to step outputs
outputs:
output1: ${{ steps.step1.outputs.firstword }}
output2: ${{ steps.step2.outputs.secondword }}
steps:
- id: step1
run: echo "::set-output name=firstword::hello"
- id: step2
run: echo "::set-output name=secondword::world"
Now use it in the calling workflow:
name: Call a reusable workflow and use its outputs
on:
workflow_dispatch:
jobs:
job1:
# local repo
# uses: .github/workflows/called-workflow.yml#v1
# other repo
uses: octo-org/example-repo/.github/workflows/called-workflow.yml#v1
job2:
runs-on: ubuntu-latest
needs: job1
steps:
- run: echo ${{ needs.job1.outputs.firstword }} ${{ needs.job1.outputs.secondword }}
How could the message action be triggered after build action is completed?
This should now (August 2020) be possible with "GitHub Actions improvements for fork and pull request workflows"
Another frequently-requested feature for Actions is a way to trigger one workflow based on the completion of another workflow.
For example, you may want to take the results of a CI workflow and run some further analysis.
The new workflow_run event enables you to trigger a new workflow when one or more workflows are requested or completed.
Runs triggered by the workflow_run event always use the default branch for the repository, and have access to a read/write token as well as secrets.
As an example, as a maintainer you could set up a workflow that takes the artifacts generated by the pull request workflow, do some analysis, and post comments back to the pull request.
This event is also available as a web hook.
I've recently added a static analysis step to my GitHub actions. However, it is somewhat expensive so I'm trying to reduce the number of times that this step is run. I've already added an appropriate filter so that it only runs on one OS and so that it only runs on my "feature" branches. However, I would like to also filter out any checkins that include "WIP" in their commit message. (The theory being that there is no point in performing the full analysis until it is no longer a "Work In Progress".)
I've searched through the docs, expecting I would find an object I could use as part of the github context object, but to no avail.
Any ideas on how I can accomplish this goal?
If you want to see exactly what I'm doing, the action Yaml is as follows. I'm hoping to find some change I can make to the if statement on the Static Analysis item that would accomplish my goal.
name: On Push
on: [push]
jobs:
build:
runs-on: ${{ matrix.os }}
strategy:
matrix:
os: [ubuntu-latest, macos-latest]
steps:
- uses: actions/checkout#v1
- name: Build
run: |
./configure
make -j 4
- name: Run tests
run: |
make -j 4 check
- name: Static Analysis
if: runner.os == 'macOS' && startsWith(github.ref, 'refs/heads/feature/')
run: |
make analyze
You can make use of the event property on the github context to access the push payload.
Add the following to the step that does the analysis:
if: !startsWith(github.event.head_commit.message, 'WIP')
Related to your issue, you now (Feb. 2021) have:
GitHub Actions: Skip pull request and push workflows
with [skip ci]
GitHub Actions now supports skipping push and pull_request workflows by looking for some common keywords in your commit message.
If any commit message in your push or the HEAD commit of your PR contains the strings [skip ci], [ci skip], [no ci], [skip actions], or [actions skip] workflows triggered on the push or pull_request events will be skipped.
This is not as flexible as a custom commit message (like your "WIP"), but it still can help.
if: ${{ !startsWith(github.event.head_commit.message, '#NORUN') }}
Syntax should be like this
