For what I know there is no way to restart a workflow automatically through configurations yet...
However, there are different ways to achieve a similar result using workflows implementation with Github Actions. It won't be exactly a restart, as the workaround would be to start the workflow again if it fails.
The first option could be to use another workflow with the workflow_run trigger to check if the first workflow ran successfully, and if not, send a dispatch event to run it again (in that case, you would have to add a repository_dispatch trigger to the first workflow).
Another option could be to add 2 steps at the end of your first job (build) to save the job status as an artifact.
- name: Create file status_job1.txt and write the job status into it
if: always()
run: echo ${{ job.status }} > status_job1.txt
- name: Upload file status_job1.txt as an artifact
if: always()
uses: actions/upload-artifact@v1
with:
name: pass_status_job1
path: status_job1.txt
Then, a second job would always check the output of the first one:
job2:
runs-on: ubuntu-latest
needs: [job1]
if: always()
steps:
- name: Download artifact pass_status_job1
uses: actions/download-artifact@v1
with:
name: pass_status_job1
- name: Set the status of Job 1, as output parameter
id: set_outputs
run: echo "::set-output name=status_job1::$(<pass_status_job1/status_job1.txt)"
- name: Show the values of the output
run: |
# using the syntax steps.<step_id>.outputs.<output_name> to access the output parameter
echo "status_job1 = ${{ steps.set_outputs.outputs.status_job1 }}"
# other steps or commands to perform an operation according to its value.
[...]
For example, at the end of job2, you could send a dispatch event to the same workflow if the status of the job1 is failure (in that case, you would have to add a repository_dispatch trigger to the workflow as well) to start the workflow again (as I explained, it won't be exactly a restart as this will create a new workflow run).
Here is an action to create a repository dispatch event, or you can do it directly calling the Github API
