Github actions share workspace/artifacts between jobs?

You can use the Github Actions upload-artifact and download-artifact to share data between jobs.

In job1:

steps:
- uses: actions/checkout@v1

- run: mkdir -p path/to/artifact

- run: echo hello > path/to/artifact/world.txt

- uses: actions/upload-artifact@master
  with:
    name: my-artifact
    path: path/to/artifact

And job2:

steps:
- uses: actions/checkout@master

- uses: actions/download-artifact@master
  with:
    name: my-artifact
    path: path/to/artifact
    
- run: cat path/to/artifact/world.txt
