Several behavioral differences exist between Artifact actions `v3` and below vs `v4`. This document outlines common scenarios in `v3`, and how they would be handled in `v4`.
|
||
|
|
|
||
|
|
## Multiple uploads to the same named Artifact
|
||
|
|
|
||
|
|
In `v3`, Artifacts are _mutable_ so it's possible to write workflow scenarios where multiple jobs upload to the same Artifact like so:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
jobs:
|
||
|
|
upload:
|
||
|
|
strategy:
|
||
|
|
matrix:
|
||
|
|
runs-on: [ubuntu-latest, macos-latest, windows-latest]
|
||
|
|
runs-on: ${{ matrix.runs-on }}
|
||
|
|
steps:
|
||
|
|
- name: Create a File
|
||
|
|
run: echo "hello from ${{ matrix.runs-on }}" > file-${{ matrix.runs-on }}.txt
|
||
|
|
- name: Upload Artifact
|
||
|
|
uses: actions/upload-artifact@v3
|
||
|
|
with:
|
||
|
|
name: my-artifact # NOTE: same artifact name
|
||
|
|
path: file-${{ matrix.runs-on }}.txt
|
||
|
|
download:
|
||
|
|
needs: upload
|
||
|
|
runs-on: ubuntu-latest
|
||
|
|
steps:
|
||
|
|
- name: Download All Artifacts
|
||
|
|
uses: actions/download-artifact@v3
|
||
|
|
with:
|
||
|
|
path: my-artifact
|
||
|
|
- run: ls -R my-artifact
|
||
|
|
```
|
||
|
|
|
||
|
|
This results in a directory like so:
|
||
|
|
|
||
|
|
```
|
||
|
|
my-artifact/
|
||
|
|
file-macos-latest.txt
|
||
|
|
file-ubuntu-latest.txt
|
||
|
|
file-windows-latest.txt
|
||
|
|
```
|
||
|
|
|
||
|
|
In v4, Artifacts are immutable (unless deleted). So you must change each of the uploaded Artifacts to have a different name and filter the downloads by name to achieve the same effect:
|
||
|
|
|
||
|
|
```diff
|
||
|
|
jobs:
|
||
|
|
upload:
|
||
|
|
strategy:
|
||
|
|
matrix:
|
||
|
|
runs-on: [ubuntu-latest, macos-latest, windows-latest]
|
||
|
|
runs-on: ${{ matrix.runs-on }}
|
||
|
|
steps:
|
||
|
|
- name: Create a File
|
||
|
|
run: echo "hello from ${{ matrix.runs-on }}" > file-${{ matrix.runs-on }}.txt
|
||
|
|
- name: Upload Artifact
|
||
|
|
- uses: actions/upload-artifact@v3
|
||
|
|
+ uses: actions/upload-artifact@v4
|
||
|
|
with:
|
||
|
|
- name: my-artifact
|
||
|
|
+ name: my-artifact-${{ matrix.runs-on }}
|
||
|
|
path: file-${{ matrix.runs-on }}.txt
|
||
|
|
download:
|
||
|
|
needs: upload
|
||
|
|
runs-on: ubuntu-latest
|
||
|
|
steps:
|
||
|
|
- name: Download All Artifacts
|
||
|
|
- uses: actions/download-artifact@v3
|
||
|
|
+ uses: actions/download-artifact@v4
|
||
|
|
with:
|
||
|
|
path: my-artifact
|
||
|
|
+ pattern: my-artifact-*
|
||
|
|
+ merge-multiple: true
|
||
|
|
- run: ls -R my-artifact
|
||
|
|
```
|
||
|
|
|
||
|
|
In `v4`, the new `pattern:` input will filter the downloaded Artifacts to match the name specified. The new `merge-multiple:` input will support downloading multiple Artifacts to the same directory. If the files within the Artifacts have the same name, the last writer wins.
