|

## Merging multiple artifacts
|
||||
|
||||
In `v3`, multiple uploads from multiple jobs could be done to the same Artifact. This would result in a single archive, which could be useful for sending to upstream systems outside of Actions via API or UI downloads.
|
||||
|
||||
```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: all-my-files # NOTE: same artifact name
|
||||
path: file-${{ matrix.runs-on }}.txt
|
||||
```
|
||||
|
||||
The single `all-my-files` artifact would contain the following:
|
||||
|
||||
```
|
||||
.
|
||||
∟ file-ubuntu-latest.txt
|
||||
∟ file-macos-latest.txt
|
||||
∟ file-windows-latest.txt
|
||||
```
|
||||
|
||||
To achieve the same in `v4` you can change it like so:
|
||||
|
||||
```diff
|
||||
jobs:
|
||||
upload:
|
||||
strategy:
|
||||
matrix:
|

|
||||
steps:
|
||||
- name: Create a File

||||

|
||||

||||

||||

|
||||
- name: all-my-files
|
||||

|
||||
path: file-${{ matrix.runs-on }}.txt
|
||||
+ merge:
|
||||
+ runs-on: ubuntu-latest
|
||||
+ needs: upload
|
||||
+ steps:
|
||||
+ - name: Merge Artifacts

|
||||
+ with:
|
||||
+ name: all-my-files
|
||||
+ pattern: my-artifact-*
|
||||
```
|
||||
|
||||
Note that this will download all artifacts to a temporary directory and reupload them as a single artifact. For more information on inputs and other use cases for `actions/upload-artifact/merge@v4`, see [the action documentation](../merge/README.md).

Note: this actions can only merge artifacts created with actions/upload-artifact@v4+

|

This sub-action is a helper to merge multiple artifacts after they are created. To do so, it will download multiple artifacts to a temporary directory and reupload them as a single artifact.
|
||||
|
||||
For most cases, this may not be the most efficient solution. See [the migration docs](../docs/MIGRATION.md#multiple-uploads-to-the-same-named-artifact) on how to download multiple artifacts to the same directory on a runner. This action should only be necessary for cases where multiple artifacts will need to be downloaded outside the runner environment, like downloads via the UI or REST API.

## Examples
|
||||
|
||||
TODO(robherley): add examples
|
||||
For each of these examples, assume we have a prior job matrix that generates three artifacts: `my-artifact-a`, `my-artifact-b` and `my-artifact-c`.
|
||||
|
||||
e.g.
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
upload:
|
||||
runs-on: ubuntu-latest
|
||||
|
||||
strategy:
|
||||
matrix:
|
||||
foo: [a, b, c]
|
||||
|
||||
steps:
|
||||
- name: Run a one-line script
|
||||
run: echo "hello from job ${{ matrix.foo }}" > file-${{ matrix.foo }}.txt
|
||||
- name: Upload
|
||||
uses: actions/upload-artifact@v4
|
||||
with:
|
||||
name: my-artifact-${{ matrix.foo }}
|
||||
path: file-${{ matrix.foo }}.txt
|
||||
```
|
||||
|
||||
Each of the following examples will use the `needs: upload` as a prerequesite before any merging operations.
|
||||
|
||||
### Combining all artifacts in a workflow run
|
||||
|
||||
By default (with no inputs), calling this action will take all the artifacts in the workflow run and combined them into a single artifact called `merged-artifacts`:
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
# ... <upload job> ...
|
||||
merge:
|
||||
runs-on: ubuntu-latest
|
||||
needs: upload
|
||||
steps:
|
||||
- name: Merge Artifacts
|
||||
uses: actions/upload-artifact/merge@v4
|
||||
```
|
||||
|
||||
This will result in an artifact called `merged-artifacts` with the following content:
|
||||
|
||||
```
|
||||
.
|
||||
∟ file-a.txt
|
||||
∟ file-b.txt
|
||||
∟ file-c.txt
|
||||
```
|
||||
|
||||
To change the name of the artifact and filter on what artifacts are added, you can use the `name` and `pattern` inputs:
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
# ... <upload job> ...
|
||||
merge:
|
||||
runs-on: ubuntu-latest
|
||||
needs: upload
|
||||
steps:
|
||||
- name: Merge Artifacts
|
||||
uses: actions/upload-artifact/merge@v4
|
||||
with:
|
||||
name: my-amazing-merged-artifact
|
||||
pattern: my-artifact-*
|
||||
```
|
||||
|
||||
### Prefix directories in merged artifact
|
||||
|
||||
To prevent overwriting files in artifacts that may have the same name, you can use the `separate-directories` to prefix the extracted files with directories (named after the original artifact):
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
# ... <upload job> ...
|
||||
merge:
|
||||
runs-on: ubuntu-latest
|
||||
needs: upload
|
||||
steps:
|
||||
- name: Merge Artifacts
|
||||
uses: actions/upload-artifact/merge@v4
|
||||
with:
|
||||
separate-directories: true
|
||||
```
|
||||
|
||||
This will result in the following artifact structure:
|
||||
|
||||
```
|
||||
.
|
||||
∟ my-artifact-a
|
||||
∟ file-a.txt
|
||||
∟ my-artifact-b
|
||||
∟ file-b.txt
|
||||
∟ my-artifact-c
|
||||
∟ file-c.txt
|
||||
```
|
||||
|
||||
### Deleting artifacts after merge
|
||||
|
||||
After merge, the old artifacts may no longer be required. To automatically delete them after they are merged into a new artifact, you can use `delete-merged` like so:
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
# ... <upload job> ...
|
||||
merge:
|
||||
runs-on: ubuntu-latest
|
||||
needs: upload
|
||||
steps:
|
||||
- name: Merge Artifacts
|
||||
uses: actions/upload-artifact/merge@v4
|
||||
with:
|
||||
delete-merged: true
|
||||
```
|
||||
|
||||
After this runs, the matching artifact (`my-artifact-a`, `my-artifact-b` and `my-artifact-c`) will be merged.
|
||||
|
||||
### Retention and Compression Level
|
||||
|
||||
Similar to actions/upload-artifact, both [`retention-days`](../README.md#retention-period) and [`compression-level`](../README.md#altering-compressions-level-speed-v-size) are supported:
|
||||
|
||||
```yaml
|
||||
jobs:
|
||||
# ... <upload job> ...
|
||||
merge:
|
||||
runs-on: ubuntu-latest
|
||||
needs: upload
|
||||
steps:
|
||||
- name: Merge Artifacts
|
||||
uses: actions/upload-artifact/merge@v4
|
||||
with:
|
||||
retention-days: 1
|
||||
compression-level: 9
|
||||
```
