## Usage
|
|
|
|
> [!IMPORTANT]
|
|
> upload-artifact/merge@v4+ is not currently supported on GHES.
|
|
|
|
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.
|
|
|
|
### Inputs
|
|
|
|
```yaml
|
|
- uses: actions/upload-artifact/merge@v4
|
|
with:
|
|
# The name of the artifact that the artifacts will be merged into
|
|
# Optional. Default is 'merged-artifacts'
|
|
name:
|
|
|
|
# A glob pattern matching the artifacts that should be merged.
|
|
# Optional. Default is '*'
|
|
pattern:
|
|
|
|
# If true, the artifacts will be merged into separate directories.
|
|
# If false, the artifacts will be merged into the root of the destination.
|
|
# Optional. Default is 'false'
|
|
separate-directories:
|
|
|
|
# If true, the artifacts that were merged will be deleted.
|
|
# If false, the artifacts will still exist.
|
|
# Optional. Default is 'false'
|
|
delete-merged:
|
|
|
|
# Duration after which artifact will expire in days. 0 means using default retention.
|
|
# Minimum 1 day.
|
|
# Maximum 90 days unless changed from the repository settings page.
|
|
# Optional. Defaults to repository settings.
|
|
retention-days:
|
|
|
|
# The level of compression for Zlib to be applied to the artifact archive.
|
|
# The value can range from 0 to 9.
|
|
# For large files that are not easily compressed, a value of 0 is recommended for significantly faster uploads.
|
|
# Optional. Default is '6'
|
|
compression-level:
|
|
```
|
|
|
|
### Outputs
|
|
|
|
| Name | Description | Example |
|
|
| - | - | - |
|
|
| `artifact-id` | GitHub ID of an Artifact, can be used by the REST API | `1234` |
|
|
| `artifact-url` | URL to download an Artifact. Can be used in many scenarios such as linking to artifacts in issues or pull requests. Users must be logged-in in order for this URL to work. This URL is valid as long as the artifact has not expired or the artifact, run or repository have not been deleted | `https://github.com/example-org/example-repo/actions/runs/1/artifacts/1234` |
|
|
|
|
## 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
|
|
```
