The upload-cloud-storage GitHub Action uploads files to a Google Cloud Storage (GCS) bucket.

Paths to files that are successfully uploaded are set as output variables and can be used in subsequent steps.

This is not an officially supported Google product, and it is not covered by a Google Cloud support contract. To report bugs or request features in a Google Cloud product, please contact Google Cloud support.

• This action requires Google Cloud credentials that are authorized to upload blobs to the specified bucket. See the Authorization section below for more information.

• This action runs using Node 16. If you are using self-hosted GitHub Actions runners, you must use runner version 2.285.0 or newer.

        destination: 'bucket-name/file'

    # Example of using the output
    - id: 'uploaded-files'
      uses: 'foo/bar@main'
      env:
        file: '${{ steps.upload-file.outputs.uploaded }}'

The file will be uploaded to gs://bucket-name/file

jobs:
  job_id:
    permissions:
      contents: 'read'
      id-token: 'write'

    steps:
    - id: 'auth'
      uses: 'google-github-actions/auth@v1'
      with:
        workload_identity_provider: 'projects/123456789/locations/global/workloadIdentityPools/my-pool/providers/my-provider'
        service_account: '[email protected]'

    - id: 'upload-folder'
      uses: 'google-github-actions/upload-cloud-storage@v1'
      with:
        path: '/path/to/folder'
        destination: 'bucket-name'

    # Example of using the output
    - id: 'uploaded-files'
      uses: 'foo/bar@main'
      env:
        files: '${{ steps.upload-folder.outputs.uploaded }}'

If the folder has the following structure:

.
└── myfolder
    ├── file1
    └── folder2
        └── file2.txt

With default configuration

- id: 'upload-files'
  uses: 'google-github-actions/upload-cloud-storage@v1'
  with:
    path: 'myfolder'
    destination: 'bucket-name'

The files will be uploaded to gs://bucket-name/myfolder/file1,gs://bucket-name/myfolder/folder2/file2.txt

Optionally, you can also specify a prefix in destination.

- id: 'upload-files'
  uses: 'google-github-actions/upload-cloud-storage@v1'
  with:
    path: 'myfolder'
    destination: 'bucket-name/myprefix'

The files will be uploaded to gs://bucket-name/myprefix/myfolder/file1,gs://bucket-name/myprefix/myfolder/folder2/file2.txt

To upload myfolder to the root of the bucket, you can set parent to false. Setting parent to false will omit path when uploading to bucket.

- id: 'upload-files'
  uses: 'google-github-actions/upload-cloud-storage@v1'
  with:
    path: 'myfolder'
    destination: 'bucket-name'
    parent: false

The files will be uploaded to gs://bucket-name/file1,gs://bucket-name/folder2/file2.txt

If path was set to myfolder/folder2, the file will be uploaded to gs://bucket-name/file2.txt

Optionally, you can also specify a prefix in destination.

- id: 'upload-files'
  uses: 'google-github-actions/upload-cloud-storage@v1'
  with:
    path: 'myfolder'
    destination: 'bucket-name/myprefix'
    parent: false

The files will be uploaded to gs://bucket-name/myprefix/file1,gs://bucket-name/myprefix/folder2/file2.txt

You can specify a glob pattern like

- id: 'upload-files'
  uses: 'google-github-actions/upload-cloud-storage@v1'
  with:
    path: 'myfolder'
    destination: 'bucket-name'
    glob: '**/*.txt'

This will particular pattern will match all text files within myfolder.

In this case, myfolder/folder2/file2.txt is the only matched file and will be uploaded to gs://bucket-name/myfolder/folder2/file2.txt.

If parent is set to false, it wil be uploaded to gs://bucket-name/folder2/file2.txt.

• path - (Required) The path to a file or folder inside the action's filesystem that should be uploaded to the bucket.

  You can specify either the absolute path or the relative path from the action:

  path: /path/to/file

  path: ../path/to/file

• destination - (Required) The destination for the file/folder in the form bucket-name or with an optional prefix in the form bucket-name/prefix

  destination: bucket-name

  In the above example, the file will be uploaded to gs://bucket-name/file

  destination: bucket-name/prefix

  In the above example, the file will be uploaded to gs://bucket-name/prefix/file

• gzip - (Optional) Upload file(s) with gzip content encoding, defaults to true.

  gzip: false

• resumable - (Optional) Enable resumable uploads, defaults to true.

  resumable: false

  In the above example, the file(s) will be uploaded without gzip content-encoding

• predefinedAcl - (Optional) Apply a predefined set of access controls to the file(s).

  predefinedAcl: projectPrivate

  In the above example, project team members get access to the uploaded file(s) according to their roles.

  Acceptable values are: authenticatedRead, bucketOwnerFullControl, bucketOwnerRead, private, projectPrivate, publicRead. See the document for details.

• headers - (Optional) Set object metadata.

  headers: |-
    content-type: application/json
    x-goog-meta-custom-field: custom-value

  In the above example, file Content-Type will be set to application/json and custom metadata with key custom-field and value custom-value will be added to it.

  Settable fields are: cache-control, content-disposition, content-encoding, content-language, content-type, custom-time. See the document for details.

  All custom metadata fields must be prefixed with x-goog-meta-.

• parent - (Optional) Whether parent dir should be included in GCS destination, defaults to true.

  parent: false

• glob - (Optional) Glob pattern.

  glob: '*.txt'

• concurrency - (Optional) Number of files to simultaneously upload, defaults to 100.

  concurrency: 10

• process_gcloudignore - (Optional) Process a .gcloudignore file present in the top-level of the repository. If true, the file is parsed and any filepaths that match are not uploaded to the storage bucket. Defaults to true.

  process_gcloudignore: true

• project_id - (Optional) Google Cloud project ID to use for billing and API requests. By default, this is extracted from the running environment.

  project_id: 'my-project'

List of successfully uploaded file(s).

For example:

- id: 'upload-file'
  uses: 'google-github-actions/upload-cloud-storage@v1'
  with:
    path: '/path/to/file'
    destination: 'bucket-name/file'

will be available in future steps as the output "uploaded":

- id: 'publish'
  uses: 'foo/bar@main'
  env:
    file: '${{ steps.upload-file.outputs.uploaded }}'

There are a few ways to authenticate this action. The caller must have permissions to access the secrets being requested.

Use google-github-actions/auth to authenticate the action. You can use Workload Identity Federation or traditional Service Account Key JSON authentication.

jobs:
  job_id:
    permissions:
      contents: 'read'
      id-token: 'write'

    steps:
    - id: 'auth'
      uses: 'google-github-actions/auth@v1'
      with:
        workload_identity_provider: 'projects/123456789/locations/global/workloadIdentityPools/my-pool/providers/my-provider'
        service_account: '[email protected]'

    - uses: 'google-github-actions/upload-cloud-storage@v1'

If you are hosting your own runners, and those runners are on Google Cloud, you can leverage the Application Default Credentials of the instance. This will authenticate requests as the service account attached to the instance. This only works using a custom runner hosted on GCP.

jobs:
  job_id:
    steps:
    - id: 'upload-file'
      uses: 'google-github-actions/upload-cloud-storage@v1'

The action will automatically detect and use the Application Default Credentials.
