Blobs (s3, gcs, azblob)

The blobs allows you to upload artifacts to Amazon S3, Azure Blob and Google GCS.

Customization

# .goreleaser.yaml
blobs:
  # You can have multiple blob configs
  - # Cloud provider name:
    # - s3 for AWS S3 Storage
    # - azblob for Azure Blob Storage
    # - gs for Google Cloud Storage
    #
    # Templates: allowed
    provider: azblob

    # Set a custom endpoint, useful if you're using a minio backend or
    # other s3-compatible backends.
    #
    # Implies s3ForcePathStyle and requires provider to be `s3`
    #
    # Templates: allowed
    endpoint: https://minio.foo.bar

    # Sets the bucket region.
    # Requires provider to be `s3`
    #

    # Disables SSL
    # Requires provider to be `s3`
    disable_ssl: true

    # Bucket name.

    bucket: goreleaser-bucket

    # IDs of the artifacts you want to upload.
    ids:

    # Whether to disable this particular upload configuration.

    disable: '{{ neq .BLOB_UPLOAD_ONLY "foo" }}'

    # You can add extra pre-existing files to the bucket.
    # The filename on the release will be the last part of the path (base).
    # If another file with the same name exists, the last one found will be used.
    # These globs can also include templates.
    extra_files:
      - glob: ./path/to/file.txt
      - glob: ./glob/**/to/**/file/**/*

      - glob: ./single_file.txt
        # Templates: allowed
        name_template: file.txt # note that this only works if glob matches 1 file only

    # Additional templated extra files to uploaded.
    # Those files will have their contents pass through the template engine,

Authentication

GoReleaser's blob pipe authentication varies depending upon the blob provider as mentioned below:

S3 Provider

S3 provider support AWS default credential provider chain in the following order:

  • Environment variables.
  • Shared credentials file.
  • If your application is running on an Amazon EC2 instance, IAM role for Amazon EC2.

Azure Blob Provider

blobs:
  - provider: azblob
    bucket: releases?storage_account=myazurestorage

Storage account is set over URL param storage_account in bucket or in environment variable AZURE_STORAGE_ACCOUNT

It supports authentication with

GCS Provider

GCS provider uses Application Default Credentials in the following order:

  • Environment Variable (GOOGLE_APPLICATION_CREDENTIALS)
  • Default Service Account from the compute instance (Compute Engine, Kubernetes Engine, Cloud function etc).

ACLs

There is no common way to set ACLs across all bucket providers, so, go-cloud does not support it yet.

You are expected to set the ACLs on the bucket/directory/etc, depending on your provider.
