HTTP Upload¶

GoReleaser supports building and pushing artifacts to HTTP servers using simple HTTP requests.

How it works¶

You can declare multiple uploads instances. All binaries generated by your builds section will be pushed to each configured upload.

If you have only one uploads instance, the configuration is as easy as adding the upload target and a name to your .goreleaser.yaml file:

uploads:
  - name: production
    target: http://some.server/some/path/example-repo-local/{{ .ProjectName }}/{{ .Version }}/

Prerequisites:

An HTTP server accepting HTTP requests
A user + password / client x509 certificate / API key with grants to upload an artifact

Note

authentication is optional and may be provided if the server requires it - user/pass is for Basic Authentication - client x509 certificate is for mutual TLS authentication (aka "mTLS")

Target¶

The target is the template of the URL to upload the artifacts to (without the name of the artifact).

An example configuration for goreleaser in upload mode binary with the target can look like:

- name: production
  mode: binary
  target: 'http://some.server/some/path/example-repo-local/{{ .ProjectName }}/{{ .Version }}/{{ .Os }}/{{ .Arch }}{{ if .Arm }}{{ .Arm }}{{ end }}'

and will result in an HTTP PUT request sent to http://some.server/some/path/example-repo-local/goreleaser/1.0.0/Darwin/x86_64/goreleaser.

Supported variables:

Version
Tag
ProjectName
ArtifactName
Os
Arch
Arm

Warning

Variables Os, Arch and Arm are only supported in upload mode binary.

For archive mode, it will also included the LinuxPackage type which is generated by nfpm and the like.

Username¶

Your configured username needs to be valid against your HTTP server.

You can have the username set in the configuration file as shown above or you can have it read from an environment variable. The configured name of your HTTP server will be used to build the environment variable name. This way we support auth for multiple instances. This also means that the name per configured instance needs to be unique per GoReleaser configuration.

The name of the environment variable will be UPLOAD_NAME_USERNAME. If your instance is named production, you can store the username in the environment variable UPLOAD_PRODUCTION_USERNAME. The name will be transformed to uppercase.

If a configured username is found in the configuration file, then the environment variable is not used at all.

This field is optional and is used only for basic http authentication.

Password¶

The password will be stored in an environment variable. The configured name of your HTTP server will be used. This way we support auth for multiple instances. This also means that the name per configured instance needs to be unique per GoReleaser configuration.

The name of the environment variable will be UPLOAD_NAME_SECRET. If your instance is named production, you need to store the secret in the environment variable UPLOAD_PRODUCTION_SECRET. The name will be transformed to uppercase.

This field is optional and is used only for basic http authentication.

Client authorization with x509 certificate (mTLS / mutual TLS)¶

If your artifactory server supports authorization with mTLS (client certificates), you can provide them by specifying the location of an x509 certificate/key pair of pem-encode files.

uploads:
- name: production
  client_x509_cert: path/to/client.cert.pem
  client_x509_key: path/to/client.key.pem
  target: 'http://some.server/some/path/example-repo-local/{{ .ProjectName }}/{{ .Version }}/{{ .Os }}/{{ .Arch }}{{ if .Arm }}{{ .Arm }}{{ end }}'

This will offer the client certificate during the TLS handshake, which your artifactory server may use to authenticate and authorize you to upload.

Server authentication¶

You can authenticate your TLS server adding a trusted X.509 certificate chain in your upload configuration.

The trusted certificate chain will be used to validate the server certificates.

You can set the trusted certificate chain using the trusted_certificates setting the upload section with PEM encoded certificates on a YAML literal block like this:

uploads:
  - name: "some HTTP/TLS server"
    #...(other settings)...
    trusted_certificates: |
      -----BEGIN CERTIFICATE-----
      MIIDrjCCApagAwIBAgIIShr2zchZo+8wDQYJKoZIhvcNAQENBQAwNTEXMBUGA1UE
      ...(edited content)...
      TyzMJasj5BPZrmKjJb6O/tOtEIJ66xPSBTxPShkEYHnB7A==
      -----END CERTIFICATE-----
      -----BEGIN CERTIFICATE-----
      MIIDrjCCApagAwIBAgIIShr2zchZo+8wDQYJKoZIhvcNAQENBQAwNTEXMBUGA1UE
      ...(edited content)...
      TyzMJasj5BPZrmKjJb6O/tOtEIJ66xPSBTxPShkEYHnB7A==
      -----END CERTIFICATE-----

Customization¶

Of course, you can customize a lot of things:

# .goreleaser.yaml
uploads:
  # You can have multiple upload instances.
  -
    # Unique name of your upload instance. Used to identify the instance.
    name: production

    # HTTP method to use.
    # Default: PUT
    method: POST

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

    # File extensions to filter for.
    # This might be useful if you have multiple packages with different
    # extensions with the same ID, and need to upload each extension to
    # a different place (e.g. nFPM packages).
    #
    # Default: empty.
    # Since: v1.7.
    exts:
    - deb
    - rpm

    # Upload mode. Valid options are `binary` and `archive`.
    # If mode is `archive`, variables _Os_, _Arch_ and _Arm_ for target name are not supported.
    # In that case these variables are empty.
    # Default is `archive`.
    mode: archive

    # Template of the URL to be used as target of the HTTP request
    target: https://some.server/some/path/example-repo-local/{{ .ProjectName }}/{{ .Version }}/

    # Custom artifact name (defaults to false)
    # If enable, you must supply the name of the Artifact as part of the Target
    # URL as it will not be automatically append to the end of the URL, its
    # pre-computed name is available as _ArtifactName_ for example
    # target: https://some.server/some/path/example-repo-local/{{ .ArtifactName }};deb.distribution=xenial
    custom_artifact_name: true

    # An optional username that will be used for the deployment for basic authn
    username: deployuser

    # Client certificate and key (when provided, added as client cert to TLS connections)
    # Since: v1.11.
    client_x509_cert: /path/to/client.cert.pem
    client_x509_key: /path/to/client.key.pem

    # An optional header you can use to tell GoReleaser to pass the artifact's
    # SHA256 checksum within the upload request.
    # Default is empty.
    checksum_header: -X-SHA256-Sum

    # A map of custom headers e.g. to support required content types or auth schemes.
    # Default is empty.
    custom_headers:
      JOB-TOKEN: "{{ .Env.CI_JOB_TOKEN }}"

    # Upload checksums (defaults to false)
    checksum: true

    # Upload signatures (defaults to false)
    signature: true

   # Certificate chain used to validate server certificates
    trusted_certificates: |
      -----BEGIN CERTIFICATE-----
      MIIDrjCCApagAwIBAgIIShr2zchZo+8wDQYJKoZIhvcNAQENBQAwNTEXMBUGA1UE
      ...(edited content)...
      TyzMJasj5BPZrmKjJb6O/tOtEIJ66xPSBTxPShkEYHnB7A==
      -----END CERTIFICATE-----

These settings should allow you to push your artifacts into multiple HTTP servers.
