Builds API

API used by runners to receive and update builds.

Note: This API is intended to be used only by Runners as their own communication channel. For the consumer API see the Builds API.

Authentication

This API uses two types of authentication:

1. Unique Runner's token which is the token assigned to the Runner after it has been registered.

2. Using the build authorization token. This is project's CI token that can be found under the Builds section of a project's settings. The build authorization token can be passed as a parameter or a value of BUILD-TOKEN header.

These two methods of authentication are interchangeable.

Builds

Runs oldest pending build by runner

POST /ci/api/v1/builds/register

Attribute	Type	Required	Description
token	string	yes	Unique runner token

curl -X POST "https://gitswarm.example.com/ci/api/v1/builds/register" -F "token=t0k3n"

Update details of an existing build

PUT /ci/api/v1/builds/:id

Attribute	Type	Required	Description
id	integer	yes	The ID of a project
token	string	yes	Unique runner token
state	string	no	The state of a build
trace	string	no	The trace of a build

curl -X PUT "https://gitswarm.example.com/ci/api/v1/builds/1234" -F "token=t0k3n" -F "state=running" -F "trace=Running git clone...\n"

Incremental build trace update

Using this method you need to send trace content as a request body. You also need to provide the Content-Range header with a range of sent trace part. Note that you need to send parts in the proper order, so the begining of the part must start just after the end of the previous part. If you provide the wrong part, then GitLab CI API will return 416 Range Not Satisfiable response with a header Range: 0-X, where X is the current trace length.

For example, if you receive Range: 0-11 in the response, then your next part must contain a Content-Range: 11-... header and a trace part covered by this range.

For a valid update API will return 202 response with:

• Build-Status: {status} header containing current status of the build,
• Range: 0-{length} header with the current trace length.

PATCH /ci/api/v1/builds/:id/trace.txt

Parameters:
