API for the Screwdriver CD service
Screwdriver is a self-contained, pluggable service to help you build, test, and continuously deliver software using the latest containerization technologies.
Table of Contents
Screwdriver began as a hack for simplified interfacing with Jenkins at Yahoo in 2012. As the volume of builds increased, it became clear that Jenkins was not stable or feasible to use at the scale we were running builds. In 2016, we rebuilt Screwdriver from scratch in open source with our best coding practices and CICD goals in mind. Screwdriver is executor and SCM-agnostic, meaning you can choose whichever plugin better suits your need or build your own. It's completely free and open source, and our team is actively maintaining the code.

Installation and Usage
This API comes preloaded with 16 (sixteen) resources:
- coverage - optional
Three (3) option for datastores:
- Postgres, MySQL, and Sqlite (
Three (3) options for executor:
- Kubernetes (
- Docker (
- Nomad (
Three (3) options for SCM:
- Github (
- Gitlab (
- Bitbucket (
To use Screwdriver, you will need the following prerequisites:
$ git clone email@example.com:screwdriver-cd/screwdriver.git ./ $ npm install $ vim ./config/local.yaml # See below for configuration $ npm start info: Server running at http://localhost:8080
From a Prebuilt Docker image
$ vim ./local.yaml # See below for configuration $ docker run --rm -it --volume=`pwd`/local.yaml:/config/local.yaml -p 8080 screwdrivercd/screwdriver:stable info: Server running at http://localhost:8080
Our in-a-box script brings up an entire Screwdriver instance (ui, api, and log store) locally for you to play with. Follow instructions at https://github.com/screwdriver-cd/in-a-box#screwdriver-in-a-box.
This chart bootstraps the whole Screwdriver ecosystem and also nginx ingress controller.
Screwdriver already defaults most configuration, but you can override defaults using a
local.yaml or environment variables.
To continue set up, follow the instructions for cluster management.
executor: plugin: k8s k8s: options: kubernetes: host: kubernetes.default token: this-is-a-real-token launchVersion: stable scms: github: plugin: github config: oauthClientId: totally-real-client-id oauthClientSecret: another-real-client-secret secret: a-really-real-secret username: sd-buildbot email: firstname.lastname@example.org
Example overriding with environment variables:
$ export K8S_HOST=127.0.0.1 $ export K8S_TOKEN=this-is-a-real-token $ export SECRET_OAUTH_CLIENT_ID=totally-real-client-id $ export SECRET_OAUTH_CLIENT_SECRET=another-real-client-secret
All the possible environment variables are defined here.
Note: You might run into memory issues running all the unit tests. You can update your
~/.bashrc file with the line below to ensure there's enough memory for tests to run:
functional-* repositories to your organization from screwdriver-cd-test
.func_config to the root of the Screwdriver API folder with your username, github token, access key, host, and organization for test:
GIT_TOKEN=YOUR-GITHUB-TOKEN SD_API_TOKEN=YOUR-SD-API-TOKEN SD_API_HOST=YOUR-SD-API-HOST SD_API_PROTOCOL=PROTOCOL-FOR-SD-API // e.g.PROTOCOL=http; by default it is https TEST_ORG=YOUR-TEST-ORGANIZATION TEST_USERNAME=YOUR-GITHUB-USERNAME TEST_SCM_HOSTNAME=YOUR-TEST-SCM-HOSTNAME // e.g. TEST_SCM_HOSTNAME=mygithub.com; by default it is github.com TEST_SCM_CONTEXT=YOUR-TEST-SCM-CONTEXT // e.g.TEST_SCM_CONTEXT=bitbucket; by default it is github
With environment variables
Set the environment variables:
$ export GIT_TOKEN=YOUR-GITHUB-TOKEN $ export SD_API_TOKEN=YOUR-SD-API-TOKEN $ export SD_API_HOST=YOUR-SD-API-HOST $ export SD_API_PROTOCOL=PROTOCOL-FOR-SD-API $ export TEST_ORG=YOUR-TEST-ORGANIZATION $ export TEST_USERNAME=YOUR-GITHUB-USERNAME $ export TEST_SCM_HOSTNAME=YOUR-TEST-SCM-HOSTNAME $ export TEST_SCM_CONTEXT=YOUR-TEST-SCM-CONTEXT
Then run the cucumber tests:
npm run functional
