Environment Variables

Screwdriver exports a set of environment variables that you can rely on during build runtime.

Note: Environment variables set in one job cannot be accessed in another job. To pass variables between jobs, use metadata.

Build Specific

General

Name	Description
SD_BUILD_ID	The ID of the build
SD_EVENT_ID	The ID of the event
SD_JOB_ID	The ID of the job
SD_JOB_NAME	Job name (e.g.: `main`)
SD_PARENT_BUILD_ID	Bracketed list of build(s) that trigger(s) this build. (e.g.: `[12345 23456]`)
SD_PARENT_EVENT_ID	ID of the parent event if this was a restart
SD_PR_PARENT_JOB_ID	ID of the real job of PR. For example, in `PR-1:main` build, this ENV references the ID of `main` job
SD_PIPELINE_ID	The ID of the pipeline
SD_PIPELINE_NAME	The name of the pipeline (e.g.: `d2lam/myPipeline`)
SD_PRIVATE_PIPELINE	Whether the pipeline is private(true) or not(false)
SD_PULL_REQUEST	Pull Request number (e.g.: `1`; blank if non-PR)
SD_STEP_EXIT_CODE	Exit code from previously executed steps, only available at teardown steps (e.g.: `0` if all previous steps have passed, otherwise, the latest non-zero exit code)
SD_STEP_NAME	Current step name, only available for user-defined steps, not setup or teardown commands (e.g.: during teardown, would be set to the last successfully executed step)
SD_TEMPLATE_FULLNAME	Full template name the job is using (e.g.: `d2lam/myTemplate`; blank if not using template)
SD_TEMPLATE_NAME	Name of the template the job is using (e.g.: `myTemplate`; blank if not using template)
SD_TEMPLATE_NAMESPACE	Namespace of the template the job is using (e.g.: `d2lam`; blank if not using template)
SD_TEMPLATE_VERSION	Version of the template the job is using (blank if not using template)
SD_BUILD_CLUSTER_NAME	The name of the build cluster
SD_TOKEN	JWT token for the build
SD_SCHEDULED_BUILD	Whether the build is triggered by scheduler(true) or not(false)
SD_DIND_SHARE_PATH	Path to shared directory between build container and DinD container when Docker-in-Docker feature is enabled
CONTAINER_IMAGE	Build container image. Available when Kubernetes is used as build executor
CONTAINER_CPU_LIMIT	Value of CPU allocated to build container
CONTAINER_MEMORY_LIMIT	Value of memory allocated to build container

User configurable

Name	Default Value	Description
SD_ZIP_ARTIFACTS	false	Options: (`true`/`false`) Compresses and uploads artifacts in a single ZIP file. Use case: Reduces upload time when your build has a lot of artifacts. If the upload fails, it’s likely that the zip is too larger to handle. Note: Consult with your cluster admin to see if this option is available.
USER_SHELL_BIN	sh	The user shell bin to run the build in. Can also be the full path such as `/bin/bash`. Example repo: https://github.com/screwdriver-cd-test/user-shell-example
GIT_RECURSIVE_CLONE	true	Options: (`true`/`false`) Clones submodule repositories recursively.
GIT_SHALLOW_CLONE	true	Options: (`true`/`false`) Shallow clones source repository.
GIT_SHALLOW_CLONE_DEPTH	50	Shallow clone with a history truncated to the specified number of commits
GIT_SHALLOW_CLONE_SINCE		Shallow clone with a history truncated starting from the specified datetime (inclusive). If set, this has priority over `GIT_SHALLOW_CLONE_DEPTH`. This uses `--shallow-since` which accepts both absolute dates (e.g.: `2019-04-01`) and relative dates (e.g.: `4 weeks ago`).
GIT_SHALLOW_CLONE_SINGLE_BRANCH		If set to `true`, it will use `--single-branch` option for shallow clone. Otherwise, `--no-single-branch` option is used.
SD_COVERAGE_PLUGIN_ENABLED	`true`	If set to string `false`, step `sd-teardown-screwdriver-coverage-bookend` will be skipped.

Plugins

These environment variables may or may not be available depending on what plugins are installed.

Coverage (Sonar)

Name	Description
SD_SONAR_AUTH_URL	Screwdriver API authentication URL that will return a Sonar access token
SD_SONAR_HOST	Sonar host URL
SD_SONAR_ENTERPRISE	Whether using Enterprise (true) or open source edition of SonarQube(false)
SD_SONAR_PROJECT_KEY	Sonar project key (e.g.: `pipeline:123` or `job:456`)
SD_SONAR_PROJECT_NAME	Sonar project name (e.g.: `d2lam/myPipeline` or `d2lam/myPipeline:main`)
SD_ALLOW_PRIVATE_COVERAGE_SEND	If set to the string `true`, private pipelines will also have the ability to send coverage data

Directories

Name	Description
SD_ARTIFACTS_DIR	Location of built/generated files. Note: The `sd-teardown-screwdriver-artifact-bookend` step uploads artifacts from this directory into the Store unless the build is `ABORTED`.
SD_META_DIR	Location of the metadata directory
SD_META_PATH	Location of the metadata file
SD_ROOT_DIR	Location of workspace (e.g.: `/sd/workspace`)
SD_SOURCE_DIR	Location of checked-out code (e.g.: `sd/workspace/src/github.com/d2lam/myPipeline`)
SD_SOURCE_PATH	Location of source path which triggered current build. See Source Paths.
SD_CONFIG_DIR	Location of parent pipeline’s repository (only set for child pipelines) (e.g.: `sd/workspace/config`)

Environment Variables

Name	Description
<environment_variable>	Environment variable specified under the “environment” section in your screwdriver.yaml

Please be aware if you are using dot notations in the environment variables, like:

environment:
   REGION.INSTANCE: 'xyz'

Then process.env.REGION.INSTANCE won’t work, and you must use process.env['REGION.INSTANCE'] dot notation to access as well.

Source Code

Name	Description
SCM_URL	SCM URL that was checked out (e.g.: `https://github.com/d2lam/myPipeline`)
GIT_URL	SCM URL that was checked out with .git appended (e.g.: `https://github.com/d2lam/myPipeline.git`)
CONFIG_URL	SCM URL of the parent pipeline repository (only set for child pipelines)
GIT_BRANCH	Reference for PR or the branch (e.g.: `origin/refs/${PRREF}` or `origin/${BRANCH}`)
PR_BASE_BRANCH_NAME	Base branch name the PR is opened against (e.g.: `${BRANCH}`)
PR_BRANCH_NAME	Branch name of the PR (e.g.: `origin/${BRANCH}` or `upstream/${BRANCH}`)
