Unblocker environment variables

Posted February 25, 2019 by Samuel

Block steps record the person who unblocks them, and this information is available to subsequent steps via $BUILDKITE_UNBLOCKER environment variables. ๐Ÿ‘ฎโ€โ™‚๏ธ

List of unblocker environment variables from the documentation linked earlier

Due to a quirk in our job environment calculations, these variables were only available in steps that were pipeline uploaded after the block step. This has been fixed, so now all steps after a block step will have the correct unblocker environment variables, no matter how theyโ€™re defined or uploaded. ๐Ÿ’ฏ

So if you upload a deployment pipeline like this: ๐Ÿ’โ€โ™€๏ธ

Deployment pipeline with block step still blocked and a subsequent waiting command job

The $BUILDKITE_UNBLOCKER environment variables will be set to the person who presses the Deploy button: ๐Ÿ™‹โ€โ™€๏ธ

Block step which has been unblocked and a completely command job with the unblocker's name

You can read more about block steps in our documentation. ๐Ÿ“š
