Check the new build/commit being deployed is on the master branch:

bundle exec exe/check-branch-protection -r ${artifact.source.repositoryName} -e ${env.name} -b ${artifact.buildNo}

(Branch name etc can be changed, see --help for more options.)

Using a Git tag indicating the last deployment, check that the new commit being deployed is a descendant of the current commit:

bundle exec exe/check-forward-deploy -r ${artifact.source.repositoryName} -e ${env.name} -b ${artifact.buildNo}

(Tag prefix etc can be changed, see --help for more options.)

Using Git tags indicating recent deployments, check the commit being deployed is one of the last X commits or newer. Allows a user to rollback by X deployments.

bundle exec exe/check-recent-deploy -r ${artifact.source.repositoryName} -e ${env.name} -b ${artifact.buildNo}

(Allowed rollback count and tag prefix etc can be changed, see --help for more options.)

Check the current time is within the deployment window of Mon-Thu 9am to 4pm, or Fri 9am to 12pm, using local London time.

bundle exec exe/check-schedule

Creates a Git tag in the project repository to indicate the deployment has happened:

bundle exec exe/create-deployment-tag -r ${artifact.source.repositoryName} -e ${env.name} -b ${artifact.buildNo}

(Tagger's name and email address etc can be changed, see --help for more options.)
