Triggers
There are a few great tricks for triggering and scheduling builds in the following snippets!
Skip Builds
By default, CircleCI automatically builds a project whenever you push changes to a version control system (VCS). You can override this behavior by adding a [ci skip] or [skip ci] tag anywhere in a commit’s title or description.
Trigger a Job Using curl and Your API Token
curl -u ${CIRCLE_API_USER_TOKEN}: \
-d build_parameters[CIRCLE_JOB]=deploy_docker \
