Boots Jenkins CI in Docker, and builds the current repo
|
|
|
|
- boots Jenkins container in Docker
|
|
- installs plugins
|
|
- prints admin credentials
|
|
- creates job from \$PWD/setup/jenkins-job.xml
|
|
- using pipeline from \$PWD/Jenkinsfile
|
|
- enables job
|
|
- builds job
|
|
- prints Jenkins UI URL and on Mac opens it in browser
|
|
|
|
${0##*/} [up]
|
|
|
|
${0##*/} down
|
|
|
|
${0##*/} ui - prints the Teamcity Server URL and on Mac automatically opens in browser
|
|
|
|
Idempotent, you can re-run this and continue from any stage
