Note

• ✅ Using the Jenkins official docker repository image, Locale and Timezone are not Korea setting.
  https://hub.docker.com/r/jenkins/jenkins
• So I used https://hub.docker.com/r/leechungkyu/jenkins image.
  This is an image with Locale and Timezone related to Korea setting added to the existing official Dockerfile. Related Facebook Links
