# This Dockerfile is used for building container images to
# use as Jenkins Slaves for Nordix Infra. The image is configured
# and tested for running
#   - Jenkins Job Builder Verify and Merge jobs using tox
#   - ONAP report generation
#
# The image built using this Dockerfile is currently being stored on Nordix registry
# with the name nordixorg/infra-tools-docker-slave-ubuntu1804 which can be seen
# using the link below.
#   https://registry.nordix.org/harbor/projects/29/repositories/infra-tools-docker-slave-ubuntu1804
# The images are automatically attached to Jenkins as slaves using Jenkins
# Docker plugin with a name that looks like infra-ubuntu1804-<random_characters>
#
# In order to use this image as slave for your jobs, you need to use label
# infra-tools-docker-slave-ubuntu1804 so Jenkins schedules your job on this slave
# which gets provisioned by Jenkins Docker plugin. Please note that it takes few
# seconds before the slave becomes ready and job starts running.
#-------------------------------------------------------------------------------
# Please use this docker file to build new Nordix docker slave image.
# Here are the steps required to build and upload the new image to Nordix registry
# 1. Login to Nordix Harbor with account that have write access to nordixorg repository
#    $ docker login registry.nordix.org
# 2. Build new image using the correct path and tag version. For example:
#    $ docker build . -t "registry.nordix.org/nordixorg/infra-tools-docker-slave-ubuntu1804:5-jdk11"
# 3. Upload new image to Nordix registry
#    $ docker push registry.nordix.org/nordixorg/infra-tools-docker-slave-ubuntu1804:5-jdk11
