Customizing the Installer

You can modify the following installer scripts and files under /var/jenkins_home/docker-build and /var/jenkins_home/docker-deploy to build the Docker images.

docker-build

This directory contains the Docker files, as well as build and installation scripts for each TML component.

  • build.sh: This is the primary script used to build all the tml-components. This build.sh script internally calls the individual component's Docker image builder script build -<tml_component_type>.sh. under tmgc-<tml_component_type>.

  • build-<tml_component_type>.sh: This script is used to build the docker image for the given tml_component_type. This script internally uses Dockerfile.<tml_component_type>, create_<tml_component_type>.sh and files under the install folder for installing the required software/resources.
  • Dockerfile.<tml_component_type>: This contains the information on how to create/add users and groups, environment variables, expose ports. This file internally calls the <tml_component_type>-install.sh to install the required software.
  • create_<tml_component_type>.sh: This script finally builds the Docker image by using the information provided in Dockerfile.<tml_component_type>.
  • install: This directory contains the scripts for installing the required software, configuration files required for the software installation, logback configs and readiness probes.
