[Developer Guide] Dockerfile Unification
The current building process involves a serie of steps that can be simplified in order to do the process/experience more user friendly for our end users: - Unification of Docker files into one allows to build base container via a single make call. - Remove the copy of git configuration file since it will be generated. Based on the unification to one Dockerfile, our Developer Guide new "flow" is: - Prepare Base Docker Image - Build "base image" - Build the CentOS Mirror Repository - Run container from "base image" - Get mirror files - Create StarlingX Packages - Run container from "base image" - Get StarlingX source code - Build StarlingX packages - Build StarlingX ISO Story: 2003712 Task: 28010 Change-Id: I5776a7c515a7f2f1f3355644092b1d0a913f1ee8 Signed-off-by: Abraham Arce <abraham.arce.moreno@intel.com>

Prepare the Base Docker Image
|

-----------------------------
|
||||
|
||||
StarlingX base docker image handles all steps related to StarlingX ISO
|
||||
creation. This section describes how to customize the base Docker image
|
||||
building process.
|
||||
|
||||
********************
|
||||
Configuration Values
|
||||
********************
|
||||
|
||||
You can customize values for the StarlingX base Docker image using a
|
||||
text-based configuration file named ``localrc``:
|
||||
|
||||
- ``HOST_PREFIX`` points to the directory that hosts the 'designer'
|
||||
subdirectory for source code, the 'loadbuild' subdirectory for
|
||||
the build environment, generated RPMs, and the ISO image.
|
||||
- ``HOST_MIRROR_DIR`` points to the directory that hosts the CentOS mirror
|
||||
repository.
|
||||
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
localrc Configuration File
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Create your ``localrc`` configuration file. For example:
|
||||
|
||||
.. code:: sh
|
||||
|
||||
# tbuilder localrc
|
||||
MYUNAME=$USER
|
||||
PROJECT=starlingx
|
||||
HOST_PREFIX=$HOME/starlingx/workspace
|
||||
HOST_MIRROR_DIR=$HOME/starlingx/mirror
|

|
||||
***************************

||||
Build the Base Docker Image
|
||||
***************************
|
||||
|
||||
Once the ``localrc`` configuration file has been customized, it is time
|
||||
to build the base Docker image.
|

|

Build the CentOS Mirror Repository
|

----------------------------------
|

|

The creation of the StarlingX ISO relies on a repository of RPM Binaries,
|
||||
RPM Sources, and Tar Compressed files. This section describes how to build
|
||||
this CentOS mirror repository.
|
||||
|
||||
*******************************

Run Repository Docker Container
|
||||
*******************************
|

|
||||
| Run the following commands under a terminal identified as "**One**":
|
||||
|
||||
#. Navigate to the *$HOME/stx-tools/centos-mirror-tool* project
|
||||
directory:
|
||||
|
||||
.. code:: sh
|
||||
|
||||
$ docker run -itd --name $USER-centos-mirror-repository --volume $(pwd):/localdisk $USER:centos-mirror-repository
|
||||
$ cd $HOME/stx-tools/centos-mirror-tools/
|
||||
|
||||
**NOTE**: The above command creates the container in the background.
|
||||
With the container running in the background, you must attach to it
|
||||
manually. An advantage of attaching to the container manually is that
|
||||
you can enter and exit from the container as many times as you want.
|
||||
#. Launch the Docker container using the previously created base Docker image
|
||||
*<repository>:<tag>*. As /localdisk is defined as the workdir of the
|
||||
container, you should use the same folder name to define the volume.
|
||||
The container starts to run and populate 'logs' and 'output' folders in
|
||||
this directory. The container runs from the same directory in which the
|
||||
scripts are stored.
