Image building
|
|
==============
|
|
|
|
The ``tools/build.py`` script in this repository is
|
|
responsible for building docker images.
|
|
|
|
Guide
|
|
-----
|
|
|
|
In general, you will build images like this:
|
|
|
|
::
|
|
|
|
$ tools/build.py
|
|
|
|
By default, the above command would build all images based on centos image.
|
|
|
|
If you want to change the base distro image, add ``-b``:
|
|
|
|
::
|
|
|
|
$ tools/build.py -b ubuntu
|
|
|
|
There are following distros available for building images:
|
|
|
|
- fedora
|
|
- centos
|
|
- oraclelinux
|
|
- ubuntu
|
|
|
|
To push the image after building, add ``--push``:
|
|
|
|
::
|
|
|
|
$ tools/build.py --push
|
|
|
|
|
|
If you want to build only keystone image, use the following command:
|
|
|
|
::
|
|
|
|
$ tools/build.py keystone
|
|
|
|
|
|
If you want to build multiple images e.g. keystone and nova, use the following command:
|
|
|
|
::
|
|
|
|
$ tools/build.py keystone nova
|
|
|
|
|
|
``tools/build.py`` use ``kollaglue`` as default namespace. If you
|
|
want to push images to your dockerhub, change the namespace like:
|
|
|
|
::
|
|
|
|
$ tools/build.py -n yourusername --push
|
|
|
|
|
|
Build Openstack from Source
|
|
---------------------------
|
|
|
|
When building images, there are two methods of the Openstack install.
|
|
One is ``binary``. Another is ``source``.
|
|
The ``binary`` means that Openstack will be installed from apt/yum.
|
|
And the ``source`` means that Openstack will be installed from source code.
|
|
The default method of the Openstack install is ``binary``.
|
|
You can change it to ``source`` using the following command:
|
|
|
|
::
|
|
|
|
tools/build.py -t source
|
|
|
|
The locations of Opentack source code are written in ``build.ini``.
|
|
Now the source type support ``url`` and ``git``. The ``build.ini`` looks like:
|
|
|
|
::
|
|
|
|
[glance-base]
|
|
type = url
|
|
location = http://tarballs.openstack.org/glance/glance-master.tar.gz
|
|
|
|
[keystone]
|
|
type = git
|
|
location = https://github.com/openstack/keystone
|
|
reference = stable/kilo
|
|
|
|
To build RHEL containers, it is necessary to use the -i (include header)
|
|
feature to include registration with RHN of the container runtime operating
|
|
system. To obtain a RHN username/password/pool id, contact Red Hat.
|
|
|
|
First create a file called rhel-include:
|
|
|
|
::
|
|
|
|
RUN subscription-manager register --user=<user-name> --password=<password> \
|
|
&& subscription-manager attach --pool <pool-id>
|
|
|
|
Then build RHEL containers:
|
|
|
|
::
|
|
|
|
build -b rhel -i ./rhel-include
|
