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
|
|
|
|
The build script reads its configuration from ``/etc/kolla/kolla-build.conf``
|
|
or ``etc/kolla/kolla-build.conf``. This is where to change the default
|
|
settings.
|
|
|
|
|
|
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 OpenStack source code are written in
|
|
``etc/kolla/kolla-build.conf``.
|
|
Now the source type support ``url`` and ``git``. The
|
|
``etc/kolla/kolla-build.conf`` 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
|
|
|
|
|
|
|
|
Known issues
|
|
------------
|
|
|
|
|
|
1. Can't build base image because docker fails to install systemd.
|
|
|
|
|
|
There are some issue between docker and AUFS. The simple workaround
|
|
to avoid the issue is that add ``-s devicemapper`` to ``DOCKER_OPTS``.
|
|
Get more information about the issue from DockerBug_.
|
|
|
|
|
|
Setting up Docker local registry
|
|
--------------------------------
|
|
|
|
It is recommended to set up local registry for Kolla developers
|
|
or deploying multinode. The reason using a local registry is
|
|
deployment performance will operate at local network speeds,
|
|
typically gigabit networking. Beyond performance considerations,
|
|
the Operator would have full control over images that are deployed.
|
|
If there is no local registry, nodes pull images from Docker Hub
|
|
when images are not found in local caches.
|
|
|
|
Running Docker registry is easy. Just use the following command:
|
|
|
|
::
|
|
|
|
docker run -d -p 4000:5000 --restart=always --name registry registry
|
|
|
|
The default port of Docker registry is 5000.
|
|
But the 5000 port is also the port of keystone-api.
|
|
To avoid conflict, use 4000 port as Docker registry port.
|
|
|
|
Now the Docker registry service is running.
|
|
|
|
For docker to pull images, it is necessary to
|
|
modify the Docker configuration. The guide assumes that
|
|
the IP of the machine running Docker registry is 172.22.2.81.
|
|
|
|
In Ubuntu, add ``--insecure-registry 172.22.2.81:4000``
|
|
to ``DOCKER_OPTS`` in ``/etc/default/docker``.
|
|
|
|
In CentOS, uncomment ``INSECURE_REGISTRY`` and set ``INSECURE_REGISTRY``
|
|
to ``--insecure-registry 172.22.2.81:4000`` in ``/etc/sysconfig/docker``.
|
|
|
|
And restart the docker service.
|
|
|
|
To build and push images to local registry, use the following command:
|
|
|
|
::
|
|
|
|
tools/build.py --namespace 172.22.2.81:4000 --push
|
|
|
|
To make kolla-ansible pull images from local registry, set
|
|
``"docker_registry"`` to ``"172.22.2.81:4000"`` in
|
|
``"/etc/kolla/globals.yml"``.
