Docker 1.7.0-dev is required to support cinder and neutron thin containers. It would also be helpful that we validate that Docker 1.7.0-dev is working well with Kolla. For more details on the Neutron thin containers check out: https://github.com/SamYaple/yaodu/blob/master/ansible/roles/docker_build/files/ubuntu/neutron/ip_wrapper.py Change-Id: Ie422185ea090090b35fcaa2e1c6ecab1c8ea326b

# Developer Environment
|
|
|
|
If you are developing Kolla on an existing OpenStack cloud
|
|
that supports Heat, then follow the Heat template [README][].
|
|
Otherwise, follow the instructions below to manually create
|
|
your Kolla development environment.
|
|
|
|
[README]: https://github.com/stackforge/kolla/blob/master/devenv/README.md
|
|
|
|
## Installing Dependencies
|
|
|
|
In order to run Kolla, it is mandatory to run a version of `docker-compose`
|
|
that includes pid: host support. The `docker-compose` master repository
|
|
includes support but the pip packaged version of 1.2.0 does not. We expect
|
|
the pip packaged version of docker-compose 1.3.0 to include the necessary
|
|
features, so these next steps won't be necessary if installed from pip or
|
|
distro packaging.
|
|
|
|
git clone http://github.com/docker/compose
|
|
cd compose
|
|
sudo pip install -e .
|
|
|
|
In order to run Kolla, it is mandatory to run a version of `docker`
|
|
that is 1.7.0-dev or later. Docker 1.5.0 has a defect in `--pid=host`
|
|
support where the libvirt container cannot be stopped. Docker 1.6.0 lacks
|
|
specific features needed by the master of Kolla. Docker 1.7.0-dev introduces
|
|
mount propogation which is necessary for Neutron thin containers
|
|
and bindmounting of the /dev filesystem which is mandatory for the cinder
|
|
container.
|
|
|
|
If a version of Docker less than 1.7.0-dev is running on your system, stop it:
|
|
|
|
sudo systemctl stop docker
|
|
sudo killall -9 docker
|
|
|
|
If using an RPM based system, use the Docker 1.7.0-dev RPMs provided by the
|
|
Fedora project:
|
|
|
|
sudo yum install https://kojipkgs.fedoraproject.org//packages/docker/1.7.0/6.git56481a3.fc23/x86_64/docker-1.7.0-6.git56481a3.fc23.x86_64.rpm
|
|
|
|
For Debian based systems, use the Docker installation tool provided by Docker,
|
|
Inc.:
|
|
|
|
curl -sSL https://test.docker.com/ | sh
|
|
|
|
For Ubuntu based systems, use the Docker installation tool provided by Docker,
|
|
Inc.:
|
|
|
|
curl -sSL https://test.docker.com/ubuntu | sh
|
|
|
|
Next, install the OpenStack python clients if they are not installed:
|
|
|
|
sudo yum install python-keystoneclient python-glanceclient \
|
|
python-novaclient python-heatclient python-neutronclient
|
|
|
|
Finally stop libvirt on the host machine. Only one copy of libvirt may be
|
|
running at a time.
|
|
|
|
service libvirtd stop
|
|
|
|
The basic starting environment will be created using `docker-compose`.
|
|
This environment will start up the openstack services listed in the
|
|
compose directory.
|
|
|
|
## Starting Kolla
|
|
|
|
To start, setup your environment variables.
|
|
|
|
$ cd kolla
|
|
$ ./tools/genenv
|
|
|
|
The `genenv` script will create a compose/openstack.env file
|
|
and an openrc file in your current directory. The openstack.env
|
|
file contains all of your initialized environment variables, which
|
|
you can edit for a different setup.
|
|
|
|
A mandatory step is customizing the FLAT_INTERFACE network interface
|
|
environment variable. The variable defaults to eth1. In some cases, the
|
|
second interface in a system may not be eth1, but a unique name. For
|
|
exmaple with an Intel driver, the interface is enp1s0. The interface name
|
|
can be determined by executing the ifconfig tool. The second interface must
|
|
be a real interface, not a virtual interface. Make certain to store the
|
|
interface name in `compose/openstack.env`:
|
|
|
|
NEUTRON_FLAT_NETWORK_INTERFACE=enp1s0
|
|
FLAT_INTERFACE=enp1s0
|
|
|
|
Next, run the start command:
|
|
|
|
$ sudo ./tools/kolla start
|
|
|
|
Finally, run the status command:
|
|
|
|
$ sudo ./tools/kolla status
|
|
|
|
This will display information about all Kolla containers.
|
|
|
|
## Debugging Kolla
|
|
|
|
All Docker commands should be run from the directory of the Docker binary,
|
|
by default this is `/`.
|
|
|
|
The `start` command to kolla is responsible for starting the containers
|
|
using `docker-compose -f <service-container> up -d`.
|
|
|
|
If you want to start a container set by hand use this template:
|
|
|
|
$ docker-compose -f glance-api-registry.yml up -d
|
|
|
|
|
|
You can determine a container's status by executing:
|
|
|
|
$ sudo ./docker ps -a
|
|
|
|
If any of the containers exited you can check the logs by executing:
|
|
|
|
$ sudo ./docker logs <container-id>
|
|
$ docker-compose logs <container-id>
|
|
|
|
If you want to start a individual service like `glance-api` manually, use
|
|
this template. This is a good method to test and troubleshoot an individual
|
|
container. Note some containers require special options. Reference the
|
|
compose yml specification for more details:
|
|
|
|
$ sudo ./docker run --name glance-api -d \
|
|
--net=host \
|
|
--env-file=compose/openstack.env \
|
|
kollaglue/fedora-rdo-glance-api:latest
