Deploy OpenStack all in one node using Ansible

Deploy OpenStack to ubuntu host(ubuntu docker image)

The machine minimal requirements:

• two network interfaces.

The machine recommended requirements:

• two network interfaces.
• more than 8gb main memory.
• at least 40gb disk space.

To verify the Ubuntu kernel is sufficient to operate Kolla, run the command:

docker run -i -t --net=host ubuntu su

If the command displays "su: System error", the system suffers from this DockerBug. This is a possible way to solve the issue:

sudo apt-get install linux-image-generic-lts-vivid
sudo reboot

The guide assumes that you have build images using the following command.

tools/build.py -n 172.22.2.81:4000/kollaglue --base ubuntu --type source --push

The IP, "172.22.2.81", is the host running private docker registry. To deploy a private docker registry, please read the document DeployingRegistryServer.

First, add --insecure-registry 172.22.2.81:4000 to DOCKER_OPTS in /etc/default/docker. And restart the docker service. This will permit Docker to pull from the deployment's private registry.

Clone the kolla repository and copy kolla config to "/etc":

git clone https://github.com/openstack/kolla
cd kolla
cp -rf etc/kolla/ /etc/

And modify the file, "/etc/kolla/globals.yml". Do the below tasks.

• Set "kolla_base_distro" to "ubuntu".
• Set "kolla_install_type" to "source".
• Set "docker_registry" to "172.22.2.81:4000".
• Change kolla_internal_address value. Specify an unisued IP address in the deployment environment

Change the following values if needed:

• network_interface
• neutron_external_interface

After doing these tasks, run the following command in kolla directory:

tools/kolla-ansible -i ansible/inventory/all-in-one -p ansible/site.yml deploy

Deployment takes between 10 and 15 minutes from a local private registry on gigabit networks.
