Quickstart guide with kolla-ansible (for rocky)
Posted on Fri 15 February 2019 in openstack • 2 min read
Requirements
kolla-ansible(testet with 7.0.1)ansible(testet with 2.6.13)- epel-release (for centos)
python-pip
And some magic:
- vagrant
- vagrant-libvirt plugin
- vagrant config
Quickstart
We will run all commands on our admin-node (vagrant ssh kolla-admin)
sudo yum install -y epel-release
sudo yum install -y python2-pip
sudo pip install kolla-ansible==7.0.1
sudo pip install ansible==2.6.13
sudo cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/
sudo chown -R vagrant:vagrant /etc/kolla/
cp /usr/share/kolla-ansible/ansible/inventory/all-in-one ~/inventory
For ubuntu 16.04 :
sudo apt install python-pip
sudo cp -r /usr/local/share/kolla-ansible/etc_examples/kolla /etc/
Generate $random passwords with
kolla-genpwd
and maybe you want to change the keystone_admin_password password (this is your admin pass for the dashboard)
grep keystone_admin /etc/kolla/passwords.yml
keystone_admin_password: G26xkBrfltvrOk4rsG6MvAZFI418mrV5pgaSI9hm

$ kolla-ansible -i ~/inventory pull
$ kolla-ansible -i ~/inventory prechecks
$ kolla-ansible -i ~/inventory deploy

On the kolla-admin node
$ sudo yum install -y docker
$ sudo systemctl enable docker
$ sudo systemctl start docker
$ sudo pip install docker-compose
$ sudo mkdir /{srv,opt}/registry
$ sudo chown vagrant:vagrant /opt/registry
$ sudo setenforce 0
$ cat /opt/registry/config.yml

Configure the registry in kolla
$ grep "^docker_registry" /etc/kolla/globals.yml
docker_registry: "10.20.30.31:5000"
Rerun the bootstrap (kolla-ansible will configure the registry for you)
$ time kolla-ansible -i ~/inventory pull --forks=1
