Kolla overview:
Kolla is a project for automated deployment under OpenStack. It is implemented based on docker and ansible. Docker is mainly responsible for image production and container management, and ansible is mainly responsible for environment deployment and management. Kolla is actually divided into two parts: the kolla part provides a production environment level image, covering various services used by OpenStack; The kolla ansible section provides automated deployment. At the beginning, these two parts are in a project (i.e. kolla). OpenStack has been separated from the version beginning with O. only then can there be a kolla project for building all service images and kolla ansible for automatic deployment.
Environment configuration:
Minimum server configuration:
2 network interfaces
8GB main memory
40GB disk space
Centos 8.2
preparation:
Install basic system tools;
yum -y install net-tools vim wget bash-completion lrzsz
Turn off Slinux and firewall
setenforce 0 vim /etc/selinux/config take SELINUX=enforcing Change to SELINUX=disabled systemctl stop firewalld && systemctl disable firewalld && systemctl status firewalld
Modify hosts
vim /etc/hosts 192.168.6.35 node1
Network card configuration information
| ip address | network card | Network type | explain |
| 192.168.6.35 | eno16780032 | bridge | Openstack internal management network and Horizon web interface access; |
| None (address configuration is not required, and the network card needs to be turned on) | eno33559296 | bridge | External network is used by BR ex binding of neutron (network component in Openstack). The virtual machine in Openstack communicates with the external network through this network card. |

Deploy kolla ansible
1) Deploy
pip install ansible #Deploy Ansible note: Ansible should be greater than version 2.6 pip install kolla-ansible #Installing kolla ansible using pip
2) Copy the relevant configuration files of kolla ansible
cp -r /usr/share/kolla-ansible/etc_examples/kolla /etc/ cp /usr/share/kolla-ansible/ansible/inventory/* /etc/kolla/ [root@node1 ~]# ls /etc/kolla/ all-in-one globals.yml multinode passwords.yml
File Description: all in one is an ansible automatic installation configuration file for installing single node OpenStack; multinode is an ansible automatic installation configuration file for installing multi node OpenStack; globals.yml is a custom configuration file for OpenStack deployment; passwords.yml is the password file of each service in OpenStack.
2) Edit the configuration file of kolla ansible, which is used to customize the installation of OpenStack, generate the password file of each service of OpenStack, and modify the login password of the Web page.
kolla-genpwd vim /etc/kolla/passwords.yml //Change line 165, which is the password to log in to the Dashboard (web interface console). Under normal circumstances, it can not be too simple. You can intercept an automatically generated password keystone_admin_password: hsh.2019#
Edit / etc / kolla / global YML customize deployment matters in OpenStack
vim /etc/kolla/globals.yml //In lines 14 and 15, select the downloaded basic image and choose 1 from 5 # Valid options are ['centos', 'debian', 'oraclelinux', 'rhel', 'ubuntu'] kolla_base_distro: "centos" //Lines 17 and 18, select the installation method, 1 out of 2. binary installation, source source installation # Valid options are [ binary, source ] kolla_install_type: "source" //In lines 20 and 21, select the version label of OpenStack. For details, see: https://releases.openstack.org/ # Valid option is Docker repository tag openstack_release: "stein" //Note that the version must be lowercase, and the docker image label related to OpenStack downloaded later is also stein.

4, Installing OpenStack private cloud based on kolla ansible
Configure the / etc / kolla / all in one file
//Modify lines 3 to 19 and change "localhost; ansible_connection=local" to "node1"
//You can use the replacement command: ":% s/localhost; ansible_connection=local/node1/g"

Start deploying OpenStack. Note: when I use Alibaba cloud's epel source, I get stuck in the task [baremetal: install Yum packages] step when installing bootstrap server. The epel source installed in the system only waited about 5 minutes.

Error 1: failed to pull the image.
First, repeat the pull image operation several times. If it still fails, check / etc / kolla / global Whether the version number on line 21 in YML is correct. If the version number is correct, an error is still reported when you pull the image again, then go back one version and try to pull the image. (I just can't use the train version. Return to the stein version or use the queens version) pay attention to cleaning up the images of other versions
