kolla all-in-one 安装

http://docs.openstack.org/developer/kolla/

使用了Docker containers and Ansible playbooks

目前在Fedora/Ubuntu/CentOS上测试过

deployment host 需要Ansible>=1.8.4

deployment target 需要docker>=1.7.0 and docker-py>=1.2.0

curl -sSL https://get.docker.io | bash

git clone https://git.openstack.org/openstack/kolla

cd kolla

sudo pip install -r requirements.txt

如果ansible版本太老可以：

pip install -U ansible

配置kolla的ansible

http://docs.openstack.org/developer/kolla/ansible-deployment.html

inventory 文件必须包含所有安装targets

在deployment host上，拷贝etc/kolla 到 /etc/kolla

kolla_external_address: "openstack.example.com"

kolla_internal_address: "10.10.10.254"

kolla_external_address和kolla_internal_address可以相同，

network_interface: "eth0"

服务绑定接口，

neutron_external_interface: "eth1"

连接neutron的external bridge，

如果机器只有一个接口，可以可以创建一个bridge和veth，把veth的一端作为这里的接口，另一端和eth0接到该bridge上。

docker_pull_policy: "always"

是否从指定的repository拉去image，

好啦，如果是all-in-one的部署方式，则所有的containers 都会运行在localhost本机。

cd ./kolla/ansible

ansible-playbook -i inventory/all-in-one -e @/etc/kolla/globals.yml -e @/etc/kolla/passwords.yml site.yml

如果想安装某个特定的服务，可以用Ansible tags

cd ./kolla/ansible

ansible-playbook -i inventory/all-in-one -e @/etc/kolla/globals.yml -e @/etc/kolla/passwords.yml site.yml --tags rabbitmq

ansible-playbook -i inventory/all-in-one -e @/etc/kolla/globals.yml -e @/etc/kolla/passwords.yml site.yml --tags rabbitmq,mariadb

https://registry.hub.docker.com/repos/kollaglue

对每个tagged release都有build的image

-  Cinder

ansible进阶小技巧(1)--tags

ansible role

ansilbe自1.2版本引入的新特性，用于层次性、结构化地组织playbook。roles能够根据层次型结构自动装载变量文件、tasks以及handlers等。要使用roles只需要在playbook中使用include指令即可。简单来讲，roles就是通过分别将变量、文件、任务、模块及处理器放置于单独的目录中，并可以便捷地include它们的一种机制。角色一般用于基于主机构建服务的场景中，但也可以是用于构建守护进程等场景中。

#创建role的步骤

(1) 创建以roles命名的目录；

(2) 在roles目录中分别创建以各角色名称命名的目录，如webservers等；

(3) 在每个角色命名的目录中分别创建files、handlers、meta、tasks、templates和vars目录；用不

到的目录可以创建为空目录，也可以不创建；

(4) 在playbook文件中，调用各角色；

#role内各目录中可用的文件

tasks目录：至少应该包含一个名为main.yml的文件，其定义了此角色的任务列表；此文件可以使用in

clude包含其它的位于此目录中的task文件；

files目录：存放由copy或script等模块调用的文件；

templates目录：template模块会自动在此目录中寻找Jinja2模板文件；

handlers目录：此目录中应当包含一个main.yml文件，用于定义此角色用到的各handler；在handler

中使用include包含的其它的handler文件也应该位于此目录中；

vars目录：应当包含一个main.yml文件，用于定义此角色用到的变量；

meta目录：应当包含一个main.yml文件，用于定义此角色的特殊设定及其依赖关系；

default目录：为当前角色设定默认变量时使用此目录；应当包含一个main.yml文件；
