kolla项目是为了容器化openstack，目标是做到100个节点的开箱即用，所有的组件的HA都具备。kolla是一个革命性的项目，我们以前积累的安装部署经验，全部都报废。使用kolla可以快速部署可扩展，可靠的生产就绪的openstack环境。
基本环境
操作系统：CentOS Linux release 7.2.1511 (Core) 内核版本：3.10.0-327.28.3.el7.x86_64 docker版本：Docker version 1.12.1, build 23cf638
部署kolla
1. 安装依赖
复制
yum install epel-release python-pip
yum install -y python-devel libffi-devel openssl-devel gcc
pip install -U pip2. 修改docker启动文件
复制
# Create the drop-in unit directory for docker.service
mkdir -p /etc/systemd/system/docker.service.d
# Create the drop-in unit file
tee /etc/systemd/system/docker.service.d/kolla.conf <<-'EOF'
[Service]
MountFlags=shared
EOF3. 重启docker
复制
systemctl daemon-reload
systemctl restart docker4. 安装docker的python库
复制
yum install python-docker-py
or
pip install -U docker-py5. 配置时间同步（此处略）
6. 禁用libvirt
复制
systemctl stop libvirtd.service
systemctl disable libvirtd.service7. 安装ansible
这里需要注意的是如果安装stable版的kolla需要Ansible < 2.0，master版需要Ansible > 2.0。默认yum安装ansible版本>2.0，因为我要安装stable/mitaka版，所有指定安装版本。
复制
pip install -U ansible==1.9.48. 安装stable版kolla
- 下载源码 复制
git clone https://git.openstack.org/openstack/kolla -b stable/mitaka- 安装依赖 复制
pip install -r kolla/requirements.txt -r kolla/test-requirements.txt- 源码安装 复制
pip install kolla/9. 安装tox，生成配置文件
复制
pip install -U tox
cd kolla/
tox -e genconfig
cp -rv etc/kolla /etc/10. 安装python client
复制
yum install python-openstackclient python-neutronclient11. 本地docker仓库
all-in-one环境中本地仓库不是必须的这里没有配置
编译镜像
复制
kolla-build更多的编译选项可以参看：Building Container Images 如果个别镜像编译失败可以重新执行以上操作，因为docker的容器缓存，重新编译会很快 编译成功后生成的镜像如下所示：
复制
# docker images

1. 生成密码
openstack环境的密码等变量可以在 /etc/kolla/passwords.yml 中指定，为了方便可以使用kolla-genpwd工具自动生成复杂密码。
复制
kolla-genpwd为了方便，我们修改其中的管理员登陆密码
复制
vim /etc/kolla/passwords.yml
keystone_admin_password: admin2. 修改部署配置文件
修改/etc/kolla/globals.yml 文件，指定部署的一些信息
复制
vim /etc/kolla/globals.yml
kolla_base_distro: "centos"
kolla_install_type: "binary"
enable_haproxy: "no"
#kolla_internal_vip_address: "10.10.10.254"
kolla_internal_address: "192.168.2.120"
network_interface: "ens160"
neutron_external_interface: "ens192"
neutron_plugin_agent: "openvswitch"
openstack_logging_debug: "True"3. 检查配置
复制
kolla-ansible prechecks4. 开始部署
复制
kolla-ansible deploy5. 部署成功后查看容器
复制

因为是在虚拟机中安装，不支持kvm，需要修改虚拟类型为qemu
复制
vim /etc/kolla/nova-compute/nova.conf
[libvirt]
...
virt_type=qemu然后就可以通过 kolla_internal_address 访问openstack环境

一些有用的工具
- 部署完成后，运行以下命令可以生成一个openrc文件(运行openstack CLI所需的环境变量): 复制
kolla-ansible post-deploy- openrc文件生成之后，使用以下命令可以帮你做一下openstack的初始化工作，包括上传一个glance镜像以及创建几个虚拟网络: 复制
source /etc/kolla/admin-openrc.sh
kolla/tools/init-runonce- 由于错误的出现，可能需要多次的部署，而有些错误重新部署是不会进行修正的，所以需要将整个环境进行清理: 复制
tools/cleanup-containers #可用于从系统中移除部署的容器
tools/cleanup-host #可用于移除由于残余网络变化引发的docker启动的neutron-agents主机
tools/cleanup-images #可用于从本地缓存中移除所有的docker image日志查看
kolla通过heka容器来收集所有容器的日志
复制
docker exec -it heka bash所有的容器都可以从这个目录中获取服务日志：/var/log/kolla/SERVICE_NAME。 如果需要输出日志，请运行：
复制
docker logs大多数容器不会stdout，上面的命令将不会提供信息。
出错处理
deploy时遇到以下错误:
