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

    yum install epel-release python-pip
    yum install -y python-devel libffi-devel openssl-devel gcc
    pip install -U pip
  2. 修改docker启动文件

    # 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
    EOF
  3. 重启docker

    systemctl daemon-reload
    systemctl restart docker
  4. 安装docker的python库

    shellyum install python-docker-py
    or
    pip install -U docker-py
  5. 配置时间同步(此处略)
  6. 禁用libvirt

    systemctl stop libvirtd.service
    systemctl disable libvirtd.service
  7. 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。

    pip install -U ansible==1.9.4
  8. 安装stable版kolla
  • 下载源码

    git clone https://git.openstack.org/openstack/kolla -b stable/mitaka
  • 安装依赖

    pip install -r kolla/requirements.txt -r kolla/test-requirements.txt
  • 源码安装

    pip install kolla/
  1. 安装tox,生成配置文件

    pip install -U tox
    cd kolla/
    tox -e genconfig
    cp -rv etc/kolla /etc/
  2. 安装python client

    yum install python-openstackclient python-neutronclient
  3. 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

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:

部署容器

  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。

    kolla-genpwd

    为了方便,我们修改其中的管理员登陆密码

    vim /etc/kolla/passwords.yml
    keystone_admin_password: admin
  2. 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

    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

    kolla-ansible prechecks
  4. 开始部署

    kolla-ansible deploy

    部署成功后查看容器

    # docker ps
    CONTAINER ID        IMAGE                                                 COMMAND                  CREATED             STATUS              PORTS               NAMES

  5. 修改虚拟化类型
    因为是在虚拟机中安装,不支持kvm,需要修改虚拟类型为qemu

    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
image

一些有用的工具

  1. 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):

    kolla-ansible post-deploy
  2. 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:

    source /etc/kolla/admin-openrc.sh
    kolla/tools/init-runonce
  3. 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:

    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

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:

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:
