kolla 用docker部署openstack 裸机！
一、安装好操作系统进行如下配置：
1.配置源：
加入docker 源
cat > /etc/yum.repos.d/docker.repo << EOF
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/$releasever/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
EOF安装EPEL源
yum install -y epel-release二、安装pip 并升级 pip
yum install python-pip
pip install -U pip
pip -V三、安装docker
yum install deltarpm -y
curl -sSL https://get.docker.io | bash注意：这个命令将安装docker最近的稳定版，但是请注意，Kolla发布不与docker同步，所以有些地方阻止新版本docker的工作，docker 版本要>=1.0.0,查看的命令为：
docker --version修改docker文件：这一步是必学要做的，否则在deploy的时候 会报错：
# 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重启docker：
systemctl daemon-reload
systemctl restart docker安装docker-python：
yum install python-docker-py
或者：
pip install -U docker-py 安装ntp
yum install -y ntp
systemctl enable ntpd.service
systemctl start ntpd.service关闭libvirt
systemctl stop libvirtd.service
systemctl disable libvirtd.service安装ansible ：
yum install -y ansible
或者：
pip install -U ansible （需要先安装依赖：“yum install -y python-devel libffi-devel git gcc python-setuptools openssl-devel”）安装kolla
安装kolla依赖：
yum install -y python-devel libffi-devel git gcc python-setuptools openssl-devel安装kolla：
pip install kolla
cp -r /usr/share/kolla/etc_examples/kolla /etc/
git clone https://git.openstack.org/openstack/kolla
pip install -r kolla/requirements.txt -r kolla/test-requirements.txt
cd kolla
cp -r etc/kolla /etc/安装python 客户端：
yum install python-devel libffi-devel openssl-devel gcc
yum install python-openstackclient python-neutronclient
或者
pip install -U python-openstackclient python-neutronclientbuild 镜像
pip install tox
tox -e genconfig
cp -rv etc/kolla /etc/
echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf ## 开启ipv4转发，不然build会报错 ！
sysctl -p
kolla-build --base centos --type source -p default参数中的 -p default 是指定了只 build 主要的 image, 包括 : mariadb, rabbitmq, cinder, ceilometer, glance, heat, horizon, keystone, neutron, nova, swift 等 . 这些可以只生成的 kolla-build.conf 里找到。
如果 Build 完成之后，使用 docker images 能看到所有已经 build 好的镜像。
安装（deploy）
依然是先修改配置文件，与 Deploy 相关的主要是两个配置文件 /etc/kolla/passwords.yml 和 /etc/kolla/globals.yml。他们为 ansible 提供一些变量的设定。主要需要修改的是 globals.yml 文件。修改后，其主要内容为 :
config_strategy: "COPY_ALWAYS"
kolla_base_distro: "centos"
kolla_install_type: "source"
kolla_internal_address: "10.2.0.254"
network_interface: "eth0"
neutron_external_interface: "eth1"
openstack_logging_debug: "true"
enable_cinder: "no"
enable_heat: "no"kolla 使用一个名为 kolla-ansible 的封装脚本， 并提供以下几个命令
./tools/kolla-ansible -h
Usage: ./tools/kolla-ansible COMMAND [options]
Options:
--inventory, -i Specify path to ansible inventory file
--playbook, -p Specify path to ansible playbook file
--keyfile, -k Specify path to ansible vault keyfile
--help, -h Show this usage information
--tags, -t Only run plays and tasks tagged with these values
Commands:
prechecks Do pre-deployment checks for hosts
deploy Deploy and start all kolla containers
post-deploy Do post deploy on deploy node
pull Pull all images for containers (only pulls, no runnnig container changes)可以使用 ./tools/kolla-ansible prechecks 来检查一个机器是否满足安装条件。
使用 ./tools/kolla-ansible deploy 来开始正式安装。安装会很快，我机器上，几分钟就安装完成了。
最后，使用 ./tools/kolla-ansible post-deploy 来生成 /etc/kolla/admin-openrc.sh 文件用来加载认证变量。

由于 kolla 使用的是 –net=host 网络，所以没有必要做端口映射
每个模块拆分成了多个 container, 如 nova 被拆分成了 nova_api, nova_libvirt, nova_conductor, nova_novncproxy, nova_compute 等多个 container。很好的遵守了一个容器一个进程的原则。
