Tungsten Fabric知识库丨关于OpenStack、K8s、CentOS安装问题的补充
作者：Tatsuya Naganawa 译者：TF编译组
多kube-master部署
3个Tungsten Fabric控制器节点：m3.xlarge（4 vcpu）-> c3.4xlarge（16 vcpu）（由于schema-transformer需要cpu资源进行acl计算，因此我需要添加资源） 100 kube-master, 800 workers: m3.medium
在下面这个内容中，tf-controller安装和first-containers.yaml是相同的。更多详细内容，找TF中文社区。
Ami也相同（ami-3185744e），但是内核版本通过yum -y update kernel（转换为映像，并用于启动实例）更新
/tmp/aaa.pem是ec2实例中指定的密钥对
(在其中一个Tungsten Fabric控制器节点键入命令)yum -y install epel-release
yum -y install parallel

在OpenStack上嵌套安装Kubernetes
可以在all-in-one的openstack节点上尝试嵌套安装kubernetes。
在ansible-deployer安装了该节点之后，
此外，需要手动创建为vRouter TCP/9091连接本地服务
此配置将创建DNAT/SNAT，例如从src: 10.0.1.3:xxxx, dst-ip: 10.1.1.11:9091到src: compute's vhost0 ip:xxxx dst-ip: 127.0.0.1:9091，因此openstack VM中的CNI可以与计算节点上的vrouter-agent直接通信，并为容器选择端口/ip信息。
-
IP地址可以来自子网，也可以来自子网外部。
在该节点上，将创建两个Centos7（或ubuntu bionic）节点，并将使用相同的程序安装kubernetes集群，
当然yaml文件需要嵌套安装。
./resolve-manifest.sh contrail-nested-kubernetes.yaml > cni-tungsten-fabric.yaml
KUBEMANAGER_NESTED_MODE: "{{ KUBEMANAGER_NESTED_MODE }}" ## this needs to be "1"KUBERNESTES_NESTED_VROUTER_VIP: {{ KUBERNESTES_NESTED_VROUTER_VIP }} ## this parameter needs to be the same IP with the one defined in link-local service (such as 10.1.1.11)
如果coredns接收到ip，则说明嵌套安装正常。
vRouter ml2插件
我尝试了vRouter neutron插件的ml2功能。
使用AWS上的三个CentOS7.5（4 cpu，16 GB内存，30 GB磁盘，ami: ami-3185744e）。
随附基于本文件的步骤。

下附hosts、group_vars/all和patch的代码。（有些仅是错误修正，但有些会更改默认行为）

完成安装大约需要50分钟。
尽管/home/centos/devstack/openrc可以用于“demo”用户登录，但是需要管理员访问权限来指定其网络类型（vRouter为空，ovs为“vxlan”），因此需要手动创建adminrc。
