分布式搭建

ansible安装

安装ansible

pip install virtualenv
virtualenv --no-site-packages venv
source venv/bin/active
pip install ansbile

ansbile主机配置

[test]
127.0.0.1 ansible_ssh_user=aaa ansible_ssh_port=22 ansible_ssh_pass=aaa

注释这么配置不好，但初始这样配置，为了之后批量分发，分发后请删除这个账户

ansbile批量推送公钥

ssh-keygen
 ansible-playbook   -i hosts   ssh.yml

推送文件ssh.yml

# Using alternate directory locations:
 - hosts: test
   user: aaa
   tasks:
    - name: ssh-copy
      authorized_key: user=aaa key="{{ lookup('file', '/home/aaa/.ssh/id_rsa.pub') }}"
      tags:
        - sshkey

执行代码

ansible  test -i ./hosts  -m command -a "echo 'aa'"

k8s安装（需要翻墙）

apt-get update && apt-get install -y apt-transport-https curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
deb https://apt.kubernetes.io/ kubernetes-xenial main
EOF
apt-get update
apt-get install -y kubelet kubeadm kubectl kubernetes-cni docker.io 
apt-mark hold kubelet kubeadm kubectl

配置文件

apiVersion: kubeadm.k8s.io/v1alpha2
kind: MasterConfiguration
api:
  advertiseAddress: 0.0.0.0
networking:
  podSubnet: 10.244.0.0/16
etcd:
  image: registry.cn-hangzhou.aliyuncs.com/google_containers/etcd-amd64:3.1.11
kubernetesVersion: v1.12.1
imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers

imageRepository: registry.cn-hangzhou.aliyuncs.com/google_containers

sudo swapoff -a
　1. 为docker服务创建一个内嵌的systemd目录

$ mkdir -p /etc/systemd/system/docker.service.d

　　2. 创建/etc/systemd/system/docker.service.d/http-proxy.conf文件，并添加HTTP_PROXY环境变量。其中[proxy-addr]和[proxy-port]分别改成实际情况的代理地址和端口：
　　
[Service]
Environment="HTTP_PROXY=http://[proxy-addr]:[proxy-port]/" "HTTPS_PROXY=http://[proxy-addr]:[proxy-port]/"
$ systemctl daemon-reload
$ systemctl restart docker
sudo kubeadm init --config ./kubeadm.conf

sudo kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/k8s-manifests/kube-flannel-legacy.yml
需要安装flannel
