#支持 Ubuntu 18及以上的系統，CentOS7及CentOS8 系統
# k8s 版本 14，15，16，17 號版本

ansible 安裝

#Ubuntu  系列安裝
apt -y install ansible
#CentOS 8 安裝
dnf -y install ansible
# CentOS 7 安裝
yum -y install ansible
# 修改ansible 配置
## 說明id_rsa_storm1 私鑰名字請自行修改
sed -i 's/^#private_key_file =.*$/private_key_file =\/root\/.ssh\/id_rsa_storm1/g' /etc/ansible/ansible.cfg
sed -i 's/^#sudo_user      = root/sudo_user      = root/g' /etc/ansible/ansible.cfg
sed -i 's/^#remote_port    = 22/remote_port    = 22/g' /etc/ansible/ansible.cfg
sed -i 's/^#host_key_checking = False/host_key_checking = False/g' /etc/ansible/ansible.cfg
sed -i '/\[ssh_connection\]/a\ssh_args = -o ControlMaster=no' /etc/ansible/ansible.cfg

下載 CFSSL 二進制文件/或者自行編譯

# 配置CFSSL編譯環境 一點要在跨系統部署請在低版本下編譯會用到lib庫高版本編譯在低版本上運行要升級庫
#Ubuntu  系列安裝
apt -y install gcc git
#CentOS 8 安裝
dnf -y install gcc git 
# CentOS 7 安裝
yum -y install gcc git
# 配置go 編譯環境
# 下載go 語言
wget -P /usr/local/src/ https://dl.google.com/go/go1.12.14.linux-amd64.tar.gz
# 解壓 
tar -xf  /usr/local/src/go1.12.14.linux-amd64.tar.gz -C  /usr/local/
# 配置環境變量
cat << EOF |tee /etc/profile
export GOPATH=/root/go
export GOBIN=/root/go/bin
PATH=\$PATH:/usr/local/go/bin:\$HOME/bin:\$GOBIN
export PATH
EOF
# 生效環境變量
source /etc/profile
# 編譯 CFSSL
go get  github.com/cloudflare/cfssl/cmd/cfssl
go get  github.com/cloudflare/cfssl/cmd/cfssljson
#查看cfssl 是否安裝成功
cfssl  version 
# 已經編譯好的二進制文件 
wget -P  /tmp/ https://github.com/qist/lxcfs/releases/download/cfssl/cfssl.tar.gz
# 解壓下載好文件
 tar -xf /tmp/cfssl.tar.gz -C /usr/bin/
 # 刪除下載的壓縮包
 rm -rf  /tmp/cfssl.tar.gz

下載kubectl 可以是任意版本kubectl

wget -P  /tmp/ https://storage.googleapis.com/kubernetes-release/release/v1.14.10/kubernetes-client-linux-amd64.tar.gz
# 解壓
tar -xf /tmp/kubernetes-client-linux-amd64.tar.gz -C /tmp/
# cp 文件到/usr/bin
mv /tmp/kubernetes/client/bin/kubectl /usr/bin/
# 驗證是否能執行
kubectl version 
# 刪除 沒用文件
 rm -rf /tmp/kubernetes-client-linux-amd64.tar.gz
 rm -rf   /tmp/kubernetes

下載 ansible 一鍵生成腳本

cd /opt
git clone https://github.com/qist/k8s.git

以 kubernetes.v1.17 腳本爲例

準備下載使用的壓縮包文件腳本不做下載，github 外網速度越來越慢下載成功率不高所有采用手動下載方式進行下載

打開kubernetes.v1.17.sh 查看下載路徑 版本可以自行選擇
# 創建壓縮包存放目錄
mkdir /tmp/source
# 下載K8S 集羣所需壓縮包
#docker 下載
wget -P /tmp/source https://download.docker.com/linux/static/stable/x86_64/docker-19.03.5.tgz
#lxcfs 下載  
wget -P /tmp/source https://github.com/qist/lxcfs/releases/download/3.1.2/lxcfs-3.1.2.tar.gz
# cni 下載
wget -P /tmp/source https://github.com/containernetworking/plugins/releases/download/v0.8.3/cni-plugins-linux-amd64-v0.8.3.tgz
# etcd 下載
wget -P /tmp/source https://github.com/etcd-io/etcd/releases/download/v3.3.18/etcd-v3.3.18-linux-amd64.tar.gz
# 下載kubernetes server 壓縮包
wget -P /tmp/source https://storage.googleapis.com/kubernetes-release/release/v1.17.0/kubernetes-server-linux-amd64.tar.gz
# 下載haproxy 
wget -P /tmp/source https://www.haproxy.org/download/2.1/src/haproxy-2.1.1.tar.gz
# automake keepalived編譯用到
wget -P /tmp/source https://ftp.gnu.org/gnu/automake/automake-1.15.1.tar.gz
# 下載keepalived
wget -P /tmp/source https://www.keepalived.org/software/keepalived-2.0.19.tar.gz
# iptables centos7 及Ubuntu18號版本用到
wget -P /tmp/source https://www.netfilter.org/projects/iptables/files/iptables-1.6.2.tar.bz2

## 特別說明： keepalived 部署 必須單個部署 三節點部署
ansible-playbook -i 192.168.2.247, keepalived.yml -e IFACE=eth0  -e ROUTER_ID=HA1 -e HA1_ID=100 -e HA2_ID=110 -e HA3_ID=120 -e STATE_3=MASTER

# 安裝說明文件執行就OK  node 節點安裝ip 很多可以寫如文件例如：
vi node

192.168.2.167
192.168.2.189
192.168.2.196

192.168.2.248
192.168.2.249
192.168.2.250
192.168.2.251
192.168.2.252
192.168.2.253
# 執行

########## mkdir -p /root/.kube
##########複製admin kubeconfig 到root用戶作爲kubectl 工具默認密鑰文件

###################################################################################
##########  ansible 及ansible-playbook 單個ip ip結尾一點要添加“,”符號 ansible-playbook -i 192.168.0.1, xxx.yml
##########  source /opt/k8s/k8s.v17.0/environment.sh 設置環境變量生效方便後期新增證書等
##########  etcd 部署 ansible-playbook -i "192.168.2.247","192.168.2.248","192.168.2.249" etcd.yml
##########  etcd EVENTS 部署 ansible-playbook -i , events-etcd.yml
##########  kube-apiserver 部署 ansible-playbook -i "192.168.2.247","192.168.2.248","192.168.2.249", kube-apiserver.yml
##########  haproxy 部署 ansible-playbook -i "192.168.2.247","192.168.2.248","192.168.2.249", haproxy.yml
##########  keepalived 節點IP "192.168.2.247","192.168.2.248","192.168.2.249" 安裝keepalived使用IP 如果大於三個節點安裝keepalived 記得HA1_ID 唯一的也就是priority的值
##########  keepalived 也可以全部部署爲BACKUP STATE_x 可以使用默認值 IFACE 網卡名字默認eth0 ROUTER_ID 全局唯一ID   HA1_ID爲priority值
##########  keepalived 部署 節點1 ansible-playbook -i 節點ip1, keepalived.yml -e IFACE=eth0 -e ROUTER_ID=HA1 -e HA1_ID=100 -e HA2_ID=110 -e HA3_ID=120 -e STATE_3=MASTER
##########  keepalived 部署 節點2 ansible-playbook -i 節點ip2, keepalived.yml -e IFACE=eth0 -e ROUTER_ID=HA2 -e HA1_ID=110 -e HA2_ID=120 -e HA3_ID=100 -e STATE_2=MASTER
##########  keepalived 部署 節點3 ansible-playbook -i 節點ip3, keepalived.yml -e IFACE=eth0 -e ROUTER_ID=HA3 -e HA1_ID=120 -e HA2_ID=100 -e HA3_ID=110 -e STATE_1=MASTER

##########  提交授權到K8S集羣 kubectl apply -f /opt/k8s/k8s.v17.0/yaml/kubelet-bootstrap-rbac.yaml kubectl apply -f /opt/k8s/k8s.v17.0/yaml/kube-api-rbac.yaml
##########  系統版本爲centos7 或者 ubuntu18 請先升級 iptables ansible-playbook -i  要安裝node ip列表, iptables.yml
##########  安裝K8S node 使用kube-router ansible部署 ansible-playbook -i 要安裝node ip列表 package.yml lxcfs.yml docker.yml kubelet.yml
##########  安裝K8S node 使用 flannel 網絡插件ansible部署ansible-playbook -i 要安裝node ip列表 package.yml lxcfs.yml docker.yml kubelet.yml kube-proxy.yml
##########  部署自動掛載日期與lxcfs 到pod的 PodPreset  kubectl apply -f /opt/k8s/k8s.v17.0/yaml/allow-lxcfs-tz-env.yaml -n kube-system  " kube-system 命名空間名字"PodPreset 只是當前空間生效所以需要每個命名空間執行
##########  查看node 節點是否註冊到K8S kubectl get node kubectl get csr 如果有節點 kube-router 方式部署 kubectl apply -f /opt/k8s/k8s.v17.0/yaml/kube-router.yaml 等待容器部署完成查看node ip a | grep kube-bridge
##########  flannel 網絡插件部署 kubectl apply -f /opt/k8s/k8s.v17.0/yaml/flannel.yaml 等待容器部署完成查看node 節點網絡 ip a| grep flannel.1
##########  給 master ingress 添加污點 防止其它服務使用這些節點:kubectl taint nodes  k8s-master-01 node-role.kubernetes.io/master=:NoSchedule kubectl taint nodes  k8s-ingress-01 node-role.kubernetes.io/ingress=:NoSchedule
##########  calico 網絡插件部署 50節點內 wget https://docs.projectcalico.org/v3.10/manifests/calico.yaml  大於50節點 wget https://docs.projectcalico.org/v3.10/manifests/calico-typha.yaml
########## 如果cni配置沒放到默認路徑請創建軟鏈 ln -s /apps/cni/etc /etc/cni 同時修改yaml hostPath路徑 同時修改CALICO_IPV4POOL_CIDR 參數爲 10.80.0.0/12 CALICO_IPV4POOL_IPIP: Never 啓用bgp模式
##########  windows 證書訪問 openssl pkcs12 -export -inkey k8s-apiserver-admin-key.pem -in k8s_apiserver-admin.pem -out client.p12
########## kubectl proxy --port=8001 &  把kube-apiserver 端口映射成本地 8001 端口
########## 查看kubelet節點配置信息 NODE_NAME="k8s-node-04"; curl -sSL "http://localhost:8001/api/v1/nodes/${NODE_NAME}/proxy/configz" | jq '.kubeletconfig|.kind="KubeletConfiguration"|.apiVersion="kubelet.config.k8s.io/v1beta1"' > kubele
