前言
最近在私有云部署一套自動化運維平臺；
其中k8s是重頭戲，這篇文章為大家分享一下二進制安裝方式
k8s架構圖
安裝程序
-
基本環境
- CentOS版本 7.9.2009
- Etcd 版本3.4.14
- Docker
- k8s版本 1.17.16
-
kube-apiserver服務安裝
- 下載并解壓
cd /soft
wget https://dl.k8s.io/v1.20.0/kubernetes-server-linux-amd64.tar.gz
tar -zxvf kubernetes-server-linux-amd64.tar.gz
cd kubernetes
- 創建啟動組態檔
mkdir /soft/kubernetes/server/conf/
vim /soft/kubernetes/server/conf/apiserver
KUBE_API_ADDRESS="--insecure-bind-address=0.0.0.0"
KUBE_API_PORT="--port=8886"
KUBE_ETCD_SERVERS="--etcd-servers=http://10.9.0.46:2379"
KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=169.169.0.0/16"
KUBE_ADMISSION_CONTROL="--admission-control=NamespaceLifecycle,LimitRanger,SecurityContextDeny,ResourceQuota"
KUBE_API_LOG="--logtostderr=false --log-dir=/home/k8s-t/log/kubernets --v=2"
KUBE_API_ARGS=" "
- 修改組態檔
vim /etc/systemd/system/kube-apiserver.service
[Unit]
Description=Kubernetes API Server
After=etcd.service
Wants=etcd.service
[Service]
EnvironmentFile=/soft/kubernetes/server/conf/apiserver
ExecStart=/soft/kubernetes/server/bin/kube-apiserver \
$KUBE_ETCD_SERVERS \
$KUBE_API_ADDRESS \
$KUBE_API_PORT \
$KUBE_SERVICE_ADDRESSES \
$KUBE_ADMISSION_CONTROL \
$KUBE_API_LOG \
$KUBE_API_ARGS
Restart=on-failure
Type=notify
LimitNOFILE=65536
[Install]
WantedBy=multi-user.target
- kube-controller-manger服務安裝
- 創建啟動組態檔
vim /soft/kubernetes/server/conf/controller-manager
KUBE_MASTER="--master=http://10.9.0.46:8886"
KUBE_CONTROLLER_MANAGER_ARGS=" "
- 修改組態檔
vim /etc/systemd/system/kube-controller-manager.service
[Unit]
Description=Kubernetes Scheduler
After=kube-apiserver.service
Requires=kube-apiserver.service
[Service]
EnvironmentFile=-/soft/kubernetes/server/conf/controller-manager
ExecStart=/soft/kubernetes/server/bin/kube-controller-manager \
$KUBE_MASTER \
$KUBE_CONTROLLER_MANAGER_ARGS
Restart=on-failure
LimitNOFILE=65536
[Install]
WantedBy=multi-user.target
- kube-scheduler服務安裝
- 創建啟動組態檔
vim /soft/kubernetes/server/conf/scheduler
KUBE_MASTER="--master=http://10.9.0.46:8886"
KUBE_SCHEDULER_ARGS="--logtostderr=true --log-dir=/home/k8s-t/log/kubernetes --v=2"
- 創建服務組態檔
vim /etc/systemd/system/kube-scheduler.service
[Unit]
Description=Kubernetes Scheduler
After=kube-apiserver.service
Requires=kube-apiserver.service
[Service]
User=root
EnvironmentFile=-/soft/kubernetes/server/conf/scheduler
ExecStart=/soft/kubernetes/server/bin/kube-scheduler \
$KUBE_MASTER \
$KUBE_SCHEDULER_ARGS
Restart=on-failure
LimitNOFILE=65536
[Install]
WantedBy=multi-user.target
- 將各個組件啟動
systemctl daemon-reload
systemctl enable kube-apiserver.service
systemctl start kube-apiserver.service
systemctl enable kube-controller-manager.service
systemctl start kube-controller-manager.service
systemctl enable kube-scheduler.service
systemctl start kube-scheduler.service
總結
-
k8s改變了專案運維的方式，使得發布變得十分簡單的同時降低了專案風險；
-
多動手多實踐；
