kubernetes 安裝     DATE: 2026-05-05 10:35:58

Kubernetes(簡(jiǎn)稱(chēng)K8s)是安裝一個(gè)開(kāi)源的容器編排平臺，用于自動(dòng)化部署、安裝擴展和管理容器化應用程序，安裝它允許開(kāi)發(fā)者在集群中輕松地部署、安裝擴展和管理容器化應用程序，安裝從而實(shí)現高可用(yong)性、安裝負載均衡和自動(dòng)擴縮容等功能，安裝本文將介紹如何使用kubeadm安裝Kubernetes實(shí)踐過(guò)程。安裝

準備工作

1、安裝系統環(huán)境要求

Kubernetes支持多種操作系(′?_?`)統，安裝包括Linux、安裝Windows(/ω＼)和macOS，安裝本文將以L(fǎng)inux為例進(jìn)行介紹，安裝在(zai)安裝Kubernetes之前，安裝請確保您的安裝系統滿(mǎn)足以下要求：

硬件要求：至少2個(gè)CPU核心，4GB內存(建議8GB或更多),足夠的磁盤(pán)空間(建議20GB或更多)。

軟件要求：已安裝Docker或rkt等容器運行時(shí)。

網(wǎng)絡(luò )要求：具有IPv4地址的主機。

2、添加Kubernetes官方倉庫

在安裝Kubernetes之前，需要先添加官方(′ω｀*)倉庫，以便下載所需的軟件包，在終端中執行以下命令：

sudo apt-get update &&am??p; sudo apt-??get install -y apt-transport-https curlcurl -s https(╬?益?)://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -echo "deb http://apt.??kubernet?es.io/ kubernetes-xenial mai???n" | sudo tee -a /etc/apt/sources.list.d/kubernetes.listsudo apt-get update

安裝kubeadm和kubelet

1、安裝kubeadm

kubeadm是Kubernetes的控制平面組件，用于初始化主節點(diǎn)?，執行以下命令安裝kubeadm:

sudo apt-get install -y kubelet kubeadm kubectl

2、初始化主節點(diǎn)

在安裝完成后，需要初始化主節點(diǎn)，配置kubelet參數文件：

sudo mkdir -p /etc/systemd/system/ˉ\_(ツ)_/ˉkubelet.service.dsudo nano /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

在打開(kāi)的文件中，添加以下內┐(′д｀)┌容：

[Service]Environment="KUBELET_EXTRA_??ARGS=--pod-network-cidr=192.168.0.0/16"EnvironmentFile=-/etc/default/kubele??tRestart=alwaysExecStart=/usr/( ?ヮ?)bin/kub(?????)el??et --??config=/etc/kubernetes/kubelet.conf --fail-swap-on=false --cgroup-driver=c(′▽?zhuān)?)groupfs --clu( ?° ?? ?°)ster-dns??=<( ?ヮ?)DNS_SERVER??> --cluster-domain=cluster.local --kubeconfig=/var/lib/kubelet/kubeconfig.yaml --pod-infra-container-image=k8s.gcr.io/pause:3.1 --eviction-hard nodefs,nodefs,swap fs.inotifyfs==1 && exec kubelet --config=/etc/kubernetes/kubelet.conf --fail-swap-on=false --cgroup-driver=cgroupfs --cluster-dns=<DNS_SE??RVER> --cluster-domain=cluster(╯°□°）╯︵ ┻━┻.local --kubeconfig=/var/lib/kub???el(′ω｀)et/kubeconfig.yaml --pod-infra-contai(???)ner-image=k8s.gcr.io/pause:3.1 --eviction-hard nodefs,nodefs,swap fs.inotifyfs==1"

注意替換<DNS_S┐(′д｀)┌ERVER>為您的DNS服務(wù)器地址，保??存并退出文件，然后重新加載systemd配置：

sudo systemct(╯°□°）╯︵ ┻━┻l daemon-reload

啟動(dòng)并設置開(kāi)機自啟動(dòng)kubelet服務(wù)：

sud??o systemctl enable kubelet && sudo systemctl start kubelet

安裝網(wǎng)絡(luò )插件

Kubernetes支持多種??網(wǎng)絡(luò )插件，如Flannel、Calico等(╯°□°）╯︵ ┻━┻，本文以Flannel為例進(jìn)行介紹，安裝Flannel相關(guān)依賴(lài)：
