Kubernetes?安裝flannel組件的過程(本地?kube-flannel.yml?文件)
更新時間：2025年03月17日 09:35:21 作者：燃燈工作室
文章介紹了如何在無法直接訪問raw.githubusercontent.com的情況下,通過科學(xué)上網(wǎng)或下載kube-flannel.yml文件源碼來部署Flannel網(wǎng)絡(luò)插件的方法,感興趣的朋友一起看看吧
可以直接用
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
搞定，但是 raw.githubusercontent.com已經(jīng)被墻了，如果可以科學(xué)上網(wǎng)，上面可以直接搞定，如果不能科學(xué)上網(wǎng)，這里放上kube-flannel.yml文件的源碼
生產(chǎn)文件后，在文件所有目錄執(zhí)行
kubectl apply -f kube-flannel.yml
kube-flannel.yml 文件
cat <<EOF > kube-flannel.yml
