Kubernetes - pod未從法蘭絨獲取IP CIDR

Question

我已經在工作節點上成功配置了Flannel。當我在ifconfig上工作時，我看到一個flannel.1接口（我正在使用vxlan）。還有docker0和cbr0接口。

但是，當吊艙出現時，該節點上的泊塢員容器將從法蘭絨接口獲取來自cbr0接口的IP地址和而不是。我嘗試手動刪除cbr0接口，但是當docker容器在pod出現的節點上進行調度時，它會恢復。

碼頭工人開始是這樣的：

dockerd --bip=10.200.50.1/24 --mtu=8951 --iptables=false --ip-masq=false --host=unix:///var/run/docker.sock --log-level=error --storage-driver=overlay

法蘭絨ENV：

$ cat /run/flannel/subnet.env 
FLANNEL_NETWORK=10.200.0.0/16 
FLANNEL_SUBNET=10.200.50.1/24 
FLANNEL_MTU=8951 
FLANNEL_IPMASQ=false 

ifconfig說：

如何確保吊艙的IP地址導出來自法蘭絨界面？

Answer 1

您可能想要檢查您的kubernetes部署，以確保您沒有使用任何網絡插件，因爲您使用的是法蘭絨。
