日志一直刷：7709 leaderelection.go:441] Failed to update lock optimistically: Operation cannot be fulfilled on leases.coordination.k8s.io “k3s”: the object has been modified; please apply your changes to the latest version and try again, falling back to slow path
复现步骤:
- 安装 K3s 的命令:
第一台server
INSTALL_K3S_SKIP_DOWNLOAD=true \
K3S_TOKEN=domino \
INSTALL_K3S_EXEC="server \
--node-name k3s-server01 \
--node-ip=192.168.0.111 \
--system-default-registry 192.168.0.108:80 \
--cluster-init \
--tls-san=192.168.0.111 \
--tls-san=192.168.0.112 \
--tls-san=192.168.0.113 \
--tls-san=192.168.0.200 \
--tls-san=domino.local \
--flannel-iface=ens33" \
./install.sh
第二台server：
INSTALL_K3S_SKIP_DOWNLOAD=true \
K3S_TOKEN=domino \
INSTALL_K3S_EXEC="server \
--node-name k3s-server02 \
--node-ip=192.168.0.112 \
--system-default-registry 192.168.0.108:80 \
--server https://192.168.0.111:6443 \
--tls-san=192.168.0.111 \
--tls-san=192.168.0.112 \
--tls-san=192.168.0.113 \
--tls-san=192.168.0.200 \
--tls-san=domino.local \
--flannel-iface=ens33" \
./install.sh
第三台server：
INSTALL_K3S_SKIP_DOWNLOAD=true \
K3S_TOKEN=domino \
INSTALL_K3S_EXEC="server \
--node-name k3s-server03 \
--node-ip=192.168.0.113 \
--system-default-registry 192.168.0.108:80 \
--server https://192.168.0.111:6443 \
--tls-san=192.168.0.111 \
--tls-san=192.168.0.112 \
--tls-san=192.168.0.113 \
--tls-san=192.168.0.200 \
--tls-san=domino.local \
--flannel-iface=ens33" \
./install.sh
预期结果:
实际结果:
