Calico多集群通信

1 添加 ippool#

1.1 配置 ippool#

以clusterA集群为例子,此操作也要在clusterB 执行

1
# 在 clusterA 集群执行
2
# 导出配置文件
3
calicoctl get ippool default-ipv4-ippool -o yaml > clusterA-ippool.yaml
4

5
# 修改配置文件
6
vim clusterA-ippool.yaml

#拷贝到 clusterA 集群执行

calicoctl apply -f clusterA-ippool.yaml

1.2.1 clusterA 集群#

1
calicoctl get ippool -o wide
2

1.2.2 clusterB 集群#

1
get ippool -o wide
2

2 BGP 对等体配置#

以clusterA集群为例子,此操作也要在clusterB 执行,如果需要高可用需要加多个对等体

1
apiVersion: projectcalico.org/v3
2
kind: BGPPeer
3
metadata:
4
  name: clusterb-global-peer1
5
spec:
6
  node: clusterBmaster1
7
  peerIP: 10.0.0.1
8
  asNumber: 63456 # 通过 `calicoctl get BGPConfiguration` 查看

2.1 查看#

10.0.0.1为clusterB 集群的 master 节点

1
calicoctl node status
2
