创建NetworkAttachmentDefinition
有两种方式，一是通过json格式创建，二是通过配置文件配置相关参数
A、 json格式，在spec.config中配置相关参数：
#Execute following command at Kubernetes master
$ cat <<EOF | kubectl create -f -
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
name: macvlan-conf-1
spec:
config: '{
"cniVersion": "0.3.0",
"type": "macvlan",
"master": "eth1",
"mode": "bridge",
"ipam": {
"type": "host-local",
"ranges": [
[ {
"subnet": "10.10.0.0/16",
"rangeStart": "10.10.1.20",
"rangeEnd": "10.10.3.50",
"gateway": "10.10.0.254"
} ]
]
}
}'
EOF
B 在配置文件中配置参数
创建一个NetworkAttachmentDefinition，没有spec，然后在/etc/cni/multus/net.d中写入相关配置，文件中的name与NetworkAttachmentDefinition的name一样
# Execute following command at Kubernetes master
$ cat <<EOF | kubectl create -f -
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
name: macvlan-conf-2
EOF
# Execute following commands at all Kubernetes nodes (i.e. master and minions)
$ cat <<EOF > /etc/cni/multus/net.d/macvlan2.conf
{
"cniVersion": "0.3.0",
"type": "macvlan",
"name": "macvlan-conf-2",
"master": "eth1",
"mode": "bridge",
"ipam": {
"type": "host-local",
"ranges": [
[ {
"subnet": "11.10.0.0/16",
"rangeStart": "11.10.1.20",
"rangeEnd": "11.10.3.50"
} ]
]
}
}
