Your CNI network configuration seems a bit odd to me:
{
"cniVersion": "0.3.0",
"name": "ipv4",
"type": "host-local", <--- main plugin
"isGateway": "true",
"ipMasq": "true",
"ipam": {
"type": "host-local", <--- IPAM plugin
"subnet": "10.22.0.0/16",
"routes": [
{ "dst": "0.0.0.0/0" }
]
}
}
So you set the type of both main plugin and IPAM plugin to "host-local".
But I think "host-local" is just an IPAM plugin, for the main plugin, I
think you need to use another one, e.g., "bridge", you can take a look at
the link below for more details about bridge plugin:
