Hi Jie,
Something like this is injected into the cni json configuration by mesos
"args": {
"org.apache.mesos": {
"network_info": {
"ip_addresses": [
{
"protocol": "IPv4"
}
],
"name": "test-macvtap-cniip"
}
}
},
You can add labels in Marathon with something like this
"ipAddress": {
"networkName": "test-macvtap-cniip",
"labels": {"CNI_ARGS": "192.168.122.172"}
},
Then the injected will look something like
"args": {
"org.apache.mesos": {
"network_info": {
"ip_addresses": [
{
"protocol": "IPv4"
}
],
"labels": {
"labels": [
{
"key": "CNI_ARGS",
"value": "IP=192.168.122.172"
}
]
},
"name": "test-macvtap-cniip"
}
}
},
Yet the cni plugin is afaik not even looking at the
args.'org.apache.mesos'.network_info
configuration, for the cni_args it looks e.g. at args.cni.ips (or an
environment variable)
I have no idea what this org.apache.mesos is even usefull for, unless
you
are customizing plugins. But I guess you rather stick to the cni
standards.
Or is it possible to reference in the cni network json config files
a key of args.'org.apache.mesos'.network_info?

#5592 not working
Marc,
I think the CNI_ARGS that Mesos passed into CNI plugin is the
NetworkInfo object.
https://github.com/apache/mesos/blob/master/include/mesos/mesos.proto#L3096
I don't know if there's a way in Marathon to inject NetworkInfo.labels
from the app definition. Any marathon folks can answer this?

I read the jira issue [0] that labels would be injected into the

json. But I can't get this to work. I have changed the source of a
plugin so it would dump the configuration files and this is how it
looks
like, when you dump the ip configured in the cni network json [1]
as
expected. When adding the labels, you get a totally different json
[2],
so how should this ever work???
This is not working
