curl examples for link command

[vnugent]

I'm looking for container linking examples using curl

curl -X POST http://10.16.23.108:43273/containers/links -d { not sure what to do }

[wallrj]

Here's where @smarterclayton explains the format:

• http://lists.openshift.redhat.com/openshift-archives/users/2014-June/msg00051.html

Here's where @smarterclayton explains that links can't currently be modified via the REST API

• http://lists.openshift.redhat.com/openshift-archives/users/2014-June/msg00058.html

Here's a corresponding feature request #223

And here's an example showing how to add links at unit creation time which I posted to the mailing list:

• http://lists.openshift.redhat.com/openshift-archives/users/2014-June/msg00062.html

$ curl -v -X PUT "http://127.0.0.1:43273/container/my-sample-service";
-H "Content-Type: application/json" -d '{"Started": true,
"NetworkLinks": [{"ToPort": 44831, "FromPort": 31337, "FromHost":
"127.0.0.1", "ToHost": "127.0.0.1"}], "Image":
"openshift/busybox-http-app", "Ports": []}'
