--------------------------------------
Summary: Support to assign fixed private IPs and Port number in
addition to network UUIDs for cartridges
Key: STRATOS-507
URL: https://issues.apache.org/jira/browse/STRATOS-507
Project: Stratos
Issue Type: Improvement
Components: Cloud Controller
Affects Versions: 4.0.0 Alpha
Environment: Stratos 4.0.0 Alpha, jClouds 1.7.1
Reporter: Jeffrey Nguyen
Hi Stratos Devs,
I'm currently working on Stratos enhancement to leverage new network API
supported by jClouds [1].
In the current environment, when we attached a list of network UUIDs to a
cartridge and subscribe to this cartridge, the new instance will have private
IPs randomly assigned to each network. We need the ability to specify fixed
private IP for each network.
In addition to fixed private IPs, we could also assign port UUIDs or whatever
the underlined Iaas supports for the networks configuration.
I am currently working on jClouds enhancement [1]. This JIRA is for the
changes required on Stratos side.
Please see [3] below on how the private IPs are specified in the JSON payload.
In the existing implementation of multiple networks [2], the JSON cartridge
definition can specify multiple networks like one below.
{
"name": "networkInterfaces",
"value":
"fb9c21f4-0672-48b2-8279-77334bb63a53,aa1809a2-c32d-4eb8-a5c5-e46f692416e0,1e43f86f-4165-4f2e-8017-dd4cfb5548b0"
}
With this new enhancement, the JSON cartridge definition can specify multiple
networks and fixed private IPs like one below.
{
"name": "networkInterfaces",
"value":
"[{\"uuid\":\"fb9c21f4-0672-48b2-8279-77334bb63a53\",\"fixed_ip\":\"172.16.0.10\"},{\"uuid\":\"aa1809a2-c32d-4eb8-a5c5-e46f692416e0\",\"fixed_ip\":\"172.16.1.11\"}]"
}
Questions:
- Should introduce new property for the new format or should I just use
existing "networkInterfaces" properties, which implies fixing [2]? When
invoking jClouds API, we should set the value one way or the other, but not
both.
- In the current implementation of Stratos, all cartridge properties are
treated as String. Therefore, with this new enhancement, the networks tuples
need to escape the double quotes. Is this okay?
Please let me know what you think.
Regards,
-Jeffrey
