Daniel Widdis commented on JCLOUDS-657:
---------------------------------------
I just experienced the same/similar issue in jclouds 1.7.3, except on Rackspace
(rather than GCE) and with deletion rather than creation.
I was attempting to delete a node with uppercase characters in the name. I
used the following code to attempt to delete by private IP address (in my case
String ipAddr = "10.208.232.65"):
{code}
nodes = computeService
.destroyNodesMatching(new Predicate<NodeMetadata>() {
@Override
public boolean apply(final NodeMetadata input) {
return input.getPrivateAddresses().contains(ipAddr);
}
});
{code}
The sole instance on my account at the time was named "Cloud-Server-35". I
received:
java.lang.IllegalArgumentException: Object 'Cloud-Server' doesn't match dns
naming constraints. Reason: Should be only lowercase.

> Key: JCLOUDS-657
> URL: https://issues.apache.org/jira/browse/JCLOUDS-657
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-labs-google
> Affects Versions: 1.7.3
> Reporter: Sunil Shah
> Assignee: Chris Custine
>
> JClouds provisioning fails when we try to create nodes in a GCE project that
> has one or more existing instances with names of the format "ss-production" -
> where ss is any two letter string and production is any string.
> These are valid instance names in GCE but fail JClouds validation - which
> seems to split on the hyphen and requires individual components to be greater
> than 3 characters.
> A full stack trace is here:
> https://gist.github.com/ssk2/853ba032135c60621a9a
> I think the offending logic is in this method:
> https://github.com/jclouds/jclouds-labs-google/blob/master/google-compute-engine/src/main/java/org/jclouds/googlecomputeengine/compute/functions/InstanceInZoneToNodeMetadata.java#L82
> - which iterates over all groups.
> To fix, I think it'd be necessary to change how validation happens to
> validate on the entire name.
