About remote access openstack nova using jclouds

[Yong Tang]

Hi Adrian

Yesterday, I tried Quick Start Sample for openstack[1],
[1]: http://www.jclouds.org/documentation/quickstart/openstack/

And, my client and openstack are not the same machine.

If I put sample into the machine of my openstack, then anything is ok.

However, if I put sample into my client, then, while executing the
sample, firstly, an exception happened as following:

...
Connection refused: connect connecting to GET
http://localhost:8774/v1.1/e3cbe760ea2a413a900a749c9cf42b6b/servers/detail
HTTP/1.1
...

Then, I modified the sample and added the following,

Properties overrides = new Properties();
overrides.setProperty(Constants.PROPERTY_ENDPOINT,
"http://10.167.133.44:8774/v1.1/");

ComputeServiceContext context =
ContextBuilder.newBuilder(provider).overrides(overrides)
	            .endpoint("http://10.167.133.44:5000/v2.0/")
...

While executing the sample again, although the previous exception did
not happen, another exception happened,

...
com.google.common.util.concurrent.UncheckedExecutionException:
org.jclouds.http.HttpResponseException: Server rejected operation
connecting to POST http://10.167.133.44:8774/v1.1/tokens HTTP/1.1

        at com.google.common.cache.LocalCache.get(LocalCache.java:3990)
        at
com.google.common.cache.LocalCache.getOrLoad(LocalCache.java:3994)
        at
com.google.common.cache.LocalCache$LocalLoadingCache.get(LocalCache.java:4878)

        at
org.jclouds.openstack.keystone.v2_0.config.KeystoneAuthenticationModule$2.get(KeystoneAuthenticationModule.java:202)
...

So, I want to ask whether I need to use SSH way not simply using
user/pwd to access openstack or not？ And if yes, could you please give
me some advice how to modify the sample?

Thanks

Hi Yong,

I think all you should need to do is completely remove those overrides. You really only need to change the endpoint of the ContextBuilder in this scenario.

      ComputeServiceContext context = ContextBuilder.newBuilder(provider)

            .endpoint("http://10.167.133.44:5000/v2.0/")

            .credentials(identity, password)

            .modules(modules)

            .buildView(ComputeServiceContext.class);

HTH,

Everett

Hi Everett,

Thanks your reply very much!
I have resolved the issue. You are right  and in my openstack env, there is a problem of endpoint which url uses "localhost:xxxx", so, once from my client to access openstack, the result will be failed.

Thanks again!

Deeply, in this secne(remote client access), if using default_catalog.templates, you must change endpoints's url from localhost into real ip(eg. in my env, it is 10.167.133.44) in /etc/keystone/default_catalog.templates. Otherwize, jclouds sample can not work normally.

Thanks
