Exception in list images - Docker test client with 1.8.0-SNAPSHOT
Hi Devs,
I'm experimenting with jclouds Docker, and trying to invoke some Docker API
calls.
The code snippet of the sample client I'm using is as follows...[1] I'm
trying to list the images.
[1]
Properties overrides = new Properties();
overrides.setProperty(Constants.PROPERTY_MAX_RETRIES, "15");
overrides.setProperty("jclouds.ssh.retry-auth", "true");
overrides.setProperty("jclouds.endpoint", "http://127.0.0.1:4243");
overrides.setProperty("type","docker");
Iterable<Module> modules =
ImmutableSet.<Module> of(new SshjSshClientModule(), new
SLF4JLoggingModule());
ComputeServiceContext computeServiceContext =
ContextBuilder.newBuilder("docker")
.credentials("root","root").modules(modules)
.overrides(overrides).buildView(ComputeServiceContext.class);
ComputeService
computeService=computeServiceContext.getComputeService();
computeService.listImages();
But when this is executed I'm getting following exception [2] , a NPE when
doing a pre-conditions check. I did a debug through the code and found the
values being passed to org.jclouds.docker.domain.Image constructor
are getting null. (for eg, id, parent, created, container etc..).
However, If I do a curl -X GET http://127.0.0.1:4243/images/json, directly
through Docker, I'm getting all the images as the response. [3]
Any idea what could have done wrong in the java client?

Hi Andrea,
Yes, that was the issue. I upgraded to docker 1.1.2 and now it works fine
:) Thanks for the help

Re: Exception in list images - Docker test client with 1.8.0-SNAPSHOT
Posted by Andrea Turli <an...@gmail.com>.
Hi Sajith,
As far as I remember the json responses of version 0.9.x was a bit
inconsistent across differeny API calls, so jclouds-docker had an ad-hoc
gson parser for them. As Docker 1.0.x is now out (and they fix those
inconsistences) we decided to support only stable releasea. So I suggest to
upgrade docker engine at 1.0 or above and give it another try.
HTH,
Andrea

Hi Ignasi,
Thanks for the tip, also please see [1] , I have highlighted the json which
I think gives the parsing exception. According to that I can't see why its
throwing that exception.
Do you have any idea?
@Andrea, docker version is 0.9.1, this is what I got for command docker
--version
Docker version 0.9.1, build 3600720
But, I'm bit confused about the above mentioned json, it
shows "docker_version":"0.10.0"

Re: Exception in list images - Docker test client with 1.8.0-SNAPSHOT
Posted by Sajith Kariyawasam <sa...@gmail.com>.
Hi Ignasi,
Thanks for the tip, also please see [1] , I have highlighted the json which
I think gives the parsing exception. According to that I can't see why its
throwing that exception.
Do you have any idea?
@Andrea, docker version is 0.9.1, this is what I got for command docker
--version
Docker version 0.9.1, build 3600720
But, I'm bit confused about the above mentioned json, it
shows "docker_version":"0.10.0"

Re: Exception in list images - Docker test client with 1.8.0-SNAPSHOT
Posted by Andrea Turli <an...@gmail.com>.
Hi Sajith,
could you also share the docker engine version you are using to have a
better understanding of your environment?
Thanks,
Andrea

Re: Exception in list images - Docker test client with 1.8.0-SNAPSHOT
Posted by Ignasi Barrera <na...@apache.org>.
Hi Sajith,
In the json you've passed all images have the "Id" field, so that NPE
should not appear.
In order to see the real responses you're getting when using the
jclouds compute service, could you configure the logs and enable the
"jclouds.wire" logger [1] at debug level? That will log all the
requests/responses that are being generated and we'll be able to see
how the image list is sent back from the Docker host.
I.
