Can't build from source nor run from DockerHub

[marcellodesales]

I'm trying to run from DockerHub and I cannot generate anything... I have Docker 1.2 installed on my server...

What version is this talking about?

Running is not working... Can you guys be more clear about the requirements? Is that the latest Docker?

@marcellodesales Thanks for your question. My only thought is that this is an issue with the version of Docker that you are using. I'm using 1.5.0 here:

$ docker --version
Docker version 1.5.0, build a8a31ef-dirty

Under 1.5, I was able to run the image without problem. Didn't receive any issues when building either:

I'll try and spin-up a Docker 1.2 environment and see if I can re-pro your issue.

Hi @bdehamer

I upgraded my server to 1.6.2 and it's working...

However, there is no image being served... The screen still shows the empty information... I have confirmed that I have docker running...

# root at pppdc9prd5pq in /export/home/mdesales [15:41:02]
$ ls -la /var/run/docker.sock

$ docker run -d -v /var/run/docker.sock:/var/run/docker.sock \

Can you let me know if that's properly set?

[bdehamer]

Hmm. Now I'm wondering if there isn't a browser problem. My log output here looks like this:

Note the call to /images.json. If things are working properly, there should actually be a lot of calls to /images.jsonas the client-side javascript polls the back-end looking for changes.

Are you seeing any errors in the browser? Maybe in the developer tools console?

[bdehamer]

I should probably point-out that we have a hosted version of this same tool now that is much easier to use:

https://imagelayers.io/

The primary difference is that the imagelayers.io tool allows you to inspect images on the Docker Hub instead of images in your local image cache.

[marcellodesales]

I'm aware of imagelayers.io, and I forked in the hopes to generate a hosted version of it... Couldn't get Ruby compiled with Node.js in Alpine yet... So, now I just want a quick way to visualize the images in a given host as we have an Internal registry...

The current problem is on the server I guess :(

[bdehamer]

@marcellodesales it does look like it might be something on the server side. Can you paste the output of running docker images on your system. There may be one image in particular that is tripping it up and I'd love to be able to replicate the issue on my system. Thanks.

[marcellodesales]

@bdehamer here it is!

[bdehamer]

@marcellodesales can I see your docker images output instead of docker ps. The image-graph tool doesn't really care what's running, it only looks at the images in your local Docker image cache. Thanks.

[marcellodesales]

@bdehamer I'm really sorry :) I might have been sleepy :P Here they are...

@marcellodesales I'm still in the process of troubleshooting this (thanks for your patience). If possible, could you paste me the result of hitting the /images.json endpoint in your browser (once you've started the image-graph container). This is the raw JSON output that is consumed by the client-side JavaScript which is responsible for rendering the image graph. I suspect that there is some unexpected value in this output that is causing the problem.

It should look something like this:

[  
   [  
      {  
         "v":"31f630c65071968699d327be41add2e301d06568a4914e1aa67c98e1db34a9d8",

      },
      "",

      "CMD [\"-h\"]"
   ],
. . .

Thanks.

[marcellodesales]

@bdehamer So, the output is extremely long... It also took A LONG TIME to return... Here's the output of the second call...

Marcello-New2015:~ mdesales$ time curl http://pppdc9prd5pq:3000/images.json
real    1m46.749s
user    0m0.006s
sys 0m0.012s

I hope you can find clues from the output below... Or maybe because it is too long?

JSON

@marcellodesales The JSON you sent was super helpful. There are definitely a few entries in there that are causing the rendering problem:

Something about the data in the fabiana/app and marcello/app images is resulting in some odd data in the JSON output.

After removing those images, I was able to get the rest of the data to render without problem:

I'll see if I can't figure out what it is about those images that is causing a problem and try to make a fix.

@marcellodesales

I just pushed a new centurylink/image-graph image with a small fix to the server-side code that I think may address the issue you are seeing. Please pull it down and let me know if it resolves your issue.

[marcellodesales]

@bdehamer Perfect! I will double-check that... Ahh, those images were created for a tech session I gave last year... super old :) Not sure what's going on there, but I will remove them... I will check the fix first, and then remove the image and report back to you!

thanks a lot for the help!

[bdehamer]

It looks like those images were maybe built without using a Dockerfile (i.e. doing a docker run and then a docker commit). When you build images in that way the metadata for the layer is stored a little differently and that is what was causing problems for my script.

I am using Docker on Fedora:

$ cat /etc/redhat-release 
Fedora release 24 (Twenty Four)
$ docker --version
Docker version 1.10.3, build 29066b4/1.10.3

I am seeing the same error mentioned in this issue:

What could be the issue?

[minhoryang]

Related with upserve/docker-api#415.
But they asked to upgrade our excon version to 0.46.0+, not upgrading their requirements spec.
