docker build fails on Ubuntu 15.04

[davidwincent]

Following the instructions at https://github.com/aspnet/Home/blob/dev/GettingStartedDeb.md does not work.

My working copy of HelloWeb is: https://github.com/aspnet/Home/tree/1d06f1f9352e6ce75f0602f19bbcb04b01dc9ccb/samples/latest/HelloWeb
My docker version is: 1.5.0, build a8a31ef
Dockerfile: https://github.com/aspnet/Home/blob/1d06f1f9352e6ce75f0602f19bbcb04b01dc9ccb/samples/latest/HelloWeb/Dockerfile

sudo docker build -t aspnet-home-helloweb .

Your error does not seem related to the aspnet image but Docker Hub in general. Can you pull the base image again and other various images to see if it works.

[davidwincent]

Hi.
Other images I have tried seems to work fine. For example:

sudo docker pull docker

I also tried removing all images and pulling them again. I get the same "Error pulling image (latest) from microsoft/aspnet, HTTP code 400" when issuing this command:

sudo docker pull microsoft/aspnet

@davidwincent Hmm interesting, I am able to pull using this command just fine on a clean docker engine.

I suggest you to look at your Docker engine logs first about these errors... Those should have more info about the HTTP 400s you are getting (if you're on ubuntu 15+ journalctl -u docker, if lower /var/log/upstart/docker.log)

As a simple mitigation, please try removing all the images and then pull. I have no idea why this is occurring, still does not seem it is about microsoft/aspnet to me. If this doesn't solve your problem we should open an issue at docker/docker repo, simply because this shouldn't be happening to any image under normal circumstances.

Hi @ahmetalpbalkan
I change to docker 1.8 instead of 1.5 and now it works better. Had to run the "sudo docker build -t aspnet-home-helloweb ." a couple of times to get rid of the request timeouts.

Now I am stuck on the following command:

sudo docker run -it -p 5004:5004 aspnet-home-helloweb

=>

System.InvalidOperationException: Unable to load application or execute command 'project.json'. Available commands: web, kestrel.

Will inform the aspnet team. Thanks.

@davidwincent are you using the dockerfile at https://github.com/aspnet/Home/tree/dev/samples/1.0.0-beta7/HelloWeb ? This looks like a usage error.

[davidwincent]

I am using: https://github.com/aspnet/Home/tree/dev/samples/latest/HelloWeb

Is it the same?

[ahmetb]

@davidwincent turns out repo owners forgot to point samples/latest to actual latest release... Please use the link I provided above, in the meanwhile I opened an issue at dotnet/aspnetcore#936 .

[davidwincent]

Thanks! Works like a charm!

If any other lost soul is to find this thread, here is how I installed docker.io
https://docs.docker.com/installation/ubuntulinux/

(do not use apt-get install docker.io - it will give you an outdated version)
