Problem running image, image fails to start, uncertainty over ip to use in URL, internal networking issue?

Docker Desktop for Windows
1

Hi,

I am new to docker. My host OS is W10 Enterprise 64bit, I installed docker v18.06.

I was following the guide here to install docker and run the image. I think the guide for windows is a little out of date, but nevertheless, I thought it should be ok.

https://miykael.github.io/nipype_tutorial/notebooks/introduction_docker.html

I sucessfully installed docker in that I could pull and run hello world. I could pull the image I was interested in (miykael/nipype_tutorial), but on trying to run the image, the URL I am given does not work in my browser (firefox). I have tried replaing the front of the URL with localhost, host machine i/p and the DockerNAT i/p (I thought this would be the right one), but with no luck. Any ideas what is going wrong here?

See my powershell command and o/p:

Copy/paste this URL into your browser when you connect for the first time,

Replying to my post as things have moved on. I updated docker yesterday, I now get a new error. See below.

This looks to be an issue with proxies and networking. Any ideas how to resolve?

docker run -it --rm -p 172.31.252.209:8888:8888 miykael/nipype_tutorial jupyter notebook

C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: driver failed programming external connectivity on endpoint adoring_golick (c4f625853b130d9a6d03bc57ded91cd64036c76d4717ad182119bfa4cb5efda9): Error starting userland proxy: mkdir /port/tcp:172.31.252.209:8888:tcp:172.17.0.2:8888: input/output error.

Solved.

I was digging around on various forums looking into the new error i was receiving. I saw one post suggesting ‘experimental features’ from Docker settings > Daemon, should be turned off. In hope rather than expectation, I turned experimental features ‘on’, as my setting was already off. Miraculously, this allows me to run the image and jupyter notebook. No idea why.

The url i had to copy onto my browser went as follows:

http://(572887568e37 or 127.0.0.1):8888/?token=a069361e348d97b30b42db38dcaa725b0ff1ff3cf9b21a68

where I edited it in the browser and selected the 127.0.0.1 i/p

i.e. ran the following in the browser…

http://127.0.0.1:8888/?token=a069361e348d97b30b42db38dcaa725b0ff1ff3cf9b21a68

Thanks for the help

Webbrowser is part of the python standard library, you don’t have to install a separate package to use it because it comes bundled with your python installation. If you want to get recognized browsers on your system:

import webbrowser
print webbrowser._browsers

If you directly use webbrowser.open() - it will always open the link in the default browser. What you can do is to register the any other browser and then launch a new tab. Something like this:

webbrowser.register(name, constructor, instance=None)

Once a python browser type is registered, the get() function can return a controller for that browser type. You can run open, open_new and open_new_tab on the controller object. This will ensure the commands are executed on the same browser instance you opened.

import webbrowser    
url='https://www.google.com'
chrome_path="C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe"
webbrowser.register('chrome', None,webbrowser.BackgroundBrowser(chrome_path),1)
webbrowser.get('chrome').open_new_tab(url)
