How to run Linux GUI apps with Bash on Windows

Update: New distro’s coming to Bash/WSL via Windows Store

April 11th passed and now we have another big update of Windows 10 called the Creators update. It adds a lot of new features but the most interesting one from a developer point of view is the Bash console.

Before the Creators update we had bash but it was at an early stage. People that wanted to play with it early had to register for Insiders update of their OS. Now all of us have the latest features with an official stable update.

The new linux subsystem now comes with Ubuntu 16.04 LTS which gives us a lot of new things and also the updated allows a lot more linux software to run.

My favorite update is the one that allows the file watchers to work. What that means is that nodejs apps like grunt, gulp and friends now just work. Of course there are other updates and fixes that allow a full development environment to be set using only the bash console. You don’t need to install the Windows alternatives of the apps you need. Just use bash and run apt-get install xxxx. Software like git, nodejs/npm, php, ruby can be ran under bash now.

One thing that needs improvement for me now is when I use browser sync, it cannot open the browser and I want it to open the default browser I set under Windows. However you can still open you browser and go to http://localhost:3000 and it works.

We’ll see in the near future how many console apps we can use. I personally want bash to be my default shell in every shell program and IDE I have and to run without problems with paths or environment: just like if using bash.exe for windows. I also need to check how mysql, mongodb, docker and similar software behaves. Still having everything that I use for web development under the bash console is way better than using ported to Windows software or a slow virtual machine.

My advice for you is to start using bash on Windows today, set up your own environment and report any error you have on their Github issues pages.

No Internet access from your Docker container? Check this out!

After a recent update I started having issues with my containers that hosted apps which were accessing the outside world periodically. At first I couldn’t understand where the problem is. I’ve been checking a lot Github issues without success and finally I remembered that I’ve made an update to my host which updated the kernel.

What I needed now is to find a way to boot with an older kernel selected by default. I started looking in Stackoverflow pages and blogs and found a way to set any kernel that I already have installed as the default one.

Here are the steps I took to fix my problem(my host is running Ubuntu linux):

  • check the /boot/grub/grub.cfg file for all available options you have. The name of every kernel installed is there. Pick one that is older than the latest installed. You have to look for entries like: “menuentry ‘Ubuntu, with Linux 3.13.0-113-generic'”. You will use the “Ubuntu, with Linux 3.13.0-113-generic” part
  • next open the /etc/default/grub file and look for the GRUB_DEFAULT entry
  • combine your kernel config name from point one from above with “Advanced options for Ubuntu” or “Previous Linux versions” for older Ubuntu versions (<14.04). You’ll have to have a similar string like this one now: “Previous Linux versions>Ubuntu, with Linux 3.13.0-92-generic”. Set GRUB_DEFAULT to this string like: GRUB_DEFAULT=Previous Linux versions>Ubuntu, with Linux 3.13.0-92-generic
  • you can use numeric values for GRUB_DEFAULT but it’s not recommended as the number will point to a random kernel config after the next update
  • save, run sudo update-grub and restart

Now you should have an Internet access from inside the Docker containers. This is just a temporary solution so don’t leave it like this, especially running with an older kernel. Better check you configuration and even reinstall everything on your host, use a newer linux distro, etc.


Docker 1.9.0 and the new network configuration

Docker 1.9 is here and it introduces a new way to handle the networking between containers.
Because docker containers should live a short live before being replaced with their new versions one should ask himself do we really need the static IP that was existing until now and assigned to the Docker’s bridge? The usual IP you will see was

After upgrading this IP will be gone. Instead other IPs will be created dynamically. Of course there will be another IP like assigned to the docker0 bridge. You can use it if you are brave enough but better not.
However if you need a quick fix before going to bed you can use the Docker’s –bip parameter to set the bridge IP back to

Another way is to go back to version 1.7.1 using your OS’s package manager or direct install/compile.
Later when you decide to start using Docker’s networking the right and better way, you can start from here.

It was not long ago when a similar attack happened against GitHub. I hope in the near future such things become very hard to do for the average hacker and the clever people will prefer to be white hats.
