Hi, I follow the instruction on “[Using Docker with the CMS open data – Docker pre-exercises](https://cms-opendata-workshop.github.io/workshop2022-lesson-docker/03-docker-for-cms-opendata/index.html)” to install the container using wsl2. And I am stuck at the first step for installing the container for cms\_open\_data\_work. I can’t get expected output for " ``` Setting up CMSSW\_7\_6\_7 CMSSW should now be available. This is a standalone image for CMSSW\_7\_6\_7 slc6\_amd64\_gcc493. (/code/CMSSW\_7\_6\_7/src) ```auto Did I miss some important steps? Other than that, the container for python tool and root is working. ``` ---

The command i use is ```auto docker run -it --name my_od -P -p 5901:5901 -p 6080:6080 -v ${HOME}/cms_open_data_work:/code cmsopendata/cmssw_7_6_7-slc6_amd64_gcc493 /bin/bash ``` it doesn’t have any output. ![image](https://opendata-forum.cern.ch/uploads/default/original/1X/700a7978b5ff36fc54abde97ebb1354aaeea0798.png) ---

Hi! Thanks for your interest in the CMS open data. If you are running the `docker run ...` command in your WSL2 Linux Ubuntu shell, the instructions in the red box under the WSL2 Windows tab on page [Using Docker with the CMS open data – Docker pre-exercises](https://cms-opendata-workshop.github.io/workshop2022-lesson-docker/03-docker-for-cms-opendata/index.html) should help you forward: > If the docker command exits without giving you the output above, see [this post](https://opendata-forum.cern.ch/t/running-cms-opendata-containers-in-wsl2/30) in the CERN Open Data forum (note in particular that the `.wslconfig` file that you need to add must not have a file extension, if Windows adds it automatically, rename the file). Best, Kati for the CMS open data team ---

Hi Kati, after following your instruction to add .wslconfig and shut down wsl with command prompt, nothing changed. The “vsyscall=emulate” didn’t show up. And my original “docker run …” command still returns nothing. And then I follow your to follow your second instruction to check ‘.wslconfig.txt’, but I couldn’t find the ‘.wsl’ directory. Could it be some other name? ---

![issue2](https://opendata-forum.cern.ch/uploads/default/original/1X/43e3c4ab056a0345faf73282bb8434aa5ae2bd25.png) I can’t find the .wsl directory. ---

And I try using both the docker commands for wsl and linux to install the work container. But neither of them returns any output. ---

There’s no `.wsl` directory, just the file `.wslconfig`. You should create it in the `/mnt/c/Users//` directory. If it is not there, the new settings won’t be applied and the `docker run` command with this container won’t start. If `80420` is your Windows user name, you can do the following in the Linux terminal to create the file: ```auto echo [wsl2] > /mnt/c/Users/80420/.wslconfig echo kernelCommandLine = vsyscall=emulate >> /mnt/c/Users/80420/.wslconfig ``` ---

Appreciate your help. The issue is fixed.
