Errors when standing up default network #79

Closed jebediahelliott closed 4 years ago

jebediahelliott commented 4 years ago

I'm using Ubuntu 20.04 via WSL2 and I'm suspicious that might be what is causing my issue. I'm getting errors when running minifab up. 

jebediah@LAPTOP-JCOAIPDG:~/mywork
$ ./minifab up

If I run minifab up a second time I get different errors

And a third run will produce these errors

If I run minifab cleanup and then minifab up again, this pattern is repeated. I'm not sure if it's relevant, but I noticed that in the execution context my HOST_ADDRESSES does not have a value but in the youtube demo there is a value. Please let me know if there is any other information I can provide. Thanks!

ubuntu 20.04 does not have ifconfig, install ifconfig using this command

sudo apt install net-tools

Then you should be ok.

litong01 commented 4 years ago

@jebediahelliott I think you can either do that or you should simply use the windows version of the minifabric which does not at all require you use ubuntu running on windows. Simply run the same command in a native windows prompt. You should be fine.

jebediahelliott commented 4 years ago

@litong01 Thank you, I was able to get things going using the windows prompt. I did discover that if there are any spaces in the names of the directory structure (C:\Users\Your Name\mywork) that you get errors. I did still have errors on the LInux side though, here is the output:

litong01 commented 4 years ago

@jebediahelliott that is a not supported env. You are running docker inside a windows virtual machine which always causes problem. Minifabric wont support that env. If you do have a real linux env, it will work just fine. Please close this issue. thanks.

jebediahelliott commented 4 years ago

Will do. Thanks for all of your help!
