[saikovvuri]

Hello Liz,
Fantastic session . howeever when i am trying to following the instructions for setting rootfs using chroot, not able to make it work

root@simpleLinuxVM:/# go run main.go run /bin/bash
Running [/bin/bash]
Running [/bin/bash]
panic: fork/exec /bin/bash: no such file or directory

Appreciate your advice.

Hi thanks for your talks !

I've got the same problem, even though, I tried the same code of multiple of your differents talks on "building container from scratch". Finally I tried the code of your repo and I still have this issue :

panic: fork/exec /bin/bash: no such file or directory

My filesystem that I use as a folder is supposed to work, I tried the bash binary which is in it and it works from the host.
(For information I took this from this repo : https://github.com/mugli/container-from-scratch-in-go)

Thank you in advance for the help
