libprotobuf error when running Docker

[phoebetse]

I get the following error when running nsjail in the provided Dockerfile:

$ docker build -t nsjailcontainer
Successfully built ...
Successfully tagged nsjailcontainer:latest

$ docker run -it nsjailcontainer nsjail
nsjail: error while loading shared libraries: libprotobuf.so.23: cannot open shared object file: No such file or directory

Is this a bug in the dockerfile? Or is there something I'm missing?

Hi! I cannot reproduce the issue.

$ git clone https://github.com/google/nsjail.git
$ cd nsjail
$ docker build -t nsjailcontainer .
[...]
Successfully built 9000351bf6ab
Successfully tagged nsjailcontainer:latest
$ docker run -it nsjailcontainer nsjail
 Usage: nsjail [options] -- path_to_command [args]

weird, i'm no longer seeing the issue anymore. maybe something intermittent? thanks for looking into this!

Usually this means you are missing the shared library on your system. You can install it like so if apt is your package manager:

sudo apt install libprotobuf23
