[Question] The use in containers

[gerardo-junior]

I'm running some tests, to eventually create a packaging continuous integration for my distro and would like to take a concept test in isolated environments . Do any of you have an "official" docker image with the nipe working properly?

ps. if you feel like answering in Portuguese!

[naltun]

@GouveaHeitor would you like nipe containerized? If so, I can get the Dockerfile written.

This could be a cool idea. In theory, the container image can be used to help employ the use of Tor for other containerized applications. Thoughts?

Hi @naltun,

Yes, we would like to see Nipe running in a docker container! I tried to write Dockerfile a few times but I always got some problems/bugs!

If you write Dockerfile, it will be of great help!

Thx!

[naltun]

@GouveaHeitor Alright, I'll try writing a Dockerfile. I'm new to Docker, but I've written a handful of Dockerfiles.

Mind telling me what issues/complications you found when trying?

[htrgouvea]

The problems were related to iptables... I confess that I did not strive to look for the real reasons for this.

[naltun]

@GouveaHeitor that is really helpful info. Thanks!

A couple things I've already found:

1. perl nipe.pl install isn't installing the config files. I'll look into this...
2. iptables isn't installed by default on the perl images I'm using. I've already fixed this by installing it via the Dockerfile.

About point 1, check this out (me inside of the container):

The exit status of perl nipe.pl install is also 0.

About point 2, I believe that all/most perl official container runtimes are using Debian as the system. Currently I am using perl:5.28-stretch, although I tried perl:5.28-slim-stretch (to reduce the image size). I encountered an error here w/ CPAN modules... So for the time being I am going to move forward to the regular stretch image. 👍

Edit for Appending notes:

• I do not think system() subroutine calls are working across the scripts

[naltun]

Currently running into this gem:

iptables v1.6.0: can't initialize iptables table `filter': Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.

Edit: Even running sudo perl nipe.pl start throws this error. Also, I noticed that even though I receive this iptables issue, nipe.pl still exits with a status of 0. This may want to be changed?

[naltun]

I'm working off of this branch, by the way.

So I've gotten everything set up. I can start/stop the service, but perl nipe.pl status, even when the service is started, gives this:
[!] ERROR: sorry, it was not possible to establish a connection to the server.
