Docker container was ran as user mysql, which leads to permission denied issue.

root@vagrant-ubuntu-trusty-64:/compilebox/API/temp/testfolder# docker run -u mysql -e 'NODE_PATH=/usr/local/lib/node_modules' -i -t -v  "/compilebox/API/temp/testfolder":/usercode virtual_machine /usercode/script.sh python file.py 
/usercode/script.sh: line 41: /usercode/logfile.txt: Permission denied
/usercode/script.sh: line 42: /usercode/errors: Permission denied
Hello!
*-COMPILEBOX::ENDOFOUTPUT-* .03
mv: cannot stat '/usercode/logfile.txt': No such file or directory

If you actually run commands in script.sh one by one in docker container, /usercode belongs to root but not mysql. User mysql does not have permission to create /usercode/logfile.txt and /usercode/errors.

This could be fixed by changing docker user to root.

I am wondering why we need sql in docker container? Is it possible to remove it? I can't see anywhere else has dependency on mysql other than following ones:

$ grep -r mysql .
./DockerSandbox.js:    var st = this.path+'DockerTimeout.sh ' + this.timeout_value + 's -u mysql -e \'NODE_PATH=/usr/local/lib/node_modules\' -i -t -v  "' + this.path + this.folder + '":/usercode ' + this.vm_name + ' /usercode/script.sh ' + this.compiler_name + ' ' + this.file_name + ' ' + this.output_command+ ' ' + this.extra_arguments;
./Payload/sql_runner.sh:sudo service mysql start
./Payload/sql_runner.sh:mysql  mysql< create_user.sql -u'root' 
./Payload/sql_runner.sh:mysql  ri_db < $1 -u'test' -p'test123'
./Payload/sql_runner.sh:mysql  mysql< destroy_user.sql -u'root'
./temp/testfolder/sql_runner.sh:sudo service mysql start
./temp/testfolder/sql_runner.sh:mysql  mysql< create_user.sql -u'root' 
./temp/testfolder/sql_runner.sh:mysql  ri_db < $1 -u'test' -p'test123'
./temp/testfolder/sql_runner.sh:mysql  mysql< destroy_user.sql -u'root'

compile.remoteinterview.io does not show anything.

i want to add a functionality to compile the code against multiple test cases. any ideas how can i do so.
example:
i have a python code
def simpleArraySum(n,ar):
s = 0
for i in ar:
s += i
return s
n = int(raw_input().strip())
ar = map(int, raw_input().strip().split(' '))
result = simpleArraySum(n,ar)
print(result)

i want to test it against more then one inputs i.e. 6\n1 2 3 4 5 6 and 5\n5 6 9 8 7

I am running on Windows 10 64 bit, what is the problem here. It seems file.py was not created under temp. I ran UpdateDocker.sh under Setup. What am I missing Thanks

I am able to get execution time for the program. How can I get memory or CPU usage of the program?

Today I got this CERT_UNTRUSTED issue while install the compilebox. I set npm config set strict-ssl false to bypass https. Everything worked fine for now.

Hi,
when i select the language id and run program then its coming time out error. I give what the ever language id same time out issue. may i know whats wrong.

See: http://stackoverflow.com/questions/28933925/docker-timeout-for-container

Basically, writing an infinite loop:

while True:
   print "infinite loop"

Will cause the entire script to freeze up after a certain amount of runs. Anyone have any idea how to fix this? The timeout within DockerTimeout.sh doesn't seem to do anything.

when I access compile.remoteinterview.io
It shows "allgood-west-01 " and a guitarist's picture.

Referencing issue #7 , it doesn't seem to have been addressed, and infinite loops are very much a problem, they don't seem to timeout

Has anybody tried to integrate compilebox with docker-compose? I have tried and haven't succeeded.

From the beginning, I was trying to create docker-in-docker. I had a container with node js app, inside which I had tried to create another container where the code would be executed (virtual_machine). But I didn't know how to do that correctly.

Then I found another way: expose the Docker socket to the container with node js app using this command (described here https://stackoverflow.com/questions/27879713/is-it-ok-to-run-docker-from-inside-docker):

docker run -v /var/run/docker.sock:/var/run/docker.sock ...

Thereby I have access to all my images inside the container with nodejs app.

But when nodejs app creates virtual_machine container, there is always a timeout error:

I think this error raises because nodejs app creates "sibling" container instead of "child" container. I'm not sure. Has anybody struggled with this problem?

Hello,

I don't see anyone mentioning the input stream for the program via Terminal simulator web.

If I have the following block code, how will the input stream enter?

#include <stdio.h>
int main() {
 int a;
 int b;

 scanf("%d", &a);
 printf("You entered for a: %d", a);
 scanf("%d", &b);
 printf("You entered for b: %d", b);
 return 0;
}

You link to https://compile.remoteinterview.io which returns 404

Rust language support would be great.

i want to know that in dockerSandbox.js run , prepare and execute all methods require a success argument but while calling run method we pass nothing, how did it get success then also in execute and prepare er call success()....where this came from why it dont throw a error and what its use

Hey,

I've installed everything following the instructions in the readme but all tests of the language timeout. I installed compilebox on a DigitalOcean instance with 2gigs of RAM which should be sufficient.

This is as far as I'm getting.

Is there a way to take input for compiling javascript, if so may I please have an example?

I need to run this under virtualenv

hello..
i have try to used your docker images but lots of error not success to working.
So please verify it and also possible so make it working script for Ubuntu16 or centos without docker

Thanks

Seems like currently it doesn't output any log on 1. docker launch fail 2. execution fail inside docker.

My test server os is Ubuntu 14.04LTS. And while doing tutorial on README, I got little problem.
I just want to test my installation, and did below command in directory 'API'

 $ npm install .

And, error was occurred.

I suppose there is some problem about version of express,
so I edit package.json as below(just change version specification of express)

 {
  "name": "API",
  "version": "1.0.0",
  "main": "app.js",
  "dependencies": {
    "express": "4.*",
    "express-brute":"*",
    "exports": "*"
  },
  "author": "Osman Ali",

}

Finally installation check is completed.
Is this temporary remedy right way to do?

What is a recommended Amazon EC2 instance for running Compilebox for a low-to-medium traffic website? m3.medium works well, but what about t2.small (with burstable CPU)? Alternatively has anyone tried Google Compute Engine?

Hello
How I can make it run not on localhost (127.0.0.1) ?

Thank you

After running for a while, the Docker instance for running code goes down.
When this happens, the node.js app reports "Execution timed out" (as if the code just wouldn't complete in time) instead of throwing an error that the server is down.

Can I install on Mac OSX?
Because if I want to use Ubuntu/CentOS, I have to install Docker-in-Docker:
Docker image 1: Cent OS/Ubuntu
Docker image 2 (in 1): 'virtual machine'
Then I met many problems with this @@
Thanks you so much!

I install compilebox by this way:

• Create CentOS/Ubuntu image: only contains centos/ubunto + folder code
• Run into container and install in it. But when docker build 'virtual machine', I met many problems. I've solved a few. But now I'm stuck @@:

Any way you think we could allow for running code that asks for standard input? I would be happy to help code if we can come up with a secure way to do it. Thank you for CompileBox!

Ruby Example:

print "Type in your name: "
name = gets()
puts name

I put the custom package like TestPackage. in API/Payload
and I change the DockerSandbox.js to add cp -r for copy the API/Payload/TestPackage(custom package) and It really copy the folder to temp folder

it shows "error: package TestPackage does not exist"
how could i import my custom package in my code?

Hello,

When I compiling a block code C/C++ within some errors:

  #include "iostream"
  using namespace std;

  int mainccc()
  {
    int n, sum = 0;
    //...
    return 0;
  }

(The error at "int mainccc()")

We will get a message "Compilation Failed".

It is not enough.

How do I get fully message error when compiling?

Thanks.

It is said that there are still some security risks running untrusted code in docker, what did you do to do to make docker more safer?

Hi, please refer to this code in the setup Dockerfile:
RUN echo "mysql ALL = NOPASSWD: /usr/sbin/service mysql start" | cat >> /etc/sudoers

What's the reason to setting no permissions to a mysql connection? Do we even need a db connection for code compiling service?

One can include 2 classes in one submission file locally or on Ideone. When including 2 classes in one Java file on Compilebox, it reports "Execution timed out". For example:

class Main{
    public static void main(String[] args) {
        System.out.println("hello world");
    }
}

class Blob{
    int num;
}

This causes a "timeout error":

We have app and which will spin the short term (short span) docker containers. Right now, it runs in Ubunut16.04 server (VM) and we installed docker, and nodejs in same server. We have nodejs app which runs in same server so whenever a request comes in, then the nodejs app will spin up a docker container and execute a user input inside the docker container. Once after the docker finish its job or if it runs out of admin defined resources then the docker container will be forcefully killed (docker kill) and removed (docker rm).

Now my question is, is it best practices to run the Ubunte16.04 docker container and run nodjes app and the short term docker containers inside the Ubunuter16.04 docker container.

In short run a docker inside other docker container.
