How to Install Judge0 CE on NetBSD

Judge0 CE is an open-source online judge engine that can be installed on a server to host programming contests, automate programming assignments evaluations, and execute user-submitted program snippets. This tutorial will guide you through the process of installing Judge0 CE on a NetBSD system.

Prerequisites

Before you start, make sure your NetBSD system meets the following requirements:

• NetBSD 9.0 or later
• At least 2GB of RAM
• At least 2 CPU cores
• Docker CE installed
• Git installed

Steps

1. Clone the Judge0 CE repository:

git clone https://github.com/judge0/judge0.git

2. Navigate to the cloned directory:

cd judge0

3. Build the Judge0 CE Docker image:

docker build -t judge0-ce .

4. Install necessary libraries for running Docker:

pkg_add procfs fusefs-libs

5. Create a directory to store Judge0 CE data:

mkdir -p /opt/judge0/data

6. Start the Judge0 CE Docker container:

docker run -it --rm \
  -v /opt/judge0/data:/app/data \
  -p 8080:8080 \
  -e JUDGE0_API_BIND_ADDR=0.0.0.0 \
  -e JUDGE0_API_URL=http://localhost:8080/ \
  judge0-ce

7. Judge0 CE should now be accessible at http://localhost:8080.

Conclusion

In this tutorial, we learned how to install Judge0 CE on a NetBSD system. Judge0 CE is a powerful engine that can be used to automate various programming tasks by executing and evaluating user-submitted programs. It can be extended with custom language support and new features, making it a flexible and scalable solution for hosting programming contests and evaluations.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
