## How to Setup
Need install docker to run the platform
`docker` and `docker-compose` (For Debian):
```
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -
echo 'deb https://download.docker.com/linux/debian stretch stable' > /etc/apt/sources.list.d/docker.list
apt-get update
apt-get install docker-ce
pip install docker-compose
```
After that, download the zip file from the [release](https://github.com/Hong5489/Custom-CTFd-Engine/releases), then extract it.
Change the `hostname` of proxy container in `docker-compose.yml` to match your website, if you run locally then change to `localhost`
After that, run this and wait for it to build!
```
docker-compose up
```
## SSL cert
You can use your own SSL cert, just replace the cert in `CTFd/ssl` folder
If you wanna try without HTTPS, can change the `nginx.conf` to this:
```
user nobody nogroup; pid /tmp/nginx.pid; error_log /var/log/nginx/error.log;
# Best set to 1 as long as CTFd is served up from the same host
worker_processes 1; events {
worker_connections 1024; # increase if you have lots of clients
accept_mutex off; # set to 'on' if nginx worker_processes > 1
use epoll; # a fast event mechanism for Linux 2.6+
}
http {
resolver 127.0.0.11;
include mime.types;
# fallback in case we can't determine a type
default_type application/octet-stream;
access_log /var/log/nginx/access.log combined;
# Disable delayed sending of small packets
tcp_nodelay on;
upstream ctfd_app {
#fail_timeout=0 always retry ctfd even if it failed
server ctfd:8000 fail_timeout=0;
}
server {
# if no Host match, close the connection to prevent host spoofing
listen 8000 default_server;
return 444;
}
server {
listen 8000;
server_name $hostname;
keepalive_timeout 5;
