Install

With Docker

A Docker image, available for each release, can be pulled

docker pull ghcr.io/thomiceli/opengist:1

It can be used in a docker-compose.yml file :

1. Create a docker-compose.yml file with the following content
2. Run docker compose up -d
3. Opengist is now running on port 6157, you can browse http://localhost:6157

version: "3"

services:
  opengist:
    image: ghcr.io/thomiceli/opengist:1
    container_name: opengist
    restart: unless-stopped
    ports:
      - "6157:6157" # HTTP port
      - "2222:2222" # SSH port, can be removed if you don't use SSH
    volumes:
      - "$HOME/.opengist:/root/.opengist"
    environment:
      CONFIG: |
        log-level: info        

From source

Requirements : Git (2.20+), Go (1.19+), Node.js (16+)

git clone https://github.com/thomiceli/opengist
cd opengist
make
./opengist

Opengist is now running on port 6157, you can browse http://localhost:6157

Configuration

Opengist can be configured using YAML. The full configuration file is config.yml, each default key/value pair can be overridden.

With docker

Add a CONFIG environment variable in the docker-compose.yml file to the opengist service :

environment:
  CONFIG: |
    log-level: info
    ssh.git-enabled: false
    # ...

With binary

Create a config.yml file (you can reuse this one) and run Opengist binary with the --config flag :

./opengist --config /path/to/config.yml

Administration

Use Nginx as a reverse proxy

Configure Nginx to proxy requests to Opengist. Here is an example configuration file :

server {
    listen 80;
    server_name opengist.example.com;

    location / {
        proxy_pass http://127.0.0.1:6157;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Then run :

service nginx restart 

Use Fail2ban

Fail2ban can be used to ban IPs that try to bruteforce the login page. Log level must be set at least to warn.

Add this filter in etc/fail2ban/filter.d/opengist.conf :

[Definition]
failregex =  Invalid .* authentication attempt from <HOST>
ignoreregex =

Add this jail in etc/fail2ban/jail.d/opengist.conf :

[opengist]
enabled = true
filter = opengist
logpath = /home/*/.opengist/log/opengist.log
maxretry = 10
findtime = 3600
bantime = 600
banaction = iptables-allports
port = anyport

Then run

service fail2ban restart 

Configure OAuth

Opengist can be configured to use OAuth to authenticate users, with GitHub or Gitea.

Integrate Github

• Add a new OAuth app in your Github account settings
• Set 'Authorization callback URL' to http://opengist.domain/oauth/github/callback
• Copy the 'Client ID' and 'Client Secret' and add them to the configuration :

  github.client-key: <key>
  github.secret: <secret>
  

Integrate Gitea

• Add a new OAuth app in Application settings from the Gitea instance
• Set 'Redirect URI' to http://opengist.domain/oauth/gitea/callback
• Copy the 'Client ID' and 'Client Secret' and add them to the configuration :

  gitea.client-key: <key>
  gitea.secret: <secret>
  # URL of the Gitea instance. Default: https://gitea.com/
  gitea.url: http://localhost:3000
