Configure JFrog Artifactory behind Nginx and Let’s Encrypt SSL

Posted on 116 views

Question: How can I put JFrog Artifactory behind Nginx reverse proxy and Let’s Encrypt SSL certificate?. JFrog Artifactory is a powerful and advanced repository manager designed to integrate with the majority of CI/CD tools to ensure quicker delivery of software from Development to Production.

By default, JFrog Artifactory binds to an IP address and port number on a server which means access is only via IP or Domain name and specified port number. If you’re keen on security, you’ll want to use a reverse proxy such as Nginx to secure access to JFrog Artifactory server.

In this guide, we will discuss how you can configure Nginx to sit in front of JFrog Artifactory server. We assume you already have a running Artifactory server before you follow this guide. If by any chance you don’t have one, our guides below will be helpful.

Once you have JFrog Artifactory server setup, proceed to configure Nginx with Let’s Encrypt SSL as reverse proxy to it.

Step 1: Install Nginx proxy / we server

Install Nginx on the server you want to use for reverse proxy functionalities. This can be the same server running Artifactory or a different server.

# Install Nginx on CentOS / RHEL
sudo yum -y install nginx

# Install Nginx on Fedora
sudo dnf -y install nginx

# Install Nginx on Ubuntu/Debian
sudo apt -y install nginx

Once Nginx web server is installed, start the service and set it to start at system boot.

sudo systemctl start nginx
sudo systemctl enable nginx

Step 2: Install Cerbot tool Tool

Next is the installation of Certbot tool that is used to obtain Let’s Encrypt SSL certificate. Download and install certbot command line tool.

# Ubuntu / Debian
sudo apt-get update
sudo apt-get install certbot

# Fedora
sudo dnf install certbot

# CentOS / Rocky Linux
sudo dnf -y install epel-release
sudo yum -y install certbot

Check if working:

$ certbot --version
certbot 0.40.0

Step 3: Request for Let’s Encrypt SSL Certiticate

You need a working DNS for the domain or subdomain used by the JFrog Artifactory server, e.g artifactory.example.com.

You also need to open port 80 to be able to get the certificate, but only if you have an active firewall.

# CentOS / Fedora / RHEL
sudo firewall-cmd --add-service=http,https --permanent
sudo firewall-cmd --reload

# Ubuntu / Debian
sudo ufw allow proto tcp from any to any port 80,443
sudo ufw status

Once that is done, get Let’s Encrypt Certificate:

export DOMAIN="artifactory.example.com"
export ALERTS_EMAIL="[email protected]"

# Stop nginx service
sudo systemctl stop nginx

# Request for Let's Encrypt SSL
sudo certbot certonly --standalone -d $DOMAIN --preferred-challenges http --agree-tos -n -m $ALERTS_EMAIL --keep-until-expiring

Sample output:

 IMPORTANT NOTES:
 Congratulations! Your certificate and chain have been saved at:
 /etc/letsencrypt/live/artifactory.computingpost.com/fullchain.pem
 Your key file has been saved at:
 /etc/letsencrypt/live/artifactory.computingpost.com/privkey.pem
 Your cert will expire on 2019-07-11. To obtain a new or tweaked
 version of this certificate in the future, simply run certbot-auto
 again. To non-interactively renew all of your certificates, run
 "certbot-auto renew"
 Your account credentials have been saved in your Certbot
 configuration directory at /etc/letsencrypt. You should make a
 secure backup of this folder now. This configuration directory will
 also contain certificates and private keys obtained by Certbot so
 making regular backups of this folder is ideal.

Step 4: Configure Nginx

Create an Nginx configuration file for Jenkins.

sudo vim /etc/nginx/conf.d/artifactory.conf

Paste below to the file.

server 
  listen 80;
  server_name artifactory.example.com;
  return 301 https://$host$request_uri;

 
server 
  listen 443 ssl;
  server_name artifactory.example.com;
  access_log /var/log/nginx/artifactory.jfrog.com-access.log;
  error_log /var/log/nginx/artifactory.jfrog.com-error.log;
  ssl_certificate /etc/letsencrypt/live/artifactory.example.com/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/artifactory.example.com/privkey.pem;

  rewrite ^/$ /artifactory/webapp/ redirect;
  rewrite ^/artifactory/?(/webapp)?$ /artifactory/webapp/ redirect;
  chunked_transfer_encoding on;
  client_max_body_size 0;
  
  if ($http_x_forwarded_proto = '') 
      set $http_x_forwarded_proto  $scheme;
  
 
  location / 
    proxy_read_timeout  900;
    proxy_pass_header   Server;
    proxy_cookie_path   ~*^/.* /;
    if ( $request_uri ~ ^/artifactory/(.*)$ ) 
      proxy_pass          http://127.0.0.1:8081/artifactory/$1;
    
    proxy_pass         http://127.0.0.1:8081/artifactory/;
    proxy_set_header    X-Forwarded-Port  $server_port;
    proxy_set_header    X-Forwarded-Proto $http_x_forwarded_proto;
    proxy_set_header    Host              $http_host;
    proxy_set_header    X-Forwarded-For   $proxy_add_x_forwarded_for;
  

Replace artifactory[dot]example.com with your Artifactory server Domain. When done making changes, validate Nginx configuration file.

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

If the configuration looks fine, start nginx and set it to start at boot.

sudo systemctl restart nginx
sudo systemctl enable nginx

Step 6: Access JFrog Artifactory Web Interface

Access JFrog Artifactory web interface on http://artifactory.example.com.

Artifactory-nginx-reverse-proxy-https-1024x462

You should be redirected from http to https.

Artifactory-nginx-reverse-proxy-https-interface-1024x539

You have successfully configured Nginx as Reverse proxy to JFrog Artifactory server with Let’s Encrypt SSL certificate.
