Overview

In many cases, an organization may provide access to JFrog Container Registry through a reverse proxy such as NGINX or Apache. In some cases, for example with Docker, this set up is even mandatory. To simplify configuring a reverse proxy, JFrog Container Registry provides a Reverse Proxy Configuration Generator screen in which you can fill in a set of fields to generate the required configuration snippet which you can then download and install directly in the corresponding directory of your reverse proxy server. You can also use the REST API to manage reverse proxy configuration.

For best security, when using JFrog Container Registry behind a reverse proxy, it must be co-located on the same machine as the webserver, and JFrog Container Registry should be explicitly and exclusively bound to localhost.

We also recommend that you set your Custom Based-URL to match your JFrog Container Registry Server Name.

Reverse Proxy Settings

To configure a reverse proxy, in the Admin module, select Configuration | HTTP Settings and execute the following steps in the Reverse Proxy Settings panel:

  • Fill in the fields according to your configuration.
  • Generate the configuration file. You may click the icons in the top right of the screen to view your configuration (which you may copy) or download it as a text file.
  • Place the configuration file in the right place under your reverse proxy server installation and reload the configuration. 

Using NGINX? Note these requirements.

To use NGINX as a reverse proxy to work with Docker, you need NGINX v1.3.9 or higher.

The NGINX configuration file should be placed under the sites-enabled directory.

For more details, please refer to Configuring NGINX.

Using Apache? Note these requirements.

Some features in the Apache configuration are only supported from Apache HTTP Server v2.4.

To use Apache as your reverse proxy server, make sure you have the following modules installed and activated:

  • proxy_http
  • proxy_ajp
  • rewrite
  • deflate
  • headers
  • proxy_balancer
  • proxy_connect
  • proxy_html
  • ssl
  • lbmethod_byrequests
  • slotmem_shm
  • proxy

For more details, please refer to Configuring Apache.

Best practice

When using a reverse proxy, we recommend passing it the X-Artifactory-Override-Base-Url header as follows:

For NGINX:

proxy_set_header X-Artifactory-Override-Base-Url  $http_x_forwarded_proto://$<host>:<server port>/<public context>

For Apache:

RewriteCond %{REQUEST_SCHEME} (.*)
RewriteRule (.*) - [E=my_scheme:%1]
[...]
RequestHeader set X-Artifactory-Override-Base-Url %{my_scheme}e://<server_name>/<app_context>

Web Server Type

The reverse proxy type. Currently NGINX and Apache are supported.

Selecting Embedded Tomcat actually means that you are accessing JFrog Container Registry as a Docker registry using the Repository Path method, so the Tomcat embedded within JFrog Container Registry is routing requests from your Docker client to your JFrog Container Registry Docker registries.

JFrog Container Registry Server Name
The internal server name for JFrog Container Registry. If JFrog Container Registry is installed on the same machine as the Web Server (as urged above for best security) you can use localhost. Otherwise use the IP address or the machine name.
JFrog Container Registry Port
The port configured for JFrog Container Registry. The default value is 8081.
JFrog Container Registry Context Path
The path which will be used to access JFrog Container Registry. If JFrog Container Registry is accessible at the root of the server, leave this field empty.
Public Server Name
The server name which will be publicly used to access JFrog Container Registry within the organization.
Public Context Path
The path which will be publicly used to access JFrog Container Registry. If JFrog Container Registry is accessible on the root of the server leave this field empty.

You can configure access to JFrog Container Registry via HTTP, HTTPS or both (at least one is required). For each of these check boxes that you set, you need to fill in the corresponding fields as follows:

Use HTTP
When set, JFrog Container Registry will be accessible via HTTP at the corresponding port that is set.
HTTP Port
The port for access via HTTP. The default value is 80.
Use HTTPS
When set, JFrog Container Registry will be accessible via HTTPS at the corresponding port that is set.
HTTPS Port
The port for access via HTTPS. The default value is 443.
SSL Key Path
The full path to the key file for access via HTTPS.
SSL Certificate Path
The full path to the certificate file for access via HTTPS.

Docker Reverse Proxy Settings

When using JFrog Container Registry as an on-prem private Docker registry, the Docker client can access JFrog Container Registry through a reverse proxy or directly through JFrog Container Registry's embedded Tomcat.

JFrog Container Registry Cloud Docker Registries

 Note that accessing an JFrog Container Registry Docker registry on a JFrog Container Registry Cloud installation does not use a reverse proxy since it is external to your organization.

Using a Reverse Proxy

The Docker client can access JFrog Container Registry through a reverse proxy using the Subdomain method (recommended) or through the Ports Method.

For each of these methods, your Docker repositories must be configured with the corresponding Reverse Proxy settings in the Docker Repository Configuration Advanced tab. The Reverse Proxy Configuration screen also sets up your Docker Repository configuration.

Configuring JFrog Container Registry as your Docker Registry

This section describes how to obtain your reverse proxy configuration according whether you are using the subdomain method or port bindings. For full details on configuring JFrog Container Registry as a Docker registry using a reverse proxy, please refer to Using a Reverse Proxy.

Using Subdomain

If you select Subdomain as the Reverse Proxy Method, when configuring a Docker Repository, the Registry Name in the Docker Repository Configuration Advanced tab will be set automatically to the required value, and will use the Repository Key as the Subdomain.

Wildcard certificate

Using the Subdomain method requires a Wildcard certificate such as. *.myservername.org. You also need to ensure that the certificate you use supports the number of levels used in your subdomain.

Using Port Bindings

If you select Port as the Reverse Proxy Method, when configuring a Docker Repository, you will need to set the Registry Port in the Docker Repository Configuration Advanced tab. Together with the Public Server Name, this is the port the Docker client will use to pull images from and push images to the repository. Note that in order for all of your Docker repositories to be included in your reverse proxy configuration, you first you need to set the port for each Docker repository defined in your system, and only then generate the reverse proxy configuration. Note also that each repository must be bound to a unique port

Best Practice

We recommend creating a Docker Virtual Repository which aggregates all of your other Docker repositories, and use that to pull and push images. This way you only need to set up the NGINX configuration for that virtual repository.

Using Direct Access

To access your Docker repositories Without a Reverse Proxy you should select Repository Path as the Docker Access Method in the Docker Setting Panel of the HTTP Settings screen.

REST API

JFrog Container Registry also supports managing reverse proxy configuration through the REST API using the following endpoints:

Get Reverse Proxy Configuration
Retrieves the reverse proxy configuration JSON.
Update Reverse Proxy Configuration
Updates the reverse proxy configuration.
Get Reverse Proxy Snippet
Gets the reverse proxy configuration snippet in text format.
