If you need to discuss anything Konga related, we have a chatroom on Gitter:

Features

• Manage all Kong Admin API Objects.

Compatibility

From 0.14.0 onwards, Konga is ONLY compatible with Kong 1.x

If you're on an older Kong version , use this branch or konga:legacy from docker hub instead.

Prerequisites

• A running Kong installation
• Nodejs >= 8, <= 12.x (12.16 LTS is recommended)
• Npm

Used libraries

• Sails.js, http://sailsjs.org/
• AngularJS, https://angularjs.org/

Installation

Install npm and node.js. Instructions can be found here.

Install bower, ad gulp packages.

$ git clone https://github.com/pantsel/konga.git
$ cd konga
$ npm i

Configuration

You can configure your application to use your environment specified settings.

There is an example configuration file on the root folder.

.env_example

Just copy this to .env and make necessary changes to it. Note that this .env file is in .gitignore so it won't go to VCS at any point.

Environment variables

These are the general environment variables Konga uses.

Databases Integration

Konga is bundled with It's own persistence mechanism for storing users and configuration.

A local persistent object store is used by default, which works great as a bundled, starter database (with the strict caveat that it is for non-production use only).

The application also supports some of the most popular databases out of the box:

1. MySQL
2. MongoDB
3. PostgresSQL

In order to use them, set the appropriate env vars in your .env file.

Running Konga

Development

$ npm start

Konga GUI will be available at http://localhost:1337

Production

---

In case of MySQL or PostgresSQL adapters, Konga will not perform db migrations when running in production mode.

You can manually perform the migrations by calling $ node ./bin/konga.js prepare , passing the args needed for the database connectivity.

For example:

$ node ./bin/konga.js  prepare --adapter postgres --uri postgresql://localhost:5432/konga

The process will exit after all migrations are completed.

---

Finally:

$ npm run production

Konga GUI will be available at http://localhost:1337

Production Docker Image

The following instructions assume that you have a running Kong instance following the instructions from Kong's docker hub

$ docker pull pantsel/konga
$ docker run -p 1337:1337 \
             --network {{kong-network}} \ // optional
             --name konga \
             -e "NODE_ENV=production" \ // or "development" | defaults to 'development'
             -e "TOKEN_SECRET={{somerandomstring}}" \
             pantsel/konga

To use one of the supported databases

1. Prepare the database

Note: You can skip this step if using the mongo adapter.

You can prepare the database using an ephemeral container that runs the prepare command.

Args

argument	description	default
-c	command	-
-a	adapter (can be postgres or mysql)	-
-u	full database connection url	-

$ docker run --rm pantsel/konga:latest -c prepare -a {{adapter}} -u {{connection-uri}}

2. Start Konga

$ docker run -p 1337:1337 
             --network {{kong-network}} \ // optional
             -e "TOKEN_SECRET={{somerandomstring}}" \
             -e "DB_ADAPTER=the-name-of-the-adapter" \ // 'mongo','postgres','sqlserver'  or 'mysql'
             -e "DB_HOST=your-db-hostname" \
             -e "DB_PORT=your-db-port" \ // Defaults to the default db port
             -e "DB_USER=your-db-user" \ // Omit if not relevant
             -e "DB_PASSWORD=your-db-password" \ // Omit if not relevant
             -e "DB_DATABASE=your-db-name" \ // Defaults to 'konga_database'
             -e "DB_PG_SCHEMA=my-schema"\ // Optionally define a schema when integrating with prostgres
             -e "NODE_ENV=production" \ // or 'development' | defaults to 'development'
             --name konga \
             pantsel/konga
             
             
 // Alternatively you can use the full connection string to connect to a database
 $ docker run -p 1337:1337 
              --network {{kong-network}} \ // optional
              -e "TOKEN_SECRET={{somerandomstring}}" \
              -e "DB_ADAPTER=the-name-of-the-adapter" \ // 'mongo','postgres','sqlserver'  or 'mysql'
              -e "DB_URI=full-connection-uri" \
              -e "NODE_ENV=production" \ // or 'development' | defaults to 'development'
              --name konga \
              pantsel/konga

The GUI will be available at http://{your server's public ip}:1337

It is possible to seed default users on first install.

You may also configure Konga to authenticate via LDAP.

Upgrading

In some cases a newer version of Konga may introduce changes in database schemas. The only thing you need to do is to start Konga in dev mode once so that the migrations will be applied. Then stop the app and run it again in production mode.

if you're using docker, you can lift an ephemeral container, as stated before:

$ docker run --rm pantsel/konga:latest -c prepare -a {{adapter}} -u {{connection-uri}}

FAQ

1. Getting blank page with Uncaught ReferenceError: angular is not defined

In some cases when running npm install, the bower dependencies are not installed properly. You will need to cd into your project's root directory and install them manually by typing

$ npm run bower-deps

2. Can't add/edit some plugin properties.

When a plugin property is an array, the input is handled by a chip component. You will need to press enter after every value you type in so that the component assigns it to an array index. See issue #48 for reference.

3. EACCES permission denied, mkdir '/kongadata/'.

If you see this error while trying to run Konga, it means that konga has no write permissions to it's default data dir /kongadata. You will just have to define the storage path yourself to a directory Konga will have access permissions via the env var STORAGE_PATH.

4. The hook grunt is taking too long to load

The default timeout for the sails hooks to load is 60000. In some cases, depending on the memory the host machine has available, startup tasks like code minification and uglyfication may take longer to complete. You can fix that by setting then env var KONGA_HOOK_TIMEOUT to something greater than 60000, like 120000.
