Details about how to use Kong in Docker can be found on the DockerHub repository hosting the image: kong. We also have a Docker Compose template with built-in orchestration and scalability. With a Database. Here is a quick example showing how to connect a Kong container to a Cassandra or PostgreSQL container. Create a Docker network. Jan 14, 2018 This page shows how to install, setup and use Docker or Docker CE on RHEL 7 or CentOS 7 server and create your first container. How to install and use Docker on RHEL 7 or CentOS 7 (method 1) The procedure to install Docker is as follows. Jul 05, 2018 To stop a running container, use docker stop, followed by the container ID or name. This time, we’ll use the name that Docker assigned the container, which is sharpvolhard: docker stop sharpvolhard; Once you’ve decided you no longer need a container anymore, remove it with the docker rm command, again using either the container ID or the. The list returned depends on which repositories are enabled, and is specific to your version of CentOS (indicated by the.el7 suffix in this example). Install a specific version by its fully qualified package name, which is the package name (docker-ce) plus the version string (2nd column) starting at the first colon (:), up to the first hyphen, separated by a hyphen (-). Jun 09, 2020 Docker is an application that simplifies the process of managing application processes in containers. In this tutorial, you'll install and use Docker Community Edition (CE) on Ubuntu 20.04.

With a Database

Here is a quick example showing how to connect a Kong container to a Cassandra or PostgreSQL container.

MagicPrefs is a application meant to run in the background all the time, it uses less than 1.5% CPU and is optimized for a minimal impact on system performance. Download a locally running HTML+JS version Find & Replace with Superpowers. We’ve all grown up using the Find or Find & Replace features in webpages, word processors, and databases.

1. Create a Docker network

   You will need to create a custom network to allow the containers to discover and communicate with each other. In this example kong-net is the network name, you can use any name.

2. Start your database

   If you wish to use a Cassandra container:

   If you wish to use a PostgreSQL container:

3. Prepare your database

   Run the migrations with an ephemeral Kong container:

   To setup the installation of macos mojave click continue. In the above example, both Cassandra and PostgreSQL are configured, but you should update the KONG_DATABASE environment variable with either cassandra or postgres.

   Note for Kong < 0.15: with Kong versions below 0.15 (up to 0.14), use the up sub-command instead of bootstrap. Also note that with Kong < 0.15, migrations should never be run concurrently; only one Kong node should be performing migrations at a time. This limitation is lifted for Kong 0.15, 1.0, and above.

4. Start Kong

   When the migrations have run and your database is ready, start a Kong container that will connect to your database container, just like the ephemeral migrations container:

5. Use Kong

   Kong is running:

DB-less mode

The steps involved in starting Kong in DB-less mode are the following:

Install Curl Docker Container Box

1. Create a Docker network

   This is the same as in the Pg/Cassandra guide. We’re also using kong-net as the network name and it can also be changed to something else.

   This step is not strictly needed for running Kong in DB-less mode, but it is a good precaution in case you want to add other things in the future (like a rate-limiting plugin backed up by a Redis cluster).

2. Create a Docker volume

   For the purposes of this guide, a Docker Volume is a folder inside the host machine which can be mapped into a folder in the container. Volumes have a name. In this case we’re going to name ours kong-vol

   You should be able to inspect the volume now:

   The result should be similar to this:

   Notice the MountPoint entry. We will need that path in the next step.

3. Prepare your declarative configuration file

   The syntax and properties are described on the Declarative Configuration Format guide.

   Add whatever core entities (Services, Routes, Plugins, Consumers, etc) you need there.

   On this guide we’ll assume you named it kong.yml.

   Save it inside the MountPoint path mentioned in the previous step. In the case of this guide, that would be /var/lib/docker/volumes/kong-vol/_data/kong.yml

4. Start Kong in DB-less mode

   Although it’s possible to start the Kong container with just KONG_DATABASE=off, it is usuallydesirable to also include the declarative configuration file as a parameter via theKONG_DECLARATIVE_CONFIG variable name. In order to do this, we need to make the file“visible” from within the container. We achieve this with the -v flag, which mapsthe kong-vol volume to the /usr/local/kong/declarative folder in the container.

5. Use Kong

   Kong should be running and it should contain some of the entities added in kong.yml:

   For example, get a list of services:
