How to install Kong Gateway using Docker

To install Kong Gateway, you can follow these steps: 

 Step 1: Choose the installation method: 

  

     Kong Gateway offers different installation methods depending on your operating system and

     requirements. 

    You can choose from Docker, package managers (e.g., Homebrew, Yum, Apt), or manual installation.

     For simplicity, let's go with the Docker installation method.

 Step 2: Install Docker: If you don't have Docker installed, visit the Docker website

              (https://www.docker.com/) and follow the instructions to install Docker for your specific

               operating system. 

 Step 3: Pull the Kong Gateway Docker image: 

 

             Open a terminal or command prompt. Run the following command to pull the Kong Gateway

              Docker image from Docker Hub:

docker pull kong/kong-gateway

Step 4: Run Kong Gateway container: Once the image is pulled, run the following command to start a

             Kong Gateway

docker run -d --name kong-gateway \
  -e "KONG_DATABASE=off" \
  -e "KONG_PROXY_ACCESS_LOG=/dev/stdout" \
  -e "KONG_ADMIN_ACCESS_LOG=/dev/stdout" \
  -e "KONG_PROXY_ERROR_LOG=/dev/stderr" \
  -e "KONG_ADMIN_ERROR_LOG=/dev/stderr" \
  -e "KONG_ADMIN_LISTEN=0.0.0.0:8001" \
  -e "KONG_PROXY_LISTEN=0.0.0.0:8000" \
  -p 8000:8000 \
  -p 8001:8001 \
  kong/kong-gateway

This command starts a Kong Gateway container named "kong-gateway" with the necessary environment variables and port mappings. 

 The -p option maps the container's ports to the host machine, allowing access to Kong Gateway's admin API (port 8001) and proxy API (port 8000). 

 The -e options set various environment variables like the database type (KONG_DATABASE=off disables the database), log configurations, and listen addresses.

 Step 5: Verify Kong Gateway installation: After running the container, wait for a few moments to allow

              Kong Gateway to initialize. 

You can check the logs of the container using the following command:

docker logs kong-gateway

Look for any error messages or indications that Kong Gateway has started successfully. 

 Step 6: Access Kong Gateway admin API: 

 Once Kong Gateway is running, you can access its admin API to configure and manage your Kong Gateway instance. 

Open a web browser and go to http://localhost:8001. You should see the Kong Gateway admin API homepage if everything is working correctly.

 Congratulations! You have successfully installed Kong Gateway using Docker. 

You can now proceed with configuring Kong Gateway and integrating it with your applications as needed
