Kong Gateway required persistent storage to store data such as Routes and Services. It provides two options to install namely: Using a database and Without a database. This tutorial primarily focused on the “Using a database” option. Kong Gateway supports two types of databases Postgres and Cassandra. But Cassandra support is already deprecated and eventually it will be removed from Kong Gateway 4.0 release.
Step 01: Install PostgreSQL according to your operating system.
psql -U postgres -h localhost
Step 02: Create a user “kong” as the owner of database “kong”. Change the password of user kong.
Step 03: Install Kong Gateway on Mac
brew tap kong/kong
brew install kong
Step 04: Download default configuration file (kong.conf.default) from [1] and copy the file to location /etc
sudo mkdir -p /etc/kong
sudo cp kong.conf.default /etc/kong/kong.conf
Step 05: Modify the content of kong.conf as below to connect with Postgres database
Step 06: Bootstrap configuration
kong migration bootstrap -c /etc/kong/kong.conf
Step 07: Start Kong Gateway
kong start -c /etc/kong/kong.conf
