Understand the default configuration

Kong configuration file

Kong’s configuration properties are set in /opt/bitnami/apps/kong/conf/kong.conf. The most important properties are:

• database: This is the datastore used by Kong, and it is fundamental for setting a Kong cluster. The default image uses Cassandra as its default provider.
• proxy_listen: This is the address at which Kong’s proxy will listen. Even though its default value is 0.0.0.0:8000, open the corresponding port in order to allow remote requests.
• admin_listen: This is the address at which Kong’s administration interface will listen for requests. Its default value is 127.0.0.1:8001 (and 127.0.0.1:8444 for SSL), and you will need to SSH your instance in order to access it.
• cluster: All the properties starting with cluster (such as cluster_encrypt_key or cluster_listen) are important when configuring Kong in cluster mode.

If you modify your configuration file, do not forget to restart Kong:

$ sudo /opt/bitnami/ctlscript.sh restart kong  # Restart Kong

Kong also allows setting configuration via environment variables (which override the contents of kong.conf). You can set them in /opt/bitnami/scripts/setenv.sh.

Find a full reference of the different configuration properties in the configuration reference in Kong’s site.
