kong.yml

######
## Kong configuration file. All commented values are default values.
## Uncomment and update a value to configure Kong to your needs.
##
## Lines starting with `##` are comments.
## Lines starting with `#` are properties that can be updated.
## Beware of YAML formatting for nested properties.

######
## Plugins that this node needs to execute.
## By default, Kong will try to execute all installed plugins on every request.
## If you are sure to only use a few plugins, uncomment and update this property to contain
## only those.
## Custom plugins also need to be added to this list.
# plugins_available:
#   - ssl
#   - jwt
#   - ...

######
## The Kong working directory. Equivalent to nginx's prefix path.
## This is where this running nginx instance will keep server files including logs.
## Make sure it has the appropriate permissions.
# nginx_working_dir: /usr/local/kong/

######
## Port which Kong proxies HTTP requests through, consumers will make requests against this port
## so make sure it is publicly available.
# proxy_port: 8000

######
## Same as proxy_port, but for HTTPS requests.
# proxy_ssl_port: 8443

######
## Specify how Kong performs DNS resolution (in the `dns_resolvers_available` property) you want to use.
## Options are: "dnsmasq" (You will need dnsmasq to be installed) or "server".
# dns_resolver: dnsmasq

######
## DNS resolvers configuration. Specify a DNS server or the port on which you want
## dnsmasq to run.
# dns_resolvers_available:
  # server:
    # address: "8.8.8.8:53"
  # dnsmasq:
    # port: 8053

######
## Port on which the admin API will listen to. The admin API is a private API which lets you
## manage your Kong infrastructure. It needs to be secured appropriatly.
# admin_api_port: 8001

######
## Specify which database to use from the databases_available property.
# database: cassandra

######
## Databases configuration.
# databases_available:
  # cassandra:
    ######
    ## Contact points to your Cassandra cluster.
    # contact_points:
    #   - "localhost:9042"

    # timeout: 1000

    # keyspace: kong

    ######
    ## Time (in milliseconds) for which sockets will be keep alive.
    ## for being eventually re-used before being closed.
    # keepalive: 60000

    ######
    ## Keyspace options. Set those before running Kong or any migration.
    ## Those settings will be used to create a keyspace with the desired options
    ## when first running the migrations.
    ## See http://docs.datastax.com/en/cql/3.1/cql/cql_reference/create_keyspace_r.html

    ######
    ## The name of the replica placement strategy class for the new keyspace.
    ## Can be "SimpleStrategy" or "NetworkTopologyStrategy".
    # replication_strategy: SimpleStrategy

    ######
    ## For SimpleStrategy only.
    ## The number of replicas of data on multiple nodes.
    # replication_factor: 1

    ######
    ## For NetworkTopologyStrategy only.
    ## The number of replicas of data on multiple nodes in each data center.
    # data_centers:
    #   dc1: 2
    #   dc2: 3

    ######
    ## If true, will enable client-to-node encryption.
    # ssl: false

    ######
    ## If true, will verify the SSL certificate in use.
    ## `ssl_certificate` must be provided.
    # ssl_verify: false

    ######
    ## **Absolute path** to the certificate authority file for your cluster.
    # ssl_certificate: "/path/to/cluster-ca-certificate.pem"

    ######
    ## If the cluster as authentication enabled, provide a user and a password here.
    # user: cassandra
    # password: cassandra

######
## Time (in seconds) for which entities from the database (APIs, plugins configurations...)
## are cached by Kong. Increase this value if you want to lower the number of requests made
## to your database.
# database_cache_expiration: 5

######
## SSL certificates to use.
# ssl_cert_path: /path/to/certificate.pem
# ssl_key_path: /path/to/certificate.key

######
## Sending anonymous error reports helps Kong developers to understand how it performs.
# send_anonymous_reports: true

######
## Size (in MB) of the Lua cache. This value may not be smaller than 32MB.
# memory_cache_size: 128

######
## The nginx configuration file which allows Kong to run.
## The placeholders will be computed and this property will be written as a file
## by Kong at `<nginx_working_dir>/nginx.conf` during startup.
## This file can tweaked to some extent, but many directives are necessary for Kong to work.
## /!\ BE CAREFUL
