# Kong configuration file
# -----------------------
#
# The commented-out settings shown in this file represent the default values.
#
# This file is read when `kong start` or `kong prepare` are used. Kong
# generates the Nginx configuration with the settings specified in this file.
#
# All environment variables prefixed with `KONG_` and capitalized will override
# the settings specified in this file.
# Example:
# `log_level` setting -> `KONG_LOG_LEVEL` env variable
#
# Boolean values can be specified as `on`/`off` or `true`/`false`.
# Lists must be specified as comma-separated strings.
#
# All comments in this file can be removed safely, including the
# commented-out properties.
# You can verify the integrity of your settings with `kong check <conf>`.
#------------------------------------------------------------------------------
# GENERAL
#------------------------------------------------------------------------------

#proxy_listen = 0.0.0.0:8000, 0.0.0.0:8443 ssl
# Comma-separated list of addresses and ports on
# which the proxy server should listen.
# The proxy server is the public entrypoint of Kong,
# which proxies traffic from your consumers to your
# backend services. This value accepts IPv4, IPv6, and
# hostnames.
# Some suffixes can be specified for each pair:
# - `ssl` will require that all connections made
# through a particular address/port be made with TLS
# enabled.
# - `http2` will allow for clients to open HTTP/2
# connections to Kong's proxy server.
# - Finally, `proxy_protocol` will enable usage of the
# PROXY protocol for a given address/port.
#
# This value can be set to `off`, thus disabling
# the proxy port for this node, enabling a
# 'control-plane' mode (without traffic proxying
# capabilities) which can configure a cluster of
# nodes connected to the same database.
# Note: see http://nginx.org/en/docs/http/ngx_http_core_module.html#listen for

# Requests from trusted IPs make Kong forward
# their X-Forwarded-* headers upstream.
# Non-trusted requests make Kong insert its
# own X-Forwarded-* headers.
#
# This property also sets the
# `set_real_ip_from` directive(s) in the Nginx
# configuration. It accepts the same type of
# values (CIDR blocks) but as a
# comma-separated list.
#
# To trust *all* /!\ IPs, set this value to
# `0.0.0.0/0,::/0`.
#
# If the special value `unix:` is specified,

# examples of accepted values.
#real_ip_header = X-Real-IP # Defines the request header field whose value
# will be used to replace the client address.
# This value sets the ngx_http_realip_module
# directive of the same name in the Nginx
# configuration.
# If set to `proxy_protocol`, then at least

#client_max_body_size = 0 # Defines the maximum request body size allowed
# by requests proxied by Kong, specified in
# the Content-Length request header. If a
# request exceeds this limit, Kong will
# respond with a 413 (Request Entity Too
# Large). Setting this value to 0 disables
# checking the request body size.
# Note: see http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size
# for further description of this parameter. Numeric values may be suffixed
# with 'k' or 'm' to denote limits in terms of kilobytes or megabytes.
#client_body_buffer_size = 8k # Defines the buffer size for reading the
# request body. If the client request body is
# larger than this value, the body will be
# buffered to disk. Note that when the body is
# buffered to disk Kong plugins that access or
# manipulate the request body may not work, so
# it is advisable to set this value as high as
# possible (e.g., set it as high as
# `client_max_body_size` to force request
# bodies to be kept in memory). Do note that
# high-concurrency environments will require
# significant memory allocations to process
# many concurrent large request bodies.
# Note: see http://nginx.org/en/docs/http/ngx_http_core_module.html#client_body_buffer_size
# for further description of this parameter. Numeric values may be suffixed
# with 'k' or 'm' to denote limits in terms of kilobytes or megabytes.
#error_default_type = text/plain # Default MIME type to use when the request
# `Accept` header is missing and Nginx
# is returning an error for the request.
# Accepted values are `text/plain`,
# `text/html`, `application/json`, and
# `application/xml`.
#------------------------------------------------------------------------------
# DATASTORE
#------------------------------------------------------------------------------
# Kong will store all of its data (such as APIs, consumers and plugins) in
# either Cassandra or PostgreSQL.
#
# All Kong nodes belonging to the same cluster must connect themselves to the
# same database.
#database = postgres # Determines which of PostgreSQL or Cassandra
# this node will use as its datastore.

#cassandra_port = 9042 # The port on which your nodes are listening
# on. All your nodes and contact points must
# listen on the same port.
#cassandra_keyspace = kong # The keyspace to use in your cluster.
#cassandra_timeout = 5000 # Defines the timeout (in ms), for reading
# and writing.
#cassandra_ssl = off # Toggles client-to-node TLS connections
# between Kong and Cassandra.
#cassandra_ssl_verify = off # Toggles server certificate verification if

#cassandra_schema_consensus_timeout = 10000 # Defines the timeout (in ms) for
# the waiting period to reach a
# schema consensus between your
# Cassandra nodes.
# This value is only used during

#------------------------------------------------------------------------------
# DATASTORE CACHE
#------------------------------------------------------------------------------
# In order to avoid unecessary communication with the datastore, Kong caches
# entities (such as APIs, Consumers, Credentials...) for a configurable period
# of time. It also handles invalidations if such an entity is updated.
#
# This section allows for configuring the behavior of Kong regarding the
# caching of such configuration entities.
#db_update_frequency = 5 # Frequency (in seconds) at which to check for
# updated entities with the datastore.
# When a node creates, updates, or deletes an
# entity via the Admin API, other nodes need
# to wait for the next poll (configured by
# this value) to eventually purge the old
# cached entity and start using the new one.
#db_update_propagation = 0 # Time (in seconds) taken for an entity in the
# datastore to be propagated to replica nodes
# of another datacenter.
# When in a distributed environment such as
# a multi-datacenter Cassandra cluster, this
# value should be the maximum number of
# seconds taken by Cassandra to propagate a
# row to other datacenters.
# When set, this property will increase the
# time taken by Kong to propagate the change
# of an entity.
# Single-datacenter setups or PostgreSQL
# servers should suffer no such delays, and
# this value can be safely set to 0.
#db_cache_ttl = 3600 # Time-to-live (in seconds) of an entity from
# the datastore when cached by this node.
# Database misses (no entity) are also cached
# according to this setting.
# If set to 0, such cached entities/misses
# never expire.
#------------------------------------------------------------------------------
# DNS RESOLVER
#------------------------------------------------------------------------------
# By default the DNS resolver will use the standard configuration files
# `/etc/hosts` and `/etc/resolv.conf`. The settings in the latter file will be
# overridden by the environment variables `LOCALDOMAIN` and `RES_OPTIONS` if
# they have been set.
#dns_resolver = # Comma separated list of nameservers, each
# entry in `ip[:port]` format to be used by
# Kong. If not specified the nameservers in
# the local `resolv.conf` file will be used.
# Port defaults to 53 if omitted. Accepts
# both IPv4 and IPv6 addresses.
#dns_hostsfile = /etc/hosts # The hosts file to use. This file is read
# once and its content is static in memory.
# To read the file again after modifying it,
# Kong must be reloaded.
#dns_order = LAST,SRV,A,CNAME # The order in which to resolve different
# record types. The `LAST` type means the
# type of the last successful lookup (for the
# specified name). The format is a (case
# insensitive) comma separated list.
#dns_stale_ttl = 4 # Defines, in seconds, how long a record will
# remain in cache past its TTL. This value
# will be used while the new DNS record is
# fetched in the background.
# Stale data will be used from expiry of a
# record until either the refresh query
# completes, or the `dns_stale_ttl` number of
# seconds have passed.
#dns_not_found_ttl = 30 # TTL in seconds for empty DNS responses and
# "(3) name error" responses.
#dns_error_ttl = 1 # TTL in seconds for error responses.
#dns_no_sync = off # If enabled, then upon a cache-miss every
# request will trigger its own dns query.
# When disabled multiple requests for the
# same name/type will be synchronised to a
# single query.
