# -----------------------
# 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
#------------------------------------------------------------------------------
#prefix = /usr/local/kong/ # Working directory. Equivalent to Nginx's
# prefix path, containing temporary files
# and logs.
# Each Kong process must have a separate
# working directory.
#log_level = notice # Log level of the Nginx server. Logs are
# found at `<prefix>/logs/error.log`.
# See http://nginx.org/en/docs/ngx_core_module.html#error_log for a list
# of accepted values.
#proxy_access_log = logs/access.log # Path for proxy port request access
# logs. Set this value to `off` to
# disable logging proxy requests.
# If this value is a relative path,
# it will be placed under the
# `prefix` location.
#proxy_error_log = logs/error.log # Path for proxy port request error
# logs. The granularity of these logs
# is adjusted by the `log_level`
# property.
#proxy_stream_access_log = logs/access.log basic # Path for tcp streams proxy port access
# logs. Set this value to `off` to
# disable logging proxy requests.
# If this value is a relative path,
# it will be placed under the
# `prefix` location.
# `basic` is defined as `'$remote_addr [$time_local] '
# '$protocol $status $bytes_sent $bytes_received '
# '$session_time'`
#proxy_stream_error_log = logs/error.log # Path for tcp streams proxy port request error
# logs. The granularity of these logs
# is adjusted by the `log_level`
# property.
#admin_access_log = logs/admin_access.log # Path for Admin API request access
# logs. If Hybrid Mode is enabled
# and the current node is set to be
# the Control Plane, then the
# connection requests from Data Planes
# are also written to this file with
# server name "kong_cluster_listener".
#
# Set this value to `off` to
# disable logging Admin API requests.
# If this value is a relative path,
# it will be placed under the
# `prefix` location.
#admin_error_log = logs/error.log # Path for Admin API request error
# logs. The granularity of these logs
# is adjusted by the `log_level`
# property.
#status_access_log = off # Path for Status API request access
# logs. The default value of `off`
# implies that logging for this API
# is disabled by default.
# If this value is a relative path,
# it will be placed under the
# `prefix` location.
#status_error_log = logs/status_error.log # Path for Status API request error
# logs. The granularity of these logs
# is adjusted by the `log_level`
# property.
#vaults = bundled # Comma-separated list of vaults this node
# should load. By default, all the bundled
# vaults are enabled.
#
# The specified name(s) will be substituted as
# such in the Lua namespace:
# `kong.vaults.{name}.*`.
#opentelemetry_tracing = off # Deprecated: use tracing_instrumentations instead
#tracing_instrumentations = off # Comma-separated list of tracing instrumentations
# this node should load. By default, no instrumentations
# are enabled.
#
# Valid values to this setting are:
#
# - `off`: do not enable instrumentations.
# - `request`: only enable request-level instrumentations.
# - `all`: enable all the following instrumentations.
# - `db_query`: trace database query, including
# Postgres and Cassandra.
# - `dns_query`: trace DNS query.
# - `router`: trace router execution, including
# router rebuilding.
# - `http_client`: trace OpenResty HTTP client requests.
# - `balancer`: trace balancer retries.
# - `plugin_rewrite`: trace plugins iterator
# execution with rewrite phase.
# - `plugin_access`: trace plugins iterator
# execution with access phase.
# - `plugin_header_filter`: trace plugins iterator
# execution with header_filter phase.
#
# **Note:** In the current implementation,
# tracing instrumentations are not enabled in
# stream mode.
#opentelemetry_tracing_sampling_rate = 1.0 # Deprecated: use tracing_sampling_rate instead
#tracing_sampling_rate = 1.0 # Tracing instrumentation sampling rate.
# Tracer samples a fixed percentage of all spans
# following the sampling rate.
#
# Example: `0.25`, this should account for 25% of all traces.
#plugins = bundled # Comma-separated list of plugins this node
# should load. By default, only plugins
# bundled in official distributions are
# loaded via the `bundled` keyword.
#
# Loading a plugin does not enable it by
# default, but only instructs Kong to load its
# source code, and allows to configure the
# plugin via the various related Admin API
# endpoints.
#
# The specified name(s) will be substituted as
# such in the Lua namespace:
# `kong.plugins.{name}.*`.
#
# When the `off` keyword is specified as the
# only value, no plugins will be loaded.
#
# `bundled` and plugin names can be mixed
# together, as the following examples suggest:
#
# - `plugins = bundled,custom-auth,custom-log`
# will include the bundled plugins plus two
# custom ones
# - `plugins = custom-auth,custom-log` will
# *only* include the `custom-auth` and
# `custom-log` plugins.
# - `plugins = off` will not include any
# plugins
#
# **Note:** Kong will not start if some
# plugins were previously configured (i.e.
# have rows in the database) and are not
# specified in this list. Before disabling a
# plugin, ensure all instances of it are
# removed before restarting Kong.
#
# **Note:** Limiting the amount of available
# plugins can improve P99 latency when
# experiencing LRU churning in the database
# cache (i.e. when the configured
# `mem_cache_size`) is full.
#pluginserver_names = # Comma-separated list of names for pluginserver
# processes. The actual names are used for
# log messages and to relate the actual settings.
#pluginserver_XXX_socket = <prefix>/<XXX>.socket # Path to the unix socket
# used by the <XXX> pluginserver.
#pluginserver_XXX_start_cmd = /usr/local/bin/<XXX> # Full command (including
# any needed arguments) to
# start the <XXX> pluginserver
#pluginserver_XXX_query_cmd = /usr/local/bin/query_<XXX> # Full command to "query" the
# <XXX> pluginserver. Should
# produce a JSON with the
# dump info of all plugins it
# manages
#port_maps = # With this configuration parameter, you can
# let the Kong to know about the port from
# which the packets are forwarded to it. This
# is fairly common when running Kong in a
# containerized or virtualized environment.
# For example, `port_maps=80:8000, 443:8443`
# instructs Kong that the port 80 is mapped
# to 8000 (and the port 443 to 8443), where
# 8000 and 8443 are the ports that Kong is
# listening to.
#
# This parameter helps Kong set a proper
# forwarded upstream HTTP request header or to
# get the proper forwarded port with the Kong PDK

#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`.
#upstream_keepalive_pool_size = 60 # Sets the default size of the upstream
# keepalive connection pools.
# Upstream keepalive connection pools
# are segmented by the `dst ip/dst
# port/SNI` attributes of a connection.
# A value of `0` will disable upstream
# keepalive connections by default, forcing
# each upstream request to open a new
# connection.
#upstream_keepalive_max_requests = 100 # Sets the default maximum number of
# requests than can be proxied upstream
# through one keepalive connection.
# After the maximum number of requests
# is reached, the connection will be
# closed.
# A value of `0` will disable this
# behavior, and a keepalive connection
# can be used to proxy an indefinite
# number of requests.
#upstream_keepalive_idle_timeout = 60 # Sets the default timeout (in seconds)
# for which an upstream keepalive
# connection should be kept open. When
# the timeout is reached while the
# connection has not been reused, it
# will be closed.
# A value of `0` will disable this
# behavior, and an idle keepalive
# connection may be kept open
# indefinitely.
#allow_debug_header = off # Enable the `Kong-Debug` header function.
# if it is `on`, kong will add
# `Kong-Route-Id` `Kong-Route-Name` `Kong-Service-Id`
# `Kong-Service-Name` debug headers to response when
# the client request header `Kong-Debug: 1` is present.
