# Example:
#   `log_level` setting -> `KONG_LOG_LEVEL` env variable

# DATASTORE CACHE
#------------------------------------------------------------------------------

# In order to avoid unnecessary communication with the datastore, Kong caches

# caching of such configuration entities.

# 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.
#
# Kong will resolve hostnames as either `SRV` or `A` records (in that order, and
# `CNAME` records will be dereferenced in the process).
# In case a name was resolved as an `SRV` record it will also override any given
# port number by the `port` field contents received from the DNS server.
#
# The DNS options `SEARCH` and `NDOTS` (from the `/etc/resolv.conf` file) will
# be used to expand short names to fully qualified ones. So it will first try the
# entire `SEARCH` list for the `SRV` type, if that fails it will try the `SEARCH`
# list for `A`, etc.
#
# For the duration of the `ttl`, the internal DNS resolver will loadbalance each
# request it gets over the entries in the DNS record. For `SRV` records the
# `weight` fields will be honored, but it will only use the lowest `priority`
# field entries in the record.

                                 # the local `resolv.conf` file will be used.
                                 # Port defaults to 53 if omitted. Accepts
