# ESPv2 extension configuration override.
#
# We do not need all the extensions, so we disable the ones we do not need. This
# reduces binary size, compile time, and attack vectors.

# This list overrides the default list controlling what extensions are compiled
# into envoy.
#
# See https://github.com/envoyproxy/envoy/tree/master/bazel/README.md
# and https://github.com/envoyproxy/envoy/blob/master/source/extensions/extensions_build_config.bzl
