envoyをstandaloneで動かしてみる
# CentOS7へのインストール
# https://www.getenvoy.io/install/envoy/centos/
# config参考
# https://qiita.com/TokyoYoshida/items/8f614dc5051926bda605
# https://i-beam.org/2019/02/03/envoy-static-load-balancer/
# このコンフィグを、下記コマンドで動かそうとすると、
# $ envoy --config-yaml config.yml
# error initializing configuration '': Unable to convert YAML as JSON: config.yml
# と言われてしまったので、jsonに変換して動かす。
# $ envoy -c config.json
