Amazon Elastic Beanstalk の Node.js コンテナの中身（２）

リバースプロクシに nginx を指定した場合は、以下の設定で nginx が実行されます。

/etc/nginx/nginx.conf

# Elastic Beanstalk Managed

# Elastic Beanstalk managed configuration file
# Some configuration of nginx can be by placing files in /etc/nginx/conf.d
# using Configuration Files.
# http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/customize-containers.html
#
# Modifications of nginx.conf can be performed using container_commands to modify the staged version
# located in /tmp/deployment/config/etc#nginx#nginx.conf

# Elastic_Beanstalk

ほとんどチューニングはされていないようです。また、websocket を利用する場合は、設定を調整する必要があります。
