How to Force HTTPS on AWS Elastic Beanstalk - amazon-web-services

Question

What is the best way to force http to https with Elastic Beanstalk that has a Nginx Load Balancer? Https works for the application with the certificate I received from the AWS Certificate Manager, I just want it to make sure that https is always used. Seems like something that should already be built in to AWS. Any help is appreciated.

Create a file that ends with .config in your ebextensions and add the following to it
files:
/etc/nginx/conf.d/proxy.conf:
owner: root
group: root
mode: "000644"
content: |
upstream nodejs {
server 127.0.0.1:8081;
keepalive 256;
}
server {
listen 8080;
if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
set $year $1;
set $month $2;
set $day $3;
set $hour $4;
}
access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
access_log /var/log/nginx/access.log main;
location / {
set $redirect 0;
if ($http_x_forwarded_proto != "https") {
set $redirect 1;
}
if ($http_user_agent ~* "ELB-HealthChecker") {
set $redirect 0;
}
if ($redirect = 1) {
return 301 https://$host$request_uri;
}
proxy_pass http://nodejs;
proxy_set_header Connection "";
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
gzip on;
gzip_comp_level 4;
gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
}
/opt/elasticbeanstalk/hooks/configdeploy/post/99_kill_default_nginx.sh:
owner: root
group: root
mode: "000755"
content: |
#!/bin/bash -xe
rm -f /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf
service nginx stop
service nginx start
container_commands:
removeconfig:
command: "rm -f /tmp/deployment/config/#etc#nginx#conf.d#00_elastic_beanstalk_proxy.conf /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf"
