Since CloudFlare acts as a reverse proxy, all connections now come from one of CloudFlare’s IP addresses. and as @codinghorror
To fix this issue:
Add cloudflare.template.yml
to the bottom of the templates: section in your app.yml file.
Historical version of instructions
So here is the instruction :
(see CloudFlare official document )
cd /var/docker
./launcher ssh enter
cd /etc/nginx/
vi nginx.conf
Type A
Add these code between http block
set_real_ip_from 199.27.128.0/21;
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 141.101.64.0/18;
set_real_ip_from 108.162.192.0/18;
set_real_ip_from 190.93.240.0/20;
set_real_ip_from 188.114.96.0/20;
set_real_ip_from 197.234.240.0/22;
set_real_ip_from 198.41.128.0/17;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 104.16.0.0/12;
set_real_ip_from 2400:cb00::/32;
set_real_ip_from 2606:4700::/32;
set_real_ip_from 2803:f800::/32;
set_real_ip_from 2405:b500::/32;
set_real_ip_from 2405:8100::/32;
real_ip_header CF-Connecting-IP;
Your nginx.conf file should look like this:
http
{
set_real_ip_from 199.27.128.0/21;
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
......
real_ip_header CF-Connecting-IP;
........
}
Type ESC >> :wq >> Enter
Test nginx config
nginx -t
If you see this line nginx: configuration file /etc/nginx/nginx.conf test is successful
, your nginx configuration file is OK.
Restart nginx to take effect:
service nginx restart
exit
@sam @codinghorror can you help me to add this as a template?
