Redirect from http to https, nginx - azure

Question

I am using this configuration down for nginx, i am using it for sidecar in azure, following this link
I can't figure it out what to change in the configuration to automatically redirect from http://domain to https://domain
# nginx Configuration File
# https://wiki.nginx.org/Configuration
# Run as a less privileged user for security reasons.
user nginx;
worker_processes auto;
events {
worker_connections 1024;
}
pid /var/run/nginx.pid;
http {
#Redirect to https, using 307 instead of 301 to preserve post data
server {
listen [::]:443 ssl;
listen 443 ssl;
server_name localhost;
# Protect against the BEAST attack by not using SSLv3 at all. If you need to support older browsers (IE6) you may need to add
# SSLv3 to the list of protocols below.

}
}
EDIT:
After the suggestion in the first answer it didn't worked, with the two blocks added it was like this:
# nginx Configuration File
# https://wiki.nginx.org/Configuration
# Run as a less privileged user for security reasons.
user nginx;
worker_processes auto;
events {
worker_connections 1024;
}
pid /var/run/nginx.pid;
http {
#Redirect to https, using 307 instead of 301 to preserve post data
server {
# catch HTTP requests for all valid HTTP `Host` header values
listen 80;
listen [::]:80;
server_name _; # list all your domain names here
# do redirection to HTTPS
return 301 https://$http_host$request_uri;
}
server {
# default server listening on port 80
# getting here means the HTTP `Host` header is missing or had an incorrect value
listen 80 default_server;
listen [::]:80 default_server;
# close the connection immediately
return 444;
}
server {
listen [::]:443 ssl;
listen 443 ssl;
server_name localhost;

Answer 1

I suggest to use two additional server blocks:
server {
# catch HTTP requests for all valid HTTP `Host` header values
listen 80;
listen [::]:80;
server_name domain www.domain; # list all your domain names here
# do redirection to HTTPS
return 301 https://$http_host$request_uri;
}
server {
# default server listening on port 80
# getting here means the HTTP `Host` header is missing or had an incorrect value
listen 80 default_server;
listen [::]:80 default_server;
# close the connection immediately
return 444;
}
Check this answer for additional details on this configuration.
Update
Checking the documentation link given by OP looks like the provided example uses nginx container listening on port 443 taking the TLS encryption job and proxying requests to some "Hello World" example container that listen on port 80. To do the HTTP to HTTPS redirection via the nginx container you can try to change the "Hello World" example container listening port to 8080 and made nginx proxying the incoming requests to that port instead of port 80. Try the following configuration:
nginx.conf
# nginx Configuration File
# https://wiki.nginx.org/Configuration
# Run as a less privileged user for security reasons.
user nginx;
worker_processes auto;
events {
worker_connections 1024;
}
pid /var/run/nginx.pid;
http {
#Redirect to https, using 307 instead of 301 to preserve post data
server {
# catch HTTP requests for all valid HTTP `Host` header values
listen 80;
listen [::]:80;
server_name _; # list all your domain names here
# do redirection to HTTPS
return 307 https://$http_host$request_uri;
}
server {
# default server listening on port 80
# getting here means the HTTP `Host` header is missing or had an incorrect value
listen 80 default_server;
listen [::]:80 default_server;
# close the connection immediately
return 444;
}
server {
listen [::]:443 ssl;
listen 443 ssl;
server_name localhost;
