Rails assets can be a bit of a challenge when compiled… The guides reccommend serving the assets from the NGINX server.
I am currently serving assets from the rails application to simplify deployments.
# config/environments/production.rb
config.public_file_server.enabled = true
This is how the assets are supposed to be configured in the nginx configuration file for the rails webserver public file. I believe this method is difficult to configure with Docker unless the
upstream puma {
server unix:///home/deploy/apps/appname/shared/tmp/sockets/appname-puma.sock;
}
server {
listen 80 default_server deferred;
# server_name example.com;
root /home/deploy/apps/appname/current/public;
access_log /home/deploy/apps/appname/current/log/nginx.access.log;
error_log /home/deploy/apps/appname/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri @puma;
location @puma {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://puma;
}
