Recently we’ve started down the ElasticSearch/Kibana road and also had a handful of other node.js apps. Setting up access control for these was becoming a pain - especially with ES which doesn’t come with any authentication/security out of the box. General advice on the interwebs is to let upstream server handle authentication and SSL + basic auth is good enough.
sudo apt-get install nginx apache2-utilsApache2 utils is for generating the htpasswd file for use later.
There’s a few things to handle:
we want SSL offloading to happen
Each application is going to be set up as it’s own virtual host - so think app1.mydomain.com, app2.mydomain.com
All apps will be served on SSL. HTTP requests will be forwarded to HTTPS automatically.
You can create the password db with
htpasswd -c /etc/nginx/passworddb <username>
You’ll be asked to confirm a password for the user and you’re all set.
See the last one setting a few other server variables - X-Forwarded-For,
X-Forwarded-Host, X-Forwarded-Proto? You’ll need this if the app you’re
serving is written to be reverse proxy aware - in that case, it would
use these headers to generate any links in the html it generates (so
that it doesn’t return a document with
and instead returns
http://reverseproxyhost/path). If the app you’re
proxying doesn’t do this, then you’re in the realm of output content
rewriting (basically regex the output content and replace link - ughhh!)
