For this tutorial, I will be adding an index.js file to the src folder, and this will be our entry point. Our file directory should look like this.

gcloud deployment-manager deployments create my-deployment --config qwiklabs.yaml

First, install Solaar to see the battery level on the taskbar

sudo apt-get install solaar

Host Multiple WordPress Sites behind Nginx Proxy

With the following “Docker recipe”, you will set up a Docker node running separate WordPress installation on two domains or subdomains. This setup is pretty much production ready, with:

nginx reverse proxy by Jason Wilder that automatically routes traffic to new containers that are created with the VIRTUAL_HOST=sub.domain.com environment variable. This nifty container performs a similar function to Traefik or HAProxy, but it is amazingly simple to use.
letsencrypt-nginx-proxy-companion by Yves Blusseau that obtains an SSL certificate from Let’s Encrypt, the free Certificate Authority, when you specify the LETSENCRYPT_HOST and LETS_ENCRYPT_EMAIL environment variables on any application container (i.e. WordPress) that needs to be served over HTTPS. The companion even pings Let’s Encrypt every 90 days to automatically renew your certificates!
Of

	Regular expression cheat sheet for Varnish

	Varnish regular expressions are NOT case sensitive. Varnish uses POSIX
	regular expressions, for a complete guide, see: "man 7 regex"

	Basic matching:
	req.url ~ "searchterm"
	True if req.url contains "searchterm" anywhere.

	req.url == "searchterm"
