How To Create Docker Containers Running Memcached

https://www.digitalocean.com/communi...ning-memcached

Introduction

For the majority of web applications, it is extremely rare to find the CPU being the culprit for the dropped HTTP requests or choking the web server hosting them. It usually is an under-engineered setup with no caching layer involved, eating up all the resources of the backend data store (i.e. your database of choice).
Memcached - which by now should need no introduction - can increase the performance of your application deployment stack greatly without making any amendments to your available resources (enabling you to squeeze every last bit of its juices).
In this DigitalOcean article, especially keeping in mind those who host multiple web applications (e.g. multiple WordPress instances, Python Applications, etc.), we are going to create docker images to quickly start running (on-demand) Memcached containers which can be operated individually. These containers, kept and secured within their own environments, will work with the application being hosted to help them get better and faster.
