DevOps started out as "Agile Systems Administration". In 2008, Andrew Shafer did a talk called "Agile Infrastucture" addressing issues around involving more of the company in the same disciplines as programmers.

In 2009, Patrick Debois created "DevOpsDays" conference to help to bring it to light. However, it wouldn't begin to trend until about 2010, when people would begin to describe it as a standalone discipline.

Today, DevOps goes beyond just developers, systems administration and infrastructure, its about [dev, ops, agile, cloud, open source and business](https://blogs.the451group.com/opensource/2010/03/03/devops-mixing-dev-ops-agile-cloud-open-source-and-busi

How to remove unused Docker containers and images

  1. Delete all containers

     $ docker ps -q -a | xargs docker rm
    

-q prints only the container IDs -a prints all containers

Notice that it uses xargs to issue a remove container command for each container ID

  1. Delete all untagged images

On Infrastructure
-----------------
There is one system, not a collection of systems.
The desired state of the system should be a known quantity.
The "known quantity" must be machine parseable.
The actual state of the system must self-correct to the desired state.
The only authoritative source for the actual state of the system is the system.
The entire system must be deployable using source media and text files.
