[dba-VS] What is Docker

[Doug Murphy]

Interesting. From the youtube I can see promise. It would be nice if Windows
supported containers and I could put my commercial Access runtime in one to
run on other OS's without the hassle of VM installations.

Docker is a fabulous new tool allowing easy application deployment on
diverse platforms but caution should be taken. Below is one of the best
description of Docker Containers:

To allow a container to run on all major platforms a service/server can be
first installed (Microsoft is making their own portable service/server):

http://boot2docker.io

Containers are great because of their small image size, ability to be easily
copied and their absolutely static code. This is also their greatest
weakness. It should be noted that at best the developer should be rolling
their own Container images, from scratch and at worse off loading prebuilt
images from a very reliable sources. Casual use of Containers could be more
dangerous than the use of proprietary code:

the-age-of-containers.html

In summary Containers are a great technology but they should be crafted and
used with care.
