A set of docker image build-files for local software development purposes.

The primary motivation behind creating these docker images is to setup a cluster of light-weight docker containers to experiment with different server/cluster environments (as close to real production environment as possible) on local development machine.

Consider following software development scenarios as possible use-cases:

• Have a local dev server that you can ssh to like a remote server (just like a light-weight VM running your local machine instead of on the VirtualBox/AWS/Google Cloud etc.).

• You, as developer, have build a SaaS product, now you want to make sure that the product works as expected when it is run behind a load-balancer (e.g. HAProxy or similar products on your production servers).

• You want to run PostgreSQL in some cluster mode (for database replication, testing, hacking etc).

• Want's to create a data ingestion pipeline for Analytics or a cluster of servers needed for an inherently distributed software product e.g. HDFS, on your local machine.

• And, more.

Docker image from 'images/sshd' build-file works both as a stand-alone and base-image for creating other images (e.g. postgres, node, etc) in this git repository.

When you want to use 'images/sshd' image as a base-image for creating, let's say, postgres docker image, it should be named as 'ubuntu/sshd:16.04' (as it's referenced in postgres docker build-file with this image name) or update the reference to sshd image with your local docker image's name in 'images/(postgres|node)/Dockerfile' files.

Warning: These docker images are tailored specifically for local development purposes only as there are lots of packages installed which one don't want in production environment; therefore, don't use it on your production server without significant modification.
