Continuous Delivery Using Docker And Ansible

Continuous Delivery Using Docker And Ansible

Continuous Delivery
Release Often
Release Faster
Great Reliable

Continuous Delivery workflow/pipeline

With which we can Test,Build,Release,& Deploy a simple application.

Application will be of any technology ex:python based.

The work flow will be Based upon using docker & docker-compose which is a emerging technology. With a goal to release our application as docker image.

So that it can be tested, building application artefacts, creating docker-release images, and running acceptance test, by external functionality, and finally publish docker image.

First we can run it locally, & then set in popular jenkins continuous delivery system, we will configure integration with GitHub, allowing continuous delivery work flow to be triggered on each application source code commit.

Assuming application passes all unit,integration & acceptance tests. Our pipeline will release images to docker hub, which will deployed to Aws with ansible using IAAC(S) approach with aws cloud formation and leveraging ec2 container service for running docker container is production.

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sane defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install –save` afterwards to install a package and
save it as a dependency in the package.json file.
