Welcome to DOTT.

This repository contains an API skeleton where you can add your code, choose the language of your preference.

• Demonstrate you have great coding and operation skills, no matter which technology stack is used.

• This is not an exam, this is more a task that has been assigned to you, so you can ask us at anything, anytime.

• Communication is important, if you don't have technical problems make sure to share your progress.

You need to complete a functionality in our API that provides some help to the networking team.

The API has 3 missing endpoints, the first endpoint converts Subnet Mast to CIDR format, the second endpoint return the CIDR value of a given Subnet Mask and finally the third endpoint simply validates an IPv4.

e.g.

curl localhost/cidr-to-mask?value=24
{
  "function": "cidrToMask",
  "input": "24",
  "output": "255.255.255.0"
}

curl localhost/mask-to-cidr?value=255.255.0.0
{
  "function": "maskToCidr",
  "input": "255.255.0.0",
  "output": "16"
}

curl localhost/ip-validation?value=255.255.0.0
{
  "function": "ipv4Validation",
  "input": "255.255.0.0",
  "output": true
}

• Define a CI pipeline.
• The pipelines must be checked in code (Jenkinsfile or Scripts).
• Automate your tests every time a change is pushed to the repository.
  • Avoid buggy code to be deployed.

• Define your CD pipeline.
• Deploy to your Production Environment based on your defined strategy.
• Manage stage as production.
• Deploy to your Testing Environment before deploying to stage or production.
• Deploy with no downtime in production.

• Complete the following endpoints.

• /mask-to-cidr?value=<VALUE>
• /cidr-to-mask?value=<VALUE>

• The following endpoint is not required for this phase.

• /ip-validation?value=<VALUE>

• Make sure your tests are passing
• Add missing tests
• You should pick one from a list of available languages.
  • Python
  • Go
  • Java
  • NodeJS
  • Ruby

You will have access to the following:

• AWS EC2 Insance

• You will be given a dedicated machine for your task. You should recieve the following:
  • IP of the EC2 instance
  • Access keys / .pem file

• Docker can be integrated with Jenkins, in a job you could use this command to build an image

 docker build -t my-image:some-tag .

• You will need to push data to a remote docker registry.
