Introduction

As a Devops engineer contractor I tend to move quite often with the client contracts. To overcome the tedious task of setting up new development environments everytime; I setup this repos to make life easier for me. Hope you'll find useful.

• Docker image/build development environment includes:
• Python3
• Flask --> microframework
• python-terraform --> provides a wrapper of terraform command line tool
• python-terrascript --> generates terraform scripts using python.
• Terraform binary (defaults to v0.11.7 but can be overidden)
• Ansible (defaults to v2.5.0 but can be overidden)
• AWS CLI
• AWS Vault --> Profiles, MFA and roles switching capability

The packages are build using pip install if possible, further addons can be included during docker image build stage.

Installation

    git clone directory...
    cd directory
    python3 run.py -h
usage: run.py [-h] [-p PROFILE] [-i IMAGENAME] [-t TERRAFORMVERSION]
              [-a ANSIBLEVERSION] [--dockerAppUser DOCKERAPPUSER]
              [--installAnsible [INSTALLANSIBLE]]
              [--installTerraform [INSTALLTERRAFORM]]

optional arguments:
  -h, --help            show this help message and exit
  -p PROFILE, --profile PROFILE
                        Profile to use with aws-vault
  -i IMAGENAME, --imageName IMAGENAME
                        Docker image name
  -t TERRAFORMVERSION, --terraformVersion TERRAFORMVERSION
                        Terraform version
  -a ANSIBLEVERSION, --ansibleVersion ANSIBLEVERSION
                        Ansible version
  --dockerAppUser DOCKERAPPUSER
                        Docker OS App user
  --installAnsible [INSTALLANSIBLE]
                        Install ansible?
  --installTerraform [INSTALLTERRAFORM]
                        Install Terraform?

    python3 run.py  --dockerAppUser=devops --profile=dev
    ... snippep

Voila I've a same dev environment within a few minutes no matter where!

Note that $HOME/repos is where I checked out the git repos and can be seen in /repos in the docker image, where you can run terraform plan, etc.
