Infra tools

This repo contains Infra as Code along with the tools to use.

Workspace

It is a custom docker image that contains all the tools you might need to use this repo.

Requirements

  • Working docker
  • Your linux user is able to run docker commands without sudo
Network connectivity

For ansible to work your host needs direct network connection with the internal azure virtual networks. You can use openvpn connection for that or run this container on a host in an azure vm. Or use ssh passthrough for all IPs as shown in Tune your ~/.ssh/config for openvpn.

Image content

  • kubectl
  • ansible /w libs
  • azure libs and cli
  • packer
  • terraform
  • terragrunt
  • packer
  • some default software (curl, tar, mc, etc...)

Features

Home dir passthrough

The user you start the container with is going to be created inside the container. And you have your home dir mounted inside the container.

SSH keys passthrough

As long as your home dir is mounted all your keys in ~/.ssh/ directory are effective. But the most important that your ssh-agent keys are passed through.

Please use keepass with ssh-agent and don't store you keys as files.

Usage

Run this script to jump inside: ./workspace/start.sh

In case the Dockerfile were updated use the command: ./workspace/start.sh build

Use ./workspace/start.sh build --no-cahce if you get some 404 while downloading packages and failed build.

SSH

Tune your ~/.ssh/config

Host *
# Avoid server key checking
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null
# Use your ssh keys on remote hosts without transfering them
  ForwardAgent yes
  AddKeysToAgent yes
# Misc...
  SendEnv LANG LC_*
  HashKnownHosts yes
  GSSAPIAuthentication yes
  ServerAliveInterval 100

Terraform

Terragrant is installed. It is a nice wrapper for terraform.

Easy targeting using regexp pattern

tfp apply -pattern=.*vm_02.*

Use tfp command instead of terragrunt. It is available inside the container. Originally I got it from here : https://github.com/schneidexe/tfp
