Building a Dev Enviroment in Terraform in AWS (From More than Certified)

Created development environment using AWS and Terraform including a route table, internet gateway, security group, public subnet, and EC2 instance, using templates, provisioners, and key generation for remote access.

NEW Concepts Learned

  • aws_ami 
    • A data segment instead of resource that pulls an owner number, filters by name (with 

Userdata

Made it a template file, it bootstaps the instance as well as installing the docker engine.

AMI searcher in EC2 Console

Going to search the AMI in the Instance Launcher, then returning to EC2 console to search it for the owner number and other info.

ssh-keygen

I used PuTTy for previous keys.

Terraform’s homemade File function

For relative file paths for shorter access

The .tpl extension

Makes templates that map to certain sections of the main code. Usually using ${ }, but that’s also very module-esque, I feel. Call it with templatefile()

Provisioners

I think it’s using a EC2 instance terminal on your VS Code local setup, in tandem with SSH tools in VS Code with Remote -SSH. It shouldn’t be done normally, and should always run within another resource.

Terraform has a Console 😲

Say it in the tone of that one Tweet where the woman goes ‘Pokemon has a son?’

terraform.tfvars is processed by default

Connecting IoT Devices to a Registration Server (Packet Tracer, Cisco)

In Packet Tracer, a demo software made by Cisco Systems. It certainly has changed a lot since 2016. It's almost an Olympic feat to even get started with it now, but it does look snazzy. This is for the new CCNA, that integrates, among other things, IoT and Automation, which I've worked on here before. Instructions here . I don't know if this is an aspect of "Let's make sure people are paying attention and not simply following blindly", or an oversight - The instructions indicate a Meraki Server, when a regular one is the working option here. I have to enable the IoT service on this server. Also, we assign the server an IPv4 address from a DHCP pool instead of giving it a static one. For something that handles our IoT business, perhaps that's safer; Getting a new IPv4 address every week or so is a minimal step against an intruder, but it is a step. There are no devices associated with this new server; In an earlier lab (not shown), I attached them to 'H

Building, Breaking, and Building A CRM with Retool

 I like no- or low-code solutions to things. I've often wanted to simply push a button or move some GUI around and have the code implement itself.  I've thought about building something that's like a customer relationship management (CRM) system for keeping up with my network better than my little spreadsheet where I click links and then go like something. The general idea in this CRM Development is:  To have a GUI to add people to a NRM (Network Relationship Management).       Attach it to a database (MySQL is what I went with eventually using Amazon Relational Database service, but you can use PostGRES, and probably others).     Make sure components are connected to each other in the retool interface. This video is a good start. Watching the tutorial video, heard some SQL commands and went 'Oh no 😳" before going "Wait I know basic SQL", which is good, because you'll see.  When you get set up, there's a plethora of resources you can use -- Incl
