Template terraform provider for darwin arm

Provider registry.terraform.io/hashicorp/template v2.2.0 does not have a package available for your current platform, darwin_arm64

why

The templatefile function only works with files. If you're working with files then switch to templatefile.

The hashicorp/template provider's template_file data source works with template strings and files (converted to strings) but was archived/deprecated before creating an arm release forcing people to look into other options if using Apple M1 (based on ARM).

#!/bin/bash
# Usage:
#   ./find-region-of-instance-id.sh i-snip

aws ec2 describe-regions --query 'Regions[].RegionName' --output text | tr '\t' '\n' | tac | while read region; do
  output=`aws --region $region ec2 describe-instances --instance-ids $@ --query 'Reservations[].Instances[].InstanceId' --output text 2>/dev/null || true`

Get terraform version from tfstate

This returns the tfstate version from the tf state

Only useful if a pre-0.14 version of terraform is required to apply and it's too difficult to upgrade to the latest.

README

Find non arm based apps running on your m1 using system_profiler. This helps find out if an intel based app is running instead of a universal app.

Using this technique, I found out that IT had accidentally installed x86 slack and x86 chrome. I replaced those with the universal ones for better performance.

Sample output of the attached shell script

$ wget https://gist.githubusercontent.com/nitrocode/7ab3e9229a6bce66b73d59fc1970eec8/raw/m1_applications_not_universal.sh

Upgrade Terraform

• If using an arm instance, versions before 1.0.2 may cause intermittent issues so some commands will have to be repeated if they fail.
• Before each upgrade, the required_version may need to be updated
• After each upgrade, a terraform refresh may be needed

Prereqs

• Start with terraform that does not have any changes
• tfenv - brew install tfenv
