cloudformation-guard VS delta

If you now use these services to fix the infrastructure findings, a drift occurs that is not always easy to fix. It is better to check for possible problems before the actual deployment. This approach is called “Shift-Left”. This can be done with the package cdk-validator-cfnguard. It's based on the CloudFormation Guard package.

AWS Config rules allow you to determine if a resource is compliant or not. Previously when you wanted to do custom checks you needed to write AWS Lambda functions to validate the configuration of a resource. Since Aug 2, 2022 you have the ability to use cfn-guard rules to achieve the same.

In my previous blog, How do you prove that your infrastructure is compliant. I explained how you can prove your infrastructure is compliant using CloudFormation Guard. But, how do you write those rules? And even more important, how do you test your rules? If you look at the repository CloudFormation Guard. You will notice that the project itself offers a testing framework. Alright! Let’s build a ruleset and write some tests for it!

When you use CloudFormation Guard in combination with CodeBuild Reports it makes it easier to see what rules have failed and keeps a history. When you have a solid set of compliance rules. It gives you a report that you can use to prove that the build of the infrastructure was compliant. You are also able to prevent non-compliant code rollout in production.

AWS CloudFormation: can help with deploying compliant stacks. You can make sure that a stack is compliant by using AWS CloudFormation guard.

Currently, we're also exploring the brand new AWS Config rules backed by guard. Now you can write rules using guard which is a policy-as-code language. Here is some example of a Guard Rule which we are testing.

https://github.com/aws-cloudformation/cloudformation-guard is also very useful, but more so when you want to keep your templates consistent to standards.

Thanks for the difftastic & zoxide tips.

However, I've been using this git pager/difftool: https://github.com/dandavison/delta

While it's not structural like difft, it does produce more readable output for me (at least when scrolling fast through git log -p /scanning quickly

I'm currently waiting on the integration between Delta and Difftastic:

https://github.com/dandavison/delta/issues/535

Difftastic now has JSON output, whic should make it much easier to build this.

I'm surely in the minority here. I've been using Emacs for almost a decade now, but I just can't get into the Magit workflow. I've tried several times, but always end up going back to Git on the command line. I have dozens of aliases, shell integrations, a nice diff viewer[1], etc., and interacting with Git has become muscle memory. I can commit, cherry-pick, rebase, bisect, fix conflicts, etc., in a fraction of the time it would take me to navigate Magit's UI. I'm sure with enough practice, a Magit user could do this more quickly and efficiently, but honestly, with some custom-built porcelain, Git's UI is not so bad. Though this could very well be Stockholm syndrome after using it for such a long time...

For whatever reason, Magit's opinionated workflows never clicked with me. A part of it is the concern that it will do something weird to my repo that I'll then have to waste more time undoing manually. I usually don't trust sugary wrappers around tools. And another is the fact I don't use Emacs on all machines, and setting up Git on a remote system is just a matter of copying over my config and some shell integrations.

Also, on a more personal note, I find the cultish fanboyism whenever Magit is brought up slightly offputting. Does anyone have anything bad to say about it? No software can realistically be this infallible. :)

For looking at diffs I still prefer the command line though, and use delta to view diffs between commits or branches.
