(Part 2/N) Terraform: Import Existing Resource

(Part 2/N) Terraform: Import Existing Resource

In this episode of the Terraform series, we continued from where we left off in the previous podcast. We created a Docker container, cloned the example repository, and initialized Terraform. We generated configuration using Terraform plan and imported a resource while modifying the configuration. We pruned the generated configuration and applied changes, handling destructive changes. We also troubleshooted and fixed errors along the way. Overall, we made progress in understanding Terraform and managing Docker containers using Terraform. In this second podcast of the Terraform series, Krish continues exploring the Terraform documentation and learning as he goes. He demonstrates how to modify the Terraform configuration by replacing placeholder values and making necessary changes to the config files. Krish also shares the commands he used, including Docker run, Docker PS, Terraform plan, Terraform apply, and Terraform show. He concludes the podcast by summarizing the progress made and inviting viewers to check out the next episode.

Takeaways

  • Terraform allows you to manage infrastructure using a common workflow

  • Importing resources into Terraform requires defining an import block and generating configuration

  • Destructive changes should be carefully managed and tested

  • Troubleshooting errors in Terraform requires understanding the configuration and resource dependencies Modifying the Terraform configuration involves replacing placeholder values and making necessary changes to the config files.

  • Commands like Docker run, Docker PS, Terraform plan, Terraform apply, and Terraform show are useful in the Terraform workflow.

  • The Snowpal platform offers APIs and SaaS products that can be used to power back-end systems and accelerate development processes.

  • Snowpal provides flexible options for using their products, including pay-per-use, monthly plans, and commercial licenses.

Implement menus: How hard can it possibly be?

Implement menus: How hard can it possibly be?

Say someone asked you to implement a "tiny" feature on an iPhone Mail App.Here's the (first part of the) requirement as Business provided it (to the dev team):- User can swipe right to left and when they do, 2 menu options should appear.- When you click on one of them, it should allow you to forward the email and when you click the other, it should archive it.Sounds simple enough?It should be simple till you get to the "the devil is in the detail" part. So, before I implement it, here are some questions I would have as a developer:- Can the user only swipe from right to left, or can they do vice-versa? And if they did that, what should happen?- If the user starts swiping but doesn't complete the action till they dragged it all the way to the very left, what should happen?- If the user swiped & performed an action but realized they were on the wrong item so wanted to undo, will they be able to do it? And if so, how?- Can they perform bulk actions? If so, is that a mutually exclusive action agnostic to the individual swipe?- After they swipe on one of the emails, say if they swiped on another. Will the subsequent action need to reset the state so the first one is now un-swiped?- Do we need to support multiple email accounts where each of them is rendered as a separate category? And if we did that, what should happen when a user swipes on one of the emails in each of those sections? Will that result in a reset of all states (of all other sections)?- And there's a few more I can think of off the top of my head but you get the idea.So, now, let me ask again:How simple is the design and implementation now? Did you have a change of heart and will you need to adjust your story points?"How hard can it possibly be?" :)#snowpal #projectmanagementKeep it simple. Keep it on https://snowpal.com. And just so that you can keep it simple, we do everything in our capacity to remove all the complexities. Rome was not built in a day as they say, and Snowpal 2.0 certainly wasn't either. We have built it brick by brick for your pleasure. Or, should I say, "swipe by swipe"? :)
