terraform VS crossplane

Claude also created the IAC for deploying the app on Hetzner, using Terraform as the configuration tool. I only had to provide my Hetzner API key for VPS resource provisioning and my Cloudflare API key for domain name DNS entry management. 🌐

Terraform Installed: Download and install Terraform from the website: https://www.terraform.io/

Terraform is an infrastructure as code tool that replaces the ClickOps method of defining, deploying, and managing infrastructure locally, on-premises, or in the cloud. Its declarative method of defining infrastructure lets you focus on the target state of the infrastructure rather than the steps needed to achieve that state, which makes managing infrastructure easier.

Terraform and Pulumi automate the provisioning of cloud resources. IaC ensures consistency and eliminates manual errors when setting up infrastructure.

As part of the task, I also needed to build the necessary infrastructure in AWS. The client organization primarily relied on “click-ops,” manually configuring resources through the AWS Management Console, and had not yet embraced Infrastructure as Code (IaC). Since we wanted to introduce IaC to streamline processes, I asked my boss if they had a preferred tool, such as Terraform, AWS CDK, or Pulumi. Their response was vague: “Any tool will do.”

Terraform

HashiCorp Terraform and Vault form a powerful combination in the DevSecOps landscape, embedding security into infrastructure provisioning and secrets management.

Automate Add-on Management: Kubernetes Operators and Infrastructure-as-Code (IaC) tools like Terraform reduce manual effort by automating add-on lifecycles and updates.

Crossplane

The most obvious alternative to Pulumi is Terraform. But hey, keep an eye out for OpenTofu, an upcoming open-source alternative following a BSL license change. Crossplane is another alternative for those who enjoy building infrastructure using Kubernetes CRDs. Check out more details below.

did anyone adopt in production https://crossplane.io ?

In the overall scheme of things , look at services like backstage.io , crossplane.io and opslevel.com to get ideas. This is not necessarily an endorsement of the services. If all you want is to handle cloud resources and that's it, Terraform can be enough with what ever flavor of web technologies you and your team are comfortable with and can support it along the way. Doesn't take much to create a js based website to collect data from a form, or use other means to collecting data as long as its recorded and transparent for accountability.

XRs are written in a fully declarative manner. And when I am building my XR from underlying managed resources provided by some crossplane provider I need to parametrize resources, use conditionals and create arrays of resuorces The issues of declarativeness in the world of automation are well known- we typically resort to some form of templating and we invent some imperative expressions into that templating language/format. This is currently not very well supported with Crossplane however Crossplane team realizes this issue and they are conteptualizing solution here

I have an idea for a project that would interface with Crossplane. The project has some code that would save tons of time if I could use it directly in my project, but it is located in the internal directory. I can't import the modules directly, but the project is open sourced under an Apache 2.0 license, so the code itself is available for use under that license.
