Terraform, HashiCorp's infrastructure as code (IaC) tool, is a favorite among developers and system administrators for its simplicity and power in managing and provisioning data center infrastructure. However, as with any technology, there are complexities that arise as we go deeper. One such complexity is loading …

TL;DR Yes. Terraform does not care where the API lives. On-premises it talks to vCenter (vmware/vsphere), Proxmox VE (bpg/proxmox), libvirt/KVM (dmacvicar/libvirt), Canonical MAAS for bare metal (canonical/maas) or a Docker engine (kreuzwerker/docker), and the plan/apply/destroy loop is identical to AWS. The …

Today, we'll unravel a common hurdle that you might encounter while working with Terraform and AWS: Error creating IAM Role. MalformedPolicyDocument: Has prohibited field Resource This error can put a wrinkle in your cloud deployment process, but don't worry. I'm here to guide you through it, step by step. By the end …

TL;DR null in Terraform means "not set". Passing null to a resource argument is the same as omitting the argument; passing it into a string, a count or a for_each is an error. Replace it with coalesce(var.port, 8080) when the fallback is a plain value, with var.name != null ? var.name : …

One of the key features that sets Terraform apart is its modular architecture, enabling the reuse of code and fostering collaboration across teams. In this blog post, we'll dive deep into the concept of output variables in Terraform modules and explore how they can be leveraged as inputs for another module, enabling …

Greetings to all DevOps enthusiasts and cloud technology practitioners! In today's blog post, we'll delve deeper into one of the key components of infrastructure as code (IaC) - Terraform. More specifically, we'll discuss how to reference a resource created by a Terraform module. This capability provides a more …

In this blog post share with you another fascinating aspect of Terraform - escape sequences. I remember when I first learned about escape sequences, and the moment it all clicked was magical. So, let's get ready to dive in! Just like in any language, escape sequences in Terraform are our way of communicating …

Introduction Docker has become an indispensable tool in modern software development, offering the ability to package applications and their dependencies into lightweight containers. However, if you're like me, you may have encountered a puzzling situation where your Docker container unexpectedly stops after running the …

Navigating the intricacies of Amazon Web Services (AWS) can be a complex task. Even seasoned developers working with Infrastructure as Code (IaC) tools like Terraform and CloudFormation may occasionally face frustrating obstacles. A common stumbling block arises from conflicts in Virtual Private Cloud (VPC) settings, …

TL;DR Detach without stopping: press Ctrl-P, then Ctrl-Q. Docker prints read escape sequence, docker attach exits with code 1, and the container keeps running. It only works when the container has a TTY - started with docker run -it or -dit. On a container started with -d only, Ctrl-P Ctrl-Q is just two bytes, and …
