How to Use Cdev

Since (cdev) is quite a powerful framework, it could be operated in several modes.

Deploy infrastructures from existing stack templates

This mode, also known as user mode, gives you the ability to launch ready-to-use infrastructures from prepared stack templates by just adding your cloud credentials and setting variables (like name, zones, number of instances, etc.). You don't need to know background tooling like Terraform or Helm, it's just as simple as downloading a sample and launching commands. Here are the steps:

  • Install cdev binary
  • Choose and download a stack template
  • Set cloud credentials
  • Define variables for the stack template
  • Run cdev and get a cloud infrastructure

Create your own stack template

In this mode you can create your own stack templates. Having your own template enables you to launch or copy environments (like dev/stage/prod) with the same template. You'll be able to develop and propagate changes together with your team members, just using Git. Operating cdev in the developer mode requires some prerequisites. The most important is understanding Terraform and how to work with its modules. The knowledge of go-template syntax or Helm is advisable but not mandatory.

The easiest way to start is to download/clone a sample template project like AWS EKS and launch an infrastructure from one of the examples. Then you can edit some required variables, and play around by changing values in the template itself.


Let's assume you are starting a new infrastructure project. Let's see how your workflow would look like.

  1. Define what kind of infrastructure pattern you need to achieve.

    a. What Terraform modules it would include (for example: I need to have VPC, Subnet definitions, IAM's and Roles).

    b. Whether you need to apply any Bash scripts before and after the module, or inside as pre/post-hooks.

    c. If you are using Kubernetes, check what controllers would be deployed and how (by Helm chart or K8s manifests).

  2. Check if there is any similar sample template that already exists.

  3. Clone the stack template locally.

  4. Apply.
