What is Overmind?

Overmind is a powerful tool for real-time impact analysis on Terraform changes. Overmind can identify the blast radius and uncover potential risks with overmind terrafrom plan before they harm your infrastructure, allowing anyone to make changes with confidence. We also track the impacts of the changes you make with overmind teraform apply, so that you can be sure that your changes haven't had any unexpected downstream impact.

Why Use Overmind?

• ☁️ Cloud Complexity: Terraform tells you what it's going to change, but not whether this change will break everything. Teams need to understand dependencies to properly understand impact.
• 👨‍🏫 Onboarding & Productivity: Due to the reliance on "tribal knowledge", expert staff are stuck doing approvals rather than productive work and newer staff take longer to become productive.
• 📋 Change Management Process: IaC and automation mean that changes spend substantially more time in review and approval steps than the change itself actually takes.
• 🔥 Downtime: Outages are not caused by simple cause-and-effect relationships. More often than not, downtime is a result of dependencies people didn't know existed.

How We Solve It?

🔍 Blast Radius: Overmind maps out all potential dependencies and interactions within your infra in realtime. Supports over 120 AWS resources and all Kubernetes.

🚨 Risks: Discover specific risks that would be invisible otherwise. Risks are delivered directly to the pull request. Make deployment decisions within minutes not hours.

Advanced Use

Passing Arguments

Overmind's overmind terraform plan and overmind terraform apply commands mostly just wrap the terraform that you already have installed, adding all of Overmind's features on top. This means that no matter how you're using Terraform today, this will still work with Overmind. For example if you're using a more complex command like:

terraform plan -var-file=production.tfvars -parallelism=20 -auto-approve

Then you would add overmind to the beginning, and your arguments after a double-dash e.g.

overmind terraform plan -- -var-file=production.tfvars -parallelism=20 -auto-approve
