Once an infrastructure repo has a few concerns in it (account hardening, the security baseline, the signing stack still to come) there’s a steady pressure to split them into separate stacks with separate state, and Terragrunt is right there …
Every infrastructure repo runs the same CI: lint the OpenTofu, scan it, validate it, plan, apply. The first repo, you write that .gitlab-ci.yml by hand. The second, you copy it. By the third, you’ve got three copies of the same pipeline …
Every CI gate job across the infrastructure repos reaches for the same pile of tools: OpenTofu, tflint, trivy, checkov, gitleaks, terraform-docs, the AWS CLI. Installing that pile per job is both slow and quietly dangerous, because nothing …
The OIDC post explained the handshake that lets a GitLab pipeline deploy to AWS with no stored key. This is the story of the first time I got it wrong, and spent an afternoon fixing the wrong thing. The error was a flat 403 from AWS, and …
go-tool-base’s VCS support has two halves that get confused for one. One half talks to forge APIs (GitHub, GitLab) for releases and pull requests. The other talks to the .git directory on disk: clone, history, diff, status. This post is …
Turning on GuardDuty and Security Hub gives you threat detection. It also gives you a firehose. And an alert system that dutifully forwards everything in that firehose isn’t monitoring, it’s a very efficient way of training your team to …
A botched version bump made me stop and actually look at where go-tool-base lived, and I didn’t much like what I saw. GitHub had spent months quietly falling over, and when Mitchell Hashimoto (GitHub user #1299, no less) publicly walked …
There are well-known community module libraries for AWS: Cloud Posse, the terraform-aws-modules collection, plenty more. Both terraform-aws-bootstrap and terraform-aws-security-baseline use almost none of them. Every sub-module is …
Bootstrapping the account got it ready: somewhere to store state, an identity to deploy as, enough for the next tofu apply to run. Ready is not the same as safe. An account with no audit trail, nothing watching it, and no considered way for …
A long-lived AWS access key, sitting in a CI system, is just about the single credential I’d most like to be rid of. It’s powerful, it never expires unless someone remembers to rotate it (nobody remembers to rotate it), and it lives in one …
