gitops

A deployment model where Git describes the desired system and a controller inside the cluster continually makes the running system match it. The controller pulls changes from a repository instead of relying on people or pipelines to push commands to the cluster.

In plain words
What is it for?
Use it to organize application and deployment repositories, promote changes between environments, and manage Kubernetes deployments through pull-based reconciliation.
Why use it?
It gives deployment changes an audit trail and makes promotion and rollback repository changes. It also exposes configuration drift instead of allowing the cluster to quietly differ from its declared state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gitops scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GitOps

GitOps is not "we keep our YAML in Git." It is a specific operational model: a controller inside the cluster continuously pulls desired state from a repo and reconciles reality toward it, so the repo is not documentation of what was deployed — it is the only correct description of what should be deployed, and anything else is drift waiting to be corrected. That shift from push to pull is what makes the rest of the practice fall into place: audit trail, rollback, and promotion all become Git operations instead of pipeline scripts.

If the cluster state and the repo disagree, the cluster is wrong, not the repo.

1. Separate the app repo from the config repo

The repo where application code lives and the repo the reconciler watches should not be the same repo, and should almost never be the same commit. CI in the app repo builds an image, pushes it to a registry, and then makes a small, automated commit to the config repo bumping an image tag — it never touches the cluster directly. This split matters because it lets you reason about "what is deployed" by reading one small, low-churn repo instead of grepping application history, and it lets the config repo have its own review rules (e.g. required approval for prod) independent of code review norms. See ci-pipelines for the build side and artifact-management for where the image actually lives.

Done when: deploying a new version never requires a human to run a deploy command by hand.

2. Model environments as directories or branches promoted by merge

Represent each environment (dev, staging, prod) as its own path or overlay, and promote a change by merging or copying it forward — not by re-running a pipeline with a different target flag. A pull request from staging/ into prod/ is a promotion event with a diff, a reviewer, and a timestamp, which is a far stronger artifact than a Jenkins job log claiming the same thing happened. Kustomize overlays or Helm values-per-environment both work; what matters is that the mechanism of promotion is a Git operation everyone can see. See environment-management for how environments are defined and release-management for gating promotion on approvals or criteria.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gitops is a skill published in the GitHub repository arjunprabhulal/devops-skills (2 stars, last pushed 7d ago), licensed MIT. It adds 122 tokens to every session and 1,378 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
