coolify-image-app

coolify-image-app is a skill for Claude Code from KhaledSaeed18/dotclaude. It costs 51 tokens per session (1,025 once invoked), scanned B, original, MIT.

A guide for creating a Coolify application that runs a prebuilt container image from a registry. A container image is a packaged application that a server can run.

In plain words
What is it for?
Use it to add or repair a Coolify application, configure its domain and health check, set resource limits and environment values, or connect a deployment pipeline through the Coolify API.
Why use it?
It defines the link between a delivery pipeline and the production server, reducing configuration mistakes around image tags, health checks, domains, limits, and environment settings.

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 B, and why

coolify-image-app scanned grade B with 2 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 11d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

C=$(sudo docker ps --filter label=coolify.resourceName=<app> --format '{{.Names}}' | head -1)

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Coolify rejects shell operators (`&&`, `|`, `;`) in the health command, and the runtime image has no curl: the probe must be a plain binary call. Number inputs sometimes do not take a typed value; press Enter inside the

How it starts

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

A Coolify application of type Docker Image is the contract between the pipeline and the server: the pipeline moves one field (the image tag) and asks for a deploy; Coolify does the rolling update behind one domain with the container's own probe as the gate. Configure it once, exactly, and let every later deploy be an API call.

Hard rules: never break these

  • Creating or saving a Coolify resource is a production action. Confirm with the owner before creating, deploying, changing domains or deleting anything, unless they already authorised it for this task.
  • Never publish host ports and never set a custom container name. Port mapping bypasses the firewall; a fixed name breaks rolling updates.
  • The image must exist before the first deploy. Push :main from the pipeline (or a manual run) first; Coolify cannot build a Docker Image app.
  • Never type or print a token or secret. The owner creates API tokens and pastes secrets; you prefill forms and give click-by-click steps.
  • Verify every save by reloading. Coolify's forms sometimes accept input without persisting it; reload the page and read the value back before moving on.

Step 1: Gather the facts

From the repo and the coolify-vps-baseline record: project and environment names, the image reference (ghcr.io/<owner>/<repo>), the container port, the exact domain, the health probe command the image ships (node healthcheck.js or similar), the memory budget, and which environment variables are runtime (build-time ones are baked into the image and must not be set here).

Step 2: Create the application

Coolify UI, the project's environment, New resource, Docker Image: image name without a tag, tag main, Create application. Note the application UUID from the URL; the pipeline needs it.

Step 3: Configure, tab by tab

Tab Set Why
General Name <app>; Domains https://<domain> only, delete the sslip.io one; Port <port>; no port mappings; no custom name one router, one domain, no host ports
Healthcheck Type Container command; command node healthcheck.js; interval 30, timeout 5, retries 3, start period 15; then Enable and confirm the modal the container, not the proxy, decides readiness
Resource Limits Memory 512m (or the budget); leave CPU one runaway app cannot take the host
Environment Variables runtime variables only; mark secrets as such build-time values are already in the image
Rollback nothing to set; this is where an earlier tag is redeployed the rollback path

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.

coolify-image-app is a skill published in the GitHub repository KhaledSaeed18/dotclaude (5 stars, last pushed 2d ago), licensed MIT. It adds 51 tokens to every session and 1,025 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-05.
