docker-compose-standards

docker-compose-standards is a cursor rule for Cursor from abderrahimghazali/cursor-rules. It costs 4 tokens per session (911 once invoked), scanned A, original, MIT.

Rules for Docker Compose files, which describe the services and settings used to run several containers together. Containers are isolated environments used to run applications and their dependencies.

In plain words
What is it for?
Use them when reviewing Compose files for image tags, indentation, networks, resource limits, privileged mode, and other listed service configuration choices.
Why use it?
They reduce avoidable configuration problems such as unexpected image updates, excessive permissions, inconsistent formatting, missing resource limits, and outdated service-connection settings.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 A, and why

docker-compose-standards 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 1mo 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.

What it actually says

  1. **Omit the 'version' field**: Compose files are version-less by default.
     ```yaml
     services:
       web:
         image: nginx
     ```

  2. **Use consistent indentation**: Use 2 spaces for indentation.
     ```yaml
     services:
       web:
         image: nginx
     ```

  3. **Avoid 'links' key**: Use networks and service names for service communication.
     ```yaml
     services:
       web:
         image: nginx
         networks:
           - my-network
       db:
         image: mysql
         networks:
           - my-network
     networks:
       my-network:
     ```

  4. **Specify explicit image tags**: Prevent unintended updates by defining image tags.
     ```yaml
     services:
       web:
         image: nginx:1.21.0
     ```

  5. **Avoid privileged mode**: Do not use 'privileged: true'. Grant specific capabilities if necessary.
     ```yaml
     services:
       web:
         image: nginx
         cap_add:
           - NET_ADMIN
     ```

  6. **Define resource limits**: Prevent services from consuming excessive resources.
     ```yaml
     services:
       web:
         image: nginx
         deploy:
           resources:
             limits:
               cpus: '0.50'
               memory: '512M'
     ```

  Implementing these practices ensures secure, maintainable, and consistent Docker Compose configurations.

examples:

  • input: | version: '3' services: web: image: nginx links: - db privileged: true db: image: mysql output: | services: web: image: nginx:1.21.0 networks: - my-network deploy: resources: limits: cpus: '0.50' memory: '512M' db: image: mysql:5.7 networks: - my-network networks: my-network: metadata: priority: high version: 1.0

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.
