Common Mistakes on r/docker
Avoid these pitfalls that get marketers banned or ignored.
Promoting orchestration over Docker basics
Many Docker users aren't using Kubernetes. Assuming everyone needs orchestration misses a large audience.
Instead
Know your audience: "For single-host: Docker Compose. For orchestration: here's how this extends to Kubernetes."
Not providing Dockerfile examples
Docker is hands-on. Abstract descriptions without working examples are hard to follow.
Instead
Include examples: "Here's the Dockerfile: [code]. Why each instruction: [explanation]."
Ignoring image size and build time
Image optimization is a common concern. Oversized images or slow builds are pain points.
Instead
Address optimization: "Image size: [MB]. Build time: [duration]. Optimization: [multi-stage, alpine, etc.]."
Security as afterthought
Container security matters. Running as root or ignoring best practices gets called out.
Instead
Include security: "Runs as non-root. Image scanning: [approach]. Secrets handling: [method]."
Closed-source container tools
Container ecosystem is heavily open-source. Proprietary tools without free tiers face resistance.
Instead
Offer open options: "Open source at [repo]. Enterprise features available for [additional needs]."
