# Docker Container Basics

## Overview

This skill provides automated assistance for docker container basics tasks within the DevOps Basics domain.

## When to Use

This skill activates automatically when you:
- Mention "docker container basics" in your request
- Ask about docker container basics patterns or best practices
- Need help with foundational devops skills covering version control, containerization, basic ci/cd, and infrastructure fundamentals.

## Instructions

1. Provides step-by-step guidance for docker container basics
2. Follows industry best practices and patterns
3. Generates production-ready code and configurations
4. Validates outputs against common standards

## Examples

**Example: Basic Usage**
Request: "Help me with docker container basics"
Result: Provides step-by-step guidance and generates appropriate configurations


## Prerequisites

- Relevant development environment configured
- Access to necessary tools and services
- Basic understanding of devops basics concepts


## Output

- Generated configurations and code
- Best practice recommendations
- Validation results


## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| Configuration invalid | Missing required fields | Check documentation for required parameters |
| Tool not found | Dependency not installed | Install required tools per prerequisites |
| Permission denied | Insufficient access | Verify credentials and permissions |

Overview

This skill helps you manage Docker container basics and common DevOps container workflows. I provide step-by-step guidance, generate practical Dockerfiles and run commands, and validate common configuration mistakes. Use it to learn, create, or troubleshoot foundational container tasks quickly.

How this skill works

I inspect your request for Docker container intents and then produce concrete commands, configuration snippets, and short validations. Outputs include Dockerfiles, docker run examples, troubleshooting checks, and brief best-practice explanations. I aim to produce production-ready patterns you can copy, adapt, and run locally.

When to use it

  • You need a simple, secure Dockerfile for an application
  • You want step-by-step instructions to build, run, or debug containers
  • You’re onboarding to Docker and need guided examples
  • You need quick fixes for common container errors or permission issues
  • You want validated configuration snippets for CI/CD or local development

Best practices

  • Keep Dockerfiles small: use appropriate base images and multi-stage builds
  • Run containers as a non-root user and limit capabilities
  • Minimize image layers and avoid installing dev tools in production images
  • Pin base image versions and use digests for reproducible builds
  • Expose only required ports and document environment variables

Example use cases

  • Generate a minimal Dockerfile for a Python web app with dependencies and a non-root user
  • Provide docker run commands and volume examples for local development
  • Diagnose a container startup failure and suggest likely fixes (missing env var, permission error)
  • Create a multi-stage build for compiling and packaging a Go service
  • Suggest CI steps to build, scan, and push a container image to a registry

FAQ

What prerequisites are required to use the guidance?

You should have Docker installed locally or on your target host, basic terminal access, and access to source code to build images.

Can you produce production-ready Dockerfiles?

Yes. I follow common production patterns: multi-stage builds, non-root users, pinned base images, and small runtime images, but you should review security and registry policies specific to your environment.
