Container Management

Use this skill when working with containers, Podman operations, or container-based workflows.

Activation Triggers

Activate this skill when the user mentions:

• Podman commands or container operations
• Docker/Containerfile creation
• Container networking or storage
• Image building or management
• Rootless container workflows
• Container security practices

Capabilities

This skill provides:

• Podman command assistance and best practices
• Containerfile/Dockerfile optimization
• Container networking and storage solutions
• Image building and management
• Security-focused container practices
• Multi-architecture container support

Available Tools

• podman: Primary container runtime (rootless by default)
• git: For Containerfile version control
• nvim: For editing Containerfiles and configs
• curl: For testing containerized services

Context Awareness

Directory Structure

• Look for Containerfile/Dockerfile in current directory
• Check for docker-compose.yml or podman-compose files
• Identify container-based project structures

User Environment

• Rootless containers are preferred
• Security-conscious approach
• CLI-focused workflows
• Integration with development environments

Common Operations

Container Lifecycle

• Building images from Containerfiles
• Running containers with proper security
• Managing container storage and networking
• Container debugging and troubleshooting

Image Management

• Multi-stage builds for optimization
• Registry operations (push/pull)
• Image security scanning
• Layer optimization

Development Workflows

• Development container setup
• Volume mounting for code
• Port forwarding for services
• Integration with Distrobox

Best Practices to Follow

• Use rootless containers by default
• Implement multi-stage builds for smaller images
• Follow principle of least privilege
• Use specific image tags, avoid 'latest'
• Implement proper health checks
• Optimize for security and performance
• Use non-root users in containers
