# Podman Module
Tools to work with containers using Podman and Buildah.
A clean, consolidated module for working with Podman containers and Buildah builders.
## Overview
This module provides **two complementary APIs** for Podman functionality:
1. **Simple API**: Direct functions for quick operations (`podman.run_container()`, `podman.list_containers()`)
2. **Factory API**: Advanced factory pattern for complex workflows and state management
### Key Features
- **Container Management**: Create, run, stop, and manage containers
- **Image Management**: List, inspect, and manage container images
- **Builder Integration**: Seamless Buildah integration for image building
- **Unified Error Handling**: Consistent error types across all operations
- **Cross-Platform**: Works on Linux and macOS
## Platform Support
@@ -9,114 +24,304 @@ Tools to work with containers using Podman and Buildah.
- **macOS**: Full support (requires podman installation)
- **Windows**: Not supported
## Basic Usage
## Module Structure
```v
#!/usr/bin/env -S v -n -w -enable-globals run
- **`factory.v`** - Main entry point with both simple API and factory pattern
- **`container.v`** - All container types and management functions
- **`image.v`** - All image types and management functions
- **`builder.v`** - Buildah integration for image building
- **`errors.v`** - Unified error handling system
import freeflowuniverse.herolib.virt.podman
import freeflowuniverse.herolib.ui.console
## API Approaches
console.print_header("PODMAN Demo")
### 1. Simple API (Quick Operations)
// Create a new podman factory
// install: true will install podman if not present
// herocompile: true will compile hero for use in containers
mut factory := podman.new(install: false, herocompile: false)!
// Create a new builder
mut builder := factory.builder_new(name: 'test', from: 'docker.io/ubuntu:latest')!
// Run commands in the builder
builder.run('apt-get update && apt-get install -y curl')!
// Open interactive shell
builder.shell()!
```
## buildah tricks
```bash
#find the containers as have been build, these are the active ones you can work with
buildah ls
#see the images
buildah images
```
result is something like
```bash
CONTAINER ID BUILDER IMAGE ID IMAGE NAME CONTAINER NAME
a9946633d4e7 * scratch base
86ff0deb00bf * 4feda76296d6 localhost/builder:latest base_go_rust
```
some tricks
```bash
#run interactive in one (here we chose the builderv one)
buildah run --terminal --env TERM=xterm base /bin/bash
#or
buildah run --terminal --env TERM=xterm default /bin/bash
#or
buildah run --terminal --env TERM=xterm base_go_rust /bin/bash
```
to check inside the container about diskusage
```bash
apt install ncdu
ncdu
```
## Create Container
For simple container operations, use the direct functions:
```v
import freeflowuniverse.herolib.virt.podman
import freeflowuniverse.herolib.ui.console
console.print_header("Create a container")
// List containers and images
containers := podman.list_containers(true)! // true = include stopped
images := podman.list_images()!
mut factory := podman.new()!
// Run a container
options := podman.RunOptions{
name: 'my-app'
detach: true
ports: ['8080:80']
volumes: ['/data:/app/data']
env: {'ENV': 'production'}
}
container_id := podman.run_container('nginx:latest', options)!
// Create a container with advanced options
// See https://docs.podman.io/en/latest/markdown/podman-run.1.html
mut container := factory.container_create(
name: 'mycontainer'
image_repo: 'ubuntu'
image_tag: 'latest'
// Resource limits
memory: '1g'
cpus: 0.5
// Network config
network: 'bridge'
network_aliases: ['myapp', 'api']
// DNS config
dns_servers: ['8.8.8.8', '8.8.4.4']
dns_search: ['example.com']
interactive: true // Keep STDIN open
mounts: [
'type=bind,src=/data,dst=/container/data,ro=true'
]
volumes: [
'/config:/etc/myapp:ro'
]
published_ports: [
'127.0.0.1:8080:80'
]
// Manage containers
podman.stop_container(container_id)!
podman.remove_container(container_id, force: true)!
podman.remove_image('nginx:latest', force: false)!
```
### 2. Factory API (Advanced Workflows)
For complex operations and state management, use the factory pattern:
```v
import freeflowuniverse.herolib.virt.podman
// Create factory (with auto-install)
mut factory := podman.new(install: true, herocompile: false)!
// Create containers with advanced options
container := factory.container_create(
name: 'web-server'
image_repo: 'nginx'
image_tag: 'alpine'
forwarded_ports: ['80:8080']
memory: '512m'
cpus: 1.0
)!
// Start the container
container.start()!
// Build images with Buildah
mut builder := factory.builder_new(
name: 'my-app'
from: 'ubuntu:latest'
)!
builder.run('apt-get update && apt-get install -y nodejs')!
builder.copy('./app', '/usr/src/app')!
builder.set_entrypoint('node /usr/src/app/server.js')!
builder.commit('my-app:latest')!
// Execute commands in the container
container.execute('apt-get update', false)!
// Open interactive shell
container.shell()!
// Seamless integration: build with buildah, run with podman
app_container_id := factory.create_from_buildah_image('my-app:latest', config)!
```
## future
## Container Operations
should make this module compatible with <https://github.com/containerd/nerdctl>
### Simple Container Management
```v
// List containers
all_containers := podman.list_containers(true)! // Include stopped
running_containers := podman.list_containers(false)! // Only running
// Inspect container details
container_info := podman.inspect_container('container_id')!
println('Container status: ${container_info.status}')
// Container lifecycle
podman.stop_container('container_id')!
podman.remove_container('container_id', force: true)!
```
### Advanced Container Creation
```v
// Factory approach with full configuration
mut factory := podman.new()!
container := factory.container_create(
name: 'web-app'
image_repo: 'nginx'
image_tag: 'alpine'
// Resource limits
memory: '1g'
cpus: 2.0
// Networking
forwarded_ports: ['80:8080', '443:8443']
network: 'bridge'
// Storage
mounted_volumes: ['/data:/app/data:ro', '/logs:/var/log']
// Environment
env: {'NODE_ENV': 'production', 'PORT': '8080'}
// Runtime options
detach: true
remove_when_done: false
)!
```
## Image Operations
### Simple Image Management
```v
// List all images
images := podman.list_images()!
for image in images {
println('${image.repository}:${image.tag} - ${image.size}')
}
// Remove images
podman.remove_image('nginx:latest', force: false)!
podman.remove_image('old-image:v1.0', force: true)! // Force removal
```
### Factory Image Management
```v
mut factory := podman.new()!
// Load and inspect images
factory.images_load()! // Refresh image cache
images := factory.images_get()!
// Find specific images
image := factory.image_get(repo: 'nginx', tag: 'latest')!
println('Image ID: ${image.id}')
// Check if image exists
if factory.image_exists(repo: 'my-app', tag: 'v1.0')! {
println('Image exists')
}
```
## Builder Integration (Buildah)
### Creating and Using Builders
```v
mut factory := podman.new()!
// Create a builder
mut builder := factory.builder_new(
name: 'my-app-builder'
from: 'ubuntu:22.04'
delete: true // Remove existing builder with same name
)!
// Build operations
builder.run('apt-get update && apt-get install -y nodejs npm')!
builder.copy('./package.json', '/app/')!
builder.run('cd /app && npm install')!
builder.copy('./src', '/app/src')!
// Configure the image
builder.set_workingdir('/app')!
builder.set_entrypoint('node src/server.js')!
// Commit to image (automatically available in podman)
builder.commit('my-app:latest')!
// Use the built image immediately with podman
container_id := factory.create_from_buildah_image('my-app:latest', config)!
```
### Build-to-Run Workflow
```v
// Complete workflow: build with buildah, run with podman
container_id := factory.build_and_run_workflow(
build_config: build_config,
run_config: run_config,
image_name: 'my-app'
)!
```
## Error Handling
The module provides comprehensive error handling with specific error types:
```v
// Simple API error handling
containers := podman.list_containers(true) or {
match err {
podman.ContainerError {
println('Container operation failed: ${err.msg()}')
}
podman.ImageError {
println('Image operation failed: ${err.msg()}')
}
else {
println('Unexpected error: ${err.msg()}')
}
}
[]podman.PodmanContainer{}
}
// Factory API error handling
mut factory := podman.new() or {
println('Failed to create factory: ${err}')
exit(1)
}
container := factory.container_create(args) or {
if err is podman.ContainerError {
println('Container creation failed: ${err.msg()}')
} else if err is podman.ImageError {
println('Image error: ${err.msg()}')
} else {
println('Creation failed: ${err.msg()}')
}
return
}
// Builder error handling
mut builder := factory.builder_new(name: 'test', from: 'nonexistent:latest') or {
println('Builder creation failed: ${err.msg()}')
return
}
builder.run('invalid_command') or {
println('Command execution failed: ${err.msg()}')
// Continue with fallback or cleanup
}
```
## Installation and Setup
```v
import freeflowuniverse.herolib.virt.podman
// Automatic installation
mut factory := podman.new(install: true)! // Will install podman if needed
// Manual installation check
mut factory := podman.new(install: false) or {
println('Podman not found. Please install podman first.')
exit(1)
}
```
## Complete Example
See `examples/virt/podman/podman.vsh` for a comprehensive example that demonstrates:
- Automatic podman installation
- Simple API usage (run_container, list_containers, etc.)
- Factory API usage (advanced container creation, builder workflows)
- Error handling patterns
- Integration between buildah and podman
- Cleanup and uninstallation
## API Reference
### Simple API Functions
- `run_container(image, options)` - Run a container with simple options
- `list_containers(all)` - List containers (all=true includes stopped)
- `list_images()` - List all available images
- `inspect_container(id)` - Get detailed container information
- `stop_container(id)` - Stop a running container
- `remove_container(id, force)` - Remove a container
