// HeroPods Example: IPv4 Networking and Internet Connectivity
|
|
// ============================================================================
|
|
//
|
|
// This script demonstrates IPv4 networking functionality:
|
|
// - Bridge networking with automatic IP allocation
|
|
// - NAT for outbound internet access
|
|
// - DNS resolution
|
|
// - HTTP connectivity testing
|
|
//
|
|
// The container gets an IP address from the bridge subnet (default: 10.10.0.0/24)
|
|
// and can access the internet through NAT.
|
|
// ============================================================================
|
|
|
|
// Step 1: Configure HeroPods instance with IPv4 networking
|
|
// This creates a HeroPods instance with bridge networking enabled
|
|
!!heropods.configure
|
|
name:'ipv4_demo'
|
|
reset:false
|
|
use_podman:true
|
|
bridge_name:'heropods0'
|
|
subnet:'10.10.0.0/24'
|
|
gateway_ip:'10.10.0.1'
|
|
dns_servers:['8.8.8.8', '8.8.4.4']
|
|
|
|
// Step 2: Create a new Alpine Linux container
|
|
// Alpine is lightweight and includes basic networking tools
|
|
!!heropods.container_new
|
|
name:'ipv4_container'
|
|
image:'custom'
|
|
custom_image_name:'alpine_3_20'
|
|
docker_url:'docker.io/library/alpine:3.20'
|
|
|
|
// Step 3: Start the container
|
|
// This sets up the veth pair and configures IPv4 networking
|
|
!!heropods.container_start
|
|
name:'ipv4_container'
|
|
|
|
// Step 4: Verify network configuration inside the container
|
|
|
|
// Show network interfaces and IP addresses
|
|
!!heropods.container_exec
|
|
name:'ipv4_container'
|
|

// Show DNS configuration
|
|
!!heropods.container_exec
|
|
name:'ipv4_container'
|
|
cmd:'cat /etc/resolv.conf'
|
|
stdout:true
|
|
|
|
// Step 5: Test DNS resolution
|
|
// Verify that DNS queries work correctly
|
|
!!heropods.container_exec
|
|
name:'ipv4_container'
|
|
cmd:'nslookup google.com'
|
|
stdout:true
|
|
|
|
// Step 6: Test HTTP connectivity
|
|
// Use wget to verify internet access (ping requires CAP_NET_RAW capability)
|
|
!!heropods.container_exec
|
|
name:'ipv4_container'
|
|
cmd:'wget -O- http://google.com --timeout=5 2>&1 | head -n 10'
|
|
stdout:true
|
|
|
|
// Test another website to confirm connectivity
|
|
!!heropods.container_exec
|
|
name:'ipv4_container'
|
|
cmd:'wget -O- http://example.com --timeout=5 2>&1 | head -n 10'
|
|
stdout:true
|
|
|
|
// Step 7: Test HTTPS connectivity (if wget supports it)
|
|
!!heropods.container_exec
|
|
name:'ipv4_container'
|
|
cmd:'wget -O- https://www.google.com --timeout=5 --no-check-certificate 2>&1 | head -n 10'
|
|
stdout:true
|
|
|
|
// Step 8: Stop the container
|
|
// This removes the veth pair and cleans up network configuration
|
|
!!heropods.container_stop
|
|
name:'ipv4_container'
|
|
|
|
// Step 9: Delete the container
|
|
// This removes the container and all associated resources
|
|
!!heropods.container_delete
