Preface

Two methods for provisioning containers.

Single Container Provisioning

• Creates a single Podman container
• Can configure a routed public IPv6 address after podman-ipv6 is configured during installation
• Supports x86_64 and ARM64 architecture servers

IPv6 network mode

podman-ipv6 uses a managed ULA bridge. A separate public address is attached as a routed /128 with NDP, rather than cutting a child subnet from the host's public /64 for Netavark IPAM. The host needs usable public IPv6 and the upstream must permit the corresponding NDP neighbor response.

Download Script

curl -sSLO https://raw.githubusercontent.com/oneclickvirt/podman/main/scripts/onepodman.sh
chmod +x onepodman.sh

Example

Supported variables for running:

./onepodman.sh <name> <cpu> <memory_mb> <password> <sshport> <startport> <endport> [independent_ipv6:y/n] [system] [disk_gb]

Currently supported system values:

• debian
• ubuntu
• alpine
• almalinux
• rockylinux
• openeuler

Default is debian if not specified.

./onepodman.sh ct1 1 512 MyPassword 25000 34975 35000 n debian 0

Example container information:

Attribute	Value
Container name	ct1
SSH username	root
SSH password	MyPassword
CPU cores	1
Memory	512MB
SSH port	25000
External/internal port range	34975 to 35000
System	debian
Request routed public IPv6	N
Disk size	Unlimited

Related Operations

List all containers

podman ps -a

Enter container

podman exec -it ct1 bash

Enter Alpine container

podman exec -it ct1 sh

Type exit to leave the container.

Delete container

podman rm -f ct1

View container logs

podman logs ct1

Batch Container Provisioning

• Multiple runs inherit configuration and generate sequentially
• Auto-increments container name (ct1, ct2, ...), SSH port, and public ports
• Container information recorded to ctlog file
• Recommended to run in screen to avoid SSH disconnection

Run

curl -sSLO https://raw.githubusercontent.com/oneclickvirt/podman/main/scripts/create_podman.sh
chmod +x create_podman.sh
./create_podman.sh

Query Batch Container Information

cat ctlog

Output format:

container_name ssh_port root_password cpu_cores memory_mb start_port end_port disk_gb

One line per container.

Remove All Containers and Images

podman ps -aq | xargs -r podman rm -f
podman images -aq | xargs -r podman rmi -f
podman volume prune -f
podman system prune -af
rm -rf ctlog

Restart All Containers After Host Reboot

Podman supports systemd integration. Generate auto-start service for a container:

# Generate systemd service for a specific container
podman generate systemd --name ct1 > /etc/systemd/system/container-ct1.service
systemctl enable container-ct1

Or manually start all stopped containers:

podman ps -aq -f status=exited | xargs -r podman start
