Preface

The shared unattended switch and interactive workflow are described in environment modes.

Setting Up Virtual Memory

TIP

Allocate some swap space to prevent your machine from crashing.

Unit conversion: Inputting 1024 results in 1G of SWAP - virtual memory. Virtual memory occupies disk space and is automatically utilized when the physical memory is insufficient. However, this leads to high IO usage and CPU performance overhead.

It is recommended to allocate virtual memory twice the size of your physical memory.

curl -L https://raw.githubusercontent.com/spiritLHLS/addswap/main/addswap.sh -o addswap.sh && chmod +x addswap.sh && bash addswap.sh

Environment Setup

bash <(wget -qO- https://raw.githubusercontent.com/oneclickvirt/podman/main/podmaninstall.sh)

For unattended installation:

export noninteractive=true
bash <(wget -qO- https://raw.githubusercontent.com/oneclickvirt/podman/main/podmaninstall.sh)

Variable	Description	Default
noninteractive	Skip interactive prompts when set to true	false
WITHOUTCDN	Disable CDN detection and acceleration when set to true	false
NEED_DISK_LIMIT	Enable btrfs container disk limits	n
PODMAN_INSTALL_PATH	Root Podman storage path, saved as graphroot in storage.conf	/var/lib/containers/storage
PODMAN_POOL_SIZE	Size of the btrfs loop pool, in GB	20
PODMAN_LOOP_FILE	btrfs loop image path	/opt/podman-pool.img
PODMAN_ROOTLESS_USER	Configure subuid/subgid mappings for this rootless user	unset
PODMAN_ROOTLESS_CREATE_USER	Create the user named by PODMAN_ROOTLESS_USER if absent	false
PODMAN_ROOTLESS_SUBUID_START	First rootless subuid	100000
PODMAN_ROOTLESS_SUBGID_START	First rootless subgid	100000
PODMAN_IPV6_SUBNET	Explicit routed public IPv6 subnet; it must exclude addresses assigned to the host	selected from a local prefix
NDPRESPONDER_SOURCE_URL	Git source used to build the responder if its image is unavailable or has the wrong architecture	https://github.com/oneclickvirt/ndpresponder.git

Uninstall Podman Environment

Remove the Podman environment, including all containers, images, networks and auxiliary files:

bash <(wget -qO- https://raw.githubusercontent.com/oneclickvirt/podman/main/podmanuninstall.sh)

The script asks for yes; removal is irreversible. For unattended removal, set noninteractive=true. FORCE_UNINSTALL=true is also accepted for compatibility.

Verify installation

podman ps -a

For long installations, use screen or tmux to avoid interruption when SSH disconnects.
