podman 容器的无根 systemd（无需 repalce 或 rm）

Question

如果每次都运行同一个容器，如何使用 systemd 设置 podman？ （即不是

podman run --replace

）

Answer 1

从 podman 检查获取 pidfile：

cd ~/
 
# container-mypodmancontainer.service must be re-generated if container-id changes
# prerequisite: podman container mypodmancontainer exists
mkdir -vp ~/.config/systemd/user/
cat > ~/.config/systemd/user/container-mypodmancontainer.service <<EOT
[Unit]
Description=Podman container-mypodmancontainer.service
Documentation=mydocs
Wants=network-online.target

PIDFile=$(podman inspect --format '{{ .PidFile }}' mypodmancontainer)
