difference of lxc container and docker container¶

creating a lxc container will alloc a new partition from lvm(a new logic partition), create a root-fs and copy image into it, and the image is a zip file.
creating a docker container will mount docker image layers one by one into the host's fs

best way¶

best way of running docker in pve is probably install docker inner a lxc container

speed up docker installation¶

remove old¶

for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do apt-get remove $pkg; done

setup repository¶

apt-get update apt-get install ca-certificates curl gnupg install -m 0755 -d /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg sudo chmod a+r /etc/apt/keyrings/docker.gpg echo \ "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ tee /etc/apt/sources.list.d/docker.list > /dev/null

install¶

apt-get update apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

copy image to another host¶

docker save | bzip2 | ssh user@host docker load

fix problem 'modprobe: FATAL: Module fuse not found in directory /lib/modules/6.1.10-1-pve'¶

enable the Options of your container (Select the container on the left-hand side > Options > Features) and then enable FUSE

warn Just be aware that FUSE in LXC containers can cause some problems (no snapshots, no suspend backup, lower security since there is less containment).
