ubuntu中Docker 容器正在运行，但未在 docker ps 中显示

ubuntu中查看docker ps发现内容为空，但是容器在运行

查看docker ps

root@hello:~# docker ps
CONTAINER ID   IMAGE                      COMMAND                  CREATED        STATUS          PORTS     NAMES

查看docker info

结果发现

 Docker Root Dir: /var/snap/docker/common/var-lib-docker

注意，这里是snap版的docker，常见的问题是apt版和docker版同时安装了，

查看sanp软件列表

hello@hello:/root$ snap list
Name    Version   Rev    Tracking       Publisher   Notes
core18  20220706  2538   latest/stable  canonical✓  base
docker  20.10.14  1779   latest/stable  canonical✓  -
snapd   2.56.2    16292  latest/stable  canonical✓  snapd

可以看到有一个sanp版的docker

查看apt列表

hello@hello:/root$ apt list --installed | grep 'docker'

可以看到也有一个apt版的docker

两个版本的docker安装上肯定有冲突，所以解决方案就是卸载掉snap版的docker后重启

#卸载snap版docker
sudo snap remove docker
#重启
reboot
