ERROR: Docker instance "XXXXX" doesn't exist. about ufw-docker HOT 7 OPEN

可以给更多一些信息吗？

nextcloud 是运行在 Swarm 集群里面的话，需要用 sudo ufw-docker service allow nextcloud 80/tcp，可能需要看一下 nextcloud 的端口是监听在哪个上。

我用的是ubuntu snap的docker ，不只nextcloud ，ufw-docker找不到任何docker的容器。没有用Swarm 集群。
ufw-docker是从哪里读取docker的容器信息，估计snap方式的docker路径和常规docker路径不一样。

The problem is still relevant.

In my case I got this error message because the script could not find the docker executable. So the command failed (rather than not being able to find the docker instance).

@maryjeck @mad-max-traveller can you verify that docker is installed in one of these locations: PATH="/bin:/usr/bin:/sbin:/usr/sbin". In my case it was installed in /snap/bin. So adding that to path worked: 7cf3cde

@anuragpeshne I seem to have the same issue. On my machine, docker is installed in /snap/bin as well. How can I implement your fix? Thanks!

@JoeZUM : add that path to the PATH variable here: https://github.com/chaifeng/ufw-docker/blob/master/ufw-docker#L8

Hi @anuragpeshne, thanks! I found it and it worked. Thanks!
(Hadn't noticed your commit linked above, which also shows the location)
Best, J
