Started container with docker run, now it is not showing up in docker ps -a

Question

I started a docker container with docker run, like this:

docker run \
-d \
--name plex \
--restart unless-stopped \
--network=host \
-e TZ="<timezone>" \
-e PLEX_CLAIM="<claimToken>" \
-v <path/to/plex/database>:/config \
-v <path/to/transcode/temp>:/transcode \
-v <path/to/media>:/data \
plexinc/pms-docker

Link to GitHub.com/plexinc/pms-docker

The docker container is running, as Im able to access the port and service, but I can't seem to list the container when Im running sudo docker ps -a or sudo docker ps -aq or sudo docker ps --filter "name=plex"

I tried to run pstree, and got this output:

        │         └─20*[{dockerd}]

So it is clearly running in docker. How do I restart or rebuild this container when I can't seem to get the ID from docker ps -a? sudo docker stop plex or sudo docker restart plex does not work either.

Edit:

Sorry, did not include os and docker. Im running on Ubuntu server Ubuntu 18.10 (GNU/Linux 4.18.0-15-generic x86_64)

Docker version 18.09.1, build 4c52b90

Answer 1

To Just answer the question, there is also a way to identify the container id without using docker ps. You have to try deleting the image on which the container is created.

In your case you have to give docker rmi plexinc/pms-docker. If there is a container associated with this image, then you will get an error message like below:

Error response from daemon: conflict: unable to remove repository reference "plexinc/pms-docker" (must force) - container 92203921146d is using its referenced image f123as324ad

Here 92203921146d is your conatiner ID.

Answer 2

Had installed docker twice. Once with apt-get and once with snap.

Completely removed docker, both from apt and snap, and installed just using apt-get, and now the plex container is visible using docker ps -a.
