AIO - The 'nextcloud-aio-mastercontainer' container was not found

Using docker composer and getting this error when starting container. I triple-checked the composer yaml and can’t see anything wrong with the container name:

version: '3'
    image: nextcloud/all-in-one:latest
    restart: no
    container_name: nextcloud-aio-mastercontainer
      - nextcloud_aio_mastercontainer:/mnt/docker-aio-config
      - /var/run/docker.sock:/var/run/docker.sock:ro
#      - '80:80'
      - '11000:11000'
      - '8080:8080'
      - '8443:8443'
      - APACHE_PORT=11000
      - NEXTCLOUD_DATADIR=/home/ubuntu/nextclouddados
    image: containrrr/watchtower
    container_name: watchtower
      - /var/run/docker.sock:/var/run/docker.sock
    command: nextcloud
    name: nextcloud_aio_mastercontainer

Such a basic error and can’t get through it… urgh

Any help appreciated.

I don’t know how the detection of the container is done, but I thought of the fact I’m running docker with vfs storage driver… if that matter?


Hi, can you post the whole logs here?

Are you using docker swarm?

no, just docker compose. I’m hosting inside a lxd os container but that shouldn’t matter I think.

Hm… can you post the output of sudo docker ps --format "{{.Names}}" ?

it returns nothing

$ sudo docker ps --format "{{.Names}}"

ok, without sudo:

$ docker ps --format "{{.Names}}"

Does it work if you set this to restart: always ?

no. my understanding is that since it “thinks” the container has a different name it exits with code 1…
if I use restart:always it keeps trying and failing.

I see. The question is why that is the case. Can you post the output of
docker ps --format "{{.Names}}" again when it is in the startup loop due to restart: always?


$ docker ps --format "{{.Names}}"

Hm, this is weird.

Can you post the output of the following commands?

docker inspect nextcloud-aio-mastercontainer
docker info
docker ps --format "{{.Names}}" | grep "^nextcloud-aio-mastercontainer$"

docker inspect nextcloud-aio-mastercontainer

docker ps --format “{{.Names}}” | grep “^nextcloud-aio-mastercontainer$”


This is interesting

Ah I think I know what happened. Did you install normal docker first which is still running and then decided to install docker rootless afterwards? Apparently normal docker is still running which is mounted into the mastercontainer. However the container itself runs in rootless docker. Thus it obviously cannot find itself because it does not exist in normal docker but only in rootles docker.

Please follow all-in-one/ at main · nextcloud/all-in-one · GitHub if you want to run AIO with rootless docker.

I was also reading on that… didn’t do anything different, just installed docker from the shell like it says on the aio instructions…
curl -fsSL | sudo sh

I then followed the post install docker steps to add my user to sudo users and docker group so I don’t need to use sudo with all docker commands

hmmm but I did have to chmod to docker.sock bc I was having access denied errors
