Nextcloud AIO admin interface with php error

I am facing an issue that i never encounter before.
Trying to deploy nextcloud-aio on an ubuntu CT (on proxmox) via ansible.

First i provision the LXC, then i install docker-ce within it, and then i deploy the nextcloud/all-in-one image with the correct parameters :

    - name: Deploy Nextcloud instance
        image: nextcloud/all-in-one
        name: nextcloud-aio-mastercontainer
        restart_policy: always
          - 8080:8080
          - nextcloud_aio_mastercontainer:/mnt/docker-aio-config
          - /var/run/docker.sock:/var/run/docker.sock:ro
          APACHE_PORT: "11000"
          APACHE_IP_BINDING: ""

The weird thing is as soon as i go to the AIO-ADMIN on port 8080, i have at the top of the page this warning :
Warning : Undefined array key 1 in /var/www/docker-aio/php/src/Docker/DockerActionManager.php on line 751

Everything seems working good, except that i have some performances issues.

Is there anything to be done ?

Please let me know how to provide you any logs or information
Thanks a lot

After some tests, just want to add some things :

  • when i deploy a container in proxmox (using ansible) with docker installed etc. and then i launch the docker run command :
sudo docker run --init --sig-proxy=false \
--name nextcloud-aio-mastercontainer \
--restart always \
--publish 8080:8080 \
--env APACHE_PORT=11000 \
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
--volume /var/run/docker.sock:/var/run/docker.sock:ro \

This works very well, no php issue !

  • But as soon as i launch docker nextcloud-aio, via ansible, i got php errors.
