Simple procedure for raspi does not complete

[nembrinj]

Hello,

description

I followed the procedure described here (https://docs.opencloud.eu/docs/admin/getting-started/other/raspberry-pi/) to setup my pi (model 3b I know it is not powerful enough but it "should" work....). When I do

docker compose up

If provides the following errors:

1. a docker compose like error

traefik-1 | 2025-10-31T22:45:18Z ERR Failed to retrieve information of the docker client and server host error="Error response from daemon: client version 1.24 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version" providerName=docker

2. an admin password error

opencloud-1 | The password of service user admin has not been set properly in your config for idm. Make sure your /etc/opencloud config contains the proper values (e.g. by using 'opencloud init --diff' and applying the patch or setting a value manually in the config/corresponding environment variable).
opencloud-1 exited with code 1 (restarting)

Steps to reproduce:

1. follow the procedure described here https://docs.opencloud.eu/docs/admin/getting-started/other/raspberry-pi/
2. And watch the docker compose repeatedly crash
3. needless to say, the web interface leads to "404 page not found" error

Thank you in advance for the feedback. The software seems really promising and the install procedure looked easy enough.....

update: I am using trixie. I will try with a buster image and let you know

Which docker version are you using?

Note: the docker version from the distribution is often very outdated. Please use the official docker installation guide.

Please let me know if I should give you more feedback under trixie and then I'll test buster.

Hi

I solved the admin password issue by defining a password in the .env file.

But I am still stuck with the docker client version issue.

Here again the output of the docker version that says that I have a recent version (1.52). I tried changing the traefik image version from v2 to v3.6-rc1 but with not effect on the error.

Alternatively: would it make sense to install an older version of docker?

This is somehow weird. Maybe some old packages are present?

The official install guide gives some hints:

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

Hi

Thanks for suggesting this potential solution. However it does not remove anything, consistently to the instructions to download the get-docker.sh script (which I followed). See the trace below.

The docker client version mismatch error remains.

Note: since I intend to use opencloud only locally I have no domain name pointing to the pi but instead a raspi.local address, as mentioned here

https://docs.opencloud.eu/docs/admin/getting-started/container/docker-compose/docker-compose-base

Could this be the problem? If yes, the error message would be quite misleading...

Maybe this is related portainer/portainer#12925 (comment)

[nembrinj]

yes this does the trick !! thanks a lot for pointing it out!

Now I need to dive into the .env and docker-compose.yml to avoid the need of a domain name. I found this

I am looking forward to using opencloud!
