[Bug]: AppApi deployment no longer works with Docker 29 #712
Description
⚠️ This issue respects the following points: ⚠️
- This is a bug, not a question or a configuration/webserver/proxy issue.
- This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
- Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
- I agree to follow Nextcloud's Code of Conduct.
Bug description
After updating to Docker 29 deployment daemons no longer work for NC via HaRP or docker-socket-proxy. This is due to the well known API changes which have now been raised to 1.44 - NC uses 1.41
Errors:
Socket Proxy:
ClientException Client error:GET http://dockerproxy:2375/v1.41/_ping` resulted in a 400 Bad Request response: {"message":"client version 1.41 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer (truncated...)
Could not connect to Docker daemon via http://dockerproxy:2375/v1.41/_ping `
HaRP:
Deploy daemon "harp_proxy_docker" is not accessible by Nextcloud. Please verify its configuration
Steps to reproduce
- Go to /settings/admin/app_api
- Set up docker-socket-proxy or HaRP proxy
- Check /admin/logging
Expected behavior
Expect the Ex_Apps deployment to work but it doesn't due to logged failure.

I'll add the error, nothing was deployed normally, the error is below and just points to the api, so it made sense to roll out an update where the code was not normally messed up.

Having same issue with "client is too old".

@rageebm, @demiant165, you can add "min-api-version" into daemon.json to ease API version requirements.
Here's my config for example:

Hello, this a duplicate of this:
#709
nextcloud/HaRP#69
Problem will be fixed in the next release of Nextcloud

Hey,
Thank you. Yes - the same workaround works for Portainer and other effected apps also

Closing as resolved.
#797 made the version configurable via appConfig, so if someone ever need to pin a different version , you can override it without a code change:
occ config:app:set app_api docker_api_version --value v1.44
