Woodpecker agent/server not compatible with Docker Engine v29+ (API 1.44+) – “client version 1.43 is too old” error

[NatMedrano]

Hi Woodpecker team,

I’m running Woodpecker CI (server and agent, latest images) on a system with Docker Engine v29.x. When starting the agent, I get the following error:

Error response from daemon: client version 1.43 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version

It appears the Woodpecker agent/server images are built with an older Docker Go SDK (API 1.43), which is not compatible with Docker Engine v29+ (which requires API 1.44+). Downgrading Docker Engine to v28.x resolves the issue, but this is not ideal for long-term maintenance.

Is there a plan to release new Woodpecker images built with a newer Docker SDK/API?
Is there a workaround or timeline for a fix?
Has this already been addressed in a recent or upcoming release?

Thank you for your work on Woodpecker!

The SDK is at v28 indeed:

woodpecker/go.mod

Line 20 in 640a4ed

github.com/docker/docker v28.5.2+incompatible

There's no newer version for it however 🤔 For gtihub.com/docker/cli we already use v29.

github.com/docker/docker is an alias for github.com/moby/moby and moby seems to already have a newer version

[anbraten]

moby/moby#51468

So we should migrate from docker/docker to moby/moby?

[anbraten]

Sounds like. Might just be sth we need to do carefully as I am not sure if the new docker / moby client version will work with older daemons which might be the default on several distros.

Tried to change it, but that gives me

go: go.woodpecker-ci.org/woodpecker/v3/pipeline/backend/docker imports
        github.com/moby/moby/api/types/container imports
        github.com/docker/docker/api/types/blkiodev: github.com/docker/docker/api@v1.53.0: parsing go.mod:
        module declares its path as: github.com/moby/moby/api
                but was required as: github.com/docker/docker/api

when running go mod tidy.

And I cannot really find usage docs for moby.
