Describe the bug
There seems to be a version mismatch between the golang version used for building krakend in the Docker 2.7.0 release (devopsfaith/krakend:2.7.0) and the Go version used in krakend/builder version 2.7.0.

The krakend Docker release is built with Go version 1.22.2:

docker run -ti devopsfaith/krakend:2.7.0 version
KrakenD Version: 2.7.0
Go Version: 1.22.2
Glibc Version: MUSL-1.2.4_(alpine-3.18.6)

While the builder is using Go version 1.22.5:

docker run -it -v "$PWD:/app" -w /app krakend/builder:2.7.0 go version
go version go1.22.5 linux/amd64

Commands used
How did you start the software?

docker run -it -v "$PWD:/app" -w /app \
krakend/builder:2.7.0 \
go build -buildmode=plugin -o my-plugin.so .

And running krakend:

docker run -p "8080:8080" -v $PWD:/etc/krakend/ devopsfaith/krakend:2.7.0 run -c krakend.json run

Expected behavior
Succesful loading of the plugin

Yes, this is a major issue, as I can’t upgrade to version 2.7.0 of Krankend because the plugins generated with the 2.7.0 version of the builder won’t load.

[taik0]

We are aware of the issue. We are rebuilding the 2.7.0 binaries to use the latest builder.

[taik0]

Docker containers and packages are already updated to use the latest Golang version (1.22.5) and now matches the version used by the krakend-builder.
