Latest krakend/builder otel version mismatch with plugins

[Alberto Garcia Taravillo]

Hey,

I have a backend plugin that modifies or ignore the request that has to be made using some options.
The thing is I need to add opentelemetry so I don't lose traces after modifications. A problem with versions has appeared. 
Build is ok but when loading the plugins I receive the following error on krakend:
plugin was built with a different version of package go.opentelemetry.io/otel/internal

The plugin uses:

import( ... "go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp"

)

My plugin/go.mod

go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp v0.58.0

    go.opentelemetry.io/otel v1.33.0

opentelemetry-go-contrib/instrumentation/net/http/otelhttp/go.mod at zpages/v0.58.0 · open-telemetry/opentelemetry-go-contrib · GitHub
v 0.58 uses /otel:1.33

Checking the   krakend-ce/go.mod at v2.9.4 · krakend/krakend-ce · GitHub
uses

1. github.com/krakend/krakend-otel v0.9.1 ( krakend-otel/go.mod at v0.9.1 · krakend/krakend-otel · GitHub uses   go.opentelemetry.io/otel v1.33.0)
2. go.opentelemetry.io/otel/trace v1.33.0
   
   

So... clearly I'm missing something... 

images used in dockerfile:

FROM krakend/builder:2.9.4

FROM krakend:2.9.4 did you experiment something similar? Are you able to reproduce the mismatch with latest version?

How can I resolve the conflict? Thanks.

Hi Alberto!

You can use the check-plugin command to check what you need to update.

Hi,

You're right. 
After using check-plugin I've updated the versions as were mentioneded.

Thanks for pointing that out
