custom authentication

[pkalvagit]

I am new to opentelemenrty. It may be basic question.. I would like to build a custom collector with custom authentication mechanism and also want to include routing and load balancing features along with exports. I have gone through read me of https://github.com/open-telemetry/opentelemetry-collector/tree/main/cmd/builder and https://opentelemetry.io/docs/collector/custom-auth/ . Can someone help to step to build custom authentication and custom collector.

With which step are you having trouble? You should develop your custom authenticator (server authenticator, in your case), and include it in the "extensions" part of your collector manifest.

how to make custom authenticator build part of custom collector in local env? Is there any blog which show step by step approach or if you are able to share also fine..

[jpkrohling]

You can prepare a manifest for the builder with a replace statement pointing to the local directory containing the module. Your build will then include your custom component.

Is it possible to share an example?

tried with replace but without my custom autentication also custom collector getting error: Error: failed to update go.mod: exit status 1.

I am able resolve above loud.google.com/go/compute/metadata: ambiguous import. I added builder-config as below
`extensions:

• import: go.opentelemetry.io/collector/extension/ballastextension
  gomod: go.opentelemetry.io/collector v0.61.0
• import: go.opentelemetry.io/collector/extension/zpagesextension
  gomod: go.opentelemetry.io/collector v0.61.0
• gomod: "github.com/open-telemetry/opentelemetry-collector-contrib/extension/healthcheckextension v0.61.0"
  #- gomod: "github.com/open-telemetry/opentelemetry-collector-contrib/extension/healthcheckextension v0.59.0"

gomod: go.opentelemetry.io/collector v0.61.0

• gomod: "testbasicauthentication"
  path: "/opentelemetry-collector-contrib/extension/testbasicauthentication"`

getting Error: failed to update go.mod: exit status 1. Output: "go: errors parsing go.mod:\nC:\Users\XYZ\opentelemetry-examples\dist\otelcorecol\go.mod:11:2: usage: require module/path v1.2.3\nC:\Users\XYZ\opentelemetry-examples\dist\otelcorecol\go.mod:17:2: require github.com/open-telemetry/opentelemetry-collector-contrib/exporter/testbasicauthentication: version "V0.61.0" invalid: unknown revision V0.61.0\n"

i tried with import inplace gomod but not working. Any suggestions?
