This change causes the duplicated images error here. Is it necessary?

[louie-tsai]

this is the original flow, and I just change the path where GenAIcomps is located. it seems that multiple examples like agentqna, audioqna and workflowagent build the agent image. don't quite understand why multiple builds cause issues. any suggestion?

[letonghan]

It's the CI check to make sure unified docker image path.
@chensuyue Could you help to check this, is it possible to skip this?

[chensuyue]

This issue means all the image named opea/agent should build from the same dockerfile. And the scripts think ${WORKDIR:-./}/GenAIComps/comps/agent/src/Dockerfile in this build yaml is different with GenAIComps/comps/agent/src/Dockerfile used by other build yaml.
Is this change force required? If not, you can just recover the change here to avoid the issue.

[louie-tsai]

recovered it and changed README instructions instead. after recovery, we will have GenAIComp github repo under GenAIExamples. it looks confusing, but it should work
