Exiting: error unpacking config data: more than one namespace configured accessing 'output' (source:'apm-server.yml')

[wajika]

There is already an output.elasticsearch configuration in the original docker image, what should I do to close it?

If I set output.elasticsearch.enable: false, how can I output the template of apm-server to elasticsearch?

There are a lot of errors on apm ui, I don’t know what’s going on

Is that "apm-server:7.7.1" image an alias for docker.elastic.co/apm/apm-server:7.7.1? Or have you built your own image? The Docker images we build are configured via the apm-server.yml file, and since you're overriding the file I don't understand how you would end up with that error message.

Anyway, there are typos in your config; you should use "enabled" and not "enable". See Configure the Elasticsearch output | APM User Guide [8.11] | Elastic

There are a lot of errors on apm ui, I don’t know what’s going on

I don't know either. I'd suggest opening a separate topic for that, and provide the Kibana logs.

Thank you for your reply, I am using docker.elastic.co/apm/apm-server:7.7.1
Sorry, my no certification check character is wrong. I will modify and test again.
I have a question, is apm ui generated by apmserver template?
