it is suitable for me. I've done docker pull verticleio/apexbeat . then I start container from that image in interactive shell - docker run -i -t verticleio/apexbeat /bin/sh. Then I see that no any apexbeat executable file on container's filesystem

this is what it looks like on my machine

should look similar on your machine

btw, you were looking for the binary, it's renamed/relocated to /go/bin/app:
FROM golang:alpine

MAINTAINER Jens Saade "jens@verticle.io"

RUN apk update && \
    apk upgrade && \
    apk add git

RUN cd /go/src/
RUN git clone https://github.com/verticle-io/apexbeat.git

RUN mv apexbeat /go/src/app
ADD beatconfig/apexbeat.yml /go/src/app/apexbeat.yml

RUN go get -d -v app
RUN go install -v app

ADD entrypoint.sh /entrypoint.sh
RUN chmod a+x /entrypoint.sh

VOLUME /go/src/app

CMD ["/entrypoint.sh"]
creating that is quite some days ago, but now I remembered ;)
Jens Saade
@jenssaade
you might want to change /go/src/app/apexbeat.yml though, I see it points to "elasticsearch:9200"
used that within a docker-compose scenario I guess
netics-w
@netics-w
Yes, that works. Thanks!
Jens Saade
@jenssaade
perfect ;)

Hi,Jens When the Java -javaagent:apexAgent-v0.7.1-all.jar=myApexAgentConfig.properties is executed, the startup is successful and the error is not reported.
But without executing the Minimal.groovy script, I want to know the reason why I didn't execute Minimal.groovy script, where com.foo.Bar was created, and the console didn't output.

<apex> trying to weave...

<apex> weaving method...

<apex> successfully weaved method...
Foo? Bar!

Jens Saade
@jenssaade
Not sure if I understand correctly. Could you rephrase your problem?

@jenssaade
Ok, so the agent is unable to match that class/method with that signature
Is that class com.foo.Bar on your classpath?
float might also be the problem try to use java.lang.Float instead when matching the signature
Jens Saade

I guess that is what causes your problem.
And I definitely should update the docs: http://toolkits.verticle.io/docs/index.html#configure-instrumentation ;)
still some TODOs in there ...
@heguanglong01 please let me know if your problem is solved.
heguanglong01
@heguanglong01
@jenssaade Thank you. According to your method, the parameter replacement (float-->java.lang.Float) is solved. But a new problem :

heguanglong01
@heguanglong01
@jenssaade Upgrade the apexAgent-0.7-all.jar to the apexAgent-v0.7.1-all.jar problem solution. But apex-service-template accepts information that does not get to the application.com.foo.Bar call.

@jenssaade
@heguanglong01 could you please share your code (e.g. https://gist.github.com/) so I can have a look?
Or create a temporary sample project on github
heguanglong01
@heguanglong01
@jenssaade Thank you very much for the help. The problem has been solved!

@jenssaade
Great! Thats good news 😊
