result:

1. I can't see any log in skywalking-ui
2. when run in local mechaine is ok ( Linux and window ) , just in docker

Your error stack doesn't match your description. I don't know what do you mean. Docker usually only effects network, nothing more.
What you shows in logs, which is some other issues. Maybe you changed the JDK in the image?

[ErciZe]

I've tried copy openjdk of linux to container .
Compare the logs of linux and logs of docker , just can see many Cannot resolve type description for xxx.xxx.....

[wu-sheng]

Your logs make me feeling there are other agents conflicting with SkyWalking. But can't tell more.

[ErciZe]

a while ago i tried copy all of docker to local machine of linux

1. docker cp sky-test2:/skywalking ./
2. docker cp sky-test2:/opt/java ./
3. docker cp sky-test2:/opt/ervice-gateway-2.0.0-SNAPSHOT.jar ./
4. run poject is success , there are no errors in the log

this is error-log skywalking-api.log

[wu-sheng]

Why you install OpenJDK in docker through this strange way. You should build based on official image.
Anyway, this is out of SkyWalking's scope.

[ErciZe]

Throughout，I only use the official image !
I only from official image's enviroment copy to liunx for test
exactly, this is out of SkyWalking's scope. beacuse is successed to run in local machine

[ErciZe]

the problems have been resolve.

focus env : JAVA_TOOL_OPTIONS ='-javaagent:/skywalking/agent/skywalking-agent.jar'
and run project command have javar -javaagent:/skywalking/agent/skywalking-agent.jar

resolve: delete command -javaagent
