skywalking java agent 使用，非侵入式
环境
k8s jenkins docker
1.变更程序部署的docker镜像为skywalking java agent镜像
DockerFile
使用image
apache/skywalking-java-agent:8.8.0-java8
这里有个好处
$JAVA_TOOL_OPTIONS 这个是已经有的只要直接使用就好了 -javaagent:/skywalking/agent/skywalking-agent.jar
为了使用grpc进行数据上传，需要进行香瓜皮遏制

2.镜像内插件
/skywalking/agent # ls LICENSE activations config logs optional-reporter-plugins skywalking-agent.jar NOTICE bootstrap-plugins licenses optional-plugins plugins
plugins 文件夹是启用的插件
activations 文件夹是激活的插件
agent在启动的时候会加载两个文件夹中的插件
optional-plugins 可选插件
bootstrap-plugins 插件只有两个 apm-jdk-http-plugin-8.8.0.jar apm-jdk-threading-plugin-8.8.0.jar
这写插件比较恶心，有的互相依赖，不好排除哪些插件，需要去测试。如果插件全部加载，程序启动会比较慢，而且一些切入点没有的话还会报一下错误。对有强迫症的来说，很恶心
3.配置文件中一些可配置项
