原生kubesphere的B2I镜像不太满足我们实际的业务需求，针对B2I镜像我们做了一些本地化内容

1. 镜像内添加Arthas

镜像内置 Arthas ， 便于调试。

ADD arthas.tar.gz .

当然，这样做不太符合容器设计模式，不应将非业务性内容添加至业务容器内，比较合理的做法就是将这些工具类的内容打包为debug镜像，作为sidecar容器运行。但不得不承认打包在一起管理起来更为方便。

2. 镜像内添加skywalking-agent

为了方便集成链路追踪，我们在基础镜像内置了skywalking-agent

RUN mkdir -p /app/plugins/skywalking
ADD skywalking-agent.tar.gz /app/plugins/skywalking

3.调整jvm参数

jvm参数在原有的基础上添加以下内容

# 时区
-Duser.timezone=GMT+08
# skywalking agent
-javaagent:/app/plugins/skywalking/skywalking-agent/skywalking-agent.jar=agent.service_name=${SW_AGENT_NAME},collector.backend_service=skywalking-oap.${SW_OAP_NAMESPACE:-serviceA}:11800

针对实际需求，我们拓展了B2I基础镜像（比如字体、openoffice等），并在部署阶段调整B2I配置，最终B2I配置如下：
