原生kubesphere的B2I鏡像不太滿足我們實(shí)際的業(yè)務(wù)需求，針對(duì)B2I鏡像我們做了一些本地化內(nèi)容

1. 鏡像內(nèi)添加Arthas

鏡像內(nèi)置 Arthas ， 便于調(diào)試。

ADD arthas.tar.gz .

當(dāng)然，這樣做不太符合容器設(shè)計(jì)模式，不應(yīng)將非業(yè)務(wù)性內(nèi)容添加至業(yè)務(wù)容器內(nèi)，比較合理的做法就是將這些工具類的內(nèi)容打包為debug鏡像，作為sidecar容器運(yùn)行。但不得不承認(rèn)打包在一起管理起來更為方便。

2. 鏡像內(nèi)添加skywalking-agent

為了方便集成鏈路追蹤，我們?cè)诨A(chǔ)鏡像內(nèi)置了skywalking-agent

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

3.調(diào)整jvm參數(shù)

jvm參數(shù)在原有的基礎(chǔ)上添加以下內(nèi)容

# 時(shí)區(qū)
-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

針對(duì)實(shí)際需求，我們拓展了B2I基礎(chǔ)鏡像（比如字體、openoffice等），并在部署階段調(diào)整B2I配置，最終B2I配置如下：
