open-liberty - 内核超薄 UBI docker 镜像不适用于 springBootUtility

Question

团队，是否可以将 springBootUtility 与 OpenLiberty kernel-slim UBI 图像(例如 - kernel-slim-java8-openj9-ubi)一起使用？
https://openliberty.io/docs/21.0.0.7/reference/command/springbootUtility-thin.html
因为，它给出了一个错误

Step 3/11 : RUN springBootUtility thin --sourceAppPath=/staging/fat-order-0.0.1-SNAPSHOT.jar --targetThinAppPath=/staging/thin-order-0.0.1-SNAPSHOT.jar --targetLibCachePath=/staging/lib.index.cache---> Running in 3023c669c4d7/bin/sh: springBootUtility: command not found

springBootUtility 仅适用于 OpenLiberty 完整 UBI 图像

Answer 1

kernel-slim image 似乎根本没有该命令。比较 kernel-slim :

bash-5.1$ docker run --rm -it openliberty/open-liberty:kernel-slim-java8-openj9-ubi ls /opt/ol/wlp/bin
auditUtility      binaryLog.bat       productInfo      securityUtility.bat  serverSchemaGen
auditUtility.bat  featureUtility      productInfo.bat  server           serverSchemaGen.bat
binaryLog     featureUtility.bat  securityUtility  server.bat       tools

致 full :

bash-5.1$ docker run --rm -it openliberty/open-liberty:full-java8-openj9-ubi ls /opt/ol/wlp/bin
auditUtility      binaryLog.bat  featureUtility      pluginUtility  securityUtility.bat  springBootUtility
auditUtility.bat  client     featureUtility.bat  pluginUtility.bat  server           springBootUtility.bat
batchManager      client.bat     jaxb            productInfo    server.bat       tools
batchManager.bat  ddlGen     jaxrs           productInfo.bat    serverSchemaGen
binaryLog     ddlGen.bat     jaxws           securityUtility    serverSchemaGen.bat

文档中似乎有一个漏洞，因为没有任何迹象表明您需要这样做，但是您需要安装 springBoot在添加命令之前将功能导入 Open Liberty。将指定 spring boot 的 server.xml 复制到镜像中，然后运行 ​​ features.sh :

COPY --chown=1001:0 server.xml /config/
RUN features.sh

之后， springBootUtility将被放置在 /opt/ol/wlp/bin dir 并且应该在路径上，以便进一步使用 Dockerfile 指令。
