Docker指令
- tomcat container 內的工作目錄: /usr/local/tomcat
- 自 image 啟動 container: docker run -p 18080:8080 -v "C:\develop\projects\training-k8s-series\000-container\webapp:/usr/local/tomcat/webapps" tomcat:9.0.75-jdk17
  
  -v "C:\develop\projects\training-k8s-series\000-container\webapp:/usr/local/tomcat/webapps" 此目錄需根據自己的本機目錄改變
- 於 container 內部執行指令並直接印在 console: docker exec <CONTAINER_ID> cat /etc/os-release
- 至 container 內部執行指令操作: docker exec -it <CONTAINER_ID> bash
- 至 container 內部執行指令操作(備選): docker exec -it <CONTAINER_ID> sh
- 包 image: docker build -t "localhost/tomcat-demo:9.0.75-jdk17" .
  
  須注意這必須在 001-image 目錄下執行
- 自 image 啟動 container: docker run -p 18080:8080 localhost/tomcat-demo:9.0.75-jdk17
- 將 image 匯出為 tar檔: docker save -o tomcat-demo_9.0.75-jdk17.tar localhost/tomcat-demo:9.0.75-jdk17
- 將 tar檔匯入為 image: docker load -i tomcat-demo_9.0.75-jdk17.tar
