Question

必须承认我不是docker专家，但是尽管开始在命令行上登录docker还是有问题：

awk -F':' 'NF{sub(/^ +/,"",$2);a[$1]=(a[$1]?a[$1] ORS $2:$2)} END{for(i in a){print i ORS a[i]}}' Input_file

这是项目中的yaml文件：

awk -F':' '                        ##Setting field separator as colon here.
NF{                                ##Checking if NF value is NOT NULL where NF is number of fields in current line.
  sub(/^ +/,"",$2)                 ##Using sub function of awk which substitutes all initial/starting space from $2(second field) with NULL.
  a[$1]=(a[$1]?a[$1] ORS $2:$2)    ##Creating an array named a whose index is first field of current line and concatenating $2 values to its previous value.
}                                  ##Closing block for NF condition here.
END{                               ##Starting END condition of awk command here.
  for(i in a){                     ##Starting a for loop to traverse through array a here.
    print i ORS a[i]               ##Printing index of array a which is variable i now and ORS(new line) and then value of array a whose index is variable i.
  }                                ##Closing block for for loop here.
}'  Input_file                     ##Mentioning Input_file name here.

这是docker文件：

AdminsMacBook-2:dockertest newadmin$ sudo docker-compose -f src/main/docker/app.yml up
Password:

您需要先构建应用程序的Docker映像，然后才能启动它。 dockertest2在您的本地Docker映像中不存在。

要创建应用程序的Docker映像并将其推送到Docker注册表中：

使用Maven，输入：./mvnw package -Pprod verify jib:dockerBuild

使用Gradle，输入：./gradlew -Pprod bootWar jibDockerBuild

这将使用prod配置文件打包您的应用程序，并使用Jib连接到本地Docker守护程序来构建Docker映像。
