ARG是Dockerfile中唯一可能出现在FROM之前的指令,见ARG与FROM的相互影响 FROM可以在单个Docker文件中多次出现以创建多个图像,或者使用一个构建阶段作为另一个的依赖。 在每个新的FROM指令之前,简单地记录通过提交输出的最后一个图像ID。每个FROM指令清除由先前指令创建的任何状态。 FROM可以在一个Dockerfile中出现多次来创...
An ARG declared before a FROM is outside of a build stage, so it can’t be used in any instruction after a FROM. To use the default value of an ARG declared before the first FROM use an ARG instruction without a value inside of a build stage: 在FROM之前声明的ARG在构建阶段之外,所以...
2.Dockerfile必须以FROM指令开始(除ARG指令之外),否则会出现"Please provide a source image withfromprior to commit"。 CMD echo "Before FROM" FROM nginx CMD /bin/bash 1. 2. 3. 3.FROM可以在一个Dockerfile中出现多次,以创建多个镜像或者将当前构建作为另一个构建的依赖。 4.通...
ARG是唯一可以在 Dockerfile 中的 FROM 之前的指令。请参阅了解ARG和FROM之间的交互方式。 FROMcan appear multiple times within a singleDockerfileto create multiple images or use one build stage as a dependency for another. Simply make a note of the last image ID output by the commit before each...

ARG is the only instruction that may precede FROM in the Dockerfile. FROM can appear multiple times within a single Dockerfile to create multiple images or use one build stage as a dependency for another. Simply make a note of the last image ID output by the commit before each new FROM ...
Docker 按顺序运行指令Dockerfile。必须以指令Dockerfile开头FROM。这可能在解析器指令、注释和全局范围 的ARG之后。该FROM指令指定您正在构建的父图像。FROM前面只能有一个或多个ARG指令,这些指令声明FROM在Dockerfile. Docker 将开头的行#视为注释,除非该行是有效的解析器指令。行中任何其他位置的#标记都被视为参数...
