Docker build没有正确设置环境变量可能导致容器在构建过程中无法获取所需的环境变量值,从而影响应用程序的正常运行。为了解决这个问题,可以采取以下步骤: 确认Dockerfile中是否正确设置了环境变量。在Dockerfile中,可以使用ENV指令来设置环境变量,例如:ENV MY_VAR=my_value确保环境变量的名称和值正确设置。
dockerbuild-tmy_image.dockerrun my_image 1. 2. 输出结果应该是: My environment variable is default_value 1. 接着,我们可以通过-e选项来修改容器中的环境变量: dockerrun-eMY_ENV_VAR=new_value my_image 1. 输出结果应该是: My environment variable is new_value ...

这是围绕从Dockerfile构建Docker映像并运行容器的过程中ARG和ENV可用性的简化概述。它们重叠,但是不能从容器内部使用ARG。 args override in compose file. version: '3' services: somename: build: context: ./app dockerfile: Dockerfile args: some_variable_name: a_value...
Environment variable substitution will use the same value for each variable throughout the entire instruction. In other words, in this example: 在整个指令中,环境变量替换将对每个变量使用相同的值。换句话说,在此示例中: ENVabc=helloENVabc=bye def=$abcENVghi=$abc ...

Environment file Dockerfile Variable is not defined 首先,在 docker-compose.yml 文件中直接设置的值优先级是最高的。 然后是在当前 shell 中 export 的环境变量值。 接下来是在环境变量文件中定义的值。 再接下来是在 Dockerfile 中定义的值。 最后还没有找到相关的环境变量就认为该环境变量没有被定义。
