从前面的部分中我们可以看到,docker compose 提供了足够的灵活性来让我们设置 docker-compose.yml 文件中引用的环境变量,它们的优先级如下: Compose file Shell environment variables 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...
Description of the issue When using docker-compose up or docker-compose run -e ENVIRONMENT_VAR=value, environment variables are not being applied either through the -e command line parameters or from the docker-compose.yml file. The dock...
在使用docker-compose up命令设置两次环境变量时,可以通过编写docker-compose.yml文件来定义容器的配置。以下是一个示例的docker-compose.yml文件: 代码语言:txt 复制 version: '3' services: myapp: image: myapp_image environment: - ENV_VAR1=value1 - ENV_VAR2=value2 ...

Several environment variables are available for you to configure the Docker Compose command-line behaviour. 可以使用几个环境变量来配置Docker Compose命令行行为。 COMPOSE_PROJECT_NAME Sets the project name. This value is prepended along with the service name to the container on start up. For example...
$ docker run --env-file=web-variables.env 1. web-variables.env 文件中可以定义一个或多个环境变量: # define web container env APPNAME=helloworld AUTHOR=Nick Li VERSION=1.0 1. 2. 3. 4. 检查下结果: 原来compose 把 env_file 的设置翻译成了 environment!
docker-compose.yml 文件中引用的环境变量,它们的优先级如下: Compose file Shell environment variables 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。
(docker-compose.yml file:) version: '3' services: example: image: ubuntu environment: - env_var_name=another_value Relevant docs As before, we have another option to writing the variables out. Once again, this will keep the values out of the docker-compose file, as is in good taste....
Docker Compose allows you to specify environment variables directly by using theenvironmentattribute. Below is theYAMLsyntax for this attribute: ... environment: - [key]=[value] - [key2]=[value2] ... For example, to create in-line definitions for the variables listed in the.envfile above...
