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...

如果docker-compose up 指定启动tomcat1,nginx也会启动。因为配置文件中定义了依赖关系,对于存在依赖关系的应用默认启动。 6、设置环境变量:environment 其与env_file标签完全不同,反而与arg有几分类似,作用就是设置环境变量。它可以保存变量到镜像里面,也就是说启动的容器也会包含这些变量设置——这也是其与arg最大的...

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。
Specify the path to a custom environment file that defines the Docker Compose environment variables. This is similar to using the --env-file option with the docker compose command. By default, the Docker Compose run configuration looks for a file named .env in the directory with the Docker Co...
