在使用Docker过程中,我们会有许多单独使用docker run启动的容器,为了使Compose能够连接这些不在docker-compose.yml中定义的容器,我们需要一个特殊的标签,就是external_links,它可以让Compose项目里面的容器连接到那些项目配置外部的容器(前提是外部容器中必须至少有一个容器是连接到与项目内的服务的同一个网络里面)。 1 ...

我们通过docker部署了nginx,mongo,parse-server和parse-dashboard,但如果每次都需要这么一个个的部署,略微有点麻烦,这时候,我们的docker compose上场了。 Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s servic...
Also, for single-container scenarios, using Docker Compose provides tool-independent configuration in a way that a single Dockerfile does not. Configuration settings such as volume mounts for the container, port mappings, and environment variables can be declared in the docker-compose YML files....
