下面是一个简单的状态图,展示了Dockerfile中设置环境变量的过程: Set_Environment_VariableBuild_ImageRun_Container 在这个状态图中,我们首先设置环境变量,然后构建镜像,最后运行容器。整个过程形成了一个循环,不断地构建和运行容器,以满足不同的需求。
以下是一个简化的类图,用于展示Docker容器与环境变量之间的关系。 DockerContainer+create()+start()+stop()+setEnv(variable: String)+getEnv(variable: String)EnvironmentVariable+key: String+value: String 在该类图中,DockerContainer表示一个Docker容器,容器通过setEnv和getEnv方法来设置和获取环境变量。 总结 在Do...
