步骤1:安装Docker 在开始之前,请确保您已经成功安装了Docker。如果您还没有安装Docker,请根据您的操作系统选择相应的安装方法,并按照官方文档进行安装。 步骤2:拉取PostgreSQL镜像 在启动PostgreSQL容器之前,我们需要先从Docker Hub上拉取PostgreSQL的镜像。打开终端或命令行窗口,并执行以下命令:
用户可以通过编写 DockerFile 创建新的镜像,也可以直接从 Docker 的官方仓库 Docker Hub 上下载镜像使用。 容器 Docker 容器是由 Docker 镜像创建的运行实例。Docker 容器类似虚拟机,可以支持的操作包括启动,停止,删除等。每个容器间是相互隔离的,但隔离的效果比不上虚拟机。容器中会运行特定的应用,包含特定应用的代码...
