Docker containeris nothing but an environment virtualized during run-time to allow users to isolate applications from the system underpinning it. These containers are compact紧凑的,简洁的, portable轻便的 units in which you can start up an application quickly and easily. A notable feature is the ad...
When a Docker user runs an image, it becomes one or multiple container instances. The container’s initial state can be whatever the developer wants — it might have an installed and configured web server, or nothing but a bash shell running as root. In practice, though, most images include...
docker stop [container] 停止給定的容器。 docker wait [container] 使給定的容器等待,直到其他正在執行的容器停止。 映像命令 與容器命令相比,映像命令較少。 Docker build -t image_name . 從當前目錄中的檔案建置標記為 image_name 的Docker 映像。 docker create [image] 從給定的映像建置非執行的容器。

镜像的一个实例称为容器。 你有一个镜像,这是你描述的一组图层。 如果你开始这个镜像,你有一个运行这个镜像的容器。 您可以拥有许多相同镜像的正在运行的容器。 docker images 查看所有镜像 docker ps 查看正在运行的容器 docker ps -a 查看所有容器
It defines the desired state of the application, such as the number of replicas, the Docker image to use, and the desired ports to expose. Tasks: Tasks are the individual units of work that Docker Swarm assigns to nodes. A task is a combination of a Docker container and the command to...
其实很容易区分二者,image即镜像,类似操作系统的iso文件,而container则是用这iso文件安装好的一个操作系统。 参考 [1]Use the Docker command line, Docker Documentation [2]what's the difference between docker stop and docker kill?, superuse, Steffen Opel ...

制作镜像有两种通用的方法,第一种是直接通过配置好的Container来生成镜像;另外一种是通过Dockerfile的方式,基于已有的镜像来生成新的镜像,这种方法更为常用。 配置Container制作镜像 这里以制作nginx的镜像为例,介绍整个制作流程。 1)下载基础镜像,这里以Ubuntu作为基础镜像。由于本地没有镜像可以先利用docker search获取...
Use Docker Compose:Docker Compose allows you to define and manage multi-container applications, ensuring proper synchronization and volume sharing. Here’s an example of a Docker Compose file that defines a service with a named volume: version:'3.8'services:app:image:myappvolumes:-myvolume:/app/...
