How to create a container in Docker?

Step 1: Pull the mirror

Before creating the container, you need to pull the image you want to run. Use the following command:

 <code>docker pull [镜像名]</code>

For example:

 <code>docker pull nginx</code>

Step 2: Create a container

Use the docker run command to create a container:

 <code>docker run [选项] [镜像名] [命令]</code>

Common options:

• -i, --interactive: Keep the container in interactive mode at runtime.
• -t, --tty: Allocate a pseudo-terminal.
• --name: Specify a name for the container.
• -p: Port mapping, map container ports to host ports.

For example, create an interactive Nginx container named "my-nginx" and map container port 80 to host port 8080:

 <code>docker run -it --name my-nginx -p 8080:80 nginx</code>

Step 3: Start the container

After creating the container, you can start it with the docker start command:

 <code>docker start [容器名]</code>

For example:

 <code>docker start my-nginx</code>

Other commands:

• docker attach [Container name]: Attach to the running container.
• docker stop [Container name]: Stop the container.
• docker rm [Container name]: delete the container.
