How to use docker image

Docker images are portable units that package application code and dependencies and can be used to create isolated container environments. To use the image, you need to: Get the image to run the image (a container will be created) manage the container (e.g. start, stop, restart) mount the volume (share data between the container and the host) Set up the port mapping (access the container application from the host)

How to use Docker imagery

Docker is a container platform that allows developers to package and run applications in an isolated environment. Docker images are portable units that package application code, runtime, libraries, and other dependencies.

How to use mirroring?

1. Getting Images: You can get pre-built images from Docker Hub or other image repositories, or you can use the docker build command to build your own image.
2. Run the image: You can use the docker run command to get the image up and run it. This creates and runs the application in the Docker container.
3. Manage containers: You can use the Docker CLI or API to manage running containers. You can start, stop, restart, attach and delete containers.
4. Mount volume: You can mount the host volume into a container using the -v flag. This allows you to share data between container and host.
5. Set port mapping: You can use the -p flag to map container ports to host ports. This allows you to access applications in containers from the host.

Example:

The following example demonstrates how to run a web server using nginx image:

 <code>docker run -d -p 80:80 nginx</code>

This starts the nginx web server in the Docker container and maps container port 80 to host port 80. You can now access the web server by accessing http://localhost on the host.

Notice:

• Make sure Docker is installed and running on your system.
• You need permissions to the image you want to run.
• You can use other flags and options to customize container behavior.
