How to view mirror information by docker
How to view Docker image information: List all images: docker images View specific image information: docker inspect [mirror ID or name] View image file system: docker run -it [mirror ID or name] /bin/sh
How to view Docker image information
Docker images are lightweight, executable software packages that contain all the files and code needed to run an application. To view Docker image information, you can use the following steps:
1. List all images
<code class="bash">docker images</code>
This lists information for all locally stored Docker images, including:
- REPOSITORY : Mirror name
- TAG : Mirror tags
- IMAGE ID : A unique identifier for the image
- SIZE : The size of the mirror
2. View specific mirror information
To view the details of a specific image, use the docker inspect command followed by the image's ID or name:
<code class="bash">docker inspect [镜像ID或名称]</code>
This outputs a JSON format file with the following information about the mirror:
- Architecture : Mirrored architecture (such as amd64 or arm64)
- Author : Mirror Author
- Config : Mirror configuration
- ContainerConfig : Container Configuration
- Created : mirror creation date and time
- History : Mirror build history
- Labels : Labels associated with mirrors
- Manifest : Mirror manifest
- Os : The operating system used for mirroring
- RootFS : Mirrored root file system
- Size : The size of the mirror
3. View the mirror file system
To view the contents of the mirrored file system, use the docker run command and pass the -it option to the command so that you can go to the image and view its contents:
<code class="bash">docker run -it [镜像ID或名称] /bin/sh</code>
This will start an interactive container where you can view the contents of the mirrored file system using commands such as ls .
