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 .

Kubernetes vs. Docker: Understanding the RelationshipMay 12, 2025 am 12:16 AM

The relationship between Docker and Kubernetes is: Docker is used to package applications, and Kubernetes is used to orchestrate and manage containers. 1.Docker simplifies application packaging and distribution through container technology. 2. Kubernetes manages containers to ensure high availability and scalability. They are used in combination to improve application deployment and management efficiency.

Docker: The Container Revolution and Its ImpactMay 10, 2025 am 12:17 AM

Docker solves the problem of consistency in software running in different environments through container technology. Its development history has promoted the evolution of the cloud computing ecosystem from 2013 to the present. Docker uses Linux kernel technology to achieve process isolation and resource limitation, improving the portability of applications. In development and deployment, Docker improves resource utilization and deployment speed, supports DevOps and microservice architectures, but also faces challenges in image management, security and container orchestration.

Docker vs. Virtual Machines: A ComparisonMay 09, 2025 am 12:19 AM

Docker and virtual machines have their own advantages and disadvantages, and the choice should be based on specific needs. 1.Docker is lightweight and fast, suitable for microservices and CI/CD, fast startup and low resource utilization. 2. Virtual machines provide high isolation and multi-operating system support, but they consume a lot of resources and slow startup.

Docker's Architecture: Understanding Containers and ImagesMay 08, 2025 am 12:17 AM

The core concept of Docker architecture is containers and mirrors: 1. Mirrors are the blueprint of containers, including applications and their dependencies. 2. Containers are running instances of images and are created based on images. 3. The mirror consists of multiple read-only layers, and the writable layer is added when the container is running. 4. Implement resource isolation and management through Linux namespace and control groups.

The Power of Docker: Containerization ExplainedMay 07, 2025 am 12:07 AM

Docker simplifies the construction, deployment and operation of applications through containerization technology. 1) Docker is an open source platform that uses container technology to package applications and their dependencies to ensure cross-environment consistency. 2) Mirrors and containers are the core of Docker. The mirror is the executable package of the application and the container is the running instance of the image. 3) Basic usage of Docker is like running an Nginx server, and advanced usage is like using DockerCompose to manage multi-container applications. 4) Common errors include image download failure and container startup failure, and debugging skills include viewing logs and checking ports. 5) Performance optimization and best practices include mirror optimization, resource management and security improvement.

Kubernetes and Docker: Deploying and Managing Containerized AppsMay 06, 2025 am 12:13 AM

The steps to deploy containerized applications using Kubernetes and Docker include: 1. Build a Docker image, define the application image using Dockerfile and push it to DockerHub. 2. Create Deployment and Service in Kubernetes to manage and expose applications. 3. Use HorizontalPodAutoscaler to achieve dynamic scaling. 4. Debug common problems through kubectl command. 5. Optimize performance, define resource limitations and requests, and manage configurations using Helm.

Docker: An Introduction to Containerization TechnologyMay 05, 2025 am 12:11 AM

Docker is an open source platform for developing, packaging and running applications, and through containerization technology, solving the consistency of applications in different environments. 1. Build the image: Define the application environment and dependencies through the Dockerfile and build it using the dockerbuild command. 2. Run the container: Use the dockerrun command to start the container from the mirror. 3. Manage containers: manage container life cycle through dockerps, dockerstop, dockerrm and other commands.

Docker and Linux: Building Portable ApplicationsMay 03, 2025 am 12:17 AM

How to build portable applications with Docker and Linux? First, use Dockerfile to containerize the application, and then manage and deploy the container in a Linux environment. 1) Write a Dockerfile and package the application and its dependencies into a mirror. 2) Build and run containers on Linux using dockerbuild and dockerrun commands. 3) Manage multi-container applications through DockerCompose and define service dependencies. 4) Optimize the image size and resource configuration, enhance security, and improve application performance and portability.
