HomeOperation and MaintenanceDockerHow to install software libraries in docker images (step analysis)

Docker is currently the most popular lightweight containerization technology, which allows developers to easily and quickly build, deploy and run applications. As developers, we often need to install some applications or software libraries in Docker containers to support our development work. So, how to install the software library in the Docker image? Below, we will detail the steps to install the software library in the Docker image.

Step 1: Choose the appropriate image
First, choose the appropriate image according to your needs. An image is equivalent to a software package. In Docker, all applications and software run based on the image. If you need to install Python or Node.js software libraries, then you need to choose an image that includes these locales. There are many open source images on Docker Hub for you to choose from. You can find the image you need through the search function of Docker Hub. For example, if you want to install a Python software library, you can choose the official python image.

Step 2: Run the container
After you select the appropriate image, you need to run a container. A Docker container is a running instance of an image. You can execute your application in a Docker container for testing and development. You can use the following command to run a container:

docker run -it IMAGE_NAME /bin/bash

Among them, IMAGE_NAME is the image name you selected, and /bin/bash is the command to enter the container. This command will start a new container and enter the container's terminal.

Step 3: Install the software library
After entering the container's terminal, you can use regular Linux commands to install the software library. For example, if you want to install Python's requests library, you can use the following command:

pip install requests

During the installation process, Docker will download the required library files from the network and install them into the container.

Step 4: Save the image
After the installation is completed, you can exit the container and save the container status for easy use next time. You can use the following command to save the container status:

docker commit CONTAINER_ID NEW_IMAGE_NAME

Among them, CONTAINER_ID is the container ID, which can be obtained by running the docker ps -a command, and NEW_IMAGE_NAME is the new image name. This command will create a new image and save the state of your installed software libraries and other containers. Later, you can reuse the container and keep the repository installed by running this new image.

In summary, if you want to install a software library in a Docker image, you need to select the appropriate image, run the container, install the software library, and save the image. Using Docker allows us to develop and test more conveniently, while also ensuring the consistency and reproducibility of the environment, improving development efficiency and code quality.

Docker vs. Kubernetes: Use Cases and ScenariosDocker vs. Kubernetes: Use Cases and ScenariosApr 23, 2025 am 12:11 AM

Select Docker in a small project or development environment, and Kubernetes in a large project or production environment. 1.Docker is suitable for rapid iteration and testing, 2. Kubernetes provides powerful container orchestration capabilities, suitable for managing and expanding large applications.

Docker on Linux: Containerization for Linux SystemsDocker on Linux: Containerization for Linux SystemsApr 22, 2025 am 12:03 AM

Docker is important on Linux because Linux is its native platform that provides rich tools and community support. 1. Install Docker: Use sudoapt-getupdate and sudoapt-getinstalldocker-cedocker-ce-clicotainerd.io. 2. Create and manage containers: Use dockerrun commands, such as dockerrun-d--namemynginx-p80:80nginx. 3. Write Dockerfile: Optimize the image size and use multi-stage construction. 4. Optimization and debugging: Use dockerlogs and dockerex

Docker is a containerization tool, and Kubernetes is a container orchestration tool. 1. Docker packages applications and their dependencies into containers that can run in any Docker-enabled environment. 2. Kubernetes manages these containers, implementing automated deployment, scaling and management, and making applications run efficiently.

Docker's Purpose: Simplifying Application DeploymentDocker's Purpose: Simplifying Application DeploymentApr 20, 2025 am 12:09 AM

The purpose of Docker is to simplify application deployment and ensure that applications run consistently in different environments through containerization technology. 1) Docker solves the environmental differences problem by packaging applications and dependencies into containers. 2) Create images using Dockerfile to ensure that the application runs consistently anywhere. 3) Docker's working principle is based on images and containers, and uses the namespace and control groups of the Linux kernel to achieve isolation and resource management. 4) The basic usage includes pulling and running images from DockerHub, and the advanced usage involves managing multi-container applications using DockerCompose. 5) Common errors such as image building failure and container failure to start, you can debug through logs and network configuration. 6) Performance optimization construction

Docker simplifies application deployment and management on Linux. 1) Docker is a containerized platform that packages applications and their dependencies into lightweight and portable containers. 2) On Linux, Docker uses cgroups and namespaces to implement container isolation and resource management. 3) Basic usages include pulling images and running containers. Advanced usages such as DockerCompose can define multi-container applications. 4) Debug commonly used dockerlogs and dockerexec commands. 5) Performance optimization can reduce the image size through multi-stage construction, and keeping the Dockerfile simple is the best practice.
