How 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
Copy after login

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
Copy after login

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
Copy after login

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.
