Write a Dockerfile: A Dockerfile is used to define the build steps and configuration of a Docker image, make sure it includes all necessary dependencies and configuration information.
Ensure the build process is idempotent: The process of building a Docker image should be idempotent, meaning the resulting image should be the same every time it is built. Make sure there are no random factors or external dependencies in the build process to guarantee the reliability and consistency of the image.
Minimize image size: Try to avoid including unnecessary files and dependencies in the image, you can reduce the image size through methods such as multi-stage building, using base images, and minimizing operations.
Security considerations: When building images, it is important to prioritize security by avoiding including sensitive information or vulnerabilities. Ways to enhance image security include utilizing official images, updating software packages, and adding security patches.
Utilize caching to accelerate the build process: By utilizing Docker’s build cache during the build process, it can speed up the process by avoiding the need to redownload dependencies or reexecute the same steps.
Delete unnecessary files: When building an image, make sure to delete unnecessary and temporary files to reduce the image size and improve clarity.
Tagging and version control: Add appropriate tags and version information to the image for easier management and tracking of different versions of the image.
Testing and validating images: After building an image, it is important to test and validate it to ensure that the image can run correctly and meet the expected functional requirements.
