Docker can help with CI/CD by providing a consistent environment for every build, deployment, and test. This ensures that each step of the CI/CD process is running in the same environment, which can help to reduce the chances of errors due to environmental differences.
For example, instead of having to configure a new environment for each build, deployment, and test, Docker can be used to create a containerized environment that can be used for each step. This allows the same environment to be used for every step, ensuring that the same results are achieved each time. Additionally, Docker can be used to quickly spin up new environments for testing, which can help to speed up the CI/CD process.
