When discussing the upgrading of software to newer versions, one of the main issues for developers, maintainers, and ensuring correct software functionality after the upgrade arises. Now, if this upgrade includes the popular programming language PHP and the powerful Laravel framework, domain relevance becomes essential. Well, let's take a look at the best methods for performing this task, particularly when all these operations are carried out in Docker containers.
The first step is to prepare a complete version of the current project. This task ensures that if any issues arise during the upgrade, you can easily revert back to the previous state. By using Docker, you can easily retrieve the data and the current versions of the project earlier.
After preparing the previous version, you must update your Dockerfile to use the latest PHP version. This includes changing the base image (base image) to one that runs PHP in the container. By switching to a newer image, you can take advantage of the features and enhancements this newer PHP version offers.
Another crucial step in this process is to perform comprehensive testing after updating Docker and PHP. This includes running all unit tests and integration tests to ensure everything works as expected or even better.
Additionally, if you want the application to run in production environments, it's better to utilize tools such as CI/CD for automating the deployment process. These tools can help minimize risks by continuously pushing the new changes to real environments.
