What is the purpose of using docker compose build with no cache?

Docker Compose Build with No Cache is an important tool for developers who use Docker Compose to orchestrate the containerized environment of their applications. This command allows developers to ignore the cached version of their images, instead rebuilding them each time they are deployed. This ensures that the user's environment is always up-to-date, reliable and secure.

In a nutshell, Docker Compose is a way of defining a multi-container application or service in a single file. It helps you describe and link the individual containers which make up your application and then use it to orchestrate them as a single unit. Meaning, you can define how your application should run with just one configuration file, saving time and resources in comparison to running all your applications in isolated containers.

By default, when running Docker Compose, it collects all previously built images (stored as cached versions) and deploys them each time an updated version of your app is deployed. However, this means older versions of your application remain stored on your server while they're no longer useful or updated. As such, if any issues arise or any problems occur during deployment due to changes in code - either intentional or accidental - these older versions can cause conflicts and become part of the issue at hand.

Using 'docker-compose build --no-cache' solves this problem by fully rebuilding every image before running them when you deploy an updated version of your application with Docker Compose. Doing this ensures that all sections of your composition are fully up-to-date every single time before being used for deployment - minimizing errors caused by discrepancies between different sections that might have built recently but not at the same having different caches from configurations from before.

In summary, Docker Compose Build with No Cache helps developers:

• Keep their application up-to-date at all times;

• Refresh their stacks each time they deploy applications;

• Prevent any issues resulting from using images that aren't completely updated;

• Save storage space on servers by not keeping multiple cache versions of images produced by Docker Compose;
