Images and containers are closely related in the context of containerization technology.
An image is a lightweight, standalone, executable package that includes everything needed to run a piece of software, including the code, libraries, dependencies, and configurations. It serves as a blueprint for creating containers.
A container, on the other hand, is a runtime instance of an image. It's a isolated and portable environment where the application can run without affecting the host system or other containers.
For example, think of an image as a recipe for a cake, and a container as the actual cake baked following that recipe. Multiple containers can be created from the same image, just like you can bake multiple cakes using the same recipe.
In the cloud computing field, Tencent Cloud provides related services. For instance, its Tencent Container Registry allows you to store and manage container images.
