7. Advanced Dockerfile Directives

In the previous posts of the series, we discussed in depth about Docker images. As we've seen, we've been able to take existing images, provided to the general public in Docker Hub, and run them or reuse them for our purposes. The image itself helps us streamline our processes and reduce the work we need to do.

In the next few posts, we are going to take a more in-depth look at images and how to work with them on our system. We're going to discuss how images can be better organized and tagged, understand how different layers of images work, and set up registries that are both public and private to further reuse the images we have created.

8. Understanding CMD, ENTRYPOINT and RUN in Docker - An Interlude Post

Docker is undeniably a powerful tool for containerization, but its versatility and extensive feature set can be overwhelming, especially for newcomers. The platform offers multiple ways to achieve similar goals, making it crucial for users to carefully weigh the advantages and disadvantages of each option to determine the best approach for their specific projects. This decision-making process requires a solid understanding of Docker's underlying mechanisms and the trade-offs involved in different strategies.

Docker can be a bit of a maze, especially when it comes to the nitty-gritty of instructions like RUN, CMD, and ENTRYPOINT. These three instructions often cause confusion, as they seem to have overlapping functions.

9. Creating Base Docker Images

Creating your base Docker image is quite straightforward. Just as we used the docker commit command previously to create an image from a running container, we can also create an image from a system or server where our applications are originally hosted. However, it's crucial to keep the base image small and lightweight. Simply moving existing applications from traditional servers to Docker isn't enough.

If you're using a production server, the resulting image could end up quite large. For smaller virtual machines that seem ideal for a base image, you can follow these steps to create one. Similar to the docker commit command, this method works for any system you have access to.

11. Docker Image Naming and Tagging

As we get more acquainted with Docker, let's explore a little bit more what image tags are all about, even if we have discussed them before. All told, a tag is essentially a label you apply to your Docker image. Like a little sticky note informing you—and everyone else using the image—something significant about it, including what version it is or what type of software it contains. Consider it as a means of maintaining easily comprehensible and orderly Docker images.

Working on our Docker images, we had assumed that we are all by ourselves. That won't always be the case, though, particularly as our development team expands. The following post will help us to understand how best to tag and name our images for a team environment. Following these guidelines will help us to maintain our Docker images clear and understandable for every project participant..

As a web developer, you might think, "No problem, I'll just use a framework and create a component.". But does it really make sense to bring in an entire library just to re-use some HTML? Shouldn't re-using HTML be something that is supported natively?
