There are ways of using Docker where you have absolutely no dependencies on the environment that you work in. This allows us to deploy Docker anywhere anytime and this has been most valuable.
The most valuable feature of Docker is that it revolutionized virtualization by providing a new approach with containers that completely nullified the time it used to take to deploy applications on virtual servers, resulting in deployment times that can be as quick as milliseconds, unless it is a heavy application, such as Java. Additionally, resource utilization has greatly improved with Docker, allowing for more resources to be allocated to other tasks. These are a few key features that make Docker a preferred choice.

The tool helps us in code versioning. I think it's pretty much easy to use and very straightforward. Even if someone is new to the tool, they can easily start using it with a little guidance or theoretical knowledge. Go through the tool and start using it without much struggle.

If you install Docker on a host, it creates its own firewalls. It can become an issue. Usually, when you want to install Docker, you need to restart the firewall or restart the active tables on the machine, but this is not the case with Kubernetes. It uses the default set up by the next administrator, but with Docker, you have to restart the firewall and restart Docker before the firewall on the system will be okay. If you do not the rules will not be created.

There are elements of stability that are problematic. One of the most recent upgrades created a major incident on our cloud, whereby the containers were not restarting automatically.
There may not be much room for improvement with Docker as it has greatly evolved. However, one area that could be improved upon is the documentation on their website which was once easy to follow but has become quite terrible with numerous versions being released. As an example, the installation process for Docker now requires more than just a one-line command, causing inconvenience. Additionally, based on my experience as a college instructor, teaching students to install Docker was a difficult task due to the lack of straightforward and easy-to-follow documentation. Docker should focus on improving their documentation to make it more user-friendly for all.

Sometimes, we have sync-up issues where the build doesn't get processed due to these sync issues, causing the build to fail. That's one of the drawbacks I see. When we did a huge sync-up, we faced a couple of issues. It takes some time for us to complete the sync-up. For frequent, smaller updates, we haven't had any issues. However, challenges can arise for those who prefer doing everything in one go. This might not necessarily be due to the tool itself but because of the approach of doing everything in a single batch.
