Docker is a very powerful system if it is used correctly. While the team behind Docker is continuously improving the system for developers to completely focus on the open source coding, as a user you can also take initiative to improve your user experience. Here are some of the tips.

 

Doing A Security Check

As one of the best containerization technology, Docker is on the more secure end. However, no open source platforms are 100 percent secure. Therefore, checking on docker image security is highly recommendable. When it comes to using images in Docker, it is highly important to use image scanning. While it can only defend images against some security vulnerabilities, it is one step toward a better security strategy.

 

Use A VPS

A Virtual Private Server, VPS for short, is a service that stores data for you. A VPS somewhat works like a remote computer, as you can do almost anything from web hosting to hosting a gaming server. Some users will use it for running a high-traffic website. But within the framework of Docker, a VPS can be used to run the platform at a higher speed. Not all users have a great internet connection, but by using a VPS, you can work at a quicker tempo.

 

Help From The Community

The purpose of open source projects is also the collaboration between users. Many Docker users will experience gaining more knowledge when participating in discussion boards about Docker. If you have any questions regarding images, there is always an experienced Docker user, who is able to answer the question.

And there is still a spot for you if you are already in the know. Therefore, participating in the discussion could be a way for you to help other newcomers. A good place to look is IRC, where there is a channel specifically for Docker questions.

 

Optimize Docker Images

When using Docker containers for images, you might experience wanting to optimize your images. There are several reasons for that: Larger images cost more, they are slower and take up more space. When trying to enable smaller sizes, some of the tips include choosing multi-stage builds and using a better base image. When choosing an image, it should have a small OS footprint.

Therefore, you need to choose a relatively small base image. There are base images at the small size of 5.59 megabytes, which also is a safer size to use. The reason why images can take up much space is because of their many layers. Therefore, using multi-stage builds is a way to eliminate that problem. Multi-stage essentially means that you can split up the process into separate images. You will experience that the image size will be much reduced.

 

Upgrading The Latest Version

When working with images in Docker, there can often be a lot, and it can be difficult to keep track of them. But because the images in the containers don’t update by themselves, you will have to update them yourselves. Updating images is important, as you can make them more secure. But an update will also make applications more smooth. The process of updating the images is essentially stopping and removing the current container and replacing it with the newest version of the image.

 

Conclusion

Because Docker is a very powerful tool, it would be a shame not to take advantage of the small adjustments in order to get the most optimal version. Docker will mostly work on improving the speed, but in the meantime, you can do so by choosing a VPS as mentioned in the article. Perhaps you will discover other tips on your own that will make the Docker experience even more enjoyable.
