Don't put all your eggs in one buildpack

Containers are widely recognized as useful programming instruments. However, developers often don’t think about increasing their performance and use out-of-the-box solutions. For example, there are tools that create containers automatically, such as Paketo Buildpacks for Spring Boot apps. But such images either are “black boxes”, sometimes with sub-optimal filling or contain an old Java version or poorly performing scripts. We can avoid skyrocketing costs of cloud resources with the increase of loads and instances if we use performant containers. For that purpose, the developers should take part in deployment optimization, which includes increased speed of container creation, and hence, time to market; Clearly, if we put random eggs into Kubernetes, it won’t improve them but will simply scale sub-optimal entities. If you use K8s, you have to understand - When the problems of underperforming containers may come up; - How to solve them; - What configurable scripts do and how to increase their performance; - How “sitting around and doing nothing” affects the development process. We can optimize containers using built-in instruments. Another approach is to build containers ourselves and only after that get the K8s involved. In my presentation, I will show what to pay attention to in the latter case. Moreover, I will talk about the Native Image technology as all mentioned issues and goals are applicable to it, too.
