Docker is the cornerstone of today's development! Let's overview quickly how we use it in JVM development, and then transition to practical examples. We will start with a simple Docker image containing a popular "one fat JAR" and look into its downsides (deployment speed, traffic volume). To address them, we will discuss the strategy of splitting the JAR into multiple layers and using multistage Dockerfiles, gradually improving our image. Join me to learn how to build the ultimate Docker image for Spring applications.
