Optimize Spring boot Docker image
A number of techniques are used for maximizing Docker images for Spring Boot apps in order to decrease image size and improve performance. The following are the top three simple procedures:
- Use a lightweight base image: Rather than beginning your Dockerfile with a full-fledged operating system, use an easy base image like Alpine Linux (openjdk:alpine). Your Docker image will be smaller overall since Alpine images are smaller.
- Utilize multi-stage builds: For maintaining the build environment & runtime environment separate use multi-stage builds. This allows you build your Spring Boot application in one step, then copy the created artifact—keeping only the runtime dependencies you need—into a new image in a later step.
- Optimize dependencies: Minimize the number of dependencies in your application by eliminating dependencies which aren’t required in your pom.xml or build.gradle file or by using the –exclude flags option. This improves runtime efficiency and reduces your final Docker image.
How To Optimize Docker Image ?
Docker images are small executable packages that can be used to run a program along with its libraries, dependencies, code, and runtime. Docker images form the basis of Docker containers, which allow software to be deployed continuously across several environments. We will be talking more about Docker image optimization in this blog.
