Multi-Stage Build Images in CICD

 

Every microservice should be its own separate container. If you only use a single-stage Docker build, you’re probably missing out on some powerful features of the build process. On the other hand, a multi-stage Docker build has many advantages over a single-stage build for deploying microservices.

 Some Advantages are :

- Optimizes the overall size of the Docker image

- Removes the burden of creating multiple Dockerfiles for different stages

- Easy to debug a particular build stage

- Able to use the previous stage as a new stage in the new environment

- Ability to use the cached image to make the overall process quicker

- Reduces the risk of vulnerabilities found as the image size becomes smaller with multi-stage builds
