the steps of Go Docker multi-stage builds

7 min read

  1. Choose a base image: The first step is to choose a base image that will be used for the build. The base image should have all the necessary tools and libraries required for the build process.

  2. Create a builder image: The next step is to create a builder image that will be used to build the Go application. This image is created using the base image selected in the previous step.

  3. Build the Go application: In this step, the Go application is built inside the builder image. The source code is copied to the builder image and the application is compiled.

  4. Create a final image: Once the Go application is built, a final image is created using the base image selected in the first step. This final image will include only the compiled Go application and any necessary runtime dependencies.

  5. Copy the application from builder to final image: In this step, the Go application that was built in the builder image is copied to the final image.

  6. Run the application: In the final step, the Go application is run inside the final image. This image can then be pushed to a Docker registry and deployed to a production environment.
