I am currently using Harbor as a Docker image configuration management tool in my company. Before running the Next.js Docker image on the Linux server, I push the Docker image to Harbor and then execute it on the server.
However, I am facing a problem where both the size of the node_modules file in the Next.js Docker image and the overall size of the Docker image are large. As a result, it takes a long time to push the image to Harbor, averaging more than 8 minutes.
To reduce the image size, I have tried reducing the running steps and optimizing the project using techniques like using a builder, running 'npm install --production', and removing the '.next/cache' directory. However, these efforts have not significantly resolved the issue.
The team keeps insisting on reducing the image size due to the lengthy build time. However, based on my current knowledge, I believe that this level of optimization is the best I can achieve.
If anyone has encountered a similar problem, I would appreciate any hints or workarounds they can provide.
Thank you.

I want to speed up image builds and reduce time to push to harbor.
These are 5 steps you need to perform:
https://snyk.io/blog/choosing-the-best-node-js-docker-image/)You should definetly try Dive(https://github.com/wagoodman/dive),which serves for exploring a docker image, layer contents, and discovering ways to shrink the size of your Docker/OCI image.
After checking these steps it does not matter if your are using Harbor or any other image repository.
