How can I optimize my Node.js Docker image?
To optimize your Node.js Docker image, you can start by using a smaller base image like 'node:alpine'. This reduces the overall size.
What are some other techniques I can use?
You can also minimize the number of layers by combining commands in your Dockerfile, and use multi-stage builds to keep only the necessary files.
Should I include development dependencies in the image?
No, it's best to exclude development dependencies in production images. Use the --production
flag when installing packages.
How can I check the size of my Docker image?
You can check the size of your Docker image by running docker images
in your terminal, which lists all images and their sizes.
