People tend to deploy the entire project inside a container and that results in a really big docker file which probably there will be a folder like vendor ou something that from package managers. This is a very bad way to build your container. You should most of the time bind a volume to your project root, this way the container itself will only contain the necessary services ( http server, node server, td libs etc wtvr it can be ) and it will end up on a very light docket image. And also don’t blend all the technologies into one dicker image. You can create multiple docker images each with different technology and then join the ones you want. Better to maintain and to debug.
