The application I am creating is written in ES6, and other goodies are overloaded with webpack inside the Docker container. At the moment, everything works from creating an internal directory, installing dependencies, and creating a compiled package file.
When the container starts, it says that dist / bundle.js does not exist. Unless I create a package file in the host directory, it will work.
I tried to create a volume for the dist directory in it, it works for the first time, but after making changes and rebuilding it does not pick up new changes.
What I'm trying to achieve is to create a container and run the compiled package. I'm not sure if part of the web package should be in the Docker file as a build step or at runtime, as CMD ["yarn", "start"] , but RUN ["yarn", "start"] works.
Any suggestions and help help. Thanks in advance.
