HELP: Can you explain this a little more ?

https://github.com/BretFisher/node-docker-good-defaults/blob/master/bin/www#L22

After getting through the docker-compose section of your class, I figured I’d try to get my local env running before continuing to docker swarm.

I used this repo as kind of a guide. My set up isn’t complicated services = [nest.js, redis, postgres] (nest.js is a framework around express)

I’m also using yarn and nodemon installed locally. CMD ['yarn', 'start:dev'] #=> nodemon

nodemon.json
{
  "watch": ["src"],
  "ext": "ts",
  "ignore": ["src/**/*.spec.ts", "src/graphql.schema.ts"],
  "exec": "ts-node -r tsconfig-paths/register src/main.ts"
}

docker-compose up works just find, but when I save a file it fails …

Any ideas?

Great! Interesting, yea I keep using the default and not alpine because little issues like this keep creeping up and the default images keep getting smaller so it’s not as big a deal to force alpine on anyone, hence this repo’s still not using alpine by default.

OK just pushed a commit to update nodemon. Nice catch.
