Problem "docker-compose -f ./numbers/docker-compose.yml -f ./numbers/prod.yml config > stack.yml" produces an incorrect stack.yml file

Trying to run the command yields: (root) Additional property name is not allowed

Additional context "docker-compose -f ./numbers/docker-compose.yml -f ./numbers/prod.yml config > stack.yml" produces an incorrect stack.yml syntax file

I resolved two initial errors in the file:

  1. unsupported Compose file version: 1.0 ---added version: "3.8" at the beginning of the file
  2. services.numbers-web.ports.0.published must be a integer ---removed quotes around the number 80 (it was flagging published: "80")

I still get the error: (root) Additional property name is not allowed

I suspect this is due to spacing/indentation and how the files were merged. However I cannot put my finger on it. Can someone spot what the error might be?

Much appreciated if anyone can help Thanks!

Original merged stack.yml produced:

Docker-Compose.yml (first file)

Prod.yml (Second File)

Original post spacing got all messed up. Attached are the yml files themselves.

stack.txt docker-compose.txt prod.txt

Solution to this problem was:

Add "version: 3.7" at the beginning Remove the line "name: numbers" Remove the quotation marks around "80" in published port
