Docker: Uses an image, skipping (docker-compose)

Question

I am currently trying out this tutorial for node express with mongodb https://medium.com/@sunnykay/docker-development-workflow-node-express-mongo-4bb3b1f7eb1e

the first part works fine where to build the docker-compose.yml it works totally fine building it locally so I tried to tag it and push into my dockerhub to learn and try more.

this is originally what's in the yml file followed by the tutorial

version: "2" services:   web:     build: .     volumes:       - ./:/app     ports:       - "3000:3000" 

this works like a charm when I use docker-compose build and docker-compose up

so I tried to push it to my dockerhub and I also tag it as node-test

I then changed the yml file into

version: "2" services:   web:     image: "et4891/node-test"     volumes:       - ./:/app     ports:       - "3000:3000" 

then I removed all images I have previously to make sure this also works...but when I run docker-compose build I see this message error: web uses an image, skipping and nothing happens.

I tried googling the error but nothing much I can find.

Can someone please give me a hand?

Thanks in advance

Answer 1

I found out, I was being stupid.

I didn't need to run docker-compose build I can just directly run docker-compose up since then it'll pull the images down, the build is just to build locally
