Issue starting up with Docker

Questions and Answers
1

I’m trying to run Strapi using the method here

The docker logs show:

Error loading the local develop command. Strapi might not be installed in your “node_modules”. You may need to run “npm install”

Is there a better instruction or fix for this issue ?

You can try run
docker-compose up -d && docker strapiexample -f
This should spin up the service and then it will print out what it says. You can also build it again
docker-compose up -d --build to rebuild it which should then run npm install in the container.
Third option is to sh into the container and use npm install like

docker container exec -it strapiexample /bin/bash

bin bash might be bin/sh or bin
