Hello, I’m a bit new here and signed up just because of this issue I’m having and busting my head because of it…
I am totally new to docker and docker compose (ofc), started a few days ago with docker in general.
So the issue I’m having is as follows;
I have one root folder for a project which includes the app and server.
docker-compose.yml \_ server \_ dockerfile \_ package.json \_ index.js \_ ... \_ app \_ dist \_ ... \_ dockerfile \_ package.json \_ index.js \_ ...
The docker-compose.yml includes the following
version: "3.4" services: app: container_name: projectmanagerApp restart: always build: context: ./app dockerfile: ./app/dockerfile dns: - 22.214.171.124 - 126.96.36.199 ports: - "80:8000" depends_on: - server healthcheck: test: ["CMD", "curl", "-f", "http://localhost:8000"] interval: 1m30s timeout: 10s retries: 3 start_period: 30s networks: - projectmanagerNET server: container_name: projectmanagerServer restart: always image: node:10 build: ./server dns: - 188.8.131.52 - 184.108.40.206 ports: - "81:8001" expose: - 8001 # links: # - mongo # depends_on: # - mongo healthcheck: test: ["CMD", "curl", "-f", "http://localhost:8001"] interval: 1m30s timeout: 10s retries: 3 start_period: 30s networks: - projectmanagerNET # mongo: # container_name: projectmanagerMongo # image: mongo # dns: # - 220.127.116.11 # - 18.104.22.168 # expose: # - "27017" # healthcheck: # test: ["CMD", "echo", "'db.runCommand(\"ping\").ok'", "|", "mongo", "localhost:27017/test", "--quiet"] # interval: 1m30s # timeout: 10s # retries: 3 # start_period: 30s # networks: # - projectmanagerNET networks: projectmanagerNET:
### Initialisation #Define the base image - using node v.10, official docker image FROM node:10 #Define the maintainer of this image LABEL maintainer="email@example.com" #Define the working directory (on final container) WORKDIR /var/app #Set the default registry for NPM RUN npm config set registry http://registry.npmjs.org/ ### Build process # Copy the package.json, package-lock.json from host machine to build container COPY package*.json ./ # Install all dependencies on the build container RUN npm install --quiet ### Post build process #Copy all the files from the build container to final container COPY . . #Start the server in the container CMD [ "npm", "run", "serve" ]
Both subapps (app, server) can be build using
docker build --rm --tag testingImage . and run using
docker run --name testContainer testingImage and both startup without any errors at all.
But when using docker-compose I get the following errors:
Starting projectmanagerServer ... done Starting projectmanagerApp ... done Attaching to projectmanagerServer, projectmanagerApp projectmanagerApp | projectmanagerApp | > firstname.lastname@example.org serve /var/app projectmanagerApp | > node server.js projectmanagerApp | projectmanagerApp | internal/modules/cjs/loader.js:584 projectmanagerApp | throw err; projectmanagerApp | ^ projectmanagerApp | projectmanagerApp | Error: Cannot find module '/var/app/server.js' projectmanagerApp | at Function.Module._resolveFilename (internal/modules/cjs/loader.js:582:15) projectmanagerApp | at Function.Module._load (internal/modules/cjs/loader.js:508:25) projectmanagerApp | at Function.Module.runMain (internal/modules/cjs/loader.js:754:12) projectmanagerApp | at startup (internal/bootstrap/node.js:283:19) projectmanagerApp | at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3) projectmanagerApp | npm ERR! code ELIFECYCLE projectmanagerApp | npm ERR! errno 1 projectmanagerApp | npm ERR! email@example.com serve: `node server.js` projectmanagerApp | npm ERR!

Short version: cmd
node server.js is executed for no reason at all, even though I have specified in the dockerfile the
CMD [ "npm", "run", "serve" ]
Thank you for any support or suggestions what I might have done wrong in advance.
