I extend my context because I need some file outside of Dockerfile directory.

This is my command : docker build -f Dockerfile ../../ docker run (imageID)

file structure:

• model
• servers
  • subscribeship (I run docker command in this directory)
    • Dockerfile
    • index.js
    • package.json
    • package-lock.json

in my Dockerfile:

FROM node:10

WORKDIR /app

COPY ./servers/subscribeship/package*.json .

RUN npm install

COPY ./servers/subscribeship .

COPY ./models ../../models

EXPOSE 3000

CMD ["node","index.js"]

It seems like npm install not working. package.json & package-lock.json indeed have sequelize package

I use same method for test if is my way wrong but it seems work..

I create another directory call bug, as same as servers level. and then create bug1 directory inside bug folder like this:

command:

docker build -f Dockerfile ../../
docker run (imageId)

• bug
  • bug1 (run command in here)
    • Dockerfile
    • package.json
    • pakcage-lock.json
    • .dockerignore

dockerfile:

FROM node:10

WORKDIR /app

COPY ./bug/bug1/package.json .

RUN npm install

COPY ./bug/bug1 .

EXPOSE 3000

CMD ["node","index.js"]

./ means you are navigating from the current directory. If you are running a command in /servers/subscribeship, ./ will refer to this directory. ./servers/subscribeship/package*.json will then refer to /servers/subscribeship/servers/subscribeship/package*.json. Because this directory does not exist package.json is not copied and npm install will not install the required modules.

I solved my problem. It turn out that model directory doesn't have package.json.
