Building Docker image for Node application using Yarn dependency
Solution 1
You should first run yarn install to generate a yarn lockfile (yarn.lock) before building the image. Then make sure to copy it along with the package.json. Your dockerfile should look like this :
FROM node:7
WORKDIR /app
COPY package.json /app
COPY yarn.lock /app
RUN yarn install
COPY . /app
CMD npm run develop
EXPOSE 8000
With this all dependencies should install successfully when building your image
Solution 2
Dockerfile
FROM node:6.9.5-alpine
RUN mkdir -p /code
WORKDIR /code
ADD . /code
RUN npm install -g -s --no-progress yarn && \
yarn && \
yarn run build && \
yarn cache clean
CMD [ "npm", "start" ]
EXPOSE 8080
docker-compose.yml
version: '2'
services:
sample-app:
image: sample-node-yarn-app
ports:
- "8080:8080"
Create docker image
docker build -t sample-node-app .
RUN
docker-compose up -d
Solution 3
You can simplify the above answers by using a predefined yarn docker image. We are assuming here this image is only for development purpose. For production mode, you should only consider the minimum binaries, such as node.
FROM gmolaire/yarn:1.22.4_12.18.3-alpine3.12
WORKDIR /usr/local/app
ADD . .
RUN yarn install && \
yarn build
EXPOSE 8080
CMD [ "yarn", "run", "develop" ]

I am trying to build a docker image for a node application that uses yarn to install dependencies. My Dockerfile looks like this:
FROM node:7 WORKDIR /app COPY package.json /app RUN yarn install COPY . /app CMD npm run develop EXPOSE 8000
Every thing runs well when I run yarn install on my local machine but when I do a docker build, I get this error that blocks for ever.
**docker build -t rs .** Sending build context to Docker daemon 219.1MB Step 1/7 : FROM node:7 ---> d9aed20b68a4 Step 2/7 : WORKDIR /reason ---> Using cache ---> fe51a1860989 Step 3/7 : COPY package.json /reason ---> Using cache ---> b0e136ee6eeb Step 4/7 : RUN yarn install ---> Running in e273f8cf1f3e yarn install v0.24.4 info No lockfile found.

The console remains in this stage for ever. How can I fix this please.

JBone over 6 yearsthis looks more like issue with the packages that you are using. Try installing without docker. Just do a regular install on your machine (npm install) and see what happens. look for that particular module (and the version number) on npmjs.org.

Jinna Balu over 6 yearshow areyou running your application without docker, npm run develop? if so change your CMD line like this "CMD ["npm", "run", "develop"] "

Kendo Nguimi over 6 yearsThanks for the help. Now the image builds successfully but I'm unable to run it. When I do a docker run, it shows my site is running at localhost:8000 but when I go to the browser, nothing is seen. It says Safari can't connect to server mean while when I do a normal run with npm run develop everything works fine and I can see my site. What can be the problem here?

Clive Makamara over 6 yearsYou need to make sure of two things. 1) That you are exposing 8000 with for example docker run -p 8000:8000 myimage 2) The dev server is running on 0.0.0.0 instead of localhost instead of localhost just to make sure it will work as expected

Jinna Balu over 6 yearsto reduce the image size use alpine, you need to clean yar. check my answer
-
Clive Makamara over 6 yearsWhy do you need docker compose for a single image?
-
Jinna Balu over 6 yearsi don't think this will be a big mess, to easy our joob, run command is reduced to "docker-compose up" and "docker-compose down"
