When I try to build a Nodejs application with a Docker file I have received “npm ERR! Tracker “idealTree” already exists” error. I noticed the error with Node version 15.
Here is my Dockerfile.
#Base image name
FROM node:alpine
COPY ./ ./
RUN npm install
#default command
CMD [“npm”,”start”]
And when executing the docker build command I got the below error.
azureuser@Devops-test-vm:~/simpleweb$ docker build . Sending build context to Docker daemon 4.096kB Step 1/4 : FROM node:alpine ---> 48de5d16038c Step 2/4 : COPY ./ ./ ---> aead9d57f1a5 Step 3/4 : RUN npm install ---> Running in 4638cdcc19d5 npm notice npm notice New minor version of npm available! 7.15.1 -> 7.16.0 npm notice Changelog: <https://github.com/npm/cli/releases/tag/v7.16.0> npm notice Run `npm install -g npm@7.16.0` to update! npm notice npm ERR!

To fix the error I have added a working directory in the docker file as below.
#Base image name
FROM node:alpine
WORKDIR /usr/app
COPY ./ ./
RUN npm install
#default command
CMD [“npm”,”start”]
And this time the build was successful.
