Deploy NodeJS with node-red, mongodb, dashboard in Docker
Docker File
Create this file with the name Dockerfile
and put into your project root folder.
# specify the node base image with your desired version node:<version> FROM node:8 WORKDIR /app RUN chown -R node:node /usr/local/lib/node_modules RUN chown -R node:node /usr/local/bin USER node RUN npm install node-red -g RUN npm install node-red-node-mongodb -g RUN npm i node-red/node-red-dashboard -g # port 1880 for node-red-dashboard EXPOSE 1880 CMD node-red
Important in the Docker File
You need to include the -g
behind, as if you don't the package won't be installed.
RUN npm install node-red -g RUN npm install node-red-node-mongodb -g RUN npm i node-red/node-red-dashboard -g
However, there will be permission error if you just do that. So you need to change the owner and switch the user before that.
RUN chown -R node:node /usr/local/lib/node_modules RUN chown -R node:node /usr/local/bin USER node
The Joy
Then you can build using docker build -t nodejs .
After running the docker image using docker run -it -p 1880:1880 nodejs
You can now access the node-red in your browser.
Btw, you could map multiple ports from the container to host by using multiple -p
option.
