Minimal container image for running NodeJS apps

The image specifies a default non-root node user (UID 65532), and a working directory at /app, owned by that node user, and accessible to all users.

It specifies NODE_PORT=3000 by default.

Get It!

The image is available on cgr.dev:

docker pull cgr.dev/chainguard/node:latest

Usage Example

Navigate to the example/ directory:

cd example/

The Dockerfile is based on Docker’s Build your Node image tutorial, but uses the Chainguard node base image instead.

Build the application on the node base image.

docker build \
  --tag node-docker \
  --platform=linux/amd64 \
  .

Then you can run the image:

docker run \
  --rm -it \
  -p 8000:8000 \
  --platform=linux/amd64 \
  node-docker

…and test to see that it works:

curl --request POST \
  --url http://localhost:8000/test \
  --header 'content-type: application/json' \
  --data '{"msg": "testing" }'
