SIGTERMevents which are signals your application should receive to safely shutdown are instead received by npm or yarn
Here is a Grafana graph showing us Prometheus metrics for an Express Node.JS server. On the left is the
CPU and memory consumption before switching to using
node directly and the right is after.
Each container used around 113MiB before the switch and after around 59MiB of ram.
Run the command your npm or yar
start command runs directly without the package manager.
A Dockerfile might look like this.
FROM node:18-alpine WORKDIR /source ENV NODE_ENV=production PORT=80 CMD node server.js
