I can successfully run the following image on a local container.
Dockerfile:
FROM ubuntu:latest
RUN apt-get update
RUN apt-get -qq update
RUN apt-get install -y nodejs npm
# TODO could uninstall some build dependencies
# debian installs `node` as `nodejs`
RUN update-alternatives --install /usr/bin/node node /usr/bin/nodejs 10
COPY package.json package.json
RUN npm install
COPY . .
CMD ["npm", "start"]
The current folder holds a simple "hello world" node-express app, and I can curl it to localhost:3000
.
The depolyment.yml:
apiVersion: apps/v1
kind: Deployment
metadata:
name: node-deployment
labels:
app: node-app
spec:
replicas: 2
selector:

ports:

and the event (kubectl describe pod
):
Warning BackOff 40s (x20 over 5m) kubelet, minikube Back-off restarting failed container
Any suggestions about how to solve the issue?
Well, The pod was created and then crashed over and over again. I discover that by running:
kubctl logs node-deployment-57568f8f75-c2brt
And it was a nodemon problem:
[nodemon] watching: *.*
[nodemon] starting `node app.js`
Example app listening on port 3000!
[nodemon] Internal watch failed: watch /usr/lib/x86_64-linux-gnu/libanl.a ENOSPC
For now I just changed the CMD
in the Dockerfile to:
CMD ["node", "app.js"]
And now the pods are running.
