我可以在本地容器上成功运行以下图像。
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"]
当前文件夹包含一个简单的" hello world" node-express app,我可以将它卷曲到localhost:3000
。
depolyment.yml:
apiVersion: apps/v1
kind: Deployment
metadata:
name: node-deployment
labels:
app: node-app
spec:
replicas: 2
selector:
matchLabels:

containers:

ports:

和事件(kubectl describe pod
):
Warning BackOff 40s (x20 over 5m) kubelet, minikube Back-off restarting failed container
有关如何解决问题的任何建议?
答案 0 :(得分:0)
嗯,创建了pod,然后一遍又一遍地崩溃。我发现通过运行:
kubctl logs node-deployment-57568f8f75-c2brt
这是一个nodemon问题:
[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
现在我刚刚将Dockerfile中的CMD
更改为:
CMD ["node", "app.js"]
现在豆荚正在运行。
