Kubernetes CrashLoopBackOff

Question

创建部署时出错。 这是我在本地运行和测试的 Dockerfile，我也将它推送到 DockerHub

FROM node:14.15.4
WORKDIR /usr/src/app
COPY package*.json ./

RUN npm install
RUN npm install pm2 -g
COPY . .
EXPOSE 3001
CMD [ "pm2-runtime", "server.js" ]

在我的树莓派 3 模型 B 中，我使用 curl -sfL https://get.k3s.io | sh - 安装了 k3s 这是我的控制器-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: controller-deployment
  labels:
    app: controller
spec:
  replicas: 1
  selector:
    matchLabels:
      app: controller
  template:
    metadata:
      labels:
        app: controller
    spec:
      containers:
      - name: controller
        image: akirayorunoe/node-controller-server
        ports:
        - containerPort: 3001

运行此文件后 pod 报错

当我登录 pod 时，它说

standard_init_linux.go:219: exec user process caused: exec format error

这是来自describe pod的回复

您正在尝试在 ARM 机器上启动为 x86（或 x86_64，相同的区别）构建的容器。这不起作用。 ARM 容器必须专门为 ARM 构建并包含 ARM 可执行文件。虽然主要项目正在缓慢地将 ARM 支持添加到其构建中，但您在 Docker Hub 上找到的大多数随机映像或其他任何东西都无法在 ARM 上运行。
