如何将PM-2 Docker与多阶段Docker Build一起使用

Question

我已经用PM-2 Docker编写了一个多阶段的Dockerfile，但是当我试图用图像运行POD时，Pod Crashes，

Dockerfile

FROM node:16.15.1-alpine3.16 as build

ENV NODE_TLS_REJECT_UNAUTHORIZED=0

# Create app directory
WORKDIR /app

ENV NODE_OPTIONS --max-old-space-size=4096

# Install app dependencies
COPY package.json .

RUN apk update && apk add vim jq busybox-extras

RUN npm install pm2 -g 

RUN npm install --save-exact

COPY . .

FROM node:16.15.1-alpine3.16 as main

COPY --from=build /app /

CMD ["pm2-docker", "index.js"]

错误

node:internal/modules/cjs/loader:936
  throw err;
  ^

Error: Cannot find module '/pm2-docker'
    at Function.Module._resolveFilename (node:internal/modules/cjs/loader:933:15)
    at Function.Module._load (node:internal/modules/cjs/loader:778:27)
    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:77:12)
    at node:internal/main/run_main_module:17:47 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

，编写的多个阶段Dockerfile编写是正确的吗？

我刚刚遇到了这个问题，就像@DR Claw所说的那样，在副本完成了问题之后，在主图像中添加npm install -g pm2。我从构建图像中删除了npm install -g pm2
