Docker pm2 未在其他镜像中运行

Question

我有 2 个图像节点和 nginx。但我面临的问题是我在节点上全局安装 pm2 但它在其他图像中不起作用，或者我不知道为什么它显示 pm2 未找到，或者我尝试使用 pm2-runtime 但没有任何作用。

FROM node:14.21.3 AS builder

WORKDIR /app

COPY package.json ./

RUN npm i [email protected]
RUN npm install -g @angular/[email protected]
RUN yarn install --ignore-engines
RUN npm install -g pm2

# Copy the entire project directory into the container
COPY . .

# Build both frontend and backend
RUN yarn build-docker

FROM nginx:alpine

# Copy built Angular app from the builder stage to the NGINX HTML directory
COPY --from=builder /app/dist/client /usr/share/nginx/html

# Copy built Node.js backend
COPY --from=builder /app/dist /app/dist

# Expose port 80 for frontend and port 9000 for backend
EXPOSE 80
EXPOSE 9100

# Start both Angular frontend and Node.js backend using PM2
CMD ["pm2", "start", "/app/dist/index.js", "--", "nginx", "-g", "daemon off;"]

Answer 1

您正在构建器阶段安装 pm2 应用程序。

你必须发出命令： 运行 npm install -g pm2

第二阶段（FROM nginx:alpine 线之后）

Answer 2

...

FROM nginx:alpine

# Install Node.js and PM2 in the nginx image
RUN apk add --no-cache nodejs npm
RUN npm install pm2 -g
...

您需要在服务器上安装

pm2

。
