将清漆添加到现有节点 Dockerfile

Question

我有以下 Dockerfile

FROM node:10-alpine
RUN mkdir -p /home/node/app/node_modules && chown -R node:node /home/node/app
WORKDIR /home/node/app
COPY package*.json ./
USER node
RUN npm install
COPY --chown=node:node . .
EXPOSE 8080
CMD [ "node", "app.js" ]

现在我想添加 Varnish 缓存并考虑这个 repo docker-varnish我如何将两者组织在一起？

一旦我运行这个命令docker compose build它显示了以下信息，但我没有看到任何与清漆相关的东西

我做的对吗？

您可以使用 docker compose 编排多个容器，如下所述：https://www.varnish-software.com/developers/tutorials/running-varnish-docker/#6-docker-compose .

这使用官方 Varnish 图像，而不是您建议的图像。

下面是 docker compose 命令使用的 docker-compose.yml 文件的示例：

version: "3"
services:
  varnish:
    image: varnish:stable
    container_name: varnish
    volumes:
      - "./default.vcl:/etc/varnish/default.vcl"
    ports:
      - "80:80"
    tmpfs:
      - /var/lib/varnish:exec
    environment:
      - VARNISH_SIZE=2G  
    depends_on:
      - "node" 
  node:
    build: ./
    container_name: node
    ports:
      - "8080:8080"

此 docker-compose.yml 文件假定它与您的节点容器的 Dockerfile 位于同一文件夹中。它还假定 default.vcl 也位于该文件夹中。

运行 docker compose up 到 bootstrap 堆栈。
