How to update easily.

[Passerby1011]

I am a beginner and I am using docker-compose. I would like to ask how to update this project simply. Currently, I am keeping the .env file and deleting the entire project folder, as well as previous docker containers and images, and then recreating them. However, this will cause data loss and is very troublesome.

Hi @Passerby1011,
To update this project without deleting the entire project folder and previous Docker containers and images, you can simply run the following command in your terminal while in the project directory:

version: "3.4"

services:
  # client:
  #   image: nginx-client
  #   build:
  #     context: .
  #     target: nginx-client
  #   restart: always
  #   ports:
  #     - 3080:80
  #   volumes:
  #     - /client/node_modules
  #   depends_on:
  #     - api
  api:
    container_name: chat-clone
    restart: unless-stopped                    # Ensure that the container always restarts unless stopped intentionally
    ports:
      - 3080:3080               # Change it to 9000:3080 to use nginx
    depends_on:
      - mongodb
    image: node-api            # Comment this & uncomment below to build from docker hub image
    build:
      context: .
      target: node-api
    # image: chatgptclone/app:latest # Uncomment this & comment above to build from docker hub image
    env_file:
      - ./api/.env
    environment:
      - HOST=0.0.0.0
      - NODE_ENV=production
      - MONGO_URI=mongodb://mongodb:27017/chatgpt-clone
      # - CHATGPT_REVERSE_PROXY=http://host.docker.internal:8080/api/conversation # if you are hosting your own chatgpt reverse proxy
      - MEILI_HOST=http://meilisearch:7700
      - MEILI_HTTP_ADDR=meilisearch:7700
    volumes:
      - /client/node_modules
      - ./api:/api
      - /api/node_modules
  mongodb:
    container_name: chat-mongodb
    restart: unless-stopped                     # Ensure that the container always restarts unless stopped intentionally
    ports:
      - 27018:27017
    image: mongo
    volumes:
      - ./data-node:/data/db
    command: mongod --noauth
  meilisearch:
    container_name: chat-meilisearch
    restart: unless-stopped                    # Ensure that the container always restarts unless stopped intentionally
    image: getmeili/meilisearch:v1.0
    ports:
      - 7700:7700
    env_file:
      - ./api/.env
    environment:
      - MEILI_HOST=http://meilisearch:7700
      - MEILI_HTTP_ADDR=meilisearch:7700
    volumes:
      - ./meili_data:/meili_data

By doing so, your Docker containers will restart automatically when the Docker daemon starts, and they will not be removed by any Docker commands that stop or restart containers.

I hope this helps! Please let me know if you need help with anything else.

I didn't understand what you meant. You gave me a docker-compose.yml file, but every update has files that are updated, such as these.

，so I will re-git files from Github and rebuild the image。

docker-compose.yml 文件中 mongodb 和 meilisearch 服务应该不会变化。你可以把 mongodb 和 meilisearch 这俩服务单独提取到一个docker-compose.yml文件中，换一个位置，然后执行部署。以后就可以不关注这两个服务了。

1. 更新代码。
2. 构建client (会生成一个dist文件夹)
3. 进入api目录，server/index.js 是入口文件。

我使用的是forever工具，所以直接重启 forever restart [ID] 即可。

@Passerby1011 im not sure if you’ve gotten a good answer but here are the steps that should prevent you from deleting the dir.

Goto your project directory with terminal (you can also open the directory in vs code then open terminal from there), then make sure you are on the right branch with ‘git branch’. Switch to main if not ‘git checkout main’

If you’ve made changes to the files (other than data which won’t affect git), you should use git stash or commit them in another branch. I can explain this more if you’re editing code.

Now use ‘git pull origin main’ and it should pull the latest changes and you shouldn’t have issue if you had no changes to the code files
