# Docker Compose 部署
|
||
|
||
### 前提条件
|
||
|
||
| Operating System | Software | Description |
|
||
| -------------------------- | -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
|
||
| macOS 10.14 or later | Docker Desktop | Set the Docker Virtual Machine (VM) to use at least 2 virtual CPUs (vCPU) and 8 GB of initial memory. Otherwise, the installation may fail. For more information, see [Install Docker Desktop on Mac](https://docs.docker.com/desktop/mac/install/). |
|
||
| Linux platforms | <p>Docker 19.03 or later<br>Docker Compose 1.25.1 or later</p> | 请参阅[安装 Docker](https://docs.docker.com/engine/install/) 和[安装 Docker Compose](https://docs.docker.com/compose/install/) 以获取更多信息。 |
|
||
| Windows with WSL 2 enabled | <p>Docker Desktop<br></p> | 我们建议将源代码和其他数据绑定到 Linux 容器中时，将其存储在 Linux 文件系统中，而不是 Windows 文件系统中。有关更多信息，请参阅[使用 WSL 2 后端在 Windows 上安装 Docker Desktop](https://docs.docker.com/desktop/windows/install/#wsl-2-backend)。 |
|
||
|
||
### Clone Dify
|
||
|
||
Clone Dify 源代码至本地
|
||
|
||
```bash
|
||
git clone https://github.com/langgenius/dify.git
|
||
```
|
||
|
||
### Start Dify
|
||
|
||
进入 dify 源代码的 docker 目录，执行一键启动命令：
|
||
|
||
```Shell
|
||
cd dify/docker
|
||
cp .env.example .env
|
||
docker compose up -d
|
||
```
|
||
|
||
> 如果您的系统安装了 Docker Compose V2 而不是 V1，请使用 `docker compose` 而不是 `docker-compose`。通过`$ docker compose version`检查这是否为情况。在[这里](https://docs.docker.com/compose/#compose-v2-and-the-new-docker-compose-command)阅读更多信息。
|
||
|
||
部署结果：
|
||
|
||
```Shell
|
||
[+] Running 7/7
|
||
✔ Container docker-web-1 Started 1.0s
|
||
✔ Container docker-redis-1 Started 1.1s
|
||
✔ Container docker-weaviate-1 Started 0.9s
|
||
✔ Container docker-db-1 Started 0.0s
|
||
✔ Container docker-worker-1 Started 0.7s
|
||
✔ Container docker-api-1 Started 0.8s
|
||
✔ Container docker-nginx-1 Started
|
||
```
|
||
|
||
最后检查是否所有容器都正常运行：
|
||
|
||
```bash
|
||
docker compose ps
|
||
```
|
||
|
||
包括 3 个业务服务 `api / worker / web`，以及 4 个基础组件 `weaviate / db / redis / nginx`。
|
||
|
||
```bash
|
||

|
||
```
|
||
|
||
### 更新 Dify
|
||
|
||
进入 dify 源代码的 docker 目录，按顺序执行以下命令：
|
||
|
||
```bash
|
||
cd dify/docker
|
||
git pull origin main
|
||
docker compose down
|
||
docker compose pull
|
||
docker compose up -d
|
||
```
|
||
|
||
#### 同步环境变量配置 (重要！)
|
||
|
||
* 如果 `.env.example` 文件有更新，请务必同步修改您本地的 `.env` 文件。
|
||
|
||
* 检查 `.env` 文件中的所有配置项，确保它们与您的实际运行环境相匹配。您可能需要将 `.env.example` 中的新变量添加到 `.env` 文件中，并更新已更改的任何值。
|
||
|
||
### 访问 Dify
|
||
|
||
|
||
在浏览器中输入 `http://localhost` 访问 Dify。
|
||
|
||
### 自定义配置
|
||
|
||
编辑 `.env` 文件中的环境变量值。然后，重新启动 Dify：
|
||
|
||
```bash
|
||
docker compose down
|
||
docker compose up -d
|
||
```
|
||
|
||
完整的环境变量集合可以在 `docker/.env.example` 中找到。
