1. 安装 docker

https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository

2. 安装 dify

请先访问 https://github.com/langgenius/dify 下载 1.0.1 版本的 dify。下载完成之后，解压并在 cmd 中切cd 到 dify-1.0.1/docker 目录下，并执行下面的命令下载并启动 dify docker 镜像。

docker compose up -d

如果执行以上命令出现类似以下报错：

chinacpp@ubuntu:~/dify-1.0.1/docker$ docker compose up -d

使用命令 sudo vim /etc/docker/daemon.json 打开并拷贝如下配置：

{
  "registry-mirrors": [
    "https://docker.1ms.run"
  ]
}

使用下面命令重新启动 docker：

sudo systemctl daemon-reload
sudo systemctl restart docker

停止容器可以执行下面的命令：

docker compose down
