Prerequisites

Before installing Dify, make sure your machine meets the following minimum system requirements:

  • CPU >= 2 Core
  • RAM >= 4 GiB
Operating SystemSoftwareExplanation
macOS 10.14 or laterDocker DesktopSet the Docker virtual machine (VM) to use a minimum of 2 virtual CPUs (vCPUs) and 8 GB of initial memory. Otherwise, the installation may fail. For more information, please refer to the Docker Desktop installation guide for Mac.
Linux platforms

Docker 19.03 or later

Docker Compose 1.28 or later

Please refer to the Docker installation guide and the Docker Compose installation guide for more information on how to install Docker and Docker Compose, respectively.
Windows with WSL 2 enabledDocker DesktopWe recommend storing the source code and other data that is bound to Linux containers in the Linux file system rather than the Windows file system. For more information, please refer to the Docker Desktop installation guide for using the WSL 2 backend on Windows.

[!IMPORTANT]

Dify 0.6.12 has introduced significant enhancements to Docker Compose deployment, designed to improve your setup and update experience. For more information, read the README.md.

​
Clone Dify

Clone the Dify source code to your local machine:

# Assuming current latest version is 0.15.3
git clone https://github.com/langgenius/dify.git --branch 0.15.3

​
Starting Dify

  1. Navigate to the Docker directory in the Dify source code

    cd dify/docker

  2. Copy the environment configuration file

    cp .env.example .env

  3. Start the Docker containers

    Choose the appropriate command to start the containers based on the Docker Compose version on your system. You can use the $ docker compose version command to check the version, and refer to the Docker documentation for more information:

    • If you have Docker Compose V2, use the following command:
    docker compose up -d
    • If you have Docker Compose V1, use the following command:
    docker-compose up -d

After executing the command, you should see output similar to the following, showing the status and port mappings of all containers:

Finally, check if all containers are running successfully:

docker compose ps

This includes 3 core services: api / worker / web, and 6 dependent components: weaviate / db / redis / nginx / ssrf_proxy / sandbox .

​
Upgrade Dify

Enter the docker directory of the dify source code and execute the following commands:

cd dify/docker
docker compose down
git pull origin main
docker compose pull
docker compose up -d

​
Sync Environment Variable Configuration (Important)

  • If the .env.example file has been updated, be sure to modify your local .env file accordingly.
  • Check and modify the configuration items in the .env file as needed to ensure they match your actual environment. You may need to add any new variables from .env.example to your .env file, and update any values that have changed.

​
Access Dify

# Local environment
http://localhost/install

# Server environment
http://your_server_ip/install

Dify web interface address:

# Local environment
http://localhost

# Server environment
http://your_server_ip

​
