Deployment Methods

​
Install older version

Use the --branch flag to install a specific version: 
git clone https://github.com/langgenius/dify.git --branch 0.15.3
The rest of the setup is identical to installing the latest version.

​
Install using ZIP archive

For network-restricted environments or when git is unavailable: 
# Download latest release
wget -O dify.zip "$(curl -s https://api.github.com/repos/langgenius/dify/releases/latest | jq -r '.zipball_url')"
unzip dify.zip && rm dify.zip
Alternatively, download the ZIP on another device and transfer it manually. To upgrade: 
wget -O dify-latest.zip "$(curl -s https://api.github.com/repos/langgenius/dify/releases/latest | jq -r '.zipball_url')"
unzip dify-latest.zip && rm dify-latest.zip
rsync -a dify-latest/ dify/
rm -rf dify-latest/
cd dify/docker
docker compose pull
docker compose up -d

​
Backup Procedures

​
Create backup before upgrading

Always backup before upgrading to prevent data loss: 
cp -r dify "dify.bak.$(date +%Y%m%d%H%M%S)"
This creates a timestamped backup for easy restoration.
