# 假设当前最新版本为 0.15.3
git clone https://github.com/langgenius/dify.git --branch 0.15.3

docker-compose up -d

  • 排查下来docker-compose.yaml中的weaviate没有启动,以及服务器docker-compose版本

    $docker-compose version
    Docker Compose version v2.2.2

  • 解决办法指定profile

    1
    docker-compose --profile weaviate up -d

配置域名开启HTTPS

  • 主要是修改配置文件(.env)

  • 先修改NGINX_PORT和NGINX_SSL_PORT防止默认端口与其他端口冲突

    # ------------------------------
    # Environment Variables for Nginx reverse proxy
    # ------------------------------
    # HTTP port
    NGINX_PORT=10086
    # SSL settings are only applied when HTTPS_ENABLED is true
    NGINX_SSL_PORT=10087

    # ------------------------------
    # Docker Compose Service Expose Host Port Configurations
    # ------------------------------
    EXPOSE_NGINX_PORT=10086
    EXPOSE_NGINX_SSL_PORT=10087

  • 然后使用docker-compose -f docker-compose.yaml up -d先将服务启动起来

  • 成功启动后,继续修改配置文件(.env)

    # if HTTPS_ENABLED is true, you're required to add your own SSL certificates/keys to the `./nginx/ssl` directory
    # and modify the env vars below accordingly.
    NGINX_SSL_CERT_FILENAME=fullchain.pem
    NGINX_SSL_CERT_KEY_FILENAME=privkey.pem

    # Set true to accept requests for /.well-known/acme-challenge/
    NGINX_ENABLE_CERTBOT_CHALLENGE=true

    # Certbot Configuration

    # Email address (required to get certificates from Let's Encrypt)
    CERTBOT_EMAIL=your_email@example.com

    # Domain name
    CERTBOT_DOMAIN=your_domain.com

  • 然后使用docker-compose --profile certbot up --force-recreate -d启动certbot服务

  • 然后使用docker exec -it cerbot /bin/sh /update-cret.sh 来申请证书

  • 修改配置文件(.env)

    # 开启NGINX HTTPS
    NGINX_HTTPS_ENABLED=true

  • 然后使用``docker-compose --profile certbot up --force-recreate -d --no-deps nginx重建一下nginx`服务
