首先打开dify所在目录，进入到docker文件夹下，如没有.env文件，请将.env.example文件复制并改名为.env
（这里我的路径是：D:\dify-0.15.3\docker）

知识库上传文件大小及数量限制

# ------------------------------
# Knowledge Configuration
# ------------------------------

# Upload file size limit, default 15M.
UPLOAD_FILE_SIZE_LIMIT=15

# The maximum number of files that can be uploaded at a time, default 5.
UPLOAD_FILE_BATCH_LIMIT=5

大模型生成结果最大token限制

# ------------------------------
# Model Configuration
# ------------------------------

# The maximum number of tokens allowed for prompt generation.
# This setting controls the upper limit of tokens that can be used by the LLM 
# when generating a prompt in the prompt generation tool.
# Default: 512 tokens.
PROMPT_GENERATION_MAX_TOKENS=512

# The maximum number of tokens allowed for code generation.
# This setting controls the upper limit of tokens that can be used by the LLM 
# when generating code in the code generation tool.
# Default: 1024 tokens.
CODE_GENERATION_MAX_TOKENS=1024

工作流http请求节点响应大小限制

# HTTP request node in workflow configuration
HTTP_REQUEST_NODE_MAX_BINARY_SIZE=4194304
HTTP_REQUEST_NODE_MAX_TEXT_SIZE=1048576

工作流http请求节点访问其他主机上的服务

# Environment Variables for sandbox Service

# The API key for the sandbox service
SANDBOX_API_KEY=dify-sandbox
# The mode in which the Gin framework runs
SANDBOX_GIN_MODE=release
# The timeout for the worker in seconds
SANDBOX_WORKER_TIMEOUT=15
# Enable network for the sandbox service
SANDBOX_ENABLE_NETWORK=true
# HTTP proxy URL for SSRF protection
SANDBOX_HTTP_PROXY=http://ssrf_proxy:3128
# HTTPS proxy URL for SSRF protection
SANDBOX_HTTPS_PROXY=http://ssrf_proxy:3128
# The port on which the sandbox service runs
SANDBOX_PORT=8194

同时，还需要修改docker-compose.yaml文件

networks:
  # create a network between sandbox, api and ssrf_proxy, and can not access outside.
  ssrf_proxy_network:
    driver: bridge
    internal: true
  milvus:
    driver: bridge
  opensearch-net:
    driver: bridge
    # internal: true

将internal: true注释掉

工作流http请求节点请求超时限制

  sandbox:
    image: langgenius/dify-sandbox:0.2.10
    restart: always
    environment:
      # The DifySandbox configurations
      # Make sure you are changing this key for your deployment with a strong key.
      # You can generate a strong key using `openssl rand -base64 42`.
      API_KEY: ${SANDBOX_API_KEY:-dify-sandbox}
      GIN_MODE: ${SANDBOX_GIN_MODE:-release}
      WORKER_TIMEOUT: ${SANDBOX_WORKER_TIMEOUT:+15}
      ENABLE_NETWORK: ${SANDBOX_ENABLE_NETWORK:-true}
      HTTP_PROXY: ${SANDBOX_HTTP_PROXY:-http://ssrf_proxy:3128}
      HTTPS_PROXY: ${SANDBOX_HTTPS_PROXY:-http://ssrf_proxy:3128}
      SANDBOX_PORT: ${SANDBOX_PORT:-8194}
    volumes:
      - ./volumes/sandbox/dependencies:/dependencies
    healthcheck:
      test: [ 'CMD', 'curl', '-f', 'http://localhost:8194/health' ]
    networks:
      - ssrf_proxy_network

设置WORKER_TIMEOUT(我这里简单粗暴的+15，操作有待商榷)

通过.env，docker-compose.yaml，docker-compose.middleware.yaml这三个配置文件，可以解决绝大多数因为配置问题而导致的工作节点报错情况，文件当中还有其他很多配置参数，目前只总结了自己所遇到的一些情况，方便下次回顾
