Command Line Arguments

Tip

All command line arguments can also be set as environment flags, for example --debug is equivalent to SD_DEBUG=True
All options listed here are available as arguments to use from the command line or as environment variables, there's no need to do both.

CORS in depth

These CORS options are important for controlling which domains are permitted to access the resources of your server. It helps in enhancing the security of your web application by preventing unauthorized cross-origin requests. When configuring these options, ensure that you only allow origins that you trust to interact with your server, as allowing any origin (*) can introduce security vulnerabilities. Always specify the origins explicitly or using a secure regular expression pattern.

• --cors-origins: Allowed CORS origins as a comma-separated list. CORS is a security feature implemented by web browsers that restricts web pages from making requests to a different domain than the one that served the web page. This option allows you to specify a list of origins (domains) that are allowed to access resources on your server. For example, if your application is hosted on http://example.com, and you want to allow access from http://client.example.com, you would set --cors-origins http://client.example.com.
  For local network use, often with other tools, you can just set --cors-origins *.
• --cors-regex: Allowed CORS origins as a regular expression. This option provides more flexibility by allowing you to specify CORS origins using a regular expression. The regular expression should match the origin(s) you want to allow. This is useful when you have a dynamic set of origins that follow a certain pattern. For instance, if you want to allow any subdomain under example.com, you could set --cors-regex "^https?://[a-z0-9-]+\.example\.com$".

TLS in depth

When setting up TLS, it's important to use valid certificates from a trusted CA in a production environment to ensure secure and encrypted communication. In a development or testing environment, self-signed certificates can be used, but users should be cautious when accessing the application as browsers may show security warnings due to the self-signed nature. Always ensure that your TLS setup meets security best practices.

• --tls-keyfile: Enable TLS and specify the key file. TLS is a cryptographic protocol that ensures the secure transmission of data over a network. Enabling TLS in your application secures the communication between the client and the server. The --tls-keyfile option allows you to specify the path to the private key file used for encryption. This private key file should be in PEM format.

Example:

--tls-keyfile /path/to/private-key.pem

• --tls-certfile: Enable TLS and specify the cert file. Along with the private key, you need to specify the TLS certificate file. The certificate file contains the public key and information about the server. It should be in PEM format.

Example:

--tls-certfile /path/to/certificate.pem

• --tls-selfsign: Enable TLS with self-signed certificates. If you don't have a certificate issued by a Certificate Authority (CA), you can enable this option to create self-signed certificates. Self-signed certificates are useful for development and testing but should not be used in production environments where security is crucial.

Example:

--tls-selfsign /path/to/self-signed-certificate.pem
