This document summarizes things you will find useful when going to production.
Although ORY Hydra implements all Go best practices around running public-facing production http servers, we discourage running ORY Hydra facing the public net directly. We strongly recommend running ORY Hydra behind an API gateway or a load balancer. It is common to terminate TLS on the edge (gateway / load balancer) and use certificates provided by your infrastructure provider (e.g. AWS CA) for last mile security.
You may also choose to set Hydra to HTTPS mode without actually accepting TLS
connections. In that case, all Hydra URLs are prefixed with
https://, but the
server is actually accepting http. This makes sense if you don't want last mile
security using TLS, and trust your network to properly handle internal traffic:
With TLS termination enabled, ORY Hydra discards all requests unless:
- The request is coming from a trusted IP address set by
serve.tls.allow_termination_fromand the header
X-Forwarded-Protois set to
- The request goes to
/health/readywhich does not require TLS termination and that is used to check the health of an instance.
When TLS Termination is enabled, you do not need to provide a TLS Certificate and Private Key.
If you are unable to properly set up TLS Termination, you may want to set the
--dangerous-force-http flag. But please be aware that we discourage you from
doing so and that you should know what you're doing.
It is common to use a router, or API gateway, to route subdomains or paths to a
specific service. For example,
https://myservice.com/hydra/ is routed to
10.0.1.213 is the host running ORY Hydra. To
compute the values for the consent challenge, ORY Hydra uses the host and path
headers from the HTTP request. Therefore, it is important to set up your API
Gateway in such a way, that it passes the public host (in this case
myservice.com) and the path without any prefix (in this case
hydra/). If you
use the Mashape Kong API gateway, you can achieve this by setting
ORY Hydra serves APIs via two ports:
- Public port (default 4444)
- Administrative port (default 4445)
The public port can and should be exposed to public internet traffic. That port handles requests to:
The administrative port should not be exposed to public internet traffic. If you
want to expose certain endpoints, such as the
/clients endpoint for OpenID
Connect Dynamic Client Registry, you can do so but you need to properly secure
these endpoints with an API Gateway or Authorization Proxy. Administrative
None of the administrative endpoints have any built-in access control. You can
curl or Postman requests to talk to them.
The Token Introspection endpoint requires authentication. But since there is no access control, any valid authentication enables the endpoint to be used. If you need to access this endpoint in production, you should configure your API Gateway or Application Proxy to restrict which clients have access to the endpoint.
We generally advise to run ORY Hydra with
hydra serve all which listens on
both ports in one process. Please be aware that the
memory backend will not
work in this mode.
ORY Hydra will bind public and administrative APIs ports to all interfaces.
The interfaces or UNIX sockets used may be specified via environment variables
ADMIN_HOST. Interfaces may be specified as TCP address or as
UNIX socket (giving the absolute path to the socket file prefixed by
ORY Hydra will try to create the socket file during startup and the socket will be writeable by the user running ORY Hydra. The owner, group and mode of the socket can be modified:
