Proxy Service Configuration

Introduction

The proxy service is an API-Gateway for the ownCloud Infinite Scale microservices. Every HTTP request goes through this service. Authentication, logging and other preprocessing of requests also happens here. Mechanisms like request rate limiting or intrusion prevention are not included in the proxy service and must be set up in front like with an external reverse proxy.

Default Values

  • The proxy listens on port 9200 by default.

Authentication

The following request authentication schemes are implemented:

  • Basic Auth (Only use in development, never in production setups!)

  • OpenID Connect

  • Signed URL

  • Public Share Token

Automatic Quota Assignments

It is possible to automatically assign a specific quota to new users depending on their role. To do this, you need to configure a mapping between roles defined by their ID and the quota in bytes. The assignment can only be done via a yaml configuration and not via environment variables. See the following proxy.yaml config snippet for a configuration example.

role_quotas:
    <role ID1>: <quota1>
    <role ID2>: <quota2>

Automatic Role Assignments

When users log in, they automatically get a role assigned. The automatic role assignment can be configured in different ways. The PROXY_ROLE_ASSIGNMENT_DRIVER environment variable (or the driver setting in the role_assignment section of the configuration file) selects which mechanism to use for the automatic role assignment.

  • When PROXY_ROLE_ASSIGNMENT_DRIVER is set to default, all users that do not have a role assigned at the time of their first login will get the role 'user' assigned. (This is also the default behavior if PROXY_ROLE_ASSIGNMENT_DRIVER is unset.

  • When PROXY_ROLE_ASSIGNMENT_DRIVER is set to oidc, the role assignment for a user will happen based on the values of an OpenID Connect Claim of that user. The name of the OpenID Connect Claim to be used for the role assignment can be configured via the PROXY_ROLE_ASSIGNMENT_OIDC_CLAIM environment variable. It is also possible to define a mapping of claim values to role names defined in ownCloud Infinite Scale via a yaml configuration. See the following proxy.yaml snippet for an example.

    role_assignment:
    driver: oidc
    oidc_role_mapper:
        role_claim: ocisRoles
        role_mapping:
            - role_name: admin
              claim_value: myAdminRole
            - role_name: spaceadmin
              claim_value: mySpaceAdminRole
            - role_name: user
              claim_value: myUserRole
            - role_name: guest
              claim_value: myGuestRole

    This would assign the role admin to users with the value myAdminRole in the claim ocisRoles. The role user to users with the values myUserRole in the claim ocisRoles and so on.

    Claim values that are not mapped to a specific Infinite Scale role will be ignored.

    An Infinite Scale user can only have a single role assigned. If the configured role_mapping and a user’s claim values result in multiple possible roles for a user, the order in which the role mappings are defined in the configuration is important. The first role in the role_mappings where the claim_value matches a value from the user’s roles claim will be assigned to the user. So if e.g. a user’s ocisRoles claim has the values myUserRole and mySpaceAdminRole that user will get the ocis role spaceadmin assigned (because spaceadmin appears before user in the above sample configuration).

    If a user’s claim values don’t match any of the configured role mappings, an error will be logged and the user will not be able to log in.

    The default role_claim (or PROXY_ROLE_ASSIGNMENT_OIDC_CLAIM) is roles. The default role_mapping is:

    - role_name: admin
  claim_value: ocisAdmin
- role_name: spaceadmin
  claim_value: ocisSpaceAdmin
- role_name: user
  claim_value: ocisUser
- role_name: guest
  claim_value: ocisGuest

Recommendations for Production Deployments

  • The proxy service is the only service communicating to the outside and therefore needs the usual protection against DDOS, Slow Loris or other attack vectors. All other services are not exposed to the outside, but also need protective measures when it comes to distributed setups like when using container orchestration over various physical servers.

  • In a production deployment, you want to have basic authentication (PROXY_ENABLE_BASIC_AUTH) disabled which is the default state. You should also set up a firewall to only allow requests to the proxy service or the reverse proxy if you have one. Requests to the other services should be blocked by the firewall.

Caching

The proxy service can use a configured store via PROXY_OIDC_USERINFO_CACHE_STORE. Possible stores are:

Store Type Description

memory

Basic in-memory store and the default.

ocmem

Advanced in-memory store allowing max size.

redis

Stores data in a configured Redis cluster.

redis-sentinel

Stores data in a configured Redis Sentinel cluster.

etcd

Stores data in a configured etcd cluster.

nats-js

Stores data using the key-value-store feature of NATS JetStream.

noop

Stores nothing. Useful for testing. Not recommended in production environments.

  1. Note that in-memory stores are by nature not reboot-persistent.

  2. Though usually not necessary, a database name and a database table can be configured for event stores if the event store supports this. Generally not applicable for stores of type in-memory. These settings are blank by default which means that the standard settings of the configured store apply.

  3. The proxy service can be scaled if not using in-memory stores and the stores are configured identically over all instances.

  4. When using redis-sentinel, the Redis master to use is configured via PROXY_OIDC_USERINFO_CACHE_NODES in the form of <sentinel-host>:<sentinel-port>/<redis-master> like 10.10.0.200:26379/mymaster.

Special Settings

When using the Infinite Scale IDP service instead of an external IDP:

  • Use the environment variable OCIS_URL to define how Infinite Scale can be accessed; mandatory is the use of https as protocol for the URL.

  • If no reverse proxy is set up, the PROXY_TLS environment variable must be set to true because the embedded libreConnect shipped with the IDP service has a hard check if the connection is on TLS and uses the HTTPS protocol. If this mismatches, an error will be logged and no connection from the client can be established.

  • PROXY_TLS can be set to false if a reverse proxy is used and the https connection is terminated at the reverse proxy. When setting to false, the communication between the reverse proxy and Infinite Scale is not secured. If set to true, you must provide certificates.

Configuration

A comma separated list of nodes to access the configured store. This has no effect when 'memory' or 'ocmem' stores are configured. Note that the behaviour how nodes are used is dependent on the library of the configured store.

OCIS_CACHE_DATABASE

string

ocis

The database name the configured store should use.

PROXY_OIDC_USERINFO_CACHE_TABLE

string

userinfo

The database table the store should use.

OCIS_CACHE_TTL
PROXY_OIDC_USERINFO_CACHE_TTL

Duration

10s

Default time to live for user info in the user info cache. Only applied when access tokens has no expiration. The duration can be set as number followed by a unit identifier like s, m or h. Defaults to '10s' (10 seconds).

OCIS_CACHE_SIZE
PROXY_OIDC_USERINFO_CACHE_SIZE

int

0

The maximum quantity of items in the user info cache. Only applies when store type 'ocmem' is configured. Defaults to 512.

PROXY_OIDC_JWKS_REFRESH_INTERVAL

uint64

60

The interval for refreshing the JWKS (JSON Web Key Set) in minutes in the background via a new HTTP request to the IDP.

PROXY_OIDC_JWKS_REFRESH_TIMEOUT

uint64

10

The timeout in seconds for an outgoing JWKS request.

PROXY_OIDC_JWKS_REFRESH_RATE_LIMIT

uint64

60

Limits the rate in seconds at which refresh requests are performed for unknown keys. This is used to prevent malicious clients from imposing high network load on the IDP via ocis.

PROXY_OIDC_JWKS_REFRESH_UNKNOWN_KID

bool

true

If set to 'true', the JWKS refresh request will occur every time an unknown KEY ID (KID) is seen. Always set a 'refresh_limit' when enabling this.

PROXY_OIDC_REWRITE_WELLKNOWN

bool

false

Enables rewriting the /.well-known/openid-configuration to the configured OIDC issuer. Needed by the Desktop Client, Android Client and iOS Client to discover the OIDC provider.

OCIS_JWT_SECRET
PROXY_JWT_SECRET

string

The secret to mint and validate JWT tokens.

PROXY_ROLE_ASSIGNMENT_DRIVER

string

default

The mechanism that should be used to assign roles to user upon login. Supported values: 'default' or 'oidc'. 'default' will assign the role 'user' to users which don’t have a role assigned at the time they login. 'oidc' will assign the role based on the value of a claim (configured via PROXY_ROLE_ASSIGNMENT_OIDC_CLAIM) from the users OIDC claims.

PROXY_ROLE_ASSIGNMENT_OIDC_CLAIM

string

roles

The OIDC claim used to create the users role assignment.

PROXY_ENABLE_PRESIGNEDURLS

bool

true

Allow OCS to get a signing key to sign requests.

PROXY_ACCOUNT_BACKEND_TYPE

string

cs3

Account backend the PROXY service should use. Currently only 'cs3' is possible here.

PROXY_USER_OIDC_CLAIM

string

preferred_username

The name of an OpenID Connect claim that is used for resolving users with the account backend. The value of the claim must hold a per user unique, stable and non re-assignable identifier. The availability of claims depends on your Identity Provider. There are common claims available for most Identity providers like 'email' or 'preferred_username' but you can also add your own claim.

PROXY_USER_CS3_CLAIM

string

username

The name of a CS3 user attribute (claim) that should be mapped to the 'user_oidc_claim'. Supported values are 'username', 'mail' and 'userid'.

OCIS_MACHINE_AUTH_API_KEY
PROXY_MACHINE_AUTH_API_KEY

string

Machine auth API key used to validate internal requests necessary to access resources from other services.

PROXY_AUTOPROVISION_ACCOUNTS

bool

false

Set this to 'true' to automatically provision users that do not yet exist in the users service on-demand upon first sign-in. To use this a write-enabled libregraph user backend needs to be setup an running.

PROXY_ENABLE_BASIC_AUTH

bool

false

Set this to true to enable 'basic authentication' (username/password).

PROXY_INSECURE_BACKENDS

bool

false

Disable TLS certificate validation for all HTTP backend connections.

PROXY_HTTPS_CACERT

string

Path/File for the root CA certificate used to validate the server’s TLS certificate for https enabled backend services.

PROXY_POLICIES_QUERY

string

Defines the 'Complete Rules' variable defined in the rego rule set this step uses for its evaluation. Rules default to deny if the variable was not found.
