# The config file version. Currently this field is optional but future
# KES versions will require it. The only valid value is "v1".
version: v1
# The TCP address (ip:port) for the KES server to listen on.
address: 0.0.0.0:7373 # The pseudo address 0.0.0.0 refers to all network interfaces
admin:
# The admin identity identifies the public/private key pair
# that can perform any API operation.
# The admin account can be disabled by setting a value that
# cannot match any public key - e.g. "foobar" or "disabled".
identity: c84cc9b91ae2399b043da7eca616048d4b4200edf2ff418d8af3835911db945d
# The TLS configuration for the KES server. A KES server
# accepts HTTP only over TLS (HTTPS). Therefore, a TLS
# private key and public certificate must be specified,
# either here as part of the config file or via CLI arguments.
tls:
key: ./server.key # Path to the TLS private key
cert: ./server.cert # Path to the TLS certificate
password: "" # An optional password to decrypt the TLS private key
# An optional path to a file or directory containing X.509 certificate(s).
# If set, the certificate(s) get added to the list of CA certificates for
# verifying the mTLS certificates sent by the KES clients.
#
# If empty, the system root CAs will be used.
ca: ""
# The TLS proxy configuration. A TLS proxy, like nginx, sits in
# between a KES client and the KES server and usually acts as a
# load balancer or common endpoint.
# All connections from the KES client to the TLS proxy as well
# the connections from the TLS proxy to the KES server must be
# established over TLS.
proxy:
# The identities of all TLS proxies directly connected to the
# KES server.
#
# Note that a TLS proxy can act as any identity (including root)
# since it can forward arbitrary client certificates. Client certificates
# aren't secret information and a malicious TLS proxy can fake any
# identity it has seen before. Therefore, its critical that all TLS proxy
# identities are secure and trusted servers.
identities: []
# The HTTP header sent by the TLS proxy to forward certain data
# about the client to the KES server.
header:
# The HTTP header containing the URL-escaped and PEM-encoded
# certificate of the kes client forwarded by the TLS proxy.
cert: X-Tls-Client-Cert
# The API configuration. The APIs exposed by the KES server can
# be adjusted here. Each API is identified by its API path.
#
# In general, the KES server uses sane defaults for all APIs.
# Only customize the APIs if there is a real need.
#
# Disabling authentication for an API must be carefully evaluated.
# One example, when authentication may be justified monitoring via
# the /v1/metrics API. It is possible that providing identities
# to auto-scaling monitoring instances may not be feasable in certain
# environments. However, in general it is better to use API keys or
# TLS client certificates if possible.
#
# When authentication is disabled, the particular API can be
# accessed by any client that can send HTTPS requests to the
# KES server.
# Currently, authentication can only be disabled for the
# following APIs:
# - /v1/status
# - /v1/metrics
# - /v1/api
#
api:
/v1/metrics:
skip_auth: false
timeout: 15s
/v1/status:
skip_auth: false
timeout: 15s
# The (pre-defined) policy definitions.
#
# A policy must have an unique name (e.g my-app) and specifies which
# server APIs can be accessed. An API path pattern is a glob pattern
# of the following form:
# <API-version>/<API>/<operation>/[<argument-0>/<argument-1>/...]>
#
# Each KES server API has an unique path - e.g. /v1/key/create/<key-name>.
# A client request is allowed if and only if no deny pattern AND at least one
# allow pattern matches the request URL path.
#
# A policy has zero (by default) or more assigned identities. However,
# an identity can never be assigned to more than one policy at the same
# time. So, one policy has N assigned identities but one identity is
# assigned to at most one policy.
#
# In general, each user/application should only have the minimal
# set of policy permissions to accomplish whatever it needs to do.
# Therefore, it is recommended to define policies based on workflows
# and then assign them to the identities.
# The following policy section shows some example policy definitions.
# Please remove/adjust to your needs.

- /v1/key/create/my-app*

cache:
# Cache expiry specifies when cache entries expire.
expiry:
# Period after which any cache entries are discarded.
# It determines how often the KES server has to fetch
# a secret key from the KMS.
#
# If not set, KES will default to an expiry of 5 minutes.
any: 5m0s
# Period after which all unused cache entries are discarded.
# It determines how often "not frequently" used secret keys
# must be fetched from the KMS.
#
# If not set, KES will default to an expiry of 30 seconds.
unused: 20s
# Period after which any cache entries in the offline cache
# are discarded.
# It determines how long the KES server can serve stateless
# requests when the KMS key store has become unavailable -
# e.g. due to a network outage.
#
# If not set, KES will disable the offline cache.
#
# Offline caching should only be enabled when trying to

# The console logging configuration. In general, the KES server
# distinguishes between (operational) errors and audit events.
# By default, the KES server logs error events to STDERR but
# does not log audit log events to STDOUT.
#
# The following log configuration only affects logging to console.
log:
# Enable/Disable logging error events to STDERR. Valid values
# are "on" or "off". If not set the default is "on". If no error
# events should be logged to STDERR it has to be set explicitly
# to: "off".
error: on
# Enable/Disable logging audit events to STDOUT. Valid values
# are "on" and "off". If not set the default is "off".
# Logging audit events to STDOUT may flood your console since
# there will be one audit log event per request-response pair.
#
# For tracing/monitoring audit logs take a look at the
# /v1/log/audit/trace API.
#
# Each audit event is a JSON object representing a request-response
# pair that contains the time, client identity, the API path, HTTP
# response status code etc.
