##### GENERAL CONFIG ######
###########################

# String. Log level to use throughout the application. Must be lower-case.
# Options: ["trace","debug","info","warn","error","fatal"]
# Default: "info"
log-level: "info"

# Bool. Log database queries when log-level is set to debug or trace.
# This setting produces verbose logs, so it's better to only enable it
# when you're trying to track an issue down.
# Options: [true, false]
# Default: false
log-db-queries: false

# String. Application name to use internally.
# Examples: ["My Application","gotosocial"]
# Default: "gotosocial"
application-name: "gotosocial"

# String. Hostname that this server will be reachable at. Defaults to localhost for local testing,
# but you should *definitely* change this when running for real, or your server won't work at all.
# DO NOT change this after your server has already run once, or you will break things!
# Examples: ["gts.example.org","some.server.com"]
# Default: "localhost"
host: "localhost"

# String. Domain to use when federating profiles. This is useful when you want your server to be at
# eg., "gts.example.org", but you want the domain on accounts to be "example.org" because it looks better
# or is just shorter/easier to remember.
# To make this setting work properly, you need to redirect requests at "example.org/.well-known/webfinger"
# to "gts.example.org/.well-known/webfinger" so that GtS can handle them properly.
# You should also redirect requests at "example.org/.well-known/nodeinfo" in the same way.
# An empty string (ie., not set) means that the same value as 'host' will be used.
# DO NOT change this after your server has already run once, or you will break things!
# Examples: ["example.org","server.com"]
# Default: ""
account-domain: ""

# String. Protocol to use for the server. Only change to http for local testing!
# This should be the protocol part of the URI that your server is actually reachable on. So even if you're
# running GoToSocial behind a reverse proxy that handles SSL certificates for you, instead of using built-in
# letsencrypt, it should still be https.
# Options: ["http","https"]
# Default: "https"
protocol: "https"

# String. Address to bind the GoToSocial server to.
# This can be an IPv4 address or an IPv6 address (surrounded in square brackets), or a hostname.
# Default value will bind to all interfaces.
# You probably won't need to change this unless you're setting GoToSocial up in some fancy way or
# you have specific networking requirements.
# Examples: ["0.0.0.0", "172.128.0.16", "localhost", "[::]", "[2001:db8::fed1]"]
# Default: "0.0.0.0"
bind-address: "0.0.0.0"

# Int. Listen port for the GoToSocial webserver + API. If you're running behind a reverse proxy and/or in a docker,
# container, just set this to whatever you like (or leave the default), and make sure it's forwarded properly.
# If you are running with built-in letsencrypt enabled, and running GoToSocial directly on a host machine, you will
# probably want to set this to 443 (standard https port), unless you have other services already using that port.
# This *MUST NOT* be the same as the letsencrypt port specified below, unless letsencrypt is turned off.
# Examples: [443, 6666, 8080]
# Default: 8080
port: 8080

# Array of string. CIDRs or IP addresses of proxies that should be trusted when determining real client IP from behind a reverse proxy.
# If you're running inside a Docker container behind Traefik or Nginx, for example, add the subnet of your docker network,
# or the gateway of the docker network, and/or the address of the reverse proxy (if it's not running on the host network).
# Example: ["127.0.0.1/32", "172.20.0.1"]
# Default: ["127.0.0.1/32"] (localhost)
trusted-proxies:
  - "127.0.0.1/32"

# Options: ["disable", "enable", "require"]
# Default: "disable"
db-tls-mode: "disable"

# String. Path to a CA certificate on the host machine for db certificate validation.
# If this is left empty, just the host certificates will be used.

instance-expose-peers: false

# Bool. Allow unauthenticated users to make queries to /api/v1/instance/peers?filter=suspended in order

#
# These settings are useful when one wants to daemonize GoToSocial and send logs
# to a specific place, either a local location or a syslog server. Most users will
# not need to touch these settings.

# Bool. Enable the syslog logging hook. Logs will be mirrored to the configured destination.
# Options: [true, false]

##### ADVANCED SETTINGS #####
#############################

# Advanced settings pertaining to http timeouts, security, cookies, and more.
#
# ONLY ADJUST THESE SETTINGS IF YOU KNOW WHAT YOU ARE DOING!
#
# Most users will not need to (and should not) touch these settings, since
# they are set to sensible defaults, and may break if they are changed.
#
# Nevertheless, they are provided for the sake of allowing server admins to
# tweak their instance for performance or security reasons.

# String. Value of the SameSite attribute of cookies set by GoToSocial.
# Defaults to 'lax' to ensure that the OIDC flow does not break, which is
# fine in most cases. If you want to harden your instance against CSRF attacks
# and don't mind if some login-related things might break, you can set this
# to 'strict' instead.
#
# For an overview of what this does, see:
# https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite
#
# Options: ["lax", "strict"]
# Default: "lax"
advanced-cookies-samesite: "lax"
