8936: Warn about disruptive effect of modifying blob_signature_ttl and blob_signing_key.

[arvados.git] / services / api / config / application.default.yml

# Do not use this file for site configuration. Create application.yml
# instead (see application.yml.example).
#
# The order of precedence is:
# 1. config/environments/{RAILS_ENV}.rb (deprecated)
# 2. Section in application.yml corresponding to RAILS_ENV (e.g., development)
# 3. Section in application.yml called "common"
# 4. Section in application.default.yml corresponding to RAILS_ENV
# 5. Section in application.default.yml called "common"

  ### Essential site configuration

  # The prefix used for all database identifiers to identify the record as
  # originating from this site.  Must be exactly 5 alphanumeric characters
  # (lowercase ASCII letters and digits).
  uuid_prefix: ~

  # secret_token is a string of alphanumeric characters used by Rails
  # to sign session tokens. IMPORTANT: This is a site secret. It
  # should be at least 50 characters.
  secret_token: ~

  # blob_signing_key is a string of alphanumeric characters used to
  # generate permission signatures for Keep locators. It must be
  # identical to the permission key given to Keep. IMPORTANT: This is
  # a site secret. It should be at least 50 characters.
  #
  # Modifying blob_signing_key will invalidate all existing
  # signatures, which can cause programs to fail (e.g., arv-put,
  # arv-get, and Crunch jobs).  To avoid errors, rotate keys only when
  # no such processes are running.

  #
  # If ARVADOS_WEBSOCKETS="ws-only", only websockets is served.
  #
  # If ARVADOS_WEBSOCKETS="false" or not set at all, only http is
  # served. In this case, you should have a separate process serving
  # websockets, and the address of that service should be given here
  # as websocket_address.
  #
  # If websocket_address is false (which is the default), the
  # discovery document will tell clients to use the current server as

  ### Limits, timeouts and durations
  ###

  # Lifetime (in seconds) of blob permission signatures generated by
  # the API server. This determines how long a client can take (after
  # retrieving a collection record) to retrieve the collection data
  # from Keep. If the client needs more time than that (assuming the
  # collection still has the same content and the relevant user/token
  # still has permission) the client can retrieve the collection again
  # to get fresh signatures.
  #
  # This must be exactly equal to the -blob-signature-ttl flag used by
  # keepstore servers.  Otherwise, reading data blocks and saving
  # collections will fail with HTTP 403 permission errors.
  #
  # Modifying blob_signature_ttl invalidates existing signatures; see
  # blob_signing_key note above.
  #
  # The default is 2 weeks.
  blob_signature_ttl: 1209600

  # Default lifetime for ephemeral collections: 2 weeks.
  default_trash_lifetime: 1209600

  # Maximum size (in bytes) allowed for a single API request.  This
  # limit is published in the discovery document for use by clients.
  # Note: You must separately configure the upstream web server or
  # proxy to actually enforce the desired maximum request size on the
  # server side.
  max_request_size: 134217728

  # Limit the number of bytes read from the database during an index
  # request (by retrieving and returning fewer rows than would
  # normally be returned in a single response).
  # Note 1: This setting never reduces the number of returned rows to
  # zero, no matter how big the first data row is.
  # Note 2: Currently, this only limits the
  # arvados.v1.collections.list API (GET /arvados/v1/collections), and
  # only takes the size of manifest_text into account. Other fields
  # (e.g., "properties" hashes) are not counted against this limit
  # when returning collections, and the limit is not applied at all
  # for other data types.
  max_index_database_read: 134217728

  # Maximum number of items to return when responding to a APIs that
  # can return partial result sets using limit and offset parameters
  # (e.g., *.index, groups.contents). If a request specifies a "limit"
  # parameter higher than this value, this value is used instead.
  max_items_per_response: 1000

  # The maximum number of compute nodes that can be in use simultaneously

  # go down.

  # These two settings control how frequently log events are flushed to the
