Web Server and Web Services Configuration

Overview

Overview

While the node's web server is enabled by default, you are free to create a node HOCON configuration file to customize web service and web service functionality. See HOCON Properties Explained for additional details.

These are the available web server and web service properties for the com.tibco.ep.dtm.configuration.node configuration file:

administration

Communication settings for administration transport. This is optional. If unset, a set of default values apply. These defaults are set in the contain types.

webEnable

This optional property enables the administration web server by default. Setting to false disables all queries of the Runtime REST API, whether browser-based or not (for example, the web server cannot be enabled from command line property using epadmin start web). The epadmin start web command becomes disabled when webEnable=false, and epadmin display web remains enabled.

For example: 

webEnable = true
webPort

Administration web server port number. A value of 0 (default) means the node auto-generates the port number starting from 8008. Optional.

For example: 

webPort = 0
webUIEnable

This optional property enables the administration web server endpoint help UI by default, indicating the web interface is enabled and browser-based REST API queries are possible. False means browser-based REST API queries are not enabled though other queries are still possible through other methods.

For example: 

webUIEnable = true
webMaximumFileSizeMegabytes

Maximum file size in megabytes for downloaded files if webFileSizeHandling is set to LIMITED_FILE_SIZE. Value must be > 0. Optional. Default value is 5.

webFileSizeHandling

Controls the maximum size of downloaded files. FILE_UPLOAD_NOT_ALLOWED disables file downloads. LIMITED_FILE_SIZE restricts file size to the value specified in webMaximumFileSizeMegabytes. UNLIMITED_FILE_SIZE sets no limit on downloaded file size. Optional. Default value is LIMITED_FILE_SIZE.

webMaximumFileCacheTimeMinutes

Time in minutes to cache downloaded files if webFileCacheTimeHandling is set to TIMED_CACHE. Value must be > 0. Optional. Default value is 15.

webFileCacheTimeHandling

Controls the caching of downloaded files. CACHE_FOREVER stores the files forever; files are never deleted. DO_NOT_CACHE never stores downloaded files on the node; files are immediately deleted after use. TIMED_CACHE caches the files for the amount of time specified in webMaximumFileCacheTimeMinutes. Optional. Default value is TIMED_CACHE.

webServiceBindings

An optional binding between a web service name and authentication realm name. The binding provides a means to override the default node administration authentication realm (which is default-realm) for a specified web service. Supported web services: {admin-ui, admin, healthcheck, and metrics} and any user-created ones. Specifying no realm {} disables authentication for the specified web service.

authenticationRealmName

Authentication realm name for the specified web service binding. Required.

For example: 

webServiceBindings = {
  "admin" = {
     authenticationRealmName = "realm1"
     }
  "healthcheck" = {
     authenticationRealmName = "realm2"
     }
  "admin-ui" = {
     authenticationRealmName = "realm3"
     }
  "metrics" = {
     authenticationRealmName = "oidc-realm"
     }
  "my-web-service" = {} 
  //no authentication will be enabled for this service
}
