roles/etherpad/README.md

+Role Name
+=========
+
+A brief description of the role goes here.
+
+Requirements
+------------
+
+Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
+
+Role Variables
+--------------
+
+A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
+
+Dependencies
+------------
+
+A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.
+
+Example Playbook
+----------------
+
+Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
+
+    - hosts: servers
+      roles:
+         - { role: username.rolename, x: 42 }
+
+License
+-------
+
+BSD
+
+Author Information
+------------------
+
+An optional section for the role authors to include contact information, or a website (HTML is not allowed).

+/*
+ * This file must be valid JSON. But comments are allowed
+ *
+ * Please edit settings.json, not settings.json.template
+ *
+ * Please note that starting from Etherpad 1.6.0 you can store DB credentials in
+ * a separate file (credentials.json).
+ *
+ *
+ * ENVIRONMENT VARIABLE SUBSTITUTION
+ * =================================
+ *
+ * All the configuration values can be read from environment variables using the
+ * syntax "${ENV_VAR}" or "${ENV_VAR:default_value}".
+ *
+ * This is useful, for example, when running in a Docker container.
+ *
+ * DETAILED RULES:
+ *   - If the environment variable is set to the string "true" or "false", the
+ *     value becomes Boolean true or false.
+ *   - If the environment variable is set to the string "null", the value
+ *     becomes null.
+ *   - If the environment variable is set to the string "undefined", the setting
+ *     is removed entirely, except when used as the member of an array in which
+ *     case it becomes null.
+ *   - If the environment variable is set to a string representation of a finite
+ *     number, the string is converted to that number.
+ *   - If the environment variable is set to any other string, including the
+ *     empty string, the value is that string.
+ *   - If the environment variable is unset and a default value is provided, the
+ *     value is as if the environment variable was set to the provided default:
+ *       - "${UNSET_VAR:}" becomes the empty string.
+ *       - "${UNSET_VAR:foo}" becomes the string "foo".
+ *       - "${UNSET_VAR:true}" and "${UNSET_VAR:false}" become true and false.
+ *       - "${UNSET_VAR:null}" becomes null.
+ *       - "${UNSET_VAR:undefined}" causes the setting to be removed (or be set
+ *         to null, if used as a member of an array).
+ *   - If the environment variable is unset and no default value is provided,
+ *     the value becomes null. THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF
+ *     ETHERPAD; if you want the default value to be null, you should explicitly
+ *     specify "null" as the default value.
+ *
+ * EXAMPLE:
+ *    "port":     "${PORT:9001}"
+ *    "minify":   "${MINIFY}"
+ *    "skinName": "${SKIN_NAME:colibris}"
+ *
+ * Would read the configuration values for those items from the environment
+ * variables PORT, MINIFY and SKIN_NAME.
+ *
+ * If PORT and SKIN_NAME variables were not defined, the default values 9001 and
+ * "colibris" would be used.
+ * The configuration value "minify", on the other hand, does not have a
+ * designated default value. Thus, if the environment variable MINIFY were
+ * undefined, "minify" would be null.
+ *
+ * REMARKS:
+ * 1) please note that variable substitution always needs to be quoted.
+ *
+ *    "port":     9001,            <-- Literal values. When not using
+ *    "minify":   false                substitution, only strings must be
+ *    "skinName": "colibris"           quoted. Booleans and numbers must not.
+ *
+ *    "port":     "${PORT:9001}"   <-- CORRECT: if you want to use a variable
+ *    "minify":   "${MINIFY:true}"     substitution, put quotes around its name,
+ *    "skinName": "${SKIN_NAME}"       even if the required value is a number or
+ *                                     a boolean.
+ *                                     Etherpad will take care of rewriting it
+ *                                     to the proper type if necessary.
+ *
+ *    "port":     ${PORT:9001}     <-- ERROR: this is not valid json. Quotes
+ *    "minify":   ${MINIFY}            around variable names are missing.
+ *    "skinName": ${SKIN_NAME}
+ *
+ * 2) Beware of undefined variables and default values: nulls and empty strings
+ *    are different!
+ *
+ *    This is particularly important for user's passwords (see the relevant
+ *    section):
+ *
+ *    "password": "${PASSW}"  // if PASSW is not defined would result in password === null
+ *    "password": "${PASSW:}" // if PASSW is not defined would result in password === ''
+ *
+ *    If you want to use an empty value (null) as default value for a variable,
+ *    simply do not set it, without putting any colons: "${ABIWORD}".
+ *
+ * 3) if you want to use newlines in the default value of a string parameter,
+ *    use "\n" as usual.
+ *
+ *    "defaultPadText" : "${DEFAULT_PAD_TEXT}Line 1\nLine 2"
