Compatible with nodes running Rudder 3.1 or higher.

Parameters

  • file: File name to edit (absolute path on the target node)
  • section: Name of the INI-style section under which the line should be added or modified (not including the [] brackets)
  • name: Name of the key to add or edit
  • value: Value of the key to add or edit

file_ensure_key_value_present_in_ini_section_${file}_{kept, repaired, not_ok, reached}


file_ensure_keys_values

Ensure that the file contains all pairs of "key separator value", with arbitrary separator between each key and its value

Compatible with nodes running Rudder 3.1 or higher.

Usage

This method ensures key-value pairs are present in a file.

Usage

This method will iterate over the key-value pairs in the dict, and:

  • If the key is not defined in the destination, add the key separator + value line.
  • If the key is already present in the file, replace the key separator + anything by key + separator + value

This method always ignores spaces and tabs when replacing (which means for example that key = value will match the = separator).

Keys are considered unique (to allow replacing the value), so you should use file_ensure_lines_present if you want to have multiple lines with the same key.

Example

If you have an initial file (/etc/myfile.conf) containing:

key1 = something
key3 = value3

To define key-value pairs, use the variable_dict or variable_dict_from_file methods.

For example, if you use the following content (stored in /tmp/data.json):

{
   "key1": "value1",
   "key2": "value2"
}

With the following policy:

# Define the `content` variable in the `configuration` prefix from the json file
variable_dict_from_file("configuration", "content", "/tmp/data.json")
# Enforce the presence of the key-value pairs
file_ensure_keys_values("/etc/myfile.conf", "configuration.content", " = ")

The destination file (/etc/myfile.conf) will contain:

key1 = value1
key3 = value3
key2 = value2

Parameters

  • file: File name to edit (absolute path on the target node)
  • keys: Name of the dict structure (without "${}") containing the keys (keys of the dict), and values to define (values of the dict)
  • separator: Separator between key and value (for example "=" or " ")

file_from_template_mustache

Build a file from a mustache template

Compatible with nodes running Rudder 3.1 or higher.

Usage

See file_from_template_type for general documentation about templates usage.

Syntax

Mustache is a logic-less templating language, available in a lot of languages, and used for file templating in CFEngine. The mustache syntax reference is https://mustache.github.io/mustache.5.html.

We will here describe the way to get agent data into a template. Ass explained in the general templating documentation, we can access various data in a mustache template.

The main specificity compared to standard mustache syntax of prefixes in all expanded values:

  • classes to access classes
  • vars to access all variables

Classes

Here is how to display content depending on classes definition:

{{#classes.my_class}}
   content when my_class is defined
{{/classes.my_class}}

{{^classes.my_class}}
   content when my_class is *not* defined
{{/classes.my_class}}

Note: You cannot use class expressions here.

Scalar variable

Here is how to display a scalar variable value (integer, string, …), if you have defined variable_string("variable_prefix", "my_variable", "my_value"):

{{{vars.variable_prefix.my_variable}}}

We use the triple {{{ }}} to avoid escaping html entities.

Iteration

Iteration is done using a syntax similar to scalar variables, but applied on container variables.

  • Use {{#vars.container}} content {{/vars.container}} to iterate
  • Use {{{.}}} for the current element value in iteration
  • Use {{{.key}}} for the key value in current element
  • Use {{{@}}} for the current element key in iteration

To iterate over a list, for example defined with:

variable_iterator("variable_prefix", "iterator_name", "a,b,c", ",")

Use the following file:

{{#vars.variable_prefix.iterator_name}}
{{{.}}} is the current iterator_name value
{{/vars.variable_prefix.iterator_name}}

Which will be expanded as:

a is the current iterator_name value
b is the current iterator_name value
c is the current iterator_name value

To iterate over a container defined by the following json file, loaded with variable_dict_from_file("variable_prefix", "dict_name", "path"):

{
   "hosts": [
       "host1",
       "host2"
   ],
   "files": [
       {"name": "file1", "path": "/path1", "users": [ "user1", "user11" ] },
       {"name": "file2", "path": "/path2", "users": [ "user2" ] }
   ],
   "properties": {
       "prop1": "value1",
       "prop2": "value2"
   }
}

Use the following template:

{{#vars.variable_prefix.dict_name.hosts}}
{{{.}}} is the current hosts value
{{/vars.variable_prefix.dict_name.hosts}}

# will display the name and path of the current file
{{#vars.variable_prefix.dict_name.files}}
{{{.name}}}: {{{.path}}}
{{/vars.variable_prefix.dict_name.files}}

# will display the users list of each file
{{#vars.variable_prefix.dict_name.files}}
{{{.name}}}:{{#users}} {{{.}}}{{/users}}
{{/vars.variable_prefix.dict_name.files}}


# will display the current properties key/value pair
{{#vars.variable_prefix.dict_name.properties}}
{{{@}}} -> {{{.}}}
{{/vars.variable_prefix.dict_name.properties}}

Which will be expanded as:

host1 is the current hosts value
host2 is the current hosts value

# will display the name and path of the current file
file1: /path1
file2: /path2

# will display the users list of each file
file1: user1 user11
file2: user2

# will display the current properties key/value pair
prop1 -> value1
prop2 -> value2

Note: Starting from CFEngine 3.7, you can use {{#-top-}} ... {{/-top-}} to iterate over the top level container.

Parameters

  • source_template: Source file containing a template to be expanded (absolute path on the target node)
  • destination: Destination file (absolute path on the target node)

Classes defined

file_from_template_${destination}_{kept, repaired, not_ok, reached}


file_from_template_type

Build a file from a template

Compatible with nodes running Rudder 3.1 or higher.

Usage

These methods write a file based on a provided template and the data available to the agent.

Usage

To use these methods (file_from_template_*), you need to have:

  • a template file
  • data to fill this template

The template file should be somewhere on the local file system, so if you want to use a file shared from the policy server, you need to copy it first (using file_copy_from_remote_source).

It is common to use a specific folder to store those templates after copy, for example in ${sys.workdir}/templates/.

The data that will be used while expanding the template is the data available in the agent at the time of expansion. That means:

  • CFEngine's sytem variables (${sys.*}, …) and classes (linux, ``)
  • data defined during execution (outcome classes of generic methods, …)
  • classes based on condition_ generic methods
  • data defined in ncf using variable_* generic methods, which allow for example to load data from local json or yaml files.

Template types

ncf currently supports two templating languages:

  • mustache templates, which are documented in file_from_template_mustache
  • CFEngine templates, which are a legacy implementation that is here for compatibility, and should not be used for new templates.

Example

Here is a complete example of templating usage:

The (basic) template file, present on the server in /PATH_TO_MY_FILE/ntp.conf.mustache (for syntax reference, see file_from_template_mustache):

{{#classes.linux}}
server {{{vars.configuration.ntp.hostname}}}
{{/classes.linux}}
{{^classes.linux}}
server hardcoded.server.example
{{/classes.linux}}

And on your local node in /tmp/ntp.json, the following json file:

{ "hostname": "my.hostname.example" }

And the following policy:

# Copy the file from the policy server
file_copy_from_remote_source("/PATH_TO_MY_FILE/ntp.conf.mustache", "${sys.workdir}/templates/ntp.conf.mustache")
# Define the `ntp` varibale in the `configuration` prefix from the json file
variable_dict_from_file("configuration", "ntp", "/tmp/ntp.json")
# Expand yout template
file_from_template_type("${sys.workdir}/templates/ntp.conf.mustache", "/etc/ntp.conf", "mustache")
# or
# file_from_template_mustache("${sys.workdir}/templates/ntp.conf.mustache", "/etc/ntp.conf")

The destination file will contain the expanded content, for example on a Linux node:

server my.hostname.example

Parameters

  • source_template: Source file containing a template to be expanded (absolute path on the target node)
  • destination: Destination file (absolute path on the target node)

file_replace_lines

Ensure that a line in a file is replaced by another one

Compatible with nodes running Rudder 3.1 or higher.

Usage

You can replace lines in a files, based on regular expression and captured pattern

Content can be captured in regular expression, and be reused with the notation ${match.1} (for first matched content), ${match.2} for second, etc, and the special captured group ${match.0} for the whole text.

Example

Here is an example to remove enclosing specific tags

file_replace_lines("/PATH_TO_MY_FILE/file", "<my>(.*)<pattern>", "my ${match.1} pattern")
