This file can override several settings whenever the primary server is serving nodes
assigned to that environment.
environment.conf file is stored in an environment. It will be at the top level of its home
environment, next to the
For example, if your
environments are in the default directory (
test environment’s config file is located
# /etc/puppetlabs/code/environments/test/environment.conf # Puppet Enterprise requires $basemodulepath; see note below under "modulepath". modulepath = site:dist:modules:$basemodulepath # Use our custom script to get a git commit for the current state of the code: config_version = get_environment_commit.sh
environment.conf file uses the same INI-like format as
puppet.conf, with one
exception: it cannot contain config sections like [
main]. All settings in
environment.conf must be outside
any config section.
Relative paths in values
Most of the allowed settings accept file paths or lists of paths as their values.
If any of these paths are relative paths — that is, they start without a leading slash or drive letter — they are resolved relative to that environment’s main directory.
For example, if you
get_environment_commit.sh in the
test environment, Puppet uses the file
Interpolation in values
The settings in
environment.conf can use the values of
other settings as variables (such as
$codedir). Additionally, the
config_version setting can
use the special
$environment variable, which gets replaced with the name of the
The most useful variables to
environment.conf settings are:
$basemodulepath— useful for including the default module directories in the
modulepathsetting. We recommend Puppet Enterprise (PE) users include this in the value of
modulepath, because PE uses modules in the
basemodulepathto configure orchestration and other features.
$environment— useful as a command line argument to your
config_versionscript. You can interpolate this variable only in the
$codedir— useful for locating files.
environment.conffile can override these settings:
The list of directories Puppet loads modules from.If this setting isn’t set, the
modulepathfor the environment is:
That is, Puppet adds the environment’s modules directory to the value of the basemodulepath setting from
<MODULES DIRECTORY FROM ENVIRONMENT>:$basemodulepath
puppet.conf, with the environment’s modules getting priority. If the modules directory is empty of absent, Puppet only uses modules from directories in the basemodulepath. A directory environment never uses the global
The main manifest the primary server uses when compiling catalogs for this environment. This can be one file or a directory of manifests to be evaluated in alphabetical order. Puppet manages this path as a directory if one exists or if the path ends with a slash (
/) or dot (
If this setting isn’t set, Puppet uses the environment’s
manifestsdirectory as the main manifest, even if it is empty or absent. A directory environment never uses the global
A script Puppet can run to determine the configuration version.
Puppet automatically adds a config version to every catalog it compiles, as well as to messages in reports. The version is an arbitrary piece of data that can be used to identify catalogs and events.
You can specify an executable script that determines an environment’s config version by setting
config_versionin its environment.conf file. Puppet runs this script when compiling a catalog for a node in the environment, and use its output as the config version.Note: If you’re using a system binary like
git rev-parse, make sure to specify the absolute path to it. If
config_versionis set to a relative path, Puppet looks for the binary in the environment, not in the system’s
If this setting isn’t set, the config version is the time at which the catalog was compiled (as the number of seconds since January 1, 1970). A directory environment never uses the global
How long the primary server caches the data it loads from an environment. If present, this overrides the value of
environment_timeoutfrom puppet.conf. Unless you have a specific reason, we recommend only setting
environment_timeoutglobally, in puppet.conf. We also don’t recommend using any value other than
For more information about configuring the environment timeout, see the timeout section of the Creating Environments page.
