Configuration Options from oslo.config¶

When loading values from the sources defined by the following options, the precedence is as follows:

1. Command Line

2. Environment Variables

3. Config Files from --config-dir 1

4. Config Files from --config-file

5. Pluggable Config Sources

If a value is specified in multiple locations, the location used will be the one higher in the list. For example, if a value is specified both on the command line and in an environment variable, the value from the command line will be the one returned.

Files in a config dir are parsed in alphabetical order. Later files take precedence over earlier ones.

config_file¶

Type

list of filenames

Default

['~/.project/project.conf', '~/project.conf', '/etc/project/project.conf', '/etc/project.conf']

Path to a config file to use. Multiple config files can be specified, with values in later files taking precedence. Defaults to the value above. This option must be set from the command-line.

config_dir¶

Type

list of directory names

Default

['~/.project/project.conf.d/', '~/project.conf.d/', '/etc/project/project.conf.d/', '/etc/project.conf.d/']

Path to a config directory to pull *.conf files from. This file set is sorted, so as to provide a predictable parse order if individual options are over-ridden. The set is parsed after the file(s) specified via previous –config-file, arguments hence over-ridden options in the directory take precedence. This option must be set from the command-line.

config_source¶

Type

list

Default

[]

Lists configuration groups that provide more details for accessing configuration settings from locations other than local files.

driver¶

Type

string

Default

remote_file

This option has a sample default set, which means that its actual default value may vary from the one documented above.

The name of the driver that can load this configuration source.

uri¶

Type

URI

Default

https://example.com/my-configuration.ini

This option has a sample default set, which means that its actual default value may vary from the one documented above.

Required option with the URI of the extra configuration file’s location.

ca_path¶

Type

string

Default

/etc/ca-certificates

This option has a sample default set, which means that its actual default value may vary from the one documented above.

The path to a CA_BUNDLE file or directory with certificates of trusted CAs.

client_cert¶

Type

string

Default

/etc/ca-certificates/service-client-keystore

This option has a sample default set, which means that its actual default value may vary from the one documented above.

Client side certificate, as a single file path containing either the certificate only or the private key and the certificate.

client_key¶

Type

string

Default

<None>

Client side private key, in case client_cert is specified but does not includes the private key.
