Configuration files

This section will describe configuration format used in CCP.

File location

You can provide a path to file that you want to use as --config-file argument to ccp tool, otherwise it will be taken from the first existing location out of the following ones:

• ~/.ccp.yaml
• ~/.ccp/ccp.yaml
• /etc/ccp.yaml
• /etc/ccp/ccp.yaml

Note that you can use only one config file, if you want to split your file into several, you should use includes <includes>.

Format

Every config file is a simple YAML file with any number of YAML documents separated with --- line:

config_a: 1
config_b:
  config_c: 2
---
config_b:
  config_d: 3

All documents are deeply merged into one (only dicts are deeply merged, not lists or other structures). So above config will be equivalent to:

config_a: 1
config_b:
  config_c: 2
  config_d: 3

Includes

If you want to split your config over several files (e.g. keep sentitive config arguments separately or have a general config file part for several deployments) you can use includes. An include is a separate YAML document with !include tag and a list of files to be included in its place:

!include
- file_a
- file_b

If files are specified with relative paths, they are considered to be relative to file with includes. Absolute paths are taken as is.

All documents from files in include list are substituted in place of an include in order of appearance, so values from the latest file take precedence over values in former ones.

Note that include is just another YAML document in config file, so you can override values from include in following documents:

basic_value: 1
---
!include
- override_basic_value
---
override_value: from_include
