Kluctl project

Kluctl project configuration, found in the .kluctl.yaml file.

The .kluctl.yaml is the central configuration and entry point for your deployments. It defines which targets are available to invoke commands on.

Example

An example .kluctl.yaml looks like this:

targets:
  # test cluster, dev env
  - name: dev
    context: test.example.com
    args:
      environment_name: dev
  # test cluster, test env
  - name: test
    context: test.example.com
    args:
      environment_name: test
  # prod cluster, prod env
  - name: prod
    context: prod.example.com
    args:
      environment_name: prod

args:
  - name: environment

Allowed fields

targets

Please check the targets sub-section for details.

args

A list of arguments that can or must be passed to most kluctl operations. Each of these arguments is then available in templating via the global args object.

An example looks like this:

targets:
...

args:
  - name: environment
  - name: enable_debug
    default: false
  - name: complex_arg
    default:
      my:
        nested1: arg1
        nested2: arg2

These arguments can then be used in templating, e.g. by using {{ args.environment }}.

When calling kluctl, most of the commands will then require you to specify at least -a environment=xxx and optionally -a enable_debug=true

The following sub chapters describe the fields for argument entries.

name

The name of the argument.

default

If specified, the argument becomes optional and will use the given value as default when not specified.

The default value can be an arbitrary yaml value, meaning that it can also be a nested dictionary. In that case, passing args in nested form will only set the nested value. With the above example of complex_arg, running:

kluctl deploy -t my-target -a my.nested1=override`

will only modify the value below my.nested1 and keep the value of my.nested2.

Using Kluctl without .kluctl.yaml

It’s possible to use Kluctl without any .kluctl.yaml. In that case, all commands must be used without specifying the target.
