* feat: `helmfile destroy` deletes and purges releases
This adds `helmfile destroy` that is basically `helmfile delete --purge`.
I've also tweaked the behavior of `delete` and `destroy` for releases with `installed: false`, so that it becomes consistent with other helmfile commands.
It now delete releases only when `installed: true` AND the release is already installed.
**Why an another command?**
Because it's easy to remember, and it also makes it easier to iterate on your helmfile.
We've been using `helmfile delete` from the beginning of helmfile,
and several months have been passed since we've added `--purge` to it.
We noticed that we always prefer to use `--purge` so that we can quickly iterate on helmfile by
e.g. `helmfile delete --purge && helmfile sync`. But making `--purge` default makes the `delete` command inconsistent with the helm's `delete`.
`destroy`, on the other hand, doesn't have such problem, and is still easy to remember for terraform users.

* Update docs about `helmfile delete` and `helmfile destroy`
This basically allows to define both `releases` and `helmfiles` within a helmfile.yaml, so that you can start using sub-helmfiles easily, by extracting only reused releases.

This feature is supposed to help advanced use-cases like Conventional Directory Structure explained in several issues like #428.
Newly added configuration keys `templates`, `missingFileHandler`, and the ability to defer executing template expressions in `values`, `secrets`, `namespace`, and `chart` of releases allows you to abstract away repetitions into a reusable template:
```yaml
templates:
default: &default
missingFileHandler: Warn
namespace: "{{`{{ .Release.Name }}`}}"
chart: stable/{{`{{ .Release.Name }}`}}
values:
- config/{{`{{ .Release.Name }}`}}/values.yaml
- config/{{`{{ .Release.Name }}`}}/{{`{{ .Environment.Name }}`}}.yaml
secrets:
- config/{{`{{ .Release.Name }}`}}/secrets.yaml
- config/{{`{{ .Release.Name }}`}}/{{`{{ .Environment.Name }}`}}-secrets.yaml
releases:
- name: envoy
<<: *default
```
See the updated documentation for more details.
Resolves#428
The integration test was failing due to that it was still using `--auto-approve` flag which was removed. The documentation was still refering to `--auto-approve` and had no explanation about the new `--interactive` flag. This fixes all these issues.
This a follow up for #368
See https://github.com/roboll/helmfile/pull/374#issuecomment-425291468 for more context.
This allows using the environment values defined in the environments: section of helmfile.yaml to be used from other sections of the file.
This works by having two template renderers, the first-pass and the second-pass renderer.
The first-pass render renders a helmfile.yaml template with replacing template functions has side-effects with noop. So, use only funcs that don't have side-effects to compose your environment values.
Then the second-pass renderer renders the same helmfile.yaml template, but with the environment values loaded by the first-pass renderer.
The implementation uses a buffer instead of re-reading the file twice.
Resolves#297
This command syncs releases only if there is any difference between the desired and the current state. It asks for an confirmation by default. Provide `--auto-approve` flag after the `apply` command to skip it.
Resolves#205
Add tillerNamespace and kubeContext to helmDefaults. Also add merging of args capability.
People can start adding additional fields under helmDefaults on top of this. The additional fields are merged to args as long as they are implemented using the framework introduced by this commit.
Changelog:
* adding merging for helm defaults args and --args, adding tillernamspace, kubecontext to helmdefaults, adding getargs to lint command
* adding docs for helmdefaults
* checking if empty default values
