* feat(report): display summary of upgraded, deleted and error releases
* feat(#502): adds dep target in makefile
* feat(#502): removes vendor and fixes pristine in makefile
* 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.
Resolves#511
* Update docs about `helmfile delete` and `helmfile destroy`
* Improve code organization
To make sure it is still readable after upcoming changes to helmfile
* feat: `helmfile deps` to update dependencies of all the local charts
Resolves#450
* feat: helmfile updates repos and build deps by default
But not update deps. Use `helmfile deps` to update deps, and provide `--skip-deps` to skip updating repos and builds deps in sync/diff/apply/template
Resolves#415
* Improve integration test coverage
`helmfile test --concurency N` to set a concurrency number.
It is automatically ceiled at the number of releases just to reduce wasting computing resources.
Also, I've refactored the scatter-gather logic scattered across the code-base.
Resolves#433
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.

fixes https://github.com/roboll/helmfile/issues/412
the `apply` command first runs the `diff` command, which triggers the execution of the `cleanup` hooks at the end of the `diff`.
Perhaps in latest commits I unexpectedly changed it to require double Ctrl-C to actually interrupt. This fixes it so that one Ctrl-C exists helmfile.
On the way to the fix, I changed the exit-code to 128 + SIGNAL(2 for SIGINT, 15 for SIGTERM) according to common *nix commands.
Prevents helmfile from consuming unnecessarily much time in running `helm repo update` over and over.
helmfile now marks which repository was updated, and skip second and further `helm repo update` when all the `repositories` found in a helmfile.yaml was marked as already updated.
Let's say you had two helmfiles, the first one with repositories `foo` and `bar`, an the second one with only `bar`. `helmfile repos` will run `helm update repo` for the first helmfile, marking `foo` and `bar` as already updated. The second helmfile.yaml contains only `bar`, which is marked as already updated. So helmfile won't run `helm repo update` for the second.
This applies to all the helmfile command that results in `helm repo update`, like `repos`, `sync`, `diff` and so on.
Resolves#335
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 enables `helmfile lint` and `helmfile template` commands to fetch and untar all the required charts concurrently. The concurrency is configurable via the `--concurrency` flag, that defaults to `0`.
Ref #292
helmfile as of today ensures that all the targeted helmfile.yaml to have the specified environment defined in it.
That is, `helmfile --environment prod -f helmfile.d/ sync` fails if any helmfile under `helmfile.d/` is missing the `production` environment.
This changes the validation logic, so that helmfile fails only when all the helmfiles miss the environment.
Resolves#279
Enhance the `diff` functionality to be able to return affected releases that has any changes,
so that the succeeding `sync` can be run against only the affected releases.
This provides us extra idempotency.
Resolves#277
This removes --concurrenty flag from `helmfile template` and `helmfile lint`. YAGNI.
Also separates out the downloadCharts into a function so it can be used by lint too.
Fixes#288
`helmfile template` runs `helm template` over releases within the helmfiles, and provide you a stream of generated yaml documents of Kubernetes resources via stdout.
Resolves#283
Adds `--suppress-secrets` to `helmfile apply` and `helmfile diff`, so that the diff command omits the contents of secrets from its output. This is a security feature that should always be turned on for CI/CD use-cases.
With `--suppress-secrets`, the output when there is any change looks like:
```
Comparing bar stable/grafana
default, baz-grafana, Secret (v1) has changed:
+ Changes suppressed on sensitive content of type Secret
```
Resolves#269
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
`helmfile lint` works with relative chart reference (#252)
The tempalte function `readFile` accepts the path relative to helmfile.yaml
