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
