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.

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
Resolves#246Fixes#252
This is a follow-up for #235.
We setup the default logger only after the flags are parsed successfully.
That's because we init the logger according to the --log-level flag value.
Fixes#233
Output on values render error:
```
err: failed to render [/Users/sstarcher/xxx/xxx/values.yaml], because of template: stringTemplate:10:18: executing "stringTemplate" at <requiredEnv "HELM_AC...>: error calling requiredEnv: required env var `HELM_ACCOUNT` is not set
```
Also removes panic and sets the output as `apps.Run()` can and will return errors. Panic makes no sense.
Changelog:
* improve error handling for value rendering
* only output if error exists
* add exit status
Adds the `--detailed-exitcode` to the `helmfile diff` command to return `1` on failure, and `2` when no error but diff is seen.
This feature requires the latest `helm-diff` containing https://github.com/databus23/helm-diff/pull/78, and `helm` containing https://github.com/helm/helm/pull/4367.
This is verified to work by manually running commands like the followings:
```bash
./helmfile --helm-binary helm211dev -f ./examples/helmfile.d diff --detailed-exitcode; echo $?
./helmfile --helm-binary helm211dev -f ./examples/helmfile.d diff; echo $?
```
Note that, in above example commands, `helm211dev` is a custom `helm` binary that is built from helm's master branch containing [the necessary enhancement to allow propagate non-zero plugin exit code](https://github.com/helm/helm/pull/4367).
Fixes#187
Changelog:
* fix: `helmfile -f dir/ -l k=v sync` fails on first helmfile w/ no match
* fix(ux): present the filename if the selector did not match any releases
```console
$ helmfile -f helmfile.d/ -l foo=bar sync
2018/07/12 23:37:29 specified selector did not match any releases in helmfile.d/00-backend.yaml
2018/07/12 23:37:29 specified selector did not match any releases in helmfile.d/01-frontend.yaml
2018/07/12 23:37:29 err: specified selector did not match any releases in any helmfile
```
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
Closes#93
Summary of changes:
- Adds the [uber-go-/zap](https://github.com/uber-go/zap) library for leveled logging (69040996e0bcbd2f211d0d8d576147027e928e3b)
- A new CLI arg `--log-level` which can take the values `debug` `info` `warn` `error` `fatal` `panic`. The default is `info`, and the existing `--quiet` flag is treated as `--log-level warn`
- All `helm.exec` calls are preceded by a one-line summary. The current information on the full helm command line arguments `exec: helm exec ... ` is only output at `debug` level. This means sensitive command line arguments which may include passwords and `--set` arguments should be hidden by default.
