This finishes the work started at #1619 by introducing the following changes:
- You can now set `HELMFILE_TEMPDIR` and `CHARTIFY_TEMPDIR` as the directory to persist temporary values files rendered by helmfile and temporary charts generated by chartify. Note that chartify is used internally when you use kustomize integration or raw K8s manifests as a chart.
- Helmfile uses the hash sum of the release config and the values file content in the file name of the temporary values file.
In combination with `HELMFILE_TEMPDIR` and `CHARTIFY_TEMPDIR`, this enables helmfile to use the stable file names for temporary values files, which contribute to stabilize log messages like `Comparing release=appset, chart=PATH/TO/TEMPORARY/CHART`, where the `PATH/TO/TEMPORARY/CHART` had been randomized due to formerly random helmfile tempdir and temporary values file names, and random chartify tempdir.
You can try this feature with a script like:
```
tempdir=$(mktemp -d -t helmfile)
HELMFILE_TEMPDIR=${tempdir} CHARTIFY_TEMPDIR=${tempdir} helmfile diff
rm -rf ${tempdir}
```
`helmfile-diff` sorts multiple and concurrent helm-diff outputs and stabilizes writes to stdout.
It's required to use the stdout from helmfile-diff to detect if there was another change(s) between 2 points in time.
For example, terraform-provider-helmfile runs a helmfile-diff on `terraform plan` and another on `terraform apply`. `terraform`, by design, fails when helmfile-diff outputs were not equivalent. Stabilized helmfile-diff output rescues that.
This improves helmfile-apply with two things:
- Some users had timing-out issues or annoyed by huge output from helm-diff run as part of helmfile-apply on first install. `--skip-diff-on-install` skips running helm-diff for releases being newly installed, so that you can avoid those issues.
- Some users had difficultly or found it not straight-forward to install CRDs and custom resources from separate charts in one helmfile-apply (#1353). The new helmfile.yaml release field `disableValidationOnInstall: true` adds `--disable-validation` to helm-diff only for releases being newly released, which should mostly resolve the issue.
Resolves#1353
Please see the updated `advanced-features.md` for more details.
This is often used for adding common labels and annotations to any resources rendered from a Helm chart.
This deprecates the old `--retain-values` which was not working as intended.
Also see #1570 - there's now `--skip-cleanup` for `helmfile-template`, too.
This allows you to use helmfile-template output as a GitOps source, when the template output contains CRDs and you use Helm 3.
Helm 3 by default removes CRDs from the template output. If you want to git-commit helmfile-template containing CRDs for GitOps and you use Helm 3 for templating, the only way is provide this newly added `--include-crds` flag.
I had mistakenly inverted the necessary flag to turn off the legacy processing on selectors that should be used only for helmfile commands that does not support DAGs/needs.
Fixes#1552
`helm dep up` is now skipped while running helm-x/chartify when the chart/directory is obtained by running go-getter, or `skipDeps` is configured using a command-line flag, helmDefaults, or release configuration.
Resolves#1547
While using the `--debug` option, the output of helm seems to be printed triple times:

- The first with the prefixes `helm:MRAjW>` comes from <563fce4adf/pkg/helmexec/runner.go (L59-L65)>
- The second one with the format `exec: helm ... --debug: ...` comes from <563fce4adf/pkg/helmexec/exec.go (L369)>
- And the last are the logs of non-debug mode.
It sometimes makes the log a bit confusing, while I first time read the log, I thought helmfile executed helm command multiple times 😅.
Since we already piped helm outputs to stdout (the first), we remove the second logs.
Adds a basic support for Helm repositories hosted on Azure Container Registry (not OCI but classic ones). Add a new field to RepositorySpec to state that is externally managed and runs the `az-cli` command instead of the helm one to manage the repository.
* Parse and process helm version using github.com/Masterminds/semver/v3.
* Add --force-update only when Helm version >= 3.3.2, < 3.3.4.
See: https://github.com/helm/helm/pull/8777.
* Add test cases.
* Bump sprig to v3.1.0
test for mergeOverwrite
* Let mergo not (accidentally) try to merge unexported fields
This is also a good chance separate `HelmState` with the config loaded from YAML, which I had been wanting to do for a long time.

This is an experimental feature to support a potential use-case that you need to set namespaces in manifests rendered by `helmfile template`, WHEN the chart is unconventional hence does not have `namespace: {{ .Namespace }}`.
Rather than using this, you should usually fork/maintain or update/pull-request the chart to have `namespace: {{ .Namespace }}`.
Use this only when you CAN NOT do so, but still need to use `helmfile template`.
This is an attempt to log helm exec output as the helm exec command is running. It only prints if the --debug flag is set.

This adds `comonLabels` option to helmfile by:
- Adding `CommonLabels` to HelmState
- Changing `markExcludedReleases` and `ListReleases` functions to merge common labels into release labels
Resolves#1266
