+
+# 关于
+
+Helmfile 是一个声明式Helm Chart管理工具
+
+> Helmfile 项目已经从原仓库 roboll/helmfile 转移到了 helmfile/helmfile。有关更多信息，请参见 roboll/helmfile#1824
+
+## 特性
+
+- 通过一个YAML集中管理集群中多个Helm Chart， 类似于Docker Compose统一管理Docker
+- 对Helm Chart根据部署环境区分管理
+- Helm Chart版本控制，比如指定版本范围、锁定某一版本
+- 快速识别 Kubernetes 集群内已经部署应用与新更改之间的差异
+- Helmfile支持Go Templates语法定义Helm Chart
+- 在部署阶段支持配置hook，可以执行脚本等，实现变量远程获取，报错清理，成功提醒等
+
+
+## 安装
+
+**方式1: 二进制安装**
+
+下载 [releases](https://github.com/helmfile/helmfile/releases)
+
+**方式2: 包管理工具**
+
+* Archlinux: `pacman -S helmfile`
+* openSUSE: `zypper in helmfile`
+* Windows: ([scoop](https://scoop.sh/)): `scoop install helmfile`
+* macOS ([homebrew](https://brew.sh/)): `brew install helmfile`
+
+**方式3: 容器**
+
+详细见：[run as a container](https://helmfile.readthedocs.io/en/latest/#running-as-a-container)
+
+> 安装后请运行一次 `helmfile init`。 检查[helm-diff](https://github.com/databus23/helm-diff) 等插件安装正确。
+
+## 使用
+
+让我们从最简单的 helmfile 开始，逐渐改进它以适应您的用例！
+
+假设表示您 helm releases 的期望状态的 helmfile.yaml 看起来像这样：
+
+```yaml
+repositories:
+- name: prometheus-community
+  url: https://prometheus-community.github.io/helm-charts
+
+releases:
+- name: prom-norbac-ubuntu
+  namespace: prometheus
+  chart: prometheus-community/prometheus
+  set:
+  - name: rbac.create
+    value: false
+```
+
+通过运行来同步您的Kubernetes集群状态到期望状态:
+
+```console
+helmfile apply
+```
+
+恭喜！您现在已经在集群内部运行了第一个Prometheus部署。

+### Adding dependencies without forking the chart
+
+With Helmfile, you can add chart dependencies to a Helm chart without forking it.
+
+An example `helmfile.yaml` that adds a `stable/envoy` dependency to the release `foo` looks like the below:
+
+```yaml
+repositories:
+- name: stable
+  url: https://charts.helm.sh/stable
+
+releases:
+- name: foo
+  chart: ./path/to/foo
+  dependencies:
+  - chart: stable/envoy
+    version: 1.5
+```
+
+When Helmfile encounters `releases[].dependencies`, it creates another temporary chart from `./path/to/foo` and adds the following `dependencies` to the `Chart.yaml`, so that you don't need to fork the chart.
+
+```yaml
+dependencies:
+- name: envoy
+  repo: https://charts.helm.sh/stable
+  condition: envoy.enabled
+```
+
+A Helm chart can have two or more dependencies for the same chart with different `alias`es. To give your dependency an `alias`, define it like you would do in a standard `Chart.yaml`:
+
+```yaml
+repositories:
+- name: stable
+  url: https://charts.helm.sh/stable
+
+releases:
+- name: foo
+  chart: ./path/to/foo
+  dependencies:
+  - chart: stable/envoy
+    version: 1.5
+    alias: bar
+  - chart: stable/envoy
+    version: 1.5
+    alias: baz
+```
+
+which will tweaks the temporary chart's `Chart.yaml` to have:
+
+
+```yaml
+dependencies:
+- alias: bar
+  name: envoy
+  repo: https://charts.helm.sh/stable
+  condition: bar.enabled
+- alias: baz
+  name: envoy
+  repo: https://charts.helm.sh/stable
+  condition: baz.enabled
+```
+
+Please see #649 for more context around this feature.
+
+After the support for adhoc dependency to local chart (#1765),
+you can even write local file paths relative to `helmfile.yaml` in `chart`:
+
+```yaml
+releases:
+- name: foo
+  chart: ./path/to/foo
+  dependencies:
+  - chart: ./path/to/bar
+```
+
+Internally, Helmfile creates another temporary chart from the local chart `./path/to/foo`, and modifies the chart's `Chart.yaml` dependencies to look like:
+
+```yaml
+dependencies:
+- alias: bar
+  name: bar
+  repo: file:///abs/path/to/bar
+  condition: bar.enabled
+```
+
+Please read https://github.com/roboll/helmfile/issues/1762#issuecomment-816341251 for more details.

+With Helmfile version v0.146.0 or later, you can add OCI chart to chart dependencies.
+
+An example `helmfile.yaml` that adds a OCI chart dependency to the release `foo` looks like the below:
+
+```yaml
+releases:
+- name: foo
+  chart: ./path/to/foo
+  dependencies:
+  - chart: oci://my-oci-registry/helm-repo/envoy
+    version: 1.5
+```
+
+### Lockfile per environment
+
+In some cases it can be handy for CI/CD pipelines to be able to roll out updates gradually for environments, such as staging and production while using the same
+set of charts. This can be achieved by using `lockFilePath` in combination with environments, such as:
+
+```yaml
+environments:
+  staging:
+  production
+
+---
+lockFilePath: .helmfile.{{ .Environment.Name}}.lock
+
+releases:
+- name: myapp
+  chart: charts/myapp

+# Towards Helmfile 1.0
+
+I'd like to make 3 breaking changes to Helmfile and mark it as 1.0, so that we can better communicate with the current and future Helmfile users about our stance on maintaining Helmfile.
+
+Note that every breaking change should have an easy alternative way to achieve the same goal achieved using the removed functionality.
+
+## The changes in 1.0
+
+1. [Forbid the use of `environments` and `releases` within a single helmfile.yaml.gotmpl part](#forbid-the-use-of-environments-and-releases-within-a-single-helmfileyamlgotmpl-part)

+4. [Remove `HELMFILE_SKIP_INSECURE_TEMPLATE_FUNCTIONS` in favor of `HELMFILE_DISABLE_INSECURE_FEATURES`](#remove-helmfile_skip_insecure_template_functions-in-favor-of-helmfile_disable_insecure_features)
+5. [The long deprecated `charts.yaml` has been finally removed](#the-long-deprecated-chartsyaml-has-been-finally-removed)
+
+### Forbid the use of `environments` and `releases` within a single helmfile.yaml.gotmpl part
+
+  - Helmfile currently relies on a hack called "double rendering" which no one understands correctly (I suppose) to solve the chicken-and-egg problem of rendering the helmfile template(which requires helmfile to parse `environments` as yaml first) and parsing the rendered helmfile as yaml(which requires helmfile to render the template first).
+  - By forcing (or print a big warning) the user to do separate helmfile parts for `environments` and `releases`, it's very unlikely Helmfile needs double-rendering at all.
+  - After this change, every helmfile.yaml written this way:
+
+        environments:
+          default:
+            values:
+            - foo: bar
+        releases:
+        - name: myapp
+          chart: charts/myapp
+          values:
+          - {{ .Values | toYaml | nindent 4 }}
+
+    must be rewritten like:
+
+        environments:
+          default:
+            values:
+            - foo: bar
+        ---
+        releases:
+        - name: myapp
+          chart: charts/myapp
+          values:
+          - {{ .Values | toYaml | nindent 4 }}
+
+    It might not be a deal breaker as you already had to separate helmfile parts when you need to generate `environments` dynamically:
+
+        environments:
+          default:
+            values:
+            - foo: bar
+        ---
+        environments:
+          default:
+            values:
+            - {{ .Values | toYaml | nindent 6}}}
+            - bar: baz
+        ---
+        releases:
+        - name: myapp
+          chart: charts/myapp
+          values:
+          - {{ .Values | toYaml | nindent 4 }}
+
+    If you're already using any helmfile.yaml files that are written in the first style, do start using `---` today! It will probably reveal and fix unintended template evaluations. If you start using `---` today, you won't need to do anything after Helmfile 1.0.
+
+### Force `.gotmpl` file extension for `helmfile.yaml` in case you want helmfile to render it as a go template before yaml parsing.
+
+  - As the primary maintainer of the project, I'm tired of explaining why Helmfile renders go template expressions embedded in a yaml comment. [The latest example of it](https://github.com/helmfile/helmfile/issues/127).
+  - When we first introduced helmfile the ability to render helmfile.yaml as a go template, I did propose it to require `.gotmpl` file extension to enable the feature. But none of active helmfile users and contributors at that time agreed with it (although I didn't have a very strong opinion on the matter either), so we enabled it without the extension. I consider it as a tech debt now.
+
+### Remove the `--args` flag from the `helmfile` command
+
+  - It has been provided as-is, and never intended to work reliably because it's fundamentally flawed because we have no way to specify which args to be passed to which `helm` commands being called by which `helmfile` command.
+  - However, I periodically see a new user finds it's not working and reporting it as a bug([the most recent example](https://github.com/roboll/helmfile/issues/2034#issuecomment-1147059088)). It's not a fault of the user. It's our fault that left this broken feature.
+  - Every use-case previsouly covered (by any chance) with `--args` should be covered in new `helmfile.yaml` fields or flags.
+
+### Remove `HELMFILE_SKIP_INSECURE_TEMPLATE_FUNCTIONS` in favor of `HELMFILE_DISABLE_INSECURE_FEATURES`
+
+  - This option didn't make much sense in practical. Generally, you'd want to disable all the insecure features altogether to make your deployment secure, or not disable any features. Disabling all is already possible via `HELMFILE_DISABLE_INSECURE_FEATURES `. In addition, `HELMFILE_SKIP_INSECURE_TEMPLATE_FUNCTIONS` literally made every insecure template function to silently skipped without any error or warning, which made debugging unnecessarily hard when the user accidentally used an insecure function.
+  - See https://github.com/helmfile/helmfile/pull/564 for more context.
+
+### The long deprecated `charts.yaml` has been finally removed
+
+Helmfile used to load `helmfile.yaml` or `charts.yaml` when you omitted the `-f` flag. `charts.yaml` has been deprecated for a long time but never been removed. We take v1 as a chance to finally remove it.
+
+## After 1.0
+
+We won't add any backward-incompatible changes while in 1.x, as long as it's inevitable to fix unseen important bug(s).
+
+We also quit saying [Helmfile is in its early days](https://github.com/helmfile/helmfile#status) in your README as... it's just untrue today.

+# Template Functions
+
+#### `env`
+The `env` function allows you to declare a particular environment variable as an optional for template rendering.
+If the environment variable is unset or empty, the template rendering will continue with an empty string as a value.
+
+```yaml
+{{ $envValue := env "envName" }}
+```
+
+#### `requiredEnv`
+The `requiredEnv` function allows you to declare a particular environment variable as required for template rendering.
+If the environment variable is unset or empty, the template rendering will fail with an error message.
+
+```yaml
+{{ $envValue := requiredEnv "envName" }}
+```
+
+> If the environment variable value starts with '/' (forward slash) and [Git for Windows](https://git-scm.com/download/win) is used, you must set `MSYS_NO_PATHCONV=1` to preserve values as-is, or the environment variable value will be prefixed with the `C:\Program Files\Git`. [reference](https://github.com/git-for-windows/build-extra/blob/main/ReleaseNotes.md#known-issues)
+
+#### `exec`
+The `exec` function allows you to run a command, returning the stdout of the command. When the command fails, the template rendering will fail with an error message.
+
+```yaml
+{{ $cmdOutpot := exec "./mycmd" (list "arg1" "arg2" "--flag1") }}
+```
+
+#### `envExec`
+The `envExec` function allows you to run a command with environment variables declared on-the-fly in addition to existing environment variables, returning the stdout of the command. When the command fails, the template rendering will fail with an error message.
+
+```yaml
+{{ $cmdOutpot := envExec (dict "envKey" "envValue") "./mycmd" (list "arg1" "arg2" "--flag1") }}
+```
+
+#### `readFile`
+The `readFile` function allows you to read a file and return its content as the function output. On failure, the template rendering will fail with an error message.
+
+```yaml
+{{ $fileContent := readFile "./myfile" }}
+```
+
+#### `readDir`
+The `readDir` function returns a list of the relative paths to the files contained within the directory. (No folders included. Use `readDirEntries` if you need folders too)
+
+```yaml
+{{ range $index,$item := readDir "./testdata/tmpl/sample_folder/" }}
+  {{- $itemSplit := splitList  "/" $item -}}
+  {{- if contains "\\" $item -}}
+  {{- $itemSplit = splitList "\\" $item -}}
+  {{- end -}}
+  {{- $itemValue := $itemSplit | last -}}
+  {{- $itemValue -}}
+{{- end -}}
+```
+
+#### `readDirEntries`
+The `readDirEntries` function returns a list of [DirEntry](https://pkg.go.dev/os#DirEntry) contained within the directory
+
+```yaml
+{{ range $index,$item := readDirEntries "./testdata/tmpl/sample_folder/" }}
+  {{- if $item.IsDir -}}
+  {{- $item.Name -}}
+  {{- end -}}
+{{- end -}}
+```
+
+#### `toYaml`
+The `toYaml` function allows you to convert a value to YAML string. When has failed, the template rendering will fail with an error message.
+
+```yaml
+{{ $yaml :=  $value | toYaml }}
+```
+
+#### `fromYaml`
+The `fromYaml` function allows you to convert a YAML string to a value. When has failed, the template rendering will fail with an error message.
+
+```yaml
+{{ $value :=  $yamlString | fromYaml }}
+```
+
+#### `setValueAtPath`
+The `setValueAtPath` function allows you to set a value at a path. When has failed, the template rendering will fail with an error message.
+
+```yaml
+{{ $value | setValueAtPath "path.key" $newValue }}
+```
+
+#### `get`
+The `get` function allows you to get a value at a path. when defaultValue not set. It will return nil. When has failed, the template rendering will fail with an error message.
+
+```yaml
+{{ $Getvalue :=  $value | get "path.key" "defaultValue" }}
+```
+
+#### `getOrNil`
+The `getOrNil` function allows you to get a value at a path. when defaultValue not set. It will return nil. When has failed, the template rendering will fail with an error message.
+
+```yaml
+{{ $GetOrNlvalue :=  $value | getOrNil "path.key" }}
+```
+
+#### `tpl`
+The `tpl` function allows you to render a template. When has failed, the template rendering will fail with an error message.
+
+```yaml
+{{ $tplValue :=  $value | tpl "{{ .Value.key }}" }}
+```
+
+#### `required`
+The `required` function returns the second argument as-is only if it is not empty. If empty, the template rendering will fail with an error message containing the first argument.
+
+```yaml
+{{ $requiredValue :=  $value | required "value not set" }}
+```
+
+#### `fetchSecretValue`
+The `fetchSecretValue` function parses the argument as a [vals](https://github.com/helmfile/vals) ref URL, retrieves and returns the remote secret value referred by the URL. In case it failed to access the remote secret backend for whatever reason or the URL was invalid, the template rendering will fail with an error message.
+
+```yaml
+{{ $fetchSecretValue :=  fetchSecretValue "secret/path" }}
+```
+
+#### `expandSecretRefs`
+The `expandSecretRefs` function takes an object as the argument and expands every [vals](https://github.com/helmfile/vals) secret reference URL embedded in the object's values. See ["Remote Secrets" page in our documentation](./remote-secrets.md) for more information.

+## Helmfile .Values vs Helm .Values
+
+Templating engine of Helmfile uses the same pipeline name `.Values` as Helm, so in some use-cases `.Values` of Helmfile and
+Helm can be seen in the same file. To distinguish these two kinds of `.Values`, Helmfile provides an alias `.StateValues`
+for its `.Values`.

+There are many organisations out there which would like to widen Kubernetes adoption but struggle with the requirement to keep all data confidential and follow best practices. For example, one best practice is to to implement a CI/CD process for all deployments including Helm charts. As part of this process we may want to keep secrets in private Vault secret storage, use Helm charts from a private chart museum, customised Helm values from a private Git repository and docker images from a private docker repository. ArgoCD alone cannot do all of these things at once, but we can achieve this if we configure it with Helmfile.
+
+This example is intended to show how you COULD use ArgoCD together with Helmfile to implement a fully private CI/CD system. Your deployment may be a litte bit different, or very different to this example. It's intended only as an example.
+
+The helm chart in this repo can be deployed with Helmfile, if you follow the prerequisites. In order for the deployment to work correctly, you will need to follow the prerequisites and update all of the `values.yaml` file entries with a `# TODO` comment.

+* SSO Setup: https://argoproj.github.io/argo-cd/operator-manual/user-management/microsoft/#azure-ad-app-registration-auth-using-oidc

+* Vault
+* Private Chartmuseum (Harbor)
+
+What are the interactions between the different systems?
+
+* ArgoCD will run on Kubernetes. We must use a custom build of ArgoCD as the official build doesn't ship with the runtime binaries which we will need to execute Helmfile and interact with Vault.
+* ArgoCD interacts with AzureAD for SSO. ArgoCD has to be configured as an enterprise app in Azure AD for authorization and authentication by an administrator. We put the client ID and client secrets into Vault for safe keeping.
+* ArgoCD interacts with Vault in order to pull secrets for customising Helm deployments. Sometimes we need to inject secrets into the values.yaml file of a Helm deployment. ArgoCD will use an AppRole for authentication into Vault, and this is done once during the deployment. The ArgoCD Vault credentials are saved in Vault for safe keeping.
+* ArgoCD may need to interact with a private Git server. This is so that ArgoCD can access the `helmfile.yaml` files before executing Helmfile. Additional configuration files (like `conf.d` and other `values.yaml`) files can be kept in here.
+* ArgoCD will authenticate to a private chart museum. This is so that we can keep the private helm charts private.
+
+# Prerequisites
+
+## Docker image
+
+* Build the docker image from the `argocd.dockerfile` file in this folder.
+* Upload the image to your private docker registry and make a note of the registry URL and tag.
+* Customise the `values.yaml` file in this folder.
+  Replace `argo-cd.global.image.repository` for the docker registry URL of your private registry.
+  Replace `argo-cd.global.image.tag` for the tag which you used to upload your private docker image.
+
+## Configure Single Sign-On for ArgoCD
+
+* Log into AzureAD as an administrator.
+* Create a new App Registration in your tenant for ArgoCD.
+* Create a new Client ID and client secret.
+* Save the client ID and client secret into your vault server.
+  - Save the client ID and client secret into Vault. Suggested keys: `internal/argocd/auth#azure_oidc_client_id` and `internal/argocd/auth#azure_oidc_client_secret`.
+* Update `values.yaml` for your deployment
+  - Update `argo-cd.server.config.oidc.config` - replace `SOME_AZURE_AD_TENANT` for your actual plaintext AzureAD tenant ID.
+  - Update `argo-cd.server.config.oidc.config` - replace `SOME_AZURE_AD_UUID` for your actual plaintext AzureAD client app ID.
+  - Verify that the Vault path specified in `argo-cd.config.secret.extra.oidc.azure.clientSecret` is the correct path in Vault.
+* Customise the ingress objects in the source to match what your expected external URL will be. Update `values.yaml` to have the correct values for the hostname you plan to use.
+  - `argo-cd.config.server.(url|hostname)`
+    ```yaml
+    url: 'https://my.argocd.deployment.org' # TODO
+    hostname: my.argocd.deployment.org      # TODO
+    ```
+
+## Configure authentication from ArgoCD into Vault (or read next section on how to disable it)
+
+* Read the documentation from Hashicorp on AppRoles. Provision a new AppRole for ArgoCD with policies.
+  - In the example the authentication path in Vault is assumed to be `auth/approle/login`. If that's not the case then update line 123 in `values.yaml`.
+* Store the AppRole credentials for ArgoCD in Vault. We will use Helmfile to pull them from here when we launch the chart.
+  - Suggested paths: `internal/vault/argocd#role_id` and `internal/vault/argocd#secret_id`
+* Verify that the Vault paths in `values.yaml` are correct
+  - `argo-cd.config.secret.extra.vault_role_id`
+  - `argo-cd.config.secret.extra.vault_secret_id`
+* Replace `ROLE_ID` and `SECRET_ID` in `values.yaml` (line 124) with the actual plaintext values (values key `argocd.server.config.configManagementPlugins`). This is not 100% secure but was the only way that I could manage to get the rest of the deployment working. I advise you add `values.yaml` to `.gitignore` after doing this step.
+
+## Disable Vault (optional)
+
+If you are not going to use Vault, then you need to update the values to get your deployment to use Helmfile.
+* If you are not going to use Vault, then remove the line in `values.yaml` that starts with `export VAULT_TOKEN=...`.
+
+## Configure authentication from ArgoCD into private Git repository
+
+* Create a new API user in your Git system (username + password auth). ArgoCD will use these credentials to pull `values.yaml` and `helmfile.yaml` for your project.
+* Save the username and password into Vault
+  - Recommended keys: `internal/git/users/argocd#username` and `internal/git/users/argocd#password`
+* Verify that the Vault paths in `values.yaml` are correct
+  - `argo-cd.config.secret.extra.git_username`
+  - `argo-cd.config.secret.extra.git_password`
+* Update the settings in `values.yaml` for repositories - remove the example Git URLS and replace with actual Git URLs for your project.
+  - `https://my.git.server.org/my-team/my-repo-one.git`
+  - `https://my.git.server.org/my-team/my-repo-two.git`
+
+## Configure authentication from ArgoCD to your private Docker registry and Chartmuseum
+
+* This guide is written with Harbor in mind, which is both a docker registry and chart museum. If you have separate systems in place you might need to configure these things separately.
+* Create a new set of credentials for Harbor and save them into Vault.
+  - Suggested paths: `internal/harbor/users/argocd#username`, `internal/harbor/users/argocd#username`.
+* Verify that the Vault paths in `values.yaml` are correct
+  - `argo-cd.config.secret.extra.harbor_username`
+  - `argo-cd.config.secret.extra.harbor_password`
+* Change the Helm URL on line 95 in `values.yaml` for the actual URL of your Helm Chartmuseum deployment.
+  - `https://my.harbor.deployment.org/chartrepo/my-project`
+
+# Deploy ArgoCD for the first time
+
+Once you've completed the prerequisites you are ready to deploy ArgoCD for the first time. There is a helmfile that you can use to do this.
+
+Steps:
+
+* Auth to Vault and Kubernetes
+* Add ArgoCD Helm repo
+  - ```bash
+    helm repo add argo https://argoproj.github.io/argo-helm
+    helm install --name argocd --namespace argocd argo/argo-cd
+    ```
+* Download dependencies (`helmfile dep update`)
+* Deploy chart (`helmfile apply`)
+  - If everything worked correctly, then ArgoCD should have deployed using your customised docker image into your cluster.
+
+* If the ingress deployed correctly then we should be able to access the UI: https://my.argocd.deployment.org
+* Grab the admin password from `argocd-initial-admin-secret secret` and use it to log into the UI.
+```bash
+    echo "<password>" | base64 -d
+```
+* Verify that SSO works by signing on with AzureAD.
+* Verify that Helmfile appears in the list of configured plugins in the UI.
+
+# Configure ArgoCD apps for deployment with Helmfile
+
+* Log into ArgoCD in the UI and configure a new app.
+* Make sure that it's using the Helmfile plugin.
+* For the source, select one of the Git repos which you configured previously.
+* Make sure that your Helm repo (including `helmfile.yaml` is present in the Git repository).
+* ArgoCD will pull the project from your private Git server and read the `helmfile.yaml` file.
+* ArgoCD will also execute helmfile directly in the container using the files checked out from your project.
+* If you configured ArgoCD with logins for Vault and private Chartmuseums, these can be used in ArgoCD by Helmfile.
+* You can use the diff feature and resource views in ArgoCD when using Helmfile. Unfortunately you can no longer use the `values.yaml` editor in the UI. You can change `values.yaml` for deployments by creating `values.yaml` files and committing them to the folders in your project Git repo. You can also customise them using `!vault` tags.
+
+If you would like an example, this ArgoCD + helmfile deployment can itself be deployed by ArgoCD + helmfile (you may need to drop the pods after you do deploy this way). Any other projects - just structure them in the same way as this example.
+
+Be careful when reconfiguring a project which was previously deploy by ArgoCD with Helmfile. There are some differences around the way in which annotations are used.
