## Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise [OS Photon Linux](https://vmware.github.io/photon/). Why choose BSI images?

- Hardened secure images of popular open source software with Near-Zero Vulnerabilities
- Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
- Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
- Software supply chain provenance attestation through in-toto
- First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in [our public catalog here](https://app-catalog.vmware.com/bitnami/apps). Note: Some data is only available with [commercial subscriptions to BSI](https://bitnami.com/).

## Introduction

Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.

This chart bootstraps an [ASP.NET Core](https://github.com/bitnami/containers/tree/main/bitnami/aspnet-core) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/aspnet-core
```

These commands deploy a ASP.NET Core application on the Kubernetes cluster in the default configuration.

> **Tip**: List all releases using `helm list`

## Configuration and installation details

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcesPreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### [Rolling VS Immutable tags](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Backup and restore

To back up and restore Helm chart deployments on Kubernetes, you need to back up the persistent volumes from the source deployment and attach them to a new deployment using [Velero](https://velero.io/), a Kubernetes backup/restore tool. Find the instructions for using Velero in [this guide](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-backup-restore-deployments-velero-index.html).

### Deploying your custom ASP.NET Core application

The ASP.NET Core chart allows you to deploy a custom application using one of the following methods:

- Using a Docker image containing your ASP.NET Core application ready to be executed.
- Cloning your ASP.NET Core application code from a GIT repository.
- Mounting your ASP.NET Core application from an existing PVC

#### Using a Docker image containing your ASP.NET Core application ready to be executed

You can build your own Docker image containing your ASP.NET Core application ready to be executed. To do so, overwrite the default image setting the `image.*` parameters, and set your custom command and arguments setting the `command` and `args` parameters:

```console
appFromExternalRepo.enabled=false
image.registry=docker.io
image.repository=your-image
image.tag=your-tag
command=[command]
args=[arguments]
```

#### Cloning your ASP.NET Core application code from a GIT repository

This is done using two different init containers:

- `clone-repository`: uses the [Bitnami GIT Image](https://github.com/bitnami/containers/tree/main/bitnami/git) to download the repository.
- `dotnet-publish`: uses the [Bitnami .Net SDK Image](https://github.com/bitnami/containers/tree/main/bitnami/dotnet-sdk) to build/publish the ASP.NET Core application.

To use this feature, set the `appFromExternalRepo.enabled` to `true` and set the repository and branch to use setting the `appFromExternalRepo.clone.repository` and `appFromExternalRepo.clone.revision` parameters. Then, specify the sub folder under the Git repository containing the ASP.NET Core app setting the `appFromExternalRepo.publish.subFolder` parameter. Finally, provide the start command to use setting the `appFromExternalRepo.startCommand`.

> Note: you can append any custom flag for the "dotnet publish" command setting the `appFromExternalRepo.publish.extraFlags` parameter.

For example, you can deploy a sample [OCMinimal](https://learn.microsoft.com/en-us/aspnet/core/performance/caching/output) using the parameters below:

```console
appFromExternalRepo.enabled=true
appFromExternalRepo.clone.repository=https://github.com/dotnet/AspNetCore.Docs.git
appFromExternalRepo.clone.revision=main
appFromExternalRepo.publish.aspnetcore/performance/caching/output/samples/7.x/
appFromExternalRepo.startCommand[0]=dotnet
appFromExternalRepo.startCommand[1]=OCMinimal.dll
```

#### Mounting your ASP.NET Core application from an existing PVC

If you previously created a PVC with your application code ready to be executed, you can mount it in the ASP.NET Core container setting the `appFromExistingPVC.enabled` parameter to `true`. Then, specify the name of your existing PVC setting the `appFromExistingPVC.existingClaim` parameter.

For example, if you created a PVC named `my-custom-apsnet-core-app` containing your application, use the parameters below:

```console
appFromExistingPVC.enabled=true
appFromExistingPVC.existingClaim=my-custom-apsnet-core-app
```

### Adding extra environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnvVars` property.

```yaml
kong:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error
```

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.

### Sidecars and Init Containers

If you have a need for additional containers to run within the same pod as the ASP.NET Core app (e.g. an additional metrics or logging exporter), you can do so via the `sidecars` config parameter. Simply define your container according to the Kubernetes container spec.

```yaml
sidecars:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
       containerPort: 1234
```

Similarly, you can add extra init containers using the `initContainers` parameter.

```yaml
initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234
```

### Deploying extra resources

There are cases where you may want to deploy extra objects, such a ConfigMap containing your app's configuration or some extra deployment with a micro service used by your app For covering this case, the chart allows adding the full specification of other objects using the `extraDeploy` parameter. The following example would create a ConfigMap including some app's configuration, and it will mount it in the ASP.NET Core app's container:

```yaml
extraDeploy: |-
  - apiVersion: v1
    kind: ConfigMap
    metadata:
      name: aspnet-core-configuration
      labels: {{- include "common.labels.standard" ( dict "customLabels" .Values.commonLabels "context" $ ) | nindent 6 }}
      {{- if .Values.commonAnnotations }}
      annotations: {{- include "common.tplvalues.render" ( dict "value" .Values.commonAnnotations "context" $ ) | nindent 6 }}
      {{- end }}
    data:
      appsettings.json: |-
        {
          "AllowedHosts": "*"
        }
extraVolumeMounts:
  - name: configuration
    mountPath: /app/config/
    readOnly: true
extraVolumes:
  - name: configuration
    configMap:
      name: aspnet-core-configuration
```

### Setting Pod's affinity

This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

### Ingress

This chart provides support for Ingress resources. If you have an ingress controller installed on your cluster, such as [nginx-ingress-controller](https://github.com/bitnami/charts/tree/main/bitnami/nginx-ingress-controller) or [contour](https://github.com/bitnami/charts/tree/main/bitnami/contour) you can utilize the ingress controller to serve your application.

To enable ingress integration, please set `ingress.enabled` to `true`.

#### Hosts

Most likely you will only want to have one hostname that maps to this ASP.NET Core installation. If that's your case, the property `ingress.hostname` will set it. However, it is possible to have more than one host. To facilitate this, the `ingress.extraHosts` object can be specified as an array. You can also use `ingress.extraTLS` to add the TLS configuration for extra hosts.

For each host indicated at `ingress.extraHosts`, please indicate a `name`, `path`, and any `annotations` that you may want the ingress controller to know about.

For annotations, please see [this document](https://github.com/kubernetes/ingress-nginx/blob/main/docs/user-guide/nginx-configuration/annotations.md). Not all annotations are supported by all ingress controllers, but this document does a good job of indicating which annotation is supported by many popular ingress controllers.

### RBAC parameters

| Name                                          | Description                                          | Value   |
| --------------------------------------------- | ---------------------------------------------------- | ------- |
| `serviceAccount.create`                       | Specifies whether a ServiceAccount should be created | `true`  |
| `serviceAccount.name`                         | The name of the ServiceAccount to use.               | `""`    |
| `serviceAccount.annotations`                  | Additional custom annotations for the ServiceAccount | `{}`    |
| `serviceAccount.extraLabels`                  | Additional labels for the ServiceAccount             | `{}`    |
| `serviceAccount.automountServiceAccountToken` | Automount service account token                      | `false` |

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release --set replicaCount=2 oci://REGISTRY_NAME/REPOSITORY_NAME/aspnet-core
```

The above command install ASP.NET Core chart with 2 replicas.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/aspnet-core
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/aspnet-core/values.yaml)

## Upgrading

### To 6.3.0

This version introduces image verification for security purposes. To disable it, set `global.security.allowInsecureImages` to `true`. More details at [GitHub issue](https://github.com/bitnami/charts/issues/30850).

### To 6.0.0

This major bump changes the following security defaults:

- `runAsUser` is changed from `0` to `1001`
- `runAsGroup` is changed from `0` to `1001`
- `readOnlyRootFilesystem` is set to `true`
- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.
- The `networkPolicy` section has been normalized amongst all Bitnami charts. It is added and enabled by default in all charts. This can be disabled by setting `networkPolicy.enabled=false`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

### To 3.0.0

The ASP.NET Core application version has been updated to the major version `6`. The init container of the chart have also been adapted to use the `6.x` files.

### To 2.0.0

Some of the chart values were changed to adapt to the latest Bitnami standards. More specifically:

- `strategy` was changed to `updateStrategy`
- `containerPort` was changed to `containerPorts.http`
- `service.port` was changed to `service.ports.http`

No issues should be expected when upgrading.

### To 1.0.0

[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

#### What changes were introduced in this major version?

- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
- After running `helm dependency update`, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts

#### Considerations when upgrading to this version

- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
