Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository.

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 deployment on a Kubernetes cluster using the Helm package manager.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Prerequisites

Kubernetes 1.23+
Helm 3.8.0+

Installing the Chart

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

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. However, in production workloads using resourcePreset is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the official Kubernetes documentation.

Rolling VS Immutable tags

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.

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:

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 to download the repository.
dotnet-publish: uses the Bitnami .Net SDK Image 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 using the parameters below:

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:

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.

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.

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.

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:

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.

As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common 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 or 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. 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.

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

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

Upgrading

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, 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 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 about migrating from Helm v2 to v3
