## Sidecar injection for private GKE clusters
|
||||
|
||||
_**Sidecar injection for private clusters requires extra steps.**_
|
||||
|
||||
In private GKE clusters, an automatically created firewall rule for master access doesn't open port 4000, which Dapr needs for sidecar injection.
|
||||
|
||||
Review the relevant firewall rule:
|
||||
|
||||
To review the relevant firewall rule:
|
||||
```bash
|
||||
$ gcloud compute firewall-rules list --filter="name~gke-${CLUSTER_NAME}-[0-9a-z]*-master"
|
||||
```
|
||||

2. In case you need permissions the kubernetes dashboard (i.e. configmaps is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list configmaps in the namespace "default", etc.) execute this command
|
||||
## Troubleshooting
|
||||
|
||||
### Kubernetes dashboard permissions
|
||||
|
||||
Let's say you receive an error message similar to the following:

|
||||
```
|
||||
configmaps is forbidden: User "system:serviceaccount:kube-system:kubernetes-dashboard" cannot list configmaps in the namespace "default"
|
||||
```
|
||||
|
||||
Execute this command:
|
||||
|
||||
```bash
|
||||
kubectl create clusterrolebinding kubernetes-dashboard -n kube-system --clusterrole=cluster-admin --serviceaccount=kube-system:kubernetes-dashboard

## Prerequisites
|
||||

- [Docker](https://docs.docker.com/install/)
|

- [kubectl](https://kubernetes.io/docs/tasks/tools/)
|
||||
|

|
||||
|
||||
## Install and configure KiND
|
||||
|
||||
Make sure you follow one of the [Installation](https://kind.sigs.k8s.io/docs/user/quick-start) options for KiND.
|
||||
[Refer to the KiND documentation to install.](https://kind.sigs.k8s.io/docs/user/quick-start)
|
||||
|
||||
In case you are using Docker Desktop, double-check that you have performed the recommended [settings](https://kind.sigs.k8s.io/docs/user/quick-start#settings-for-docker-desktop) (4 CPUs and 8 GiB of RAM available to Docker Engine).
|
||||
If you are using Docker Desktop, verify that you have [the recommended settings](https://kind.sigs.k8s.io/docs/user/quick-start#settings-for-docker-desktop).
|
||||
|
||||
## Configure and create the KiND cluster
|
||||
|
||||
1. Create a file named `kind-cluster-config.yaml`, and paste the following:
|
||||
```yaml
|
||||
kind: Cluster
|
||||
apiVersion: kind.x-k8s.io/v1alpha4
|
||||
nodes:
|
||||
- role: control-plane
|
||||
kubeadmConfigPatches:
|
||||
- |
|
||||
kind: InitConfiguration
|
||||
nodeRegistration:
|
||||
kubeletExtraArgs:
|
||||
node-labels: "ingress-ready=true"
|
||||
extraPortMappings:
|
||||
- containerPort: 80
|
||||
hostPort: 8081
|
||||
protocol: TCP
|
||||
- containerPort: 443
|
||||
hostPort: 8443
|
||||
protocol: TCP
|
||||
- role: worker
|
||||
- role: worker
|
||||
```
|
||||
|
||||
This is going to request KiND to spin up a kubernetes cluster comprised of a control plane and two worker nodes. It also allows for future setup of ingresses and exposes container ports to the host machine.
|
||||
```yaml
|
||||
kind: Cluster
|
||||
apiVersion: kind.x-k8s.io/v1alpha4
|
||||
nodes:
|
||||
- role: control-plane
|
||||
kubeadmConfigPatches:
|
||||
- |
|
||||
kind: InitConfiguration
|
||||
nodeRegistration:
|
||||
kubeletExtraArgs:
|
||||
node-labels: "ingress-ready=true"
|
||||
extraPortMappings:
|
||||
- containerPort: 80
|
||||
hostPort: 8081
|
||||
protocol: TCP
|
||||
- containerPort: 443
|
||||
hostPort: 8443
|
||||
protocol: TCP
|
||||
- role: worker
|
||||
- role: worker
|
||||
```
|
||||
|
||||
2. Run the `kind create cluster` providing the cluster configuration file:
|
||||
This cluster configuration:
|
||||
- Requests KiND to spin up a Kubernetes cluster comprised of a control plane and two worker nodes.
|
||||
- Allows for future setup of ingresses.
|
||||
- Exposes container ports to the host machine.
|
||||
|
||||
```bash
|
||||
kind create cluster --config kind-cluster-config.yaml
|
||||
```
|
||||
1. Run the `kind create cluster` command, providing the cluster configuration file:
|
||||
|
||||
Wait until the cluster is created, the output should look like this:
|
||||
```bash
|
||||
kind create cluster --config kind-cluster-config.yaml
|
||||
```
|
||||
|

### Install Dapr (a private Dapr Helm chart)
|
||||
There are some scenarios where it's necessary to install Dapr from a private Helm chart, such as:
|
||||
- needing more granular control of the Dapr Helm chart
|
||||
- having a custom Dapr deployment
|
||||
- pulling Helm charts from trusted registries that are managed and maintained by your organization

### Use Mariner-based images
|
||||
|
||||
The default container images pulled on Kubernetes are based on [*distroless*](https://github.com/GoogleContainerTools/distroless).
|
||||
|
||||
Alternatively, you can use Dapr container images based on Mariner 2 (minimal distroless). [Mariner](https://github.com/microsoft/CBL-Mariner/), officially known as CBL-Mariner, is a free and open-source Linux distribution and container base image maintained by Microsoft. For some Dapr users, leveraging container images based on Mariner can help you meet compliance requirements.
|
||||
|
||||
To use Mariner-based images for Dapr, you need to add `-mariner` to your Docker tags. For example, while `ghcr.io/dapr/dapr:latest` is the Docker image based on *distroless*, `ghcr.io/dapr/dapr:latest-mariner` is based on Mariner. Tags pinned to a specific version are also available, such as `{{% dapr-latest-version short="true" %}}-mariner`.

description: "How to run Dapr apps on Kubernetes clusters with Windows nodes"
|
||||
---
|
||||
|
||||
Dapr supports running on Kubernetes clusters with Windows nodes. You can run your Dapr microservices exclusively on Windows, exclusively on Linux, or a combination of both. This is helpful to users who may be doing a piecemeal migration of a legacy application into a Dapr Kubernetes cluster.
|
||||
Dapr supports running your microservices on Kubernetes clusters on:
|
||||
- Windows
|
||||
- Linux
|
||||
- A combination of both
|
||||
|
||||
Kubernetes uses a concept called node affinity so that you can denote whether you want your application to be launched on a Linux node or a Windows node. When deploying to a cluster which has both Windows and Linux nodes, you must provide affinity rules for your applications, otherwise the Kubernetes scheduler might launch your application on the wrong type of node.
|
||||
This is especially helpful during a piecemeal migration of a legacy application into a Dapr Kubernetes cluster.
|
||||
|
||||
## Pre-requisites
|
||||
Kubernetes uses a concept called **node affinity** to denote whether you want your application to be launched on a Linux node or a Windows node. When deploying to a cluster which has both Windows and Linux nodes, you must provide affinity rules for your applications, otherwise the Kubernetes scheduler might launch your application on the wrong type of node.
|
||||
|
||||
You will need a Kubernetes cluster with Windows nodes. Many Kubernetes providers support the automatic provisioning of Windows enabled Kubernetes clusters.
|
||||
## Prerequisites
|
||||
|

Dapr can be configured to run on any supported versions of Kubernetes. To achieve this, Dapr begins by deploying the `dapr-sidecar-injector`, `dapr-operator`, `dapr-placement`, and `dapr-sentry` Kubernetes services. These provide first-class integration to make running applications with Dapr easy.
|
||||
- **dapr-operator:** Manages [component]({{< ref components >}}) updates and Kubernetes services endpoints for Dapr (state stores, pub/subs, etc.)
|
||||
- **dapr-sidecar-injector:** Injects Dapr into [annotated](#adding-dapr-to-a-kubernetes-deployment) deployment pods and adds the environment variables `DAPR_HTTP_PORT` and `DAPR_GRPC_PORT` to enable user-defined applications to easily communicate with Dapr without hard-coding Dapr port values.
|
||||
- **dapr-placement:** Used for [actors]({{< ref actors >}}) only. Creates mapping tables that map actor instances to pods
|
||||
- **dapr-sentry:** Manages mTLS between services and acts as a certificate authority. For more information read the [security overview]({{< ref "security-concept.md" >}}).

It is recommended to set soft memory limits on the Dapr sidecar when you have set up memory limits.

|
||||
waiting to be double of the last amount of memory present in the heap when it was run, which is the default behavior

Set soft memory limits on the Dapr sidecar when you've set up memory limits.

Waiting is the default behavior of the [garbage collector](https://tip.golang.org/doc/gc-guide#Memory_limit) used in Go, and can lead to OOM Kill events.

## High availability mode
|
||||
|
||||
When deploying Dapr in a production-ready configuration, it is recommend to deploy with a highly available (HA) configuration of the control plane, which creates 3 replicas of each control plane pod in the dapr-system namespace. This configuration allows the Dapr control plane to retain 3 running instances and survive individual node failures and other outages.
|
||||
When deploying Dapr in a production-ready configuration, it's best to deploy with a high availability (HA) configuration of the control plane. This creates three replicas of each control plane pod in the `dapr-system` namespace, allowing the Dapr control plane to retain three running instances and survive individual node failures and other outages.
|
||||
|
||||
For a new Dapr deployment, the HA mode can be set with both the [Dapr CLI]({{< ref "kubernetes-deploy.md#install-in-highly-available-mode" >}}) and with [Helm charts]({{< ref "kubernetes-deploy.md#add-and-install-dapr-helm-chart" >}}).

For a new Dapr deployment, HA mode can be set with both:

|
||||
- [Helm charts]({{< ref "kubernetes-deploy.md#add-and-install-dapr-helm-chart" >}})
|
||||
|
||||
For an existing Dapr deployment, enabling the HA mode requires additional steps. Please refer to [this paragraph]({{< ref "#enabling-high-availability-in-an-existing-dapr-deployment" >}}) for more details.

Dapr supports zero-downtime upgrades. The upgrade path includes the following steps:
|
||||
## Upgrade Dapr with Helm
|
||||
|
||||
1. Upgrading a CLI version (optional but recommended)
|
||||
2. Updating the Dapr control plane
|
||||
3. Updating the data plane (Dapr sidecars)
|
||||
Dapr supports zero-downtime upgrades in the following steps.
|
||||
|
||||
### Upgrading the CLI
|
||||
### Upgrade the CLI (recommended)
|
||||
|
||||
To upgrade the Dapr CLI, [download the latest version](https://github.com/dapr/cli/releases) of the CLI and ensure it's in your path.
|
||||
Upgrading the CLI is optional, but recommended.
|
||||
|
||||
### Upgrading the control plane
|
||||
1. [Download the latest version](https://github.com/dapr/cli/releases) of the CLI.
|
||||
1. Verify the Dapr CLI is in your path.
|
||||
|
||||
See [steps to upgrade Dapr on a Kubernetes cluster]({{< ref "kubernetes-upgrade.md#helm" >}}).

||||
### Updating the data plane (sidecars)
|
||||
[Upgrade Dapr on a Kubernetes cluster]({{< ref "kubernetes-upgrade.md#helm" >}}).
|
||||
|
||||
The last step is to update pods that are running Dapr to pick up the new version of the Dapr runtime.
|
||||
To do that, simply issue a rollout restart command for any deployment that has the `dapr.io/enabled` annotation:
|
||||
### Update the data plane (sidecars)
|
||||
|
||||
```bash
|
||||

### Enable high availability in an existing Dapr deployment

1. Delete the existing placement stateful set:

1. Delete the existing placement stateful set.
|
||||
|
||||
```bash
|
||||
kubectl delete statefulset.apps/dapr-placement-server -n dapr-system
|
||||
```
|
||||
|
||||
1. Issue the upgrade command:
|
||||
You delete the placement stateful set because, in HA mode, the placement service adds [Raft](https://raft.github.io/) for leader election. However, Kubernetes only allows for limited fields in stateful sets to be patched, subsequently failing upgrade of the placement service.
|
||||
|
||||
Deletion of the existing placement stateful set is safe. The agents reconnect and re-register with the newly created placement service, which persist its table in Raft.
|
||||
|
||||
1. Issue the upgrade command.
|
||||
|
||||
```bash
|
||||
helm upgrade dapr ./charts/dapr -n dapr-system --set global.ha.enabled=true
|
||||
```
|
||||
|
||||
You delete the placement stateful set because, in the HA mode, the placement service adds [Raft](https://raft.github.io/) for leader election. However, Kubernetes only allows for limited fields in stateful sets to be patched, subsequently failing upgrade of the placement service.

description: "Configure the Dapr sidecar to mount Pod Volumes"
|

---
|
||||
|
||||
## Introduction
|
||||
|
||||
The Dapr sidecar can be configured to mount any Kubernetes Volume attached to the application Pod. These Volumes can be accessed by the `daprd` (sidecar) container in _read-only_ or _read-write_ modes. If a Volume is configured to be mounted but it does not exist in the Pod, Dapr logs a warning and ignores it.
|
||||
|
||||
For more information on different types of Volumes, check the [Kubernetes documentation](https://kubernetes.io/docs/concepts/storage/volumes/).

You can set the following annotations in your deployment YAML:
|
||||
|
||||
1. **dapr.io/volume-mounts**: for read-only volume mounts
|
||||
1. **dapr.io/volume-mounts-rw**: for read-write volume mounts

| Annotation | Description |
|

| ---------- | ----------- |
|

| `dapr.io/volume-mounts-rw` | For read-write volume mounts |

These annotations are comma separated pairs of `volume-name:path/in/container`. Verify the corresponding Volumes exist in the Pod spec.

Within the official container images, Dapr runs as a process with user ID (UID) `65532`. Make sure that folders and files inside the mounted Volume are writable or readable by user `65532` as appropriate.

Although you can mount a Volume in any folder within the Dapr sidecar container, prevent conflicts and ensure smooth operations going forward by placing all mountpoints within one of these two locations, or in a subfolder within them:

## Examples
|
||||
|
||||
In the example Deployment resource below, `my-volume1` and `my-volume2` are available inside the sidecar container at `/mnt/sample1` and `/mnt/sample2` respectively, in read-only mode. `my-volume3` is available inside the sidecar container at `/tmp/sample3` in read-write mode.

### Custom secrets storage using local file secret store
|
||||
|
||||
Since any type of Kubernetes Volume can be attached to the sidecar, you can use the local file secret store to read secrets from a variety of places. For example, if you have a Network File Share (NFS) server running at `10.201.202.203`, with secrets stored at `/secrets/stage/secrets.json`, you can use that as a secrets storage.
|
||||
|
||||
1. Configure the application pod to mount the NFS and attach it to the Dapr sidecar.

||||

||||
