Install via Helm Chart

This installation method is recommended, and any component of HwameiStor can be easily installed through Helm Charts.

steps

  1. Prepare Helm tools

    Install the Helm command-line tool, see the Helm Documentation.

  2. Download hwameistor Repo

    Download and unzip the Repo file locally

    helm repo add hwameistor http://hwameistor.io/hwameistor

helm repo update hwameistor

helm pull hwameistor/hwameistor --untar

  3. Install HwameiStor

    helm install hwameistor ./hwameistor \
    -n hwameistor --create-namespace

Success

The installation is complete! To verify the installation effect, please refer to the next chapter Post-check.

Use the container registry image

Tip

The default registries are quay.io and ghcr.io. If you can’t access it, you can try to use the image sources provided by DaoCloud: quay.m.daocloud.io and ghcr.m.daocloud.io.

To switch the image of the registry, use --set to change the values ​​of these two parameters: k8sImageRegistry and hwameistorImageRegistry.

helm install hwameistor ./hwameistor \
    -n hwameistor --create-namespace \
    --set k8sImageRegistry=k8s-gcr.m.daocloud.io \
    --set hwameistorImageRegistry=ghcr.m.daocloud.io

Customize kubelet root directory

Warning

The default kubelet directory is /var/lib/kubelet. If your Kubernetes distribution uses a different kubelet directory, the parameter kubeletRootDir must be set.

For example, on Canonical's MicroK8s using /var/snap/microk8s/common/var/lib/kubelet/ as the kubelet directory, HwameiStor needs to be configured as follows Install:

helm install hwameistor ./hwameistor \
    -n hwameistor --create-namespace \
    --set kubeletRootDir=/var/snap/microk8s/common/var/lib/kubelet/

Production environment installation

The production environment requires:

  • Specify resource configuration
  • Avoid deploying to the Master node
  • Enables fast failover of controllers

Some recommended values ​​are provided in the values.extra.prod.yaml file, the specific usage is:

helm install hwameistor ./hwameistor \
    -n hwameistor --create-namespace \
    -f ./hwameistor/values.yaml \
    -f ./hwameistor/values.extra.prod.yaml

Warning

In a resource-constrained test environment, setting the above values ​​will cause the Pod to fail to start!

(Optional) Install DRBD

If you want to enable highly available volumes, you must install DRBD

helm pull hwameistor/drbd9-adapter --untar

helm install drbd9 ./drbd9-adapter \
    -n hwameistor --create-namespace

Domestic users can use the container registry daocloud.io/daocloud to speed up

helm install drbd-adapter ./drbd-adapter \
    -n hwameistor --create-namespace \
    --set registry=daocloud.io/daocloud
