Importar um Cluster Construído em uma VM do SUSE® Virtualization

O Rancher permite que você importe máquinas virtuais do SUSE® Virtualization nas quais você instalou o Kubernetes.

Implantação

Pré-requisitos

O cluster Kubernetes é construído sobre VMs do SUSE® Virtualization.

Implantar Clusters de Convidados em Máquinas Virtuais do SUSE® Virtualization

Gere o arquivo de configuração do csi-driver usando o generate_addon_csi.sh script, que está disponível no repositório harvester/harvester-csi-driver.

Exemplo:

 ./generate_addon_csi.sh <serviceaccount name> <namespace> RKE2

A saída gerada será semelhante à seguinte:

Crie uma VM com dois arquivos de configuração de nuvem.

Instale o RKE2 na VM.

 sudo mkdir -p /etc/rancher/rke2
 echo "cni: calico
 disable-kube-proxy: false
 etcd-expose-metrics: false" | sudo tee /etc/rancher/rke2/config.yaml
 curl -sfL https://get.rke2.io | sudo sh -
 sudo systemctl enable rke2-server.service
 sudo systemctl start rke2-server.service

Verifique se o RKE2 está em execução na VM.

 sudo /var/lib/rancher/rke2/bin/kubectl --kubeconfig /etc/rancher/rke2/rke2.yaml get nodes

Importe a VM para o Rancher.

Na interface do Rancher, vá para Gerenciamento de Cluster > Clusters > Importar Existente > Genérico > Criar.

 # Run the command in the VM
 curl --insecure -sfL https://192.168.0.181:6443/v3/import/g5p2g2gtxw4564nktdl4nr5cwwvtwqp9zxd6dmhm5nc7vpnxmr9cfk_c-m-mzf28skd.yaml | sudo /var/lib/rancher/rke2/bin/kubectl --kubeconfig /etc/rancher/rke2/rke2.yaml apply -f -

Instale o Provedor de Nuvem Harvester.

No Painel do Cluster RKE2, vá para Apps > Charts > Provedor de Nuvem Harvester > Instalar.
Instale o Harvester CSI Driver.

No Painel do Cluster RKE2, vá para Apps > Charts > Harvester CSI Driver > Instalar.
