IOMesh快速安装指南
根据操作系统选择正确的脚本执行:
NOTE: Helm3 将会自动安装（如果没有找到的话）.
# Every node running IOMesh must have an IP address belongs to IOMESH_DATA_CIDR
export IOMESH_DATA_CIDR=10.234.1.0/24; curl -sSL https://iomesh.run/install_iomesh_el7.sh | sh -
然后等待IOMesh Cluster pods 就绪：
watch kubectl get --namespace iomesh-system pods
IOMesh 已经成功安装!
NOTE: If any error occurs during the installation process, the IOMesh resources which installed by the script will be reserved for troubleshooting. You can use the uninstall script to clean up all IOMesh resources installed in the k8s cluster:
curl -sSL https://iomesh.run/uninstall_iomesh.sh | sh -
自定义安装
高级安装指南，用于自定义安装：
Install CSI Snapshotter
该 CSI snapshotter 是 Kubernetes 实现的Container Storage Interface (CSI)的一部分。安装 CSI snapshotter 启用卷快照（ Volume Snapshot）功能。
NOTE: CSI Snapshotter should be installed once per cluster
下载并提取CSI external-snapshotter:
curl -LO https://github.com/kubernetes-csi/external-snapshotter/archive/release-2.1.tar.gz
tar -xf release-2.1.tar.gz && cd external-snapshotter-release-2.1
安装 Snapshot CRDs:
kubectl create -f ./config/crd
编辑 deploy/kubernetes/snapshot-controller/rbac-snapshot-controller.yaml 添加一个 namespace, eg. kube-system:
sed -i "s/namespace: default/namespace: kube-system/g" deploy/kubernetes/snapshot-controller/rbac-snapshot-controller.yaml
安装 snapshot controller, eg. kube-system:
kubectl apply -n kube-system -f ./deploy/kubernetes/snapshot-controller
- 等待 snapshot controller 就绪：
kubectl get sts snapshot-controller -n kube-system
NAME READY AGE
snapshot-controller 1/1 32s
安装 Helm3
NOTE: 如果 Helm3 已经安装略过本步骤.
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh
更多细节参考 Install Helm.
设置 Helm Repo
helm repo add iomesh http://iomesh.com/charts
安装 IOMesh Operator
下载 iomesh-operator.yaml 包含缺省配置参数:
helm show values iomesh/operator > iomesh-operator.yaml
定制 iomesh-operator.yaml:
安装 IOMesh Operator:
NOTE: replace
my-iomesh-operatorwith your release name.
helm install my-iomesh-operator iomesh/operator \
--namespace iomesh-system \
--create-namespace \
--wait
等待 IOMesh Operator就绪:
watch kubectl get --namespace iomesh-system pods
安装 IOMesh Cluster
下载 iomesh-values.yaml 包含缺省参数:
helm show values iomesh/iomesh > iomesh-values.yaml
定制 iomesh-values.yaml:
chunk:
dataCIDR: "10.234.1.0/24" # change to data network CIDR
安装 IOMesh Cluster:
NOTE: replace
my-iomeshwith your release name.
helm install my-iomesh iomesh/iomesh \
--create-namespace \
--namespace iomesh-system \
--values iomesh-values.yaml \
--wait
等待IOMesh Cluster pods就绪:
watch kubectl get --namespace iomesh-system pods
安装 IOMesh CSI driver
下载 iomesh-csi-driver.yaml 包含缺省参数:
helm show values iomesh/csi-driver > iomesh-csi-driver.yaml
获取 IOMesh 访问服务地址：
kubectl -n iomesh-system get svc iomesh-access
得到 ip address 在 CLUSTER_IP 段中：
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
iomesh-access ClusterIP 10.233.1.125 <none> 3260/TCP,10206/TCP,10201/TCP 12m
编辑 iomesh-csi-driver.yaml ，加入字段 metaAddr
例如:
driver:
metaAddr: "10.233.1.125:10206"
定制 iomesh-csi-driver.yaml:
NOTE: For Kubernetes worker node OS is
CentOS8orCoreOS, setmountIscsiLocktotrue. Otherwise, set it tofalse.
driver:
node:
driver:
mountIscsiLock: true
安装 IOMesh CSI driver：
NOTE: replace
my-iomesh-csi-driverwith your release name.
helm install my-iomesh-csi-driver iomesh/csi-driver \
--create-namespace \
--namespace iomesh-system \
--values iomesh-csi-driver.yaml \
--wait
等待 IOMesh Cluster pods就绪.
watch kubectl get --namespace iomesh-system pods
