Compiling the Huawei CSI Driver

This section describes the environmental requirements and steps of compiling Huawei CSI Driver

Compiler Environment

System	Go Version
Linux	>=1.10

Compilation steps

Step 1. Download the package and cd into the package, the structure is as follows:

- docs
  - en
  - zh
- src
  - csi
  - dev
  - proto
  - storage
  - tools
  - utils
  - vendor
- yamls
  - deploy
  - example

step 2. Change the keyText to a private value to prevent hacking. The length of the keyText is 32 characters. Such as:

keyText  = []byte("astaxie1279dkjajzmknm.ahkjkljl;k")

Step 3. Run following command to compile the Huawei CSI Driver

make -f Makefile-CSI PLATFORM=[X86|ARM]

Step 4. After the compilation is finished, a bin directory will be created in the current directory, the structure is as follows:

- bin
  - huawei-csi
  - passwdEncrypt

In addition, we also provide a way to directly download the installation package, click Release to obtain the corresponding version of the plug-in package

Deployment and Examples

Create Dockerfile and Make Huawei CSI Image

Ensure the docker has been installed on the host and host can access the networks in order to obtain some dependent software, then you can refer to the documentation and create your own Dockerfile.

docker build -f Dockerfile -t huawei-csi:*.*.* 

Export and import the image

docker save huawei-csi:*.*.* -o huawei-csi.tar

docker load -i huawei-csi.tar

Deploy The huawei-csi-rbac

Fill in the appropriate mirror version in huawei-csi-rbac.yaml, and then create the Huawei CSI Rbac.

kubectl create -f huawei-csi-rbac.yaml

Deploy the huawei-csi-configmap

Fill in the appropriate mirror version in huawei-csi-configmap.yaml, and then create the Huawei CSI Configmap

kubectl create -f huawei-csi-configmap.yaml

Deploy the huawei-csi-controller

Fill in the appropriate mirror version in huawei-csi-controller.yaml, and then create the Huawei CSI Controller service

kubectl create -f huawei-csi-controller.yaml

Deploy the huawei-csi-node

Fill in the appropriate mirror version in huawei-csi-node.yaml, and then create the Huawei CSI Node service

kubectl create -f huawei-csi-node.yaml

Verify CSI Driver is running

kubectl get pods -n kube-system

Also, we support our own logging service for the Huawei CSI Driver, the default directory is /var/log/huawei. When you encounter some driver issues, you can get some help from these logs.
