Deploying the Multi-Cloud Collaboration Platform

Installing the Multi-Cloud Collaboration Platform

Install the multi-cloud collaboration platform using the CCE cluster.

Prerequisites

The CCE version is v1.22.x or later.
A private image repository whose cluster network is reachable and storage is greater than 50 GB is available.

Procedure

Download the installation package of the latest version from the Download Center.

CPU architecture	Version	Download URL
x86-64 (also known as AMD64)	v0.10.0	/
Arm64	v0.10.0	/

Decompress the installation package.

##Command for decompressing the installation package of the AMD64 architecture:  
tar -vxf offline-v0.10.0-amd64.tar

(Optional) Install nerdctl. (If containerd is used as the container runtime, install nerdctl on each worker node in the CCE cluster.)

wget https://github.com/containerd/nerdctl/releases/download/v1.4.0/nerdctl-1.4.0-linux-amd64.tar.gz   
tar -zxvf nerdctl-1.4.0-linux-amd64.tar.gz   
cp -a nerdctl /usr/local/bin/

Obtain the cluster configuration file clusterConfig.yaml from the offline/sample directory and modify the file as required.

Example configuration:

apiVersion: provision.daocloud.io/v1alpha3   
kind: ClusterConfig   
metadata:   
creationTimestamp: null   
spec:   
loadBalancer:   
type: cloudLB # Huawei Cloud ELB is recommended.   
istioGatewayVip: 10.5.14.XXX/32 (an EIP)   
insightVip: 10.5.14.XXX/32 (another EIP)   
fullPackagePath: /home/offline # Directory where the installation package is stored   
imagesAndCharts:   
type: external   
externalImageRepo: http://release.daocloud.io # Private image repository address

(Optional) Configure the manifest file. You can obtain the file from the offline/sample directory and modify the file as required.

## To enable HwameiStor, ensure that no default StorageClass exists in the cluster. If a default StorageClass exists, delete the configuration of the default StorageClass.

## If HwameiStor is not enabled, you can use the StorageClass automatically created by CCE. In this case, perform the following steps:
1. Change the automatically created csi-disk to the default StorageClass.
  kubectl patch storageclass csi-disk -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
2. Modify the /offline/sample/manifest.yaml file to disable HwameiStor.

Perform the private image repository authentication on all worker nodes.

Docker: Add authentication to the daemon.json file.

containerd: Add authentication to the containerd configuration file.
Install the multi-cloud collaboration platform.
1. Install dependencies.
  Go to the offline directory and install the dependencies.
```
cd /xxx/offline/utils   
./install_prerequisite.sh online full
```
  Wait until the installation is complete.
2. Install the multi-cloud collaboration platform.
  Figure 2 Installing the multi-cloud collaboration platform
```
/offline/dce5-installer install-app -m ./offline/sample/manifest.yaml -c ./offline/sample/clusterConfig.yaml
```
  Obtain parameter details through ./dce5-installer --help.
  - -z indicates the minimum installation.
  - -c specifies the cluster configuration file. You do not need to specify -c when NodePort is used for communications.
  - -d enables the debug mode.
  - -m specifies the manifest file used for installation.
  - --serial indicates that after this parameter is specified, all installation tasks are executed in serial mode.

When a message indicating that the installation is successful, use the URL displayed on the screen and the default username (admin) and password (changeme) to log in to the multi-cloud collaboration platform.
