Offline Install in a Standard Kubernetes Cluster¶

This page will guide you to install DCE Community package offline in a standard Kubernetes cluster, which is recommended in the production environment.

Click Online Install DCE Community to watch a video demo for online install.

Preparation¶

• Prepare a Kubernetes cluster. For resources required, see Cluster Resources for Installing DCE Community.

  • Create a StorageClass and set it the default SC
  • Install CoreDNS in the cluster
  • If there is only one node in the cluster, make sure you have removed taints for that node

• Install Dependencies.

  You must install certain versions of each dependency:

  • helm ≥ 3.11.1
  • skopeo ≥ 1.11.1
  • kubectl ≥ 1.25.6
  • yq ≥ 4.31.1

Download and install¶

1. Download and decompress the offline package of DCE Community on the controller node of your kubernetes cluster, or download and decompress the offline package from Download Center.

   Take VERSION=v0.18.0 as an example.

   export VERSION=v0.18.0
   wget https://qiniu-download-public.daocloud.io/DaoCloud_Enterprise/dce5/offline-community-$VERSION-amd64.tar
   tar -xvf offline-community-$VERSION-amd64.tar
   

2. Customize clusterConfig.yaml

   • If Console is exposed via NodePort (recommended only for PoC use cases), skip this step.

   • In non-public cloud environment (virtual/physical machine), please enable load balancer (metallb) to avoid NodePort instability caused by node IP changes. Plan your network carefully and set up 2 necessary VIPs. Here is an example of clusterConfig.yaml:

     yaml title="clusterConfig.yaml" apiVersion: provision.daocloud.io/v1alpha3 kind: ClusterConfig spec: loadBalancer: type: metallb istioGatewayVip: 10.6.229.10/32 insightVip: 10.6.229.11/32 fullPackagePath: absolute-path-of-the-offline-directory # (1)! imagesAndCharts: # (2)! type: external externalImageRepo: your-external-registry # (3)! # externalImageRepoUsername: admin # externalImageRepoPassword: Harbor123456

     1. path for decompressed offline package
     2. container registry
     3. container registry address, must be http or https

   • If it is a public cloud environment that already has a Kubernetes load balancer, set clusterConfig.yaml as follows:

     clusterConfig.yaml

     apiVersion: provision.daocloud.io/v1alpha3
     kind: ClusterConfig
     spec:
       loadBalancer:
         type: cloudLB
       fullPackagePath: absolute-path-of-the-offline-directory # (1)!
       imagesAndCharts: # (2)!
         type: external
         externalImageRepo: your-external-registry # (3)!
         # externalImageRepoUsername: admin
         # externalImageRepoPassword: Harbor123456
     

     1. path for decompressed offline package
     2. container registry
     3. container registry address, must be http or https

   • If Console is exposed via NodePort (recommended only for PoC use cases), set clusterConfig.yaml as follows:

     clusterConfig.yaml

     apiVersion: provision.daocloud.io/v1alpha3
     kind: ClusterConfig
     spec:
       loadBalancer:
         type: NodePort
       fullPackagePath: absolute-path-of-the-offline-directory # (1)!
       imagesAndCharts: # (2)!
         type: external
         externalImageRepo: your-external-registry # (3)!
         # externalImageRepoUsername: admin
         # externalImageRepoPassword: Harbor123456
     

     1. path for decompressed offline package
     2. container registry
     3. container registry address, must be http or https

3. Install DCE 5.0.

   ./dce5-installer install-app -c clusterConfig.yaml
   

   Note

   • Parameter -p specifies the offline directory to decompress the offline package.
   • For clusterConfig.yaml file settings, refer to Online Installation.
   • -z minimal install
   • -c specifies the cluster configuration file. You don't need to specify -c when using NodePort to expose the console.
   • -d enable debug mode
   • --serial specifies that all installation tasks are executed serially

4. After the installation is complete, the command line will prompt that the installation is successful. Congratulations!

   Now you can use the default account and password (admin/changeme) to explore the new DCE 5.0 through the URL prompted on the screen!

   

   Success

   It's recommended to write down the prompted URL for your next visit.

5. Before fully explore the features of DCE 5.0, you need to apply for a license. The Community package is provided for free. All you need to do is to apply for a free license.
