Offline Upgrade Backup and Restore Module¶

This page explains how to install or upgrade the backup and restore module after downloading it from the Download Center.

Load Images from Downloaded Package¶

You can load the images using one of the following two methods. When the container registry exists in the environment, it is recommended to use chart-syncer to synchronize the images to the container registry, as it is more efficient and convenient.

Method 1: Use chart-syncer to Synchronize Images¶

Using chart-syncer, you can upload the charts and their dependent image packages from the downloaded package to the container registry and Helm repository used by the installer.

First, find a node that can connect to the container registry and Helm repository (such as the Spark node), and create a load-image.yaml configuration file on the node, filling in the configuration information for the container registry and Helm repository.

1. Create load-image.yaml file

   Note

   All parameters in this YAML file are required.

   Helm repo already addedHelm repo not added

   If the current environment has already installed the chart repo, chart-syncer also supports exporting the chart as a tgz file.

   load-image.yaml

   source:
     intermediateBundlesPath: kcoral # (1)!
   target:
     containerRegistry: 10.16.10.111 # (2)!
     containerRepository: release.daocloud.io/kcoral # (3)!
     repo:
       kind: HARBOR # (4)!
       url: http://10.16.10.111/chartrepo/release.daocloud.io # (5)!
       auth:
         username: "admin" # (6)!
         password: "Harbor12345" # (7)!
     containers:
       auth:
         username: "admin" # (8)!
         password: "Harbor12345" # (9)!
   

   1. The path where the .tar.gz package is located after using chart-syncer
   2. Container registry address
   3. Container registry path
   4. Helm Chart repository type
   5. Helm repository address
   6. Container registry username
   7. Container registry password
   8. Helm repository username
   9. Helm repository password

   If the current node does not have a helm repo added, chart-syncer also supports exporting the chart as a tgz file and storing it in the specified path.

   load-image.yaml

   source:
     intermediateBundlesPath: kcoral # (1)!
   target:
     containerRegistry: 10.16.10.111 # (2)!
     containerRepository: release.daocloud.io/kcoral # (3)!
     repo:
       kind: LOCAL
       path: ./local-repo # (4)!
     containers:
       auth:
         username: "admin" # (5)!
         password: "Harbor12345" # (6)!
   

   1. The path where the .tar.gz package is located after using chart-syncer
   2. Container registry URL
   3. Container registry path
   4. Local path to the chart
   5. Container registry username
   6. Container registry password

2. Run the command to synchronize the images.

   charts-syncer sync --config load-image.yaml
   

Method 2: Load Images using Docker or containerd¶

Unpack and load the image files.

1. Extract the tar package.

   tar xvf kcoral.bundle.tar
   

   After successful extraction, you will get three files:

   • kcoral.bundle.tar

2. Load the images into Docker or containerd from the local directory.

   Dockercontainerd

   docker load -i images.tar
   

   ctr -n k8s.io image import images.tar
   

Upgrade¶

There are two upgrade methods. You can choose the appropriate upgrade method based on the preconditions:
