Offline Upgrade of Cluster Inspection Module

This page explains how to install or upgrade the cluster inspection module after downloading it from the Download Center.

Info

The term kocllie mentioned in the following commands or scripts is the internal development codename for the cluster inspection module.

Loading Images from the Downloaded Package

You can load the images in one of the following two ways. If there is an image repository in your environment, it is recommended to choose chart-syncer to synchronize the images to the image repository as it is more efficient and convenient.

Option 1: Synchronize Images with chart-syncer

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

First, locate a node (such as a spark node) that can connect to both the image repository and the Helm repository. On this node, create a load-image.yaml configuration file and fill in the necessary information about the image repository and the Helm repository.

  1. Create load-image.yaml file.

    Note

    All parameters in this YAML file are mandatory.

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

    load-image.yaml
    source:
  intermediateBundlesPath: kocllie # Path where the __load-image.yaml__ file is executed on the node.
target:
  containerRegistry: 10.16.10.111 # Image repository address
  containerRepository: release.daocloud.io/kocllie # Image repository path
  repo:
    kind: HARBOR # Helm Chart repository type
    url: http://10.16.10.111/chartrepo/release.daocloud.io # Helm repository address
    auth:
      username: "admin" # Image repository username
      password: "Harbor12345" # Image repository password
  containers:
    auth:
      username: "admin" # Helm repository username
      password: "Harbor12345" # Helm repository password

    If there is no helm repo added on the current node, chart-syncer also supports exporting the chart as a tgz file and storing it in the specified path.

    load-image.yaml
    source:
  intermediateBundlesPath: kocllie # Path where the __load-image.yaml__ file is executed on the node.
target:
  containerRegistry: 10.16.10.111 # Image repository URL
  containerRepository: release.daocloud.io/kocllie # Image repository path
  repo:
    kind: LOCAL
    path: ./local-repo # Local path to the chart
  containers:
    auth:
      username: "admin" # Image repository username
      password: "Harbor12345" # Image repository password

  2. Run the command to synchronize the images.

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

Option 2: Load Images using Docker or containerd

Unzip and load the image files.

  1. Unzip the tar package.

    tar xvf kocllie.bundle.tar

    After successful extraction, you will have three files:

    • hints.yaml
    • images.tar
    • original-chart

  2. Load the images from the tar file into Docker or containerd.

    docker load -i images.tar

    ctr -n k8s.io image import images.tar

Note

Each node needs to perform Docker or containerd image loading operation. After the loading is complete, tag the images to match the registry and repository used during installation.

Upgrade

There are two upgrade methods. You can choose the corresponding upgrade approach based on the prerequisite operations:

  1. Check if the cluster inspection Helm repository exists.

    helm repo list | grep kocllie

    If the result is empty or shows the following prompt, proceed to the next step; otherwise, skip the next step.

    Error: no repositories to show

  2. Add the cluster inspection Helm repository.

    helm repo add kocllie http://{harbor url}/chartrepo/{project}

  3. Update the cluster inspection Helm repository.

    helm repo update kocllie

  4. Select the version of cluster inspection module you want to install (it is recommended to install the latest version).

    helm search repo kocllie/kocllie --versions

    [root@master ~]# helm search repo kocllie/kocllie --versions
NAME                   CHART VERSION  APP VERSION  DESCRIPTION
kocllie/kocllie  0.20.0          v0.20.0       A Helm chart for kocllie
...

  5. Backup --set parameters.

    Before upgrading the cluster inspection module, it is recommended to run the following command to back up the --set parameters of the previous version.

    helm get values kocllie -n kocllie-system -o yaml > bak.yaml

  6. Update kocllie crds.

    helm pull kocllie/kocllie --version 0.6.0 && tar -zxf kocllie-0.6.0.tgz
kubectl apply -f kocllie/crds

  7. Run helm upgrade .

    Before the upgrade, it is recommended to modify the global.imageRegistry field in the bak.yaml file to the current image repository address being used.

    export imageRegistry={your image repository}

    helm upgrade kocllie kocllie/kocllie \
  -n kocllie-system \
  -f ./bak.yaml \
  --set global.imageRegistry=$imageRegistry \
  --version 0.6.0

  1. Backup --set parameters.

    Before upgrading the cluster inspection module, it is recommended to run the following command to back up the --set parameters of the previous version.

    helm get values kocllie -n kocllie-system -o yaml > bak.yaml

  2. Update kocllie crds.

    kubectl apply -f ./crds

  3. Run helm upgrade .

    Before the upgrade, it is recommended to modify the global.imageRegistry field in the bak.yaml file to the current image repository address being used.

    export imageRegistry={your image repository}

    helm upgrade kocllie . \
  -n kocllie-system \
  -f ./bak.yaml \
  --set global.imageRegistry=$imageRegistry
