Offline Upgrade Service Mesh Module

This page explains how to install or upgrade after downloading the Service Mesh module.

Info

The mspider mentioned in the following commands or scripts is the internal development code name of the Service Mesh module.

Load Image from Installation Package

You can load the image in one of the following two ways. When there is a container registry in the environment, it is recommended to use chart-syncer to synchronize the image to the container registry, as this method is more efficient and convenient.

Synchronize Image to Container Registry with chart-syncer

  1. Create load-image.yaml

    Note

    All parameters in this YAML file are required. You need a private container registry and modify the relevant configuration.

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

    load-image.yaml
    source:
  intermediateBundlesPath: mspider-offline # (1)!
target:
  containerRegistry: 10.16.10.111 # (2)!
  containerRepository: release.daocloud.io/mspider # (3)1
  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. Relative path to run the charts-syncer command, not the relative path between this YAML file and the offline package
    2. Change to your container registry url
    3. Change to your container registry
    4. Can be any other supported Helm Chart repository category
    5. Change to chart repo url
    6. Your container registry username
    7. Your container registry password
    8. Your container registry username
    9. Your container registry password

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

    load-image.yaml
    source:
  intermediateBundlesPath: mspider-offline # (1)!
target:
  containerRegistry: 10.16.10.111 # (2)!
  containerRepository: release.daocloud.io/mspider # (3)!
  repo:
    kind: LOCAL
    path: ./local-repo # (4)!
  containers:
    auth:
      username: "admin" # (5)!
      password: "Harbor12345" # (6)!
    1. Relative path to run the charts-syncer command, not the relative path between this YAML file and the offline package
    2. Change to your container registry url
    3. Change to your container registry
    4. Local path of the chart
    5. Your container registry username
    6. Your container registry password

  2. Run the command to synchronize the image.

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

Directly Load with Docker or containerd

Unpack and load the image file.

  1. Unpack the tar compressed file.

    tar xvf mspider.bundle.tar

    After successful unpacking, you will get 3 files:

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

  2. Load the image from local to Docker or containerd.

    docker load -i images.tar

    ctr -n k8s.io image import images.tar

Note

Each node needs to perform the Docker or containerd image loading operation, after loading, you need to tag the image to keep the registry and repository consistent with that used when installing.

Upgrade

Before upgrading, make sure to back up the configuration file of service mesh, which is the --set parameter, to avoid problems caused by configuration loss during the upgrade.

Check if mspider-release repository exists locally

helm repo list | grep mspider-release

If the result is empty or shows as follows, proceed to the next step; otherwise, skip the next step and proceed directly to the update.

Error: no repositories to show

Add Helm Repo

helm repo add mspider-release http://{harbor_url}/chartrepo/{project}

Update the helm repo for the Service Mesh.

helm repo update mspider-release

Choose the version of the Service Mesh you want to install (it is recommended to install the latest version).

# Update the image version in the mspider-release repository
helm update repo

# Get the latest version
helm search repo mspider-release/mspider --versions

NAME                      CHART VERSION  APP VERSION  DESCRIPTION
mspider-release/mspider   v0.20.1        v0.20.1      Mspider management plane application, deployed ...
...

Back up --set Parameters

Before upgrading the Service Mesh version, it is recommended to run the following command to back up the --set parameters of the old version.

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

Update mspider

helm upgrade --install --create-namespace \
    -n mspider-system mspider mspider-release/mspider \
    --cleanup-on-fail \
    --version=v0.20.1 \
    --set global.imageRegistry=release.daocloud.io/mspider \
    -f mspider.yaml

Run helm upgrade

Before upgrading, it is recommended to update the global.imageRegistry field in bak.yaml to the current container registry address.

export imageRegistry={YOUR_IMAGE_REGISTRY}

helm upgrade mspider mspider-release/mspider \
    -n mspider-system \
    -f ./bak.yaml \
    --set global.imageRegistry=$imageRegistry \
    --version 0.20.1
