Offline Upgrade of Middleware - ElasticSearch Module

This page explains how to install or upgrade the ElasticSearch module of the Middleware after downloading it from the Download Center.

Info

The term mcamel used in the following commands or scripts is the internal development code name for the Middleware module.

Loading Images from Installation Package

You can load the images using one of the following two methods. It is recommended to use chart-syncer to sync the images to your image repository when there is an image repository available, as it is more efficient and convenient.

Syncing Images to Image Repository Using chart-syncer

  1. Create load-image.yaml file.

    Note

    All the parameters in this YAML file are mandatory. You need to have a private image repository and modify the relevant configurations.

    If you have already installed a chart repo in your environment, chart-syncer also supports exporting a chart as a tgz file.

    load-image.yaml
    source:
  intermediateBundlesPath: mcamel-offline # The relative path to where the charts-syncer command will be executed, not the relative path between this YAML file and the offline package
target:
  containerRegistry: 10.16.10.111 # Change it to your image repository URL
  containerRepository: release.daocloud.io/mcamel # Change it to your image repository
  repo:
    kind: HARBOR # It can also be any other supported Helm Chart repository type
    url: http://10.16.10.111/chartrepo/release.daocloud.io # Change it to your chart repo URL
    auth:
      username: "admin" # Your image repository username
      password: "Harbor12345" # Your image repository password
  containers:
    auth:
      username: "admin" # Your image repository username
      password: "Harbor12345" # Your image repository password

    If you haven't installed a chart repo in your environment, chart-syncer also supports exporting a chart as a tgz file and storing it in the specified path.

    load-image.yaml
    source:
  intermediateBundlesPath: mcamel-offline # The relative path to where the charts-syncer command will be executed, not the relative path between this YAML file and the offline package
target:
  containerRegistry: 10.16.10.111 # Change it to your image repository URL
  containerRepository: release.daocloud.io/mcamel # Change it to your image repository
  repo:
    kind: LOCAL
    path: ./local-repo # Local path to the chart
  containers:
    auth:
      username: "admin" # Your image repository username
      password: "Harbor12345" # Your image repository password

  2. Run the command to sync the images.

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

Directly Loading with Docker or containerd

Extract and load the image files.

  1. Extract the tar archive.

    tar -xvf mcamel-elasticsearch_0.10.1_amd64.tar
cd mcamel-elasticsearch_0.10.1_amd64
tar -xvf mcamel-elasticsearch_0.10.1.bundle.tar

    After successful extraction, you will have three files:

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

  2. Load the images from the local directory 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 is complete, tag the images to match the Registry and Repository used during installation.

Upgrade

There are two methods to upgrade. Choose the corresponding upgrade method based on the pre-operation you performed:

  1. Check if the Helm repository exists.

    helm repo list | grep elasticsearch

    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 Helm repository.

    helm repo add mcamel-elasticsearch http://{harbor url}/chartrepo/{project}

  3. Update the Helm repository.

    helm repo update mcamel/mcamel-elasticsearch # If the update fails due to a low helm version, try executing __helm update repo__ instead.

  1. Choose the version you want to install (it is recommended to install the latest version).

    helm search repo mcamel/mcamel-elasticsearch --versions

    [root@master ~]# helm search repo mcamel/mcamel-elasticsearch --versions
NAME                            CHART VERSION   APP VERSION     DESCRIPTION               
mcamel/mcamel-elasticsearch     0.10.1           0.10.1           A Helm chart for Kubernetes
...

  2. Back up the --set parameters.

    Before upgrading to a new version, it is recommended to execute the following command to back up the --set parameters of the old version.

    helm get values mcamel-elasticsearch -n mcamel-system -o yaml > mcamel-elasticsearch.yaml

  3. Run helm upgrade .

    Before upgrading, it is recommended to replace the global.imageRegistry field in mcamel-elasticsearch.yaml with the URL of the image repository you are currently using.

    export imageRegistry={your image repository}

    helm upgrade mcamel-elasticsearch mcamel/mcamel-elasticsearch \
  -n mcamel-system \
  -f ./mcamel-elasticsearch.yaml \
  --set global.imageRegistry=$imageRegistry \
  --version 0.10.1

  1. Back up the --set parameters.

    Before upgrading to a new version, it is recommended to execute the following command to back up the --set parameters of the old version.

    helm get values mcamel-elasticsearch -n mcamel-system -o yaml > mcamel-elasticsearch.yaml

  2. Run helm upgrade .

    Before upgrading, it is recommended to replace the global.imageRegistry field in mcamel-elasticsearch.yaml with the URL of the image repository you are currently using.

    export imageRegistry={your image repository}

    helm upgrade mcamel-elasticsearch . \
  -n mcamel-system \
  -f ./mcamel-elasticsearch.yaml \
  --set global.imageRegistry=${imageRegistry} \
  --set console_image.registry=${imageRegistry} \ 
  --set operator_image.registry=${imageRegistry}
