Offline Upgrade Middleware - MinIO Module

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

Info

The term mcamel appearing in the following commands or scripts refers to the internal development code name of the middleware module.

Load Images from Installation Package

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

Synchronize Images to Image Repository using chart-syncer

  1. Create load-image.yaml .

    Note

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

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

    load-image.yaml
    source:
  intermediateBundlesPath: mcamel-offline # Relative path to the charts-syncer command execution, not relative to this YAML file and the offline package
target:
  containerRegistry: 10.16.10.111 # Replace with your image repository URL
  containerRepository: release.daocloud.io/mcamel # Replace with your image repository
  repo:
    kind: HARBOR # It can be any other supported Helm Chart repository type
    url: http://10.16.10.111/chartrepo/release.daocloud.io # Replace with 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 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 the specified path.

    load-image.yaml
    source:
  intermediateBundlesPath: mcamel-offline # Relative path to the charts-syncer command execution, not relative to this YAML file and the offline package
target:
  containerRegistry: 10.16.10.111 # Replace with your image repository URL
  containerRepository: release.daocloud.io/mcamel # Replace with 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 synchronize images.

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

Load directly using Docker or containerd

Unpack and load the image files.

  1. Unpack the tar archive.

    tar -xvf mcamel-minio_0.8.1_amd64.tar
cd mcamel-minio_0.8.1_amd64
tar -xvf mcamel-minio_0.8.1.bundle.tar

    After successful extraction, you will get three files:

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

  2. Load the images from the local directory into 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 keep the Registry and Repository consistent with the installation.

Upgrade

There are two ways to upgrade. Choose the corresponding upgrade method based on the preconditions:

  1. Check if the helm repo exists.

    helm repo list | grep minio

    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 repo.

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

  3. Update the helm repo.

    helm repo update mcamel/mcamel-minio # If helm version is too low and the update fails, try running helm update repo

  4. Select the version you want to install (we recommend installing the latest version).

    helm search repo mcamel/mcamel-minio --versions

    [root@master ~]# helm search repo mcamel/mcamel-minio --versions
NAME                            CHART VERSION   APP VERSION     DESCRIPTION               
mcamel/mcamel-minio     0.8.1           0.8.1           A Helm chart for Kubernetes
...

  5. Back up the --set parameters.

    Before upgrading the version, we recommend executing the following command to back up the --set parameters of the previous version.

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

  6. Run helm upgrade .

    Before upgrading, it is recommended to update the global.imageRegistry field in mcamel-minio.yaml to the address of the image repository currently in use.

    export imageRegistry={your image repository}

    helm upgrade mcamel-minio mcamel/mcamel-minio \
  -n mcamel-system \
  -f ./mcamel-minio.yaml \
  --set global.imageRegistry=$imageRegistry \
  --version 0.8.1

  1. Back up the --set parameters.

    Before upgrading the version, we recommend executing the following command to back up the --set parameters of the previous version.

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

  2. Run helm upgrade .

    Before upgrading, it is recommended to update the bak.yaml file's global.imageRegistry field to the address of the image repository currently in use.

    export imageRegistry={your image repository}

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