Offline Upgrade Middleware - RabbitMQ Module¶

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

Info

The term mcamel mentioned in the following commands or scripts is the internal development code name of the middleware module.

Load Images from Installation Package¶

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

Synchronize Images to Container Registry Using chart-syncer¶

Create load-image.yaml .

Note

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

Installed Chart RepoNot Installed Chart Repo

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

load-image.yaml

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

If the current environment has not installed a chart repo, 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 # This is the relative path to execute the charts-syncer command, not the relative path between this YAML file and the offline package.
target:
  containerRegistry: 10.16.10.111 # Change it to your container registry URL
  containerRepository: release.daocloud.io/mcamel # Change it to your container registry
  repo:
    kind: LOCAL
    path: ./local-repo # Local path of the chart
  containers:
    auth:
      username: "admin" # Your container registry username
      password: "Harbor12345" # Your container registry password

Run the command to synchronize images.

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

Load Directly from Docker or containerd¶

Unpack and load the image files.

Extract the tar archive.

tar -xvf mcamel-rabbitmq_0.13.1_amd64.tar
cd mcamel-rabbitmq_0.13.1_amd64
tar -xvf mcamel-rabbitmq_0.13.1.bundle.tar

After successful extraction, you will have 3 files:

hints.yaml
images.tar
original-chart

Load the images from the local directory to Docker or containerd.
Dockercontainerd
docker load -i images.tar
ctr -n k8s.io image import images.tar

Note

Each node needs to perform Docker or containerd image loading operations. After loading is complete, tag the images to keep the Registry and Repository consistent with the installation.

Upgrade¶

There are two ways to upgrade. You can choose the corresponding upgrade method according to the pre-operation:

Upgrade via helm repoUpgrade via chart package

Check if the helm repository exists.
```
helm repo list | grep rabbitmq
```
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
```

Add the helm repository.

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

Update the helm repository.

helm repo update mcamel/mcamel-rabbitmq # If the helm version is too old, it may fail. In that case, try executing __helm update repo__ .

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

helm search repo mcamel/mcamel-rabbitmq --versions

[root@master ~]# helm search repo mcamel/mcamel-rabbitmq --versions
NAME                            CHART VERSION   APP VERSION     DESCRIPTION               
mcamel/mcamel-rabbitmq     0.13.1           0.13.1           A Helm chart for Kubernetes
...

Back up the --set parameters.

Before upgrading the version, it is recommended to execute the following command to back up the --set parameters of the old version.
```
helm get values mcamel-rabbitmq -n mcamel-system -o yaml > mcamel-rabbitmq.yaml
```

Run helm upgrade .

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

export imageRegistry={your-registry}

helm upgrade mcamel-rabbitmq mcamel/mcamel-rabbitmq \
  -n mcamel-system \
  -f ./mcamel-rabbitmq.yaml \
  --set global.imageRegistry=$imageRegistry \
  --version 0.13.1

Back up the --set parameters.

Before upgrading the version, it is recommended to execute the following command to back up the --set parameters of the old version.
```
helm get values mcamel-rabbitmq -n mcamel-system -o yaml > mcamel-rabbitmq.yaml
```
