Offline Upgrade of Middleware - RocketMQ Module¶

This page explains how to install or upgrade the Middleware - RocketMQ 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 for the middleware module.

Loading Images from Installation Package¶

You can load the images in one of the following two ways. When a mirror repository exists in the environment, it is recommended to choose the method of using chart-syncer to synchronize the images to the mirror repository as it is more efficient and convenient.

Synchronize Images to Mirror Repository using chart-syncer¶

Create load-image.yaml .

Note

The parameters in this YAML file are all required. You need to have a private container registry and modify the relevant configurations.

Chart Repo InstalledChart Repo Not Installed

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 # 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 type
    url: http://10.16.10.111/chartrepo/release.daocloud.io # Change it to your 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 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 # 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 to the chart
  containers:
    auth:
      username: "admin" # Your container registry username
      password: "Harbor12345" # Your container registry password

Run the image synchronization command.

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-rocketmq_0.1.0_amd64.tar
cd mcamel-rocketmq_0.1.0_amd64
tar -xvf mcamel-rocketmq_0.1.0.bundle.tar

After successful extraction, you will have three 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

Docker or containerd image loading operation needs to be performed on each node. After loading is complete, you need to tag the image to keep the registry and repository consistent with the installation.

Upgrade¶

There are two ways to upgrade. You can choose the corresponding upgrade method based on the pre-requisite operations:

Upgrade via Helm RepoUpgrade via Chart Package

Check if the helm repository exists.
```
helm repo list | grep rocketmq
```
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-rocketmq http://{harbor url}/chartrepo/{project}

Update the helm repository.

helm repo update mcamel/mcamel-rocketmq # If the Helm version is too low, it may fail. If it fails, try executing __helm update repo__ .

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

helm search repo mcamel/mcamel-rocketmq --versions

[root@master ~]# helm search repo mcamel/mcamel-rocketmq --versions
NAME                            CHART VERSION   APP VERSION     DESCRIPTION               
mcamel/mcamel-rocketmq     0.1.0           0.1.0           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-rocketmq -n mcamel-system -o yaml > mcamel-rocketmq.yaml
```

Run helm upgrade .

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

export imageRegistry={your-registry}

helm upgrade mcamel-rocketmq mcamel/mcamel-rocketmq \
  -n mcamel-system \
  -f ./mcamel-rocketmq.yaml \
  --set global.imageRegistry=$imageRegistry \
  --version 0.1.0

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-rocketmq -n mcamel-system -o yaml > mcamel-rocketmq.yaml
```
