Application Image Acquisition¶

For installations in an offline network environment, you need to manually download the latest Guance image package first. Afterward, use the docker load command to import all images onto each Kubernetes worker node before proceeding with subsequent installation steps.

When installing launcher, add the imageSecrets.url, imageSecrets.username, and imageSecrets.password parameters.

helm install launcher launcher  --repo https://pubrepo.guance.com/chartrepo/launcher -n launcher \
--create-namespace  \
--set ingress.hostName=<Hostname>,storageClassName=<Stroageclass> \
--set imageSecrets.url=<warehouseaddress>,imageSecrets.username=<warehouse username>,imageSecrets.password=<warehouse passwd>

• Generate a secret

kubectl create secret docker-registry dataflux-test --docker-server='<Repo Server>' --docker-username='<Repo Username>' --docker-password='<Repo Password>'

Replace the values of docker-server, docker-username, and docker-password with your image repository address, account, and password respectively.

• Retrieve the secret

kubectl get secrets dataflux-test -o jsonpath='{.data.\.dockerconfigjson}'

Execution result:

• Installation

Download the Launcher YAML file: https://static.guance.com/launcher/launcher.yaml

Save the content of the YAML file as launcher.yaml on the operations machine, then replace the variable parts within the document:

• Replace {{ launcher_image }} with the latest Launcher application image address, which can be found in the Deployment Image documentation.
• Replace {{ domain }} with the main domain, such as dataflux.cn.
• Replace {{ storageClassName }} with the storage class name, such as alicloud-nas.

Replace the .dockerconfigjson content with the secret obtained earlier.

Execute the installation:

kubectl apply -f launcher.yaml
