Application Image Acquisition

Online Deployment Method

Online deployment refers to a Kubernetes environment that can access the public network, so during deployment, Kubernetes can automatically download images from Guance's official public image repository.

To obtain the public address of the Guance image, you can visit Guance Version History.

Offline Deployment Method

Download and Import of Guance Offline Image Packages

Note

If the Kubernetes node host can access the public network, there is no need to import images via the above offline method; the installation program will automatically download the images.

If installing 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 guided installations.

Latest Guance Docker image package download link: https://static.guance.com/dataflux/package/guance-amd64-latest.tar.gz

  1. Use the following command to download the Docker image package locally: 

    $ wget https://static.guance.com/dataflux/package/guance-amd64-latest.tar.gz

  2. After downloading, upload the Docker image package to each Kubernetes node host and execute the following commands to import the Docker image:

  3. Docker Environment Image Import Command: 

    $ gunzip -c guance-amd64-latest.tar.gz | docker load

  4. Containterd Environment Image Import Command: 

    $ gunzip guance-amd64-latest.tar.gz
$ ctr -n=k8s.io images import guance-amd64-latest.tar

Configuration of Self-built Image Repository for Launcher

Note

If the downloaded offline image package is imported into your self-built image repository for use, please make the following configurations.

This operation must be performed before deploying luancher.

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

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

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

Execution result:

  • Installation

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

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

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

Replace the .dockerconfigjson content with the secret.

Execute the installation:

kubectl apply -f launcher.yaml
