Container Service for Kubernetes (ACK) only supports single-cluster component management, which requires you to manually maintain component versions in each cluster. This increases maintenance costs and can lead to stability issues during component upgrades. Distributed Cloud Container Platform for Kubernetes (ACK One) Fleet provides cluster administrators with unified and automated component management capabilities. ACK One Fleet allows you to define a baseline that includes multiple components and their versions, and deploy it across multiple clusters. It also supports features such as component configuration, batch deployment, and rollback, which enhance system stability. This topic describes how to install and manage components in a multi-cluster scenario.
Prerequisites
The Fleet management feature is enabled.
Multiple clusters are associated with the Fleet instance.
Create a component baseline
Log on to the ACK One console. In the left-side navigation pane, choose .
Click the Add-on Baselines tab, click Create Add-on Baseline, and complete the creation according to the page prompts.
Parameter
Description
Modifiable after creation
Cluster Type
Select a value based on the cluster types associated with the Fleet instance. Different clusters may require different components.
Baseline Name
The name of the custom baseline.
Add-on Tags
Select and add components and versions based on the component types.
After the configuration is complete, click OK. You can view the created baseline name and corresponding component versions on the Add-on Baselines page, and you can also edit the component baseline.
You can click the Baseline Name to view the deployment status of each component in each cluster of the Fleet.
NoteAfter the baseline is deployed, all components in the selected cluster will be installed with the baseline version, except for components that already have higher versions installed.
Create a deployment task
On the Deployment Tasks tab, click Create Deployment Task, and complete the configuration according to the page prompts.
Parameter
Description
Select Baseline
Select the component baseline you want to execute from the created component baselines.
Select Cluster
Select the clusters on which you want to execute the component installation task.
Deployment Settings
Non-batched
The selected clusters will be deployed one by one from small to large scale.
Custom Batch
Batches
You can deploy components in batches across clusters.
Auto Execute
If you do not enable Auto Execute, you must manually click Start in the Deployment Details panel after the deployment task is created.
If you enable Auto Execute, you can configure the Batch Interval parameter, and the deployment task will execute automatically after creation.
Select batch 1 for deployment
If you select clusters or modify the number of batches, the selected deployment clusters below will be cleared. Proceed with caution.
Deploy components in batches based on the clusters you selected.
After the configuration is complete, click Next to view the detailed deployment information. On this page, you can customize the parameters for components in each cluster. After the configuration is complete, click Confirm.
Log on to the ACK One console. In the left-side navigation pane, choose .
View the results
Log on to the ACK One console. In the left-side navigation pane, choose .
Click the Deployment Tasks tab, find the deployment task that you want to manage, and click Details in the Actions column.
(Optional) If the deployed components do not meet your expectations, you can click Roll Back. After confirmation, click Confirm Rollback to roll back the components.
