When you use Container Service for Kubernetes (ACK) for the first time, you must assign the default roles to ACK with your Alibaba Cloud account. Only after you assign these roles, ACK can use resources in other cloud services to create clusters or save log files. These cloud services include Elastic Compute Service (ECS), Object Storage Service (OSS), Apsara File Storage NAS (NAS), and Server Load Balancer (SLB). This topic describes how to assign the default roles to ACK and activate the associated cloud services when you use ACK for the first time.
Step 1: Activate ACK
ACK is available for commercial use. You must activate ACK before you can create an ACK cluster. Perform the following steps to activate ACK:
- Go to the Container Service for Kubernetes page.
- Read and select Container Service for Kubernetes Terms of Service.
- Click Activate Now.
Note If you have not activated ACK before, you are prompted to activate ACK in the Dependency Check section of the cluster creation page when you create an ACK cluster.
Step 2: Assign the default roles
When you use ACK for the first time, you must assign the default roles to ACK with your Alibaba Cloud account. Perform the following steps to assign the default roles:
Note Both Alibaba Cloud accounts and Resource Access Management (RAM) users can assign
default roles to ACK. However, the RAM users must belong to your Alibaba Cloud account
and are authorized to manage ACK.
- Log on to the ACK console.
- Click Go to RAM console to navigate to the Cloud Resource Access Authorization page. Then, click Confirm Authorization Policy.
- After you assign the default roles to ACK, log on to the ACK console again to get started with ACK.
Step 3: Activate the associated cloud services
Some features provided by ACK are reliant on or associated with other cloud services.
Therefore, you must activate the cloud services before you can use these features.
Note You must use your Alibaba Cloud account to activate these cloud services. RAM users
are not allowed to activate cloud services.
Log on to the Alibaba Cloud official website with your Alibaba Cloud account and activate
the following cloud services based on your requirements.
- Required: the services that you must activate. These services must be activated so that ACK clusters can function as normal.
- Recommended: the services that we recommend you to activate. You can choose to use these services when you create ACK clusters and manage applications.
- Optional: the services that you can activate based on the architecture and O&M strategy.
