Chapter 2. Creating the required Alibaba Cloud resources
Before you install OpenShift Container Platform, you must use the Alibaba Cloud console to create a Resource Access Management (RAM) user that has sufficient permissions to install OpenShift Container Platform into your Alibaba Cloud. This user must also have permissions to create new RAM users. You can also configure and use the ccoctl tool to create new credentials for the OpenShift Container Platform components with the permissions that they require.
Alibaba Cloud on OpenShift Container Platform is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.
2.1. Creating the required RAM user
You must have a Alibaba Cloud Resource Access Management (RAM) user for the installation that has sufficient privileges. You can use the Alibaba Cloud Resource Access Management console to create a new user or modify an existing user. Later, you create credentials in OpenShift Container Platform based on this user’s permissions.
When you configure the RAM user, be sure to consider the following requirements:
The user must have an Alibaba Cloud AccessKey ID and AccessKey secret pair.
-
For a new user, you can select
Open API Accessfor the Access Mode when creating the user. This mode generates the required AccessKey pair. For an existing user, you can add an AccessKey pair or you can obtain the AccessKey pair for that user.
NoteWhen created, the AccessKey secret is displayed only once. You must immediately save the AccessKey pair because the AccessKey pair is required for API calls.
-
For a new user, you can select
Add the AccessKey ID and secret to the
~/.alibabacloud/credentialsfile on your local computer. Alibaba Cloud automatically creates this file when you log in to the console. The Cloud Credential Operator (CCO) utility, ccoutil, uses these credentials when processingCredential Requestobjects.For example:
[default] # Default client type = access_key # Certification type: access_key access_key_id = LTAI5t8cefXKmt # Key 1 access_key_secret = wYx56mszAN4Uunfh # Secret- 1
- Add your AccessKeyID and AccessKeySecret here.
The RAM user must have the
AdministratorAccesspolicy to ensure that the account has sufficient permission to create the OpenShift Container Platform cluster. This policy grants permissions to manage all Alibaba Cloud resources.When you attach the
AdministratorAccesspolicy to a RAM user, you grant that user full access to all Alibaba Cloud services and resources. If you do not want to create a user with full access, create a custom policy with the following actions that you can add to your RAM user for installation. These actions are sufficient to install OpenShift Container Platform.TipYou can copy and paste the following JSON code into the Alibaba Cloud console to create a custom poicy. For information on creating custom policies, see Create a custom policy in the Alibaba Cloud documentation.

2.2. Configuring the Cloud Credential Operator utility
To assign RAM users and policies that provide long-lived RAM AccessKeys (AKs) for each in-cluster component, extract and prepare the Cloud Credential Operator (CCO) utility (ccoctl) binary.
The ccoctl utility is a Linux binary that must run in a Linux environment.
Prerequisites
- You have access to an OpenShift Container Platform account with cluster administrator access.
-
You have installed the OpenShift CLI (
oc).
Procedure
Obtain the OpenShift Container Platform release image by running the following command:
$ RELEASE_IMAGE=$(./openshift-install version | awk '/release image/ {print $3}')Obtain the CCO container image from the OpenShift Container Platform release image by running the following command:
$ CCO_IMAGE=$(oc adm release info --image-for='cloud-credential-operator' $RELEASE_IMAGE -a ~/.pull-secret)
NoteEnsure that the architecture of the
$RELEASE_IMAGEmatches the architecture of the environment in which you will use theccoctltool.Extract the
ccoctlbinary from the CCO container image within the OpenShift Container Platform release image by running the following command:$ oc image extract $CCO_IMAGE --file="/usr/bin/ccoctl" -a ~/.pull-secret
Change the permissions to make
ccoctlexecutable by running the following command:$ chmod 775 ccoctl
Verification
To verify that
ccoctlis ready to use, display the help file by running the following command:$ ccoctl --help
Output of
ccoctl --helpOpenShift credentials provisioning tool Usage: ccoctl [command] Available Commands: alibabacloud Manage credentials objects for alibaba cloud aws Manage credentials objects for AWS cloud gcp Manage credentials objects for Google cloud help Help about any command ibmcloud Manage credentials objects for IBM Cloud nutanix Manage credentials objects for Nutanix Flags: -h, --help help for ccoctl Use "ccoctl [command] --help" for more information about a command.

2.3. Next steps
Install a cluster on Alibaba Cloud infrastructure that is provisioned by the OpenShift Container Platform installation program, by using one of the following methods:
- Installing a cluster quickly on Alibaba Cloud: You can install a cluster quickly by using the default configuration options.
- Installing a customized cluster on Alibaba Cloud: The installation program allows for some customization to be applied at the installation stage. Many other customization options are available post-installation.
