7.6. 创建 Operator 角色和策略

在 AWS 集群上部署 Red Hat OpenShift Service 时，您必须创建 Operator IAM 角色。集群 Operator 使用 Operator 角色和策略获取执行集群操作所需的临时权限，如管理后端存储和对集群的外部访问权限。

先决条件

  • 您已完成 Red Hat OpenShift Service on AWS 的 AWS 先决条件。
  • 您已在安装主机上安装和配置了最新的 ROSA CLI (rosa)。
  • 您创建了集群范围的 AWS 角色。

流程

  1. 要创建 Operator 角色，请运行以下命令： 

    $ rosa create operator-roles --hosted-cp --prefix=$OPERATOR_ROLES_PREFIX --oidc-config-id=$OIDC_ID --installer-role-arn arn:aws:iam::$AWS_ACCOUNT_ID:role/${ACCOUNT_ROLES_PREFIX}-HCP-ROSA-Installer-Role
    Copy to Clipboard Toggle word wrap

    以下分类提供了创建 Operator 角色的选项。 

    $ rosa create operator-roles --hosted-cp
	--prefix=$OPERATOR_ROLES_PREFIX
    1 
    
	--oidc-config-id=$OIDC_ID
    2 
    
	--installer-role-arn arn:aws:iam::$AWS_ACCOUNT_ID:role/$ACCOUNT_ROLES_PREFIX-HCP-ROSA-Installer-Role
    3
    Copy to Clipboard Toggle word wrap
    1
    在创建这些 Operator 角色时，您必须提供一个前缀。如果不这样做，则会产生错误。如需有关 Operator 前缀的信息，请参阅本节的额外资源。
    2
    这个值是您为 Red Hat OpenShift Service on AWS 创建的 OIDC 配置 ID。
    3
    这个值是您在创建 Red Hat OpenShift Service on AWS 帐户角色时创建的安装程序角色 ARN。

    您必须包含 -hosted-cp 参数，以便为 Red Hat OpenShift Service on AWS 集群创建正确的角色。此命令返回以下信息：

    输出示例

    ? Role creation mode: auto
? Operator roles prefix: <pre-filled_prefix>
    1 
    
? OIDC Configuration ID: 23soa2bgvpek9kmes9s7os0a39i13qm4 | https://dvbwgdztaeq9o.cloudfront.net/23soa2bgvpek9kmes9s7os0a39i13qm4

? Create hosted control plane operator roles: Yes
W: More than one Installer role found
? Installer role ARN: arn:aws:iam::4540112244:role/<prefix>-HCP-ROSA-Installer-Role
? Permissions boundary ARN (optional):
I: Reusable OIDC Configuration detected. Validating trusted relationships to operator roles:
I: Creating roles using 'arn:aws:iam::4540112244:user/<userName>'
I: Created role '<prefix>-openshift-cluster-csi-drivers-ebs-cloud-credentials' with ARN 'arn:aws:iam::4540112244:role/<prefix>-openshift-cluster-csi-drivers-ebs-cloud-credentials'
I: Created role '<prefix>-openshift-cloud-network-config-controller-cloud-credenti' with ARN 'arn:aws:iam::4540112244:role/<prefix>-openshift-cloud-network-config-controller-cloud-credenti'
I: Created role '<prefix>-kube-system-kube-controller-manager' with ARN 'arn:aws:iam::4540112244:role/<prefix>-kube-system-kube-controller-manager'
I: Created role '<prefix>-kube-system-capa-controller-manager' with ARN 'arn:aws:iam::4540112244:role/<prefix>-kube-system-capa-controller-manager'
I: Created role '<prefix>-kube-system-control-plane-operator' with ARN 'arn:aws:iam::4540112244:role/<prefix>-kube-system-control-plane-operator'
I: Created role '<prefix>-kube-system-kms-provider' with ARN 'arn:aws:iam::4540112244:role/<prefix>-kube-system-kms-provider'
I: Created role '<prefix>-openshift-image-registry-installer-cloud-credentials' with ARN 'arn:aws:iam::4540112244:role/<prefix>-openshift-image-registry-installer-cloud-credentials'
I: Created role '<prefix>-openshift-ingress-operator-cloud-credentials' with ARN 'arn:aws:iam::4540112244:role/<prefix>-openshift-ingress-operator-cloud-credentials'
I: To create a cluster with these roles, run the following command:
	rosa create cluster --sts --oidc-config-id 23soa2bgvpek9kmes9s7os0a39i13qm4 --operator-roles-prefix <prefix> --hosted-cp

    1
    此字段会预先填充您在初始创建命令中设置的前缀。
    2
    此字段要求您选择为 Red Hat OpenShift Service on AWS 集群创建的 OIDC 配置。

    现在，Operator 角色已创建并可用于创建 Red Hat OpenShift Service on AWS 集群。

验证

  • 您可以列出与 Red Hat OpenShift Service on AWS 帐户关联的 Operator 角色。运行以下命令: 

    $ rosa list operator-roles
    Copy to Clipboard Toggle word wrap

    输出示例

    I: Fetching operator roles
