Usage

RAM Roles for Service Accounts (RRSA)

Enable RRSA feature:

$ ack-ram-tool rrsa enable -c <clusterId>

? Are you sure you want to enable RRSA feature? Yes
Enable RRSA feature for cluster c86fdd*** successfully

Check status of RRSA feature:

$ ack-ram-tool rrsa status -c <clusterId>

RRSA feature:          enabled
OIDC Provider Name:    ack-rrsa-c86fdd***
OIDC Provider Arn:     acs:ram::18***:oidc-provider/ack-rrsa-c86fdd***
OIDC Token Issuer:     https://oidc-ack-***/c86fdd***

Disable RRSA feature:

$ ack-ram-tool rrsa disable -c <clusterId>

? Are you sure you want to disable RRSA feature? Yes
Disable RRSA feature for cluster c86fdd*** successfully

Associate an RAM Role to a service account:

$ ack-ram-tool rrsa associate-role -c <clusterId> -r <roleName> -n <namespace> -s <serviceAccount>

? Are you sure you want to associate RAM Role test-rrsa to service account test-serviceaccount (namespace: test-namespace)? Yes
Will change the assumeRolePolicyDocument of RAM Role test-rrsa with blow content:

  "Statement": [
   {
    "Action": "sts:AssumeRole",
    "Effect": "Allow",
    "Principal": {
     "RAM": [
