Description Yunfei Jiang 2021-03-12 09:02:56 UTC

The iam:ListAttachedRolePolicies permission is required for destroying cluster [1], but it's missing in AWS permissions.go file [4].

The official 4.6 and 4.7 documents [2][3] also doesn’t mention the permission requirement .if user configures an AWS account by following the documents, when running `destroy` command, an error will occur and the the IAM role can’t be deleted:

level=warning msg=listing attached IAM role policies: AccessDenied: User: arn:aws:iam::301721915996:user/yunjiang-test-ListAttachedRole is not authorized to perform: iam:ListAttachedRolePolicies on resource: role yunjiang-role48-ffjmv-master-role with an explicit deny arn=arn:aws:iam::301721915996:role/yunjiang-role48-ffjmv-master-role
level=warning msg=    status code: 403, request id: 8d9b8cae-97ed-4c6f-8e8f-4bccfec2fc64 arn=arn:aws:iam::301721915996:role/yunjiang-role48-ffjmv-master-role

Comment 3 Yunfei Jiang 2021-04-08 08:54:07 UTC

Russell, installer will not do permission check when running `destroy cluster`, right?

Comment 4 Matthew Staebler 2021-04-08 13:33:14 UTC

That is correct.

Comment 5 Yunfei Jiang 2021-04-09 08:28:37 UTC

verified. PASS.
OCP version: 4.8.0-0.nightly-2021-04-08-043959


Remove iam:ListAttachedRolePolicies permission from IAM user, and then try to create cluster:

time="2021-04-08T04:45:40-04:00" level=info msg="Credentials loaded from the \"denylistattachedrole\" profile in file \"/home/cloud-user/.aws/credentials\""
...
time="2021-04-08T04:45:45-04:00" level=fatal msg="failed to fetch Cluster: failed to fetch dependency of \"Cluster\": failed to generate asset \"Platform Permissions Check\": validate AWS credentials:     current credentials insufficient for performing cluster installation"
