In 
@Pulumi/aws
I've created a Role and a Policy, and used both RolePolicyAttachment and also PolicyAttachment, but have no luck in attaching a policy to the role. What's the way to attach policies to roles?
m
RolePolicyAttachment
is the way to do this. What sort of problem are you seeing?
e
The policies aren't getting attached
e.g. "Permissions Policies" is empty when I look at the role in the console.
Copy code
const clusterRole = new aws.iam.Role(config.require("group")+"-k8s-cluster-role", {
  assumeRolePolicy: JSON.stringify({
    Version: "2012-10-17",
    Statement: [{
      Action: "sts:AssumeRole",
      Principal: {
        AWS: "arn:aws:iam::"+config.require("accountId")+":root"
      },
      Effect: "Allow"
    }]
  })
});
const eksClusterRolePolicyAttachment = new aws.iam.RolePolicyAttachment("eks-cluster-policy-attachment", {
    role: clusterRole,
    policyArn: eksPolicy.arn
});
const ecrReadClusterRolePolicyAttachment = new aws.iam.RolePolicyAttachment("ecr-read-cluster-policy-attachment", {
    role: clusterRole,
    policyArn: ecrReadPolicy.arn
});
const s3ReadRolePolicyAttachment = new aws.iam.RolePolicyAttachment("s3-read-cluster-policy-attachment", {
    role: clusterRole,
    policyArn: s3ReadPolicy.arn
});
Those policies are created and I can see them via the console, but they're not listed as attached to the 
clusterRole
m
are these policies attached to any other roles?
e
not yet
but they will be
m
kk
e
Am I supposed to use 
RolePolicy
or 
Policy
?
m
RolePolicy
, I think
e
I want to attach a policy to a role and to a group
Do I need duplicate policies? One for 
RolePolicy
and one 
Policy
?
m
you might need two, yes
I'm honestly not 100% sure. I haven't used group policies before.

okay, I'll explore a bit on it
I got things working, except for this:
Copy code
// Dev Assume Role Policy to use the cluster role for accessing kubernetes clusters
const devAssumeRolePolicy = new aws.iam.Policy(groupName+"-assumerole-read-policy", {
  policy: JSON.stringify({
    Version: "2012-10-17",
    Statement: [
      {
        Effect: "Allow",
        Action: [
          "sts:AssumeRole"
        ],
        Resource: [
          clusterRole.arn
        ]
      },
      {
        Effect: "Allow",
        Action: "sts:GetCallerIdentity",
        Resource: "*"
      }
    ]
  })
});
const devAssumeRoleReadPolicyAttachment = new aws.iam.PolicyAttachment(groupName+"-assumeRole-policy-attachment", {
  groups: [group],
  policyArn: devAssumeRolePolicy.arn
});
When I code in a specific string for the clusterRole.arn then it works, but when I use 
clusterRole.arn
then there's a big problem

how do I get a string version of the clusterRole's ARN?
b
@stocky-spoon-28903 Should also be able to help with a lot of this.
e
I found out that the clusterRole was not populated by the time the Policy was read, so I did a 
clusterRole.apply({ ... });
to make sure the ordering happens correctly. Is there a more Pulumi-ish way to set up ordering/dependency? Follow-up, why isn't the dependency ordering honored for the clusterRole when I need to use the 
clusterRole.arn
in a policy?
s
I’m on the move at the moment, will comment here shortly though
e
Is there a 
dependsOn
I can add to enforce it?
o
@early-musician-41645 @stocky-spoon-28903 any update on this? I think this is the issue I'm having too
did you have to go the apply route? I keep getting invalid policy doc
`function createK8sDelegation() { const awsCaller = aws.getCallerIdentity(); awsCaller.then(root => { const assumeRootRolePolicy = <aws.iam.PolicyDocument>{ Version: "2012-10-17", Statement: [ { Effect: "Allow", Principal: { AWS: 
arn:aws:iam::${root.accountId}:root
}, Action: "sts:AssumeRole" } ] }; // Create an IAM role for K8s namespace access const k8sDevPolicies = { eksViewer: aws.iam.ReadOnlyAccess }; const k8sNamespaceAdminRole = newRoleWithPolicies( "k8sDevNSAdminRole", { description: "k8s namespace admin role for groups", assumeRolePolicy: assumeRootRolePolicy }, k8sDevPolicies ); const k8sdevpolicy = new aws.iam.Policy( "k8s-dev-namespace-policy", { description: "Policy that allow you to do K8s stuff", policy: JSON.stringify({ Version: "2012-10-17", Statement: [ { Effect: "Allow", Resource: 
${k8sNamespaceAdminRole.arn}
, Action: ["sts:AssumeRole"] } ] }) }, { parent: k8sNamespaceAdminRole } ); new aws.iam.GroupPolicyAttachment("k8s-ns-to-dev-group-attachment", { group: k8sNamespaceAdminGroup, policyArn: k8sdevpolicy.arn }); return assumeRootRolePolicy; }); }`
it doesn't like the role.arn
e
@orange-tailor-85423 I ended up with this and it works:
Copy code
215 clusterRole.arn.apply(arn => {
216   // Dev Assume Role Policy to use the cluster role for accessing kubernetes clusters
217   // Doing this in a .apply() block because of an ordering issue with Pulumi and getting the clusterRole.arn
218   const devAssumeRolePolicy = new aws.iam.Policy(groupName+"-assumerole-read-policy", {
219     policy: JSON.stringify({
220       Version: "2012-10-17",
221       Statement: [
222         {
223           Effect: "Allow",
224           Action: [
225             "sts:AssumeRole"
226           ],
227           Resource: [
228             arn
229           ]
230         }
231       ]
232     })
233   });
234   const devAssumeRoleReadPolicyAttachment = new aws.iam.PolicyAttachment(groupName+"-assumeRole-policy-attachment", {
235     groups: [group],
236     policyArn: devAssumeRolePolicy.arn
237   });
238 });
