Can you later add new policies to said group without rewriting the old ones?

without answering any of your questions, if you’re going to deal with a lot of policies be mindful of IAM limits (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_iam-limits.html). Some of them are very low. Like, “Managed policies attached to an IAM group: 10”.

Managed policies are the policies that AWS creates right? What about custom policies?

flat-insurance-25294

Are managed policies different than non-managed? I can’t find any info of non-managed policies

Would have been nice to be able to export entire AWS resources in export to use StackReference and get an entire object in a different stack. Like ACM or ECR.

there are two types of policies, managed and inline

orange-australia-91292

managed are the ones you find in the AWS console under “Policies”. it doesn’t matter who manages the policy, you or AWS. that’s managed

orange-australia-91292

inline are policies that you attach directly to the user

orange-australia-91292

inline policies are the “old” type of policy and kind of hidden. there’s a button that you need to click in the UI to get to them. but they can be quite useful due to those limits.

if you check the limits, it says 10 managed per wtv, but inline is limited to the total number of characters instead of number of policies

orange-australia-91292

also, managed policies per role/user can be increased if you ask. per group can’t

flat-insurance-25294

So I supposed inlined policies on groups are basically unlimited ( well limited by characters)

check the last two entries on that page

I’m not sure if it counts spaces or not

flat-insurance-25294

Will have to figure this out later. At this stage, it essentially means max 10 clusters. That’s alright for now.

flat-insurance-25294

Because a Policy can contain multiple statements right? 1 policy doesn’t mean 1 aws resource. 1 policy could mean a collection of ACL on a collection of resources?

flat-insurance-25294

1 policy could be Read S3 Write EKS Read RDS etc

orange-australia-91292

01/03/2020, 11:56 AM

yeap

flat-insurance-25294

01/03/2020, 11:56 AM

Fair enough that should be sufficient for now.

flat-insurance-25294

01/03/2020, 11:56 AM

Thanks a bunch for clearing that up

orange-australia-91292

01/03/2020, 11:56 AM

for managed, you get a limit of 10, but each one can have > 6k characters. that’s a lot. but you have to be mindful of how you combine these things

orange-australia-91292

01/03/2020, 11:57 AM

if you hit these limits at a later stage in development, it can be annoying. speaking from experience

glad to help

We want to spin up resources per branch. So a new pull request would spin up RDS, VPC, EKS, S3, Cloudfront. Create a policy and add them to a group. A developer in said group could then use their rights to check the RDS or create a kubeonfig for the EKS cluster, etc. Will also be creating “users” which are basically our Applications. For creating signed cookies on Cloudfront or upload files to S3.

I don’t want to use InstanceRoles or Roles for those things, rather work with acccess_keys and etc.

flat-insurance-25294

Want to make it as easy as possible for developer to spin up a dev environment. Using a few shared resources (like Route53 and ACM) but mostly isolated.

it is not recommended to use access keys that kind of purposes

white-translator-96007

01/03/2020, 12:00 PM

if you are accessing inside AWS

flat-insurance-25294

01/03/2020, 12:01 PM

What is recommended then?

orange-australia-91292

01/03/2020, 12:01 PM

roles are preferred. also, a user can be part of max. 10 groups
