AWS Assume IAM Role - Step by Step tutorial (Part-3)

🎥 In this tutorial, we dive deep into AWS Identity and Access Management (IAM) to understand how to assume roles and grant temporary permissions to users.
🔵 What You'll Learn:
1. Create a Generic IAM Role: Start off by understanding the basics of IAM roles and how to create a generic role.
2. Create IAM User & Assume Role: Dive deeper as we create an IAM user and grant this user permissions to assume a role.
3. Create IAM Policy & Attach to the User: Conclude by crafting a specific IAM policy and attaching it to the user, defining the precise permissions they have when assuming the role.
🔵 Why is this Important?
Assuming roles in AWS is crucial for temporary access, cross-account access, and ensuring that your AWS infrastructure maintains a high standard of security. Mastering this concept is a must for those who aim to manage and administer AWS resources effectively.

This was a great tutorial. I now understand how to assume roles better. Thank you

You're very welcome!

this is best explanation to create assume roles

perfect tutorial for assume role...thanks!!!

[@anild-fh4tb]

Thank you Rahul! Great content! It really helped me a lot, I have gone through your Terraform videos also. I wish you good luck and keep educating us.

[@RahulWagh]

Glad it helped

[@mihirsuratwala9563]

Thanks for such nice video, also when we create a Iam role. In that we can edit the trust relationship and add multiple user's arn in list. Which will be more easy to give the assume role permission to multiple users at once.

Awesome.... was searching this content. Thank You

Glad it was helpful!

[@RajashekarReddydasari]

What is the difference? Normally you would attach policies in the iam user and now you are saying assumerole. How is this beneficial? People keep saying temporary credentials but no proper example. Take a usecase like onprem Jenkins deploying code to ec2 instance or webapi calling lambda.

[@AdarshKumar-dk6sk]

Role is for the service and policy is for the user

Excellent explanation, though I am a bit confused, rather might I say, trying to understand what would be the best case, real time scenario where STS: Assume Role can be implemented?

Role is a container for a set of policies, and can be thought of as a phantom user. When you assumeRole, you become that phantom user to gain access to several different policies at once.

[@user-kz7hq7lt9s]

Why to use that sign in link of the IAM role again after we created a inline-policy for the IAM user(test-user) where we have given the action to assume the IAM role(S3-Full-access-role). what's the significance of inline-policy then?

[@user-zo7up3bz4r]

Hey Rahul, For a small organization setup, no need to have 2 separate policies (resource policy & Trust Policy) We can give resource ARN (of who needs to assume this role) in the role trust relationship tab itself like below. Please share your comments.. In your video though & by default, Principal is AWS account. { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::XXX:user/test-user" }, "Action": "sts:AssumeRole", "Condition": {} } ] }

very informative

[@RahulWagh]

You are welcome

[@krishm5116]

Thanks. 1) Roles can have Policies but here Policy was referring Roles (role arn). 2) To achieve this need, user-id can be directly added S3-Full-Access policy also right?

[@SuperSrikanth2012]

can we attache policy directly to IMA User without role

Sir, What is the difference between root user and management account?

[@pedrocarbon]

I was invited to entry a organization company in AWS, create my account, accept the invitation. But when i log in i dont see any service of the organization, just of my own account. How can i switch to see the services of the company?

[@shivaprasadvadde6503]

I think still you don't have any permissions to access

[@ritupradhan6922]

Why we need aws role if we already have IAM policies.... root account can attache s3 policy for test user or if the test user is the root user than it have already all access....

[@RahulWagh]

Yes you are right but here I am trying to explain the assume by simulating the root user, test user and IAM roles otherwise how would explain the assume role scenario. I could easily solve the whole scenario by assigning correct IAM role to test user but that is not the case

[@ventin75]

It will be great if you can add in how to perform these in the CLI.

[@RahulWagh]

But why do not you use the Terraform so that you have infrastructure as a code

[@ventin75]

@@RahulWagh All the infra is already provisioned except the instance. So I just need a simple CLI command to run the instance.

[@sithembisongiba5048]

😢help here, root user can't create user because no identity based policy

[@user-mb1xr3zu3b]

Sir a doubt, that means roles can be assumed for a single time or upto a time limit but policies will be permanent? Is my understanding right ?

[@RahulWagh]

Roles can be assumed when ever we need there is no time limit

[@user-mb1xr3zu3b]

@@RahulWagh sir then if we are creating policies and using them directly to our users and services why there is a need of roles ? Please differentiate and help me understand

[@bantamalebronejames9588]

Rahul, please what is the difference between this and the Part 1 video. For me it looks the same, but this one is a long process

[@RahulWagh]

Part 1 is only focused on creating IAm role and user. But this part is more focused on how to assume the IAM role. Both the parts will look same in the beginning but there is big difference when you reach towards the end.

[@bantamalebronejames9588]

Alright, thank you@@RahulWagh

I ain't able to switch accounts in the test account.. "Invalid information in one or more fields Check your information or contact your administrator." This is what it threw..can you help me out?

[@RajeeshCr2006]

Try this policy at Roles trust relationship tab instead of giving policy at user end { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::XXX:user/test-user" }, "Action": "sts:AssumeRole", "Condition": {} } ] }

[@anilrout9388]

nice once can you create s3 cross region with 2 account

[@RahulWagh]

I will try

[@mangeshkhandale6435]

Content is good but the example given here is slightly confusing. In this example, you have created a user which inline policy calls the role. It is policy attached to the Role where the actual instructions are given to grant the access to the S3. Although this has worked but it is complex use. On the other hand the same can be achieved without uaing Role also. Here is how: Go to user & inline policy in it. In this policy you mark "Effect: Allow" , "Action:s3.*", "Resource:*" Thats it. Your user can now able to access the S3. No need to assume any Role or switch the URL etc.

[@mangeshkhandale6435]

Above is the example of inline policy. You can also attach the AWS managed policy. E.g. in the same example above, when click on add permissions select "Add permissions" instead of "Create inline policy" Select radio button "Attach policy directly". A list of policies appears. Select "AmazonS3FullAccess" from the list and save it. That's it. Your test user can now access the S3 services

[@RahulWagh]

@mangeshkhandale6435 I think you are confused i am not solving the problem on accessing the s3 bucket but instead how to access s3 bucket owned by the other account via assume role. Otherwise why would aws have the concept of assume role

[@mangeshkhandale6435]

Yes. I got it. What I was trying to say is , technically both approaches work. I'm not able to understand what is the benifit of assuming roles by IAM user. In the example you given I don't see any benifit. But definitely there must be some use cases. I'm not a pro in AWS. But I can see from vedios you have good knowledge here. May be you can create a vedio on use case where IAM user assume role instead of permissions from inline policies.
