So we have this aws account with some permissions and it was working fine at first. We were able to deploy to aws using serverless framework. But then the client decided to setup an organization since they have other aws accounts also and to consolidate the billing under 1 account, they added the account they gave us to the organization. Now the problem is when we deployed using serverless again, serverless can no longer see the deployment bucket with an access denied error. But when the account was removed from the organization, serverless is able to locate the bucket. Is there some addition permissions or changes to the permissions that needs to be done when an account is linked to an organization? Can someone explain to me cause I can't seem to find any example of my scenario in a google search. I am new to AWS and this is the first time I experience organzations in AWS.
The only implication to permissions from joining an OU (organization unit) would be via the Service Contol Policy (SCP). Verify that the SCP attached to the organization does not block the actions you are attempting to execute.
We would love to get more information if possible, but I would maybe start looking in the following places in your consolidated account:
Trusted access for AWS services - https://console.aws.amazon.com/organizations/home?#/organization/settings
https://console.aws.amazon.com/organizations/home?#/policies
See if anything was changed there, if someone added a policy, or if the AWS Resource Access Manager is disabled.

We have started initially by defining roles with admin access policy attached. But now we want them to have policy with only specific permissions that are minimum and does not create any issues for using these roles.
Looking at "Access Advisor" tab on each role under AWS IAM console, it gives good amount of information that exactly which AWS services getting used and permission level information only for EC2, IAM, Lambda, and S3 management actions services. But for rest of other AWS services, missing that what specific permission for that particular service is required.
Also not having AWS Organizations master account access as mentioned in this tutorial: Viewing last accessed information for Organizations.
So is there a way I can get the permissions level info for services other than EC2, IAM, Lambda, and S3 management actions?
Thanks.

Sadly, there is no such way provided by AWS. So basically its try-and-see approach to get what you want. You can try some third party tools, which may be helpful, such as zero-iam, but ultimately, you will need custom solution to match your requirements.
There is also IAM Access Analyzer which is different then Access Advisor. But its also limited to some services only.
We have two projects in our GCP account; one for our Dev environment and one for our Test environment at the moment. Terraform manages most of our infrastructure, so we have minimal clicking around the GUI, or CLI commands.
I have assumed we enabled the Pub/Sub API by deploying to it with Terraform in both of our environments, although we may have needed to do this manually. We noticed that Google created a default Pub/Sub service account for us in our Dev environment, but not in our Test environment. This docs page suggests it should make this service account.
Additionally, we have noticed multiple Pub/Sub subscriptions working, apparently without any service account. We believe that the service account is only needed for this particular Subscription because it is a push to an e-mail server. Therefore, it needs a service account with the 'Service Account Token Creator' role.
We've attempted to redeploy the whole infrastructure and disable/re-enable the Pub/Sub API. Neither seemed to kick GCP into creating the Service Account. Further to this, we attempted to make the default service account manually. Still, GCP constrains the name a user can give a service account themselves, so we're unable to create a service account with the name that the Pub/Sub service would expect.
We wonder if there is some configuration of the project we may have missed or if anyone has seen this previously?
Does it not exist or does you not see it?
I'm pretty sure that it exists but without any role granted on it and you don't see it in the UI. Try to grant a role on this default service account, and it will appear in the IAM page!
I am having some trouble doing code deploy with my AWS Educate account. Initially, when I was setting things up I was following this article.
https://hackernoon.com/deploy-to-ec2-with-aws-codedeploy-from-bitbucket-pipelines-4f403e96d50c?fbclid=IwAR3rezVMGpuQxTJ3AneOeTL2oMHjCKbQB5C5ouTLhJQ5gRp3JeL4GK0f53o
In it is talks about setting up an IAM service account. The problem is that AWS Educate allows you to create the accounts but it won't generate keys. In order for me to deploy my Spring Boot (and VueJS) apps to my s3 buckets and ec2s from my bitbucket repo, I need a key and secret key and CodeDeploy Group.
Fine I was able to use my Click the Account Details button on the labs.vocareum page and get my keys, however when I am attempting to set up a Code Deploy Group it asks for a service role and I am unsure where to get this?
Why is the service role necessary?
The service role is used by the CodeDeploy service in order to perform actions outside CodeDeploy (i.e. on another service such as S3).
AWS has a special approach of integrating services. Basically, you have to give each service you are using explicit permission to use another service (even if the access stays in the bounds of the same account). There is no inherent permission given to the CodeDeploy service to change things in S3. In fact, CodeDeploy is not even allowed to read files from S3 without explicitly allowing it.
Here is the official explanation from the docs [1]:
In AWS, service roles are used to grant permissions to an AWS service so it can access AWS resources. The policies that you attach to the service role determine which AWS resources the service can access and what it can do with those resources.
What you are actually doing according to the hackernoon article
you need a user account with programmatic access to your aws account
the user account needs to have a policy attached which grants permission to upload files into S3 and trigger a CodeDeploy deployment --> you provide the access key and secret access key of this user to Bitbucket so it can upload the stuff into S3 and trigger a deployment on bahalf of your user identity
Unrelated to steps 1 and 2: Create a role in AWS IAM [2] which will be used by both services (NOT Bitbucket): CodeDeploy and EC2. Strictly speaking, the author of the hackernoon article is merging two steps into one here: You are creating one role which is used by both services (as specified by the two different principals in the trust relationship: ec2.amazonaws.com and codedeploy.us-west-2.amazonaws.com). Usually this is not how IAM policies should be configured because it violates the principle of granting least privilege [4] as the EC2 instances receives permissions from the AWSCodeDeployRole policy which it probably does not need as far as I see. But that is just a philosophical note here. All the steps mentioned in the hackernoon article should technically work.
So, what you actually do is:
granting CodeDeploy permission to perform various actions inside your account, such as viewing which EC2 instances you have started etc. (this is specified inside the policy AWSCodeDeployRole [3])
granting EC2 permission to read the revision which was uploaded to S3 (this is specified inside the policy AmazonS3FullAccess)
To get back to your question...
However when I am attempting to set up a Code Deploy Group it asks for a service role and I am unsure where to get this?
You need to create the service role by yourself inside the IAM service (see [2]). I do not know if this is supported by AWS Educate, but I guess it should be. After creating the service role, you MUST assign it to the CodeDeploy Group (that is the point where you are stuck right now). Moreover, you must assign that same service role to you EC2 instance profile.

We have two AWS account say as Dev and Prod. In Dev account,our code build,code-pipelines and Code-deploy services is configured with S3. However, In Prod account an auto-scaling group is running for the production websites.
As per our requirement, We want to deploy the code from dev account to Prod account with cross-account deployment. Basically, The code-build and code-pipelines will execute the code and by using code-deployment it will deploy in the Prod account's Auto-scaling group.
Can someone give us some insight about to achieve the same.
Thanks
CodePipeline supports cross-account actions, however it's not currently configurable via the console and requires some extra roles to be configured.
Here's a guide on how to make it work: https://docs.aws.amazon.com/codepipeline/latest/userguide/pipelines-create-cross-account.html
As of today, CodeDeploy doesn't support cross-account deployments. Depending on what your goal is, you might be able to achieve it another way.
I want to deploy a bundle in one account to another account
If your S3 bucket allows access to the second account, CodeDeploy doesn't care what account your bundle is in as long as everything can access it. Per #TimB, it looks like CodePipelines can support that behavior.
I need to initiate a deployment in one account to another
If you have a reason why the deployment must be in one account to another, you could set up the instances in the second account to be on-premise instances, though this is not a great solution.
We have multiple AWS accounts (about 15-20), one AWS account per client that we are managing, each account having VPC having dedicated setup of instances. Due to regulatory requirements all accounts needs to be isolated from each other.
What is the best way to manage account credentials for these AWS accounts? Following is what I am thinking
-For any new client
Create a new AWS account
Create AWS IAM roles (admin, developer,
tester) for newly created account using cloudformation
Using master
AWS account, assume roles created in step 2 to access other
accounts.
Is this the right approact to manage multiple accounts?
Thanks in advance.
Facilitating IAM Roles is a very common and (I think) the right approach to manage authentication for multiple accounts indeed, AWS has just recently released resp. updates that greatly help with this, see Cross-Account Access in the AWS Management Console:
Many AWS customers use separate AWS accounts (usually in conjunction with Consolidated Billing) for their development and production resources. This separation allows them to cleanly separate different types of resources and can also provide some security benefits.
Today we are making it easier for you to work productively within a multi-account (or multi-role) AWS environment by making it easy for you to switch roles within the AWS Management Console. You can now sign in to the console as an IAM user or via federated Single Sign-On and then switch the console to manage another account without having to enter (or remember) another user name and password.
Please note that this doesn't just work for the AWS Management Console, but also with the AWS Command Line Interface (AWS CLI), as greatly explored/explained in by Mitch Garnaat in Switching Roles in the AWS Management Console and AWSCLI.
Furthermore, Mitch has followed up with a dedicated new tool 'rolemodel' to help with setting things up pretty much like you outlined, which you might want to evaluate accordingly:
Rolemodel is a command line tool that helps you set up and maintain cross-account IAM roles for the purpose of using them in the new switch role capability of the AWS management console. These same cross-account roles can also be used with the AWSCLI as described here.
