I am member of an organisation account in AWS. I have created two EC2 instance in us-east-1 region. But other team members are not able to see this EC2 instance in Management console.
Since infrastructure or assets is managed by a team and not individuals we need to have a team view for all that is in use. The admin users should have ability to view any instance, that is what we want to achieve here. The problem is at present the user who created the EC2 instance is the only user who is able to see EC2 instance in console.
Below is the account details as it gets displayed in AWS Management Console -
Below is the screen shot which confirms that the user belongs to an organisation -
Can any one suggest how can this be achieved?
If users have the ability to view any instances in the EC2 management console, then they will see all instances in the console.
If they can see some instances (which proves they have the right permission to view instances), but some instances are not appearing then the problem might be one of:
The 'missing' instance was launched in a different account
The 'missing' instance was launched in a different region than you are viewing in the console
There is a filter active on the listing that is limiting the instances shown
You could also try using the AWS Command-Line Interface (CLI) aws ec2 describe-instances command to list instances to verify that the same information is returned for different credentials. (That is, run it as different users and compare the output.)
Bottom line: You should either see them all or see none (due to insufficient permissions to list instances). It is not possible to only view some.

I have 2 EC2 instances spawned using service catalog product provisioning. For some reasons, I have terminated them both and want to spawn new EC2 instances back (Not the terminated ones).
So I tried to update the product again from service catalog and was hoping the service catalog would create them back because the earlier instances are not present.
Product provisioning is successful and yet the EC2 instances are not created.
My product is actually a full stack comprising of some sub-stacks and one of the sub-stack actually creates the EC2 instance.
We could envision this as below -
Full Stack
Sub-Stack-1
Sub-Stack-2
Sub-Stack-3
Question is how to get the new EC2 instances created without having to terminate the full stack.
More info on permission for these -
I have 2 roles that I have used to achieve this. 1 role is used only to provision products from service catalog. Other is admin like role that I can use to terminate the EC2 instance. I just don't want to spawn the EC2's from the admin role and use the products to provision them.
AWS CloudFormation is not "aware" of resources changes made outside of its control. So, it currently thinks that the EC2 instances still exist, even though they have been terminated.
If you have sufficient permissions to use CloudFormation, you could:
Download the CloudFormation template that was deployed by Service Catalog
Remove the section that defines the EC2 instances
Update the stack by providing the edited template -- this will cause CloudFormation to terminate the instances (that are already terminated)
Edit the template and add back the instance definitions, then Update the stack again with this template (effectively the same template that was originally used to launch the stack) -- this should cause new instances to be deployed that match the original specification
I have approximately 40 Windows EC2 instances running at the moment. This number will start to grow substantially in the next few months. Each one is a t2.small Windows 2016 Server instance. Cost is starting to become an issue as the number increases. Each instance has its own Elastic IP address because when user Tom wants to access his machine he will use the DNS tom.mydomain.com.
tom.mydomain.com is registered in a Route53 hosted zone pointing to Elastic IP 22.33.44.55 which has been associated with Tom's EC2 instance.
Problem is that Tom only needs to use his machine 4 hours per day. When not using it he simply shuts the machine down. But... An Elastic IP that is pointing to a stopped instance costs almost as much per hour as a t1.micro instance in a running state.
So what I want to do is when Tom logs into AWS console and starts his EC2 instance, it will automatically register itself with Route53 against the DNS "tom.mydomain.com".
In short I want to do away with the need for Elastic IPs which are fast becoming a very substantial cost.
The tutorial Auto-Register EC2 Instance in AWS Route 53
looks like it does exactly what I want to do. The problem is the scripting is for Linux. I want to get it working for Windows. I have everything done down to step 6 in the tutorial but am stuck there. Any one get something similar to this working on Windows?
I would recommend:
Create a web-based front-end where your users can authenticate and request access to their Amazon EC2 instance
You could use Amazon Cognito for authentication and DynamoDB for data storage
Once the user authenticates, the service can:
Start their EC2 instance (if it was previously stopped)
Associate the random public IP address to the customer's domain name
Tell the user that the instance is now available
Users login to the instance and perform their work function
You then have some mechanism (I'm not sure what) that detects that they no longer need the instance, and then Stops the instance to save costs
The above process avoids assigning IAM credentials to your users. While IAM credentials are important for staff members who work on your AWS infrastructure, they should not be assigned to end-users of your service.
The process also avoids assigning IAM permissions to each EC2 instance. While the instances themselves could call Route 53 to update a record for their domain name, this requires an IAM Role to be assigned to the EC2 instance. If your users have access to the instance itself, this would potentially open a security hole where they could call Route 53 with incorrect data, such as assigning other users' domain names to their own instance.
It's worth mentioning that the above recommendations mirror the way that Amazon WorkSpaces operates — users authenticate, their instance is started and after a period of non-use the instance is stopped.
I will recommend use of cloudformation template. Cloudformation can create EC2 and then attach it to route53 url. So when tom like to use the EC2 instance, he have to run the stack in Cloudformation. Once he finished he have to go back to cloudformation and destroy the stack.
Yes Cloudformation would be a recommended approach. You can try cloudkast which is an online cloudformation template generator. It will make your task of creating cloudformation template very easy and effortless
I try to use one AWS EC2 instance to start another EC2 instance automatically so that it could be started automatically if this monitoring EC2 instance keeps running. I could use SSH to connect to my instance . However ,when I try to use ec2-start-instance . I failed with following bugs:
The instance ID 'i-XXXXXXXX' does not exist
These two instances are in different availability zone so I think it is networking settings problem but I don't know how to solve it.Anyone could help me?
I suspect your answer lies in Roles. i.e. Account A's EC2 instance needs to have a Role Right on Account B to start EC2 instances in Account B. And it needs to somehow be assigned this role. Not sure that's possible?
Check into:
http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-user_externalid.html
"The access policy for the role specifies what the role allows someone to do. For example, you could specify that the role allows someone to manage only your Amazon EC2 and Amazon RDS resources but not your IAM users or groups. In our sample scenario, you use the access policy to give Example Corp read-only access to all of the resources in your account."

I fixed because I used the wrong credentials. One AWS account was set up for my personal website and the other was other uses so I considered using this continuously running instance to do something for me.
Thank you
Is there a way to copy an EC2 snapshop made in one amazon account to another one and i.e. lauch a new instance with it? If it's possible, which steps do I have to do exactly? How to allow another account access to your snapshots and how to copy them across? Would appreciate your help.
This procedure will help you to share your unencrypted snapshots. For security reasons, encrypted snapshots cannot be shared or made public.
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
Click Snapshots in the navigation pane.
The console displays a list of current snapshots and their status.
Select a snapshot and select Modify Snapshot Permissions from the Actions list.
Choose whether to make the snapshot public or to share it with select AWS accounts:
Important
Making your snapshot public shares all snapshot data with everyone. Snapshots with AWS Marketplace product codes cannot be made public.
To make the snapshot public, select Public.
To expose the snapshot only to specific AWS accounts, select Private, enter the ID of the AWS account (without hyphens) in the AWS Account Number field, and click Add Permission. Repeat until you've added all the required AWS accounts.
Click Save when you're done.
Important
When you share a snapshot (whether by sharing it with another AWS account or making it public to all), you are giving others access to all the data on your snapshot. Share snapshots only with people with whom you want to share all your snapshot data.
See here for more : http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-modifying-snapshot-permissions.html
If you want the other account to launch a clone of one of your instances, you can create an AMI from your instance and add the other account ID to the Permissions on the AMI.
The AMI will then appear in their list of "Shared With Me" AMIs and they can launch it.
I'm trying to view an AMI shared from one of my amazon accounts with another amazon account and it's not visible. I've followed all of the instructions here:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/sharingamis-explicit.html
I've been able to share an EBS Volume successfully, but not the AMI. Are there any undocumented issues or steps anyone has run in to which might keep me from viewing the shared AMI?
Alternatively - is there a way to build an AMI from the snapshot?
It's possible that one of your accounts is set to a different region than your other. At least, that's what I just ran into.
AMIs don't cross regions - an AMI created in region A will never show up in any other region. You'll see this if your two accounts are in different regions, or even if you switch regions in one of your accounts.
There are two things you can do:
Just change regions in your target account. The AMI should magically appear - at least, it did for me. Easy, but unsatisfying, if you really like some other region.
In your source account, copy the AMI into the region that you'd like to use it from. Here are the official docs, but it's pretty straightforward. From the console, right-click the AMI, select Copy AMI, choose your region, and press the Copy AMI button. Wait until copied, then set permissions on the newly-generated AMI.
You'll have to wait, but at least you won't have to go through the song-and-dance that you used to.
You need to be in the correct region as well on the left hand side of the filter below launch there is a drop down menu that defaults the AMI's to "Owned by Me". Since you are in the destination account you need to select "Private Images"
All Amazon AWS AMI's are public and visible to all accounts. Are you talking about an AMI that you (or someone else) explicitly created following these steps:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/creating-an-ami.html
If so, the instructions for sharing those are here:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AESDG-chapter-sharingamis.html
(I'm not sure the difference between your link and this link. They seem... the same)
EBS Snapshots, which are not AMIs, can be shared with other accounts. The instructions for sharing EBS Snapshots with other accounts are here:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-modifying-snapshot-permissions.html
I don't know of any direct way to create an AMI from a snapshot. I don't think there is one.
