Identity and access management in App2Container

Your AWS security credentials identify you to AWS and grant you access to your AWS resources. For example, they can allow you to access artifacts saved to an Amazon S3 bucket. You can use features of AWS Identity and Access Management (IAM) to allow other users, services, and applications to use specific resources in your AWS account without sharing your security credentials. You can choose to allow full use or limited use of your AWS resources.

If you are the owner of the AWS account and use AWS as the root user, we strongly recommend that you create an IAM admin user to use for access to your AWS resources. See Creating Your First IAM Admin User and Group in the IAM User Guide to set up your own access before setting up any other IAM users who need to use App2Container.

By default, IAM users don't have permission to create or modify resources. To allow IAM users to create or modify resources and perform tasks, you must create IAM policies that grant permission to use the specific resources and API actions that they need. For more information about IAM policies, see Policies and Permissions in the IAM User Guide.

IAM groups and roles are a flexible way to manage permissions across multiple users. When you assign a user to a group or when your user assumes a role, that user inherits the group's or role's permissions, and is allowed or denied permission to perform the specified tasks on the specified resources. You can assign multiple users to the same group, and a role can be assumed by authorized users. While groups and roles both serve the purpose of granting access to resources, roles are more task-oriented, and assuming a role provides you with temporary security credentials for your role session.

IAM security best practices

Follow these top four security best practices when setting up your IAM resources. For more information and additional best practices, see Security Best Practices in IAM in the IAM User Guide.

Lock away your AWS account root user access keys

Protect your root user access key like you would your credit card numbers or any other sensitive secret, and only use your root user account for necessary account and service management tasks.
Create individual IAM users

Don't use your AWS account root user credentials to access AWS, and don't give your credentials to anyone else. Instead, create individual users for anyone who needs access to your AWS account.
Use groups or roles to assign permissions to IAM Users

Instead of defining permissions for individual IAM users, it's usually more convenient to create groups that relate to job functions (administrators, developers, accounting, etc.) or roles that relate to specific tasks.
Grant least privilege

When you create IAM policies, follow the standard security advice of granting least privilege, or granting only the permissions required to perform a task. Determine what users (and roles) need to do and then craft policies that allow them to perform only those tasks.

We recommend that you create a general purpose IAM group that can run all of the commands except commands that are run with the --deploy option.

If you plan to use App2Container to deploy your containers or create pipelines, then you should create a separate IAM user for deployments. The deployment user needs to be able to create or update AWS objects for container management services (Amazon ECR, Amazon ECS, Amazon EKS, and App Runner), and to create pipelines with AWS CodeStar services. This requires elevated permissions that should only be used for deployment.

Create IAM resources for general use

Follow best practices by using the following steps to create an IAM group with access to perform specific tasks, using specific resources, and to assign users to the group.

Note

Alternatively, you can create an IAM role and EC2 instance profile to grant permissions to applications that run on an Amazon EC2 instance. For more information about using instance profiles, see Using an IAM role to grant permissions to applications running on Amazon EC2 instances in the IAM User Guide.

Create a customer managed IAM policy

You can create a customer managed IAM policy for your general purpose user or group, using one of the example policies on this page after you have customized the JSON to refer to your resources. To create a policy using the AWS console, see Creating policies on the JSON tab in the IAM User Guide. To create a policy using the AWS CLI, use the create-policy command.

Tip
Review your policy periodically, to add actions required for newer features, and to ensure that the policy continues to meet your needs.
Create IAM users and a group

Every user who will run app2container commands needs to have an IAM user created for accessing AWS resources under your account. To follow best practices, you can create an IAM group with the policy attached, and assign users to it.

To create an IAM user, see Creating an IAM User in Your AWS Account in the IAM User Guide. Be sure to select programmatic access to AWS when you create the IAM user.

Perform the following steps to create an IAM group and assign users to it.
1. To create an IAM group, see Creating IAM Groups in the IAM User Guide.
2. Ensure that every person who will run app2container commands has an IAM user defined for AWS access.
3. To assign the users to the group that you created in step 1a, see Adding Permissions to a User (Console), or Adding and Removing a User's Permissions (AWS CLI or AWS API) in the IAM User Guide.
Save your AWS access keys

Save the access keys for your new or existing IAM user in a safe place. You'll need them to configure your AWS profile as part of getting set up for App2Container.
Attach or assign the policy

Use one of the following methods to assign permissions to your IAM users.
- Attach the policy to the IAM group
  
  Attach the policy that you created in step 1 to the group that you created in step 2. See Attaching a Policy to an IAM Group in the IAM User Guide.
- Embed the policy inline for an IAM user
  
  Embed the policy that you created in step 1 inline for your IAM user. See the section that begins with "To embed an inline policy" in Adding Permissions to a User (Console), or Adding and Removing a User's Permissions (AWS CLI or AWS API) in the IAM User Guide.

Example IAM policies

You can use one of the policy templates in this section as a starting point to configure the access that App2Container uses on your behalf to generate the deployment artifacts for your application containers.

Choose the policy resources and actions that you need

The following sections in the example policies depend on choices you've made for your containerization environment and workflow:

AWS CodeCommit

SectionForCodeCommitAccess – If you use App2Container to generate a container pipeline, you must grant access to interact with your CodeCommit code repository.
FireLens log routing to Amazon Data Firehose

SectionForFirelensFirehoseIAMPolicyAccess, SectionForFirelensFirehoseIAMRoleAccess, and SectionForFirelensFirehoseStreamsAccess – If you use FireLens for log file routing, and you configure FireLens to route to Firehose, you must grant access for App2Container to create a new Firehose delivery stream. You must also grant access for App2Container to create an IAM policy and role so that FireLens can access the delivery stream.
FireLens log routing to Amazon Kinesis Data Streams

SectionForFirelensKinesisStreamsAccess – if you use FireLens for log file routing, and you configure FireLens to route to Kinesis Data Streams you must grant access for App2Container to create a new Kinesis data stream.
AWS Secrets Manager

SectionForSecretManagerAccess – If you configured your environment to run remote workflows, App2Container requires you to use Secrets Manager for connection secrets to access application servers from the worker machine. You must grant access to retrieve secrets in the policy.
Amazon S3

SectionForS3Access and SectionForS3ReadAccess – If you set up an S3 bucket for application or deployment artifacts, you must grant access to your bucket in the policy.

You must also ensure that only authorized users can access the bucket. We recommend that you use server-side encryption for your bucket. See Protecting data using server-side encryption in the Amazon Simple Storage Service User Guide for more information about how to set it up.
Upload support bundle

SectionForUploadSupportBundleService – If you chose to have App2Container logs and command-generated artifacts uploaded automatically for failed commands when you ran the init command, you must grant access to upload the application support bundles.
Usage metrics

SectionForMetricsService – If you gave consent for App2Container to collect and export application usage metrics when you ran the init command, you must grant access to upload the metric data.
Amazon VPC

SectionForByoVPC – If you specify your own VPC or want to reuse an existing VPC that App2Container created for a prior deployment, you must grant access to associated describe actions in the policy.

Other policy sections in the examples are required for App2Container to generate application deployment artifacts, or to integrate with Jenkins pipelines.

Create IAM resources for deployment

The AdministratorAccess policy grants an IAM user full access to AWS. Therefore, IAM users with this policy can deploy a containerized application using any of the AWS services for deployment that are supported by App2Container.

Create an IAM user

You can create an IAM user with full access to AWS API actions and resources. Be sure to grant the user programmatic access to AWS and to attach the AdministratorAccess policy. For more information, see Creating IAM users in the IAM User Guide.
Save your AWS access keys

Save the access keys for the IAM user in a safe place. You'll need them to configure your AWS profile as part of getting set up for App2Container.
