CodeCommit

• a version control service hosted by Amazon Web Services
  • tracks and manages code changes
  • Maintains version history
• Centralized Code Repository
  • use to privately store and manage assets (such as documents, source code, and binary files) in the cloud.
  • place to store source code, binaries, libraries, images, HTML files …
  • based on Git
• Enables Collaboration
  • manages updates from multiple users.

---

basic

• secure, highly scalable, managed source control service that hosts private Git repositories.
• eliminates the need to manage your own source control system or scaling the infrastructure.
• use CodeCommit to store anything from code to binaries.
• It supports the standard functionality of Git, works seamlessly with your existing Git-based tools.

With CodeCommit, you can:

1. fully managed service

   hosted by AWS.

   • high service availability and durability and eliminates the administrative overhead of managing your own hardware and software.
   • no hardware to provision and scale and no server software to install, configure, and update.
2. Store code securely
   • Encryption
     • CodeCommit repositories are auto encrypted at rest and in transit through AWS Key Management Service (AWS KMS) using customer-specific keys.
     • You can transfer your files to and from AWS CodeCommit using HTTPS or SSH, as you prefer.
   • Access Control
     • AWS CodeCommit uses AWS Identity and Access Management to control and monitor who can access the data and how, when, and where they can access it.
     • CodeCommit also helps you monitor your repositories via AWS CloudTrail and AWS CloudWatch.
3. Work collaboratively on code
   • CodeCommit repositories support pull requests
     • provide a mechanism to request code reviews and discuss code with collaborators.
   • users can review and comment on each other’s code changes before merging them to branches;
     • easily commit, branch, and merge the code to easily maintain control of team’s projects.
   • notifications that automatically send emails to users about pull requests and comments; and more.
4. Easily scale the version control projects
   • CodeCommit repositories can scale up to meet your development needs.
   • The service can handle repositories with large numbers of files or branches, large file sizes, and lengthy revision histories.
5. Store anything, anytime
   • no limit on the size of repositories or the file types to store.
6. Integrate with other AWS and third-party services.
   • CodeCommit keeps your repositories close to your other production resources in the AWS Cloud, which helps increase the speed and frequency of your development lifecycle.
   • It is integrated with IAM and can be used with other AWS services and in parallel with other repositories.
7. Easy Access and Integration
   • Easily migrate files from other remote repositories.
     • migrate to CodeCommit from any Git-based repository.
   • use the AWS Management Console, AWS CLI, and AWS SDKs to manage your repositories.
   • can also use Git commands or Git graphical tools to interact with your repository source files.
     • AWS CodeCommit supports all Git commands and works with your existing Git tools.
     • You can integrate with your development environment plugins or continuous integration/continuous delivery systems.
8. High Availability and Durability
   • AWS CodeCommit stores your repositories in Amazon S3 and Amazon DynamoDB.
   • encrypted data is redundantly stored across multiple facilities.
   • increases the availability and durability of the repository data.
   • Unlimited Repositories
     • create as many repositories as you need
     • up to 1,000 repositories by default and no limits upon request.
     • You can store and version any kind of file, including application assets such as images and libraries alongside your code.
9. Notifications and Custom Scripts
   • receive notifications for events impacting your repositories.
   • Notifications will come in the form of Amazon SNS notifications.
   • Each notification will include a status message as well as a link to the resources whose event generated that notification.
   • Additionally, using AWS CodeCommit repository triggers, you can send notifications and create HTTP webhooks with Amazon SNS or invoke AWS Lambda functions in response to the repository events you choose.

work flow

• similar to Git-based repositories
• provides a console for easy creation of repositories and the listing of existing repositories and branches.
• find information about a repository and clone it to their computer, creating a local repo where they can make changes and then push them to the CodeCommit repository.
• Users can work from
  • the command line on local machines
  • or use a GUI-based editor.

setup

1. Create a Server from an Amazon Linux 2 AMI
2. Create IAM user for CodeCommit
   1. user:cloud_user
   2. User ARN: arn:aws:iam::183169071737:user/cloud_user
   3. Add permissions > Attach existing policies directly.
      1. AWSCodeCommitFullAccess policy
   4. user credentials:
      1. create access Key: for aws configure
         • AcessKeyID and cloud_user_accessKeys.csv
      2. create HTTPS Git credentials for AWS CodeCommit: for git clone
         • Username: cloud_user-at-183169071737
         • credentials: cloud_user_codecommit_credentials.csv
