Working

Understanding AWS CodeCommit
  1. Use the AWS CLI/CodeCommit console for creating CodeCommit repository.
  2. From development machine, use Git to run git clone command, with name of CodeCommit repository to create local repo connected to CodeCommit repository.
  3. Use local repo on development machine to make changes – add/ edit/delete files, and then run git add command for staging modified files locally. After which, run git commit command for committing files locally, and then run git push command to send files to CodeCommit repository.
  4. Run git pull command to synchronize files in CodeCommit repository with local repo and download changes from other users to work with latest version of files.

Tasks include:

  • Create a CodeCommit Repository
  • Add Files to Repository
  • Browse the Contents of Repository
  • Create and Collaborate on a Pull Request

CodeCommit Repositories
