Stage 6 - Working with Remote Repositories and GitHub

Up to now, task-service could be developed and debugged entirely locally. The next step is making it collaborative: publishing the current local branch so the team can fetch, review, and extend it.

Local and remote Git repositories

Local vs remote is an explicit boundary

Your local repository has the latest state you currently work with. A remote repository is the shared copy, usually on GitHub. They do not synchronize automatically every minute unless you use automation or pull actions in your editor.

So if teammate Anna pushed new work, your machine stays old until you fetch/pull. This is good: you control when to integrate remote updates.

One local repository to remote

Imagine your current project already has local commits. Add GitHub as remote origin and publish main:

git remote add origin https://github.com/your-user/task-service-tutorial.git
git branch -M main
git push -u origin main
``+

`origin` is a convention. `-u` links local main with remote main, so later `git push` / `git pull` know destination automatically.

## Cloning when repo already exists

If a repository already lives in GitHub and a new teammate joins:

```bash
git clone https://github.com/example-org/task-service-tutorial.git
cd task-service-tutorial
git remote -v

git clone configures the remote automatically.

fetch vs pull in project rhythm

git fetch downloads remote changes metadata and refs but does not touch working files yet.

git pull does fetch + integrate into current branch immediately.

In task-service, use fetch when you want to inspect remote commits first, pull when you already agree to sync.

Command	What it does	Best moment
`git remote -v`	Shows remote target mapping	Before first push/pull operations
`git fetch`	Safe: updates local remote-tracking refs	Before manual review of incoming commits
`git pull`	Fetch + merge/rebase current branch	During routine syncing with team branch
`git push`	Send local commit history to remote	Publish ready branch work

Stage 7 will build on this with PRs and review comments, so this step creates the collaboration infrastructure.

Operational check for real teams

Before pushing anything, make sure your branch is based on up-to-date main and your remote is configured as expected. In many incident cases, errors come from pushing to the wrong fork or from stale local main.

A stable remote routine:

git switch main
git pull
git switch <feature>
run change + commit
git push

This routine turns remote collaboration into repeated, predictable actions and is easier to automate than ad-hoc commands.

Keep secrets and credentials out of history

Remote workflows often fail because credentials accidentally enter source files. For task-service, keep tokens outside repo and use environment files or CI secrets.

Git cannot protect bad security habits by itself; it only protects history. Process and policy do.
