Deploy a website from a repository

Git-based deployment connects a reviewed commit to a reproducible build and an environment. The host checks out the commit, installs locked dependencies, runs validation, publishes artifacts, and preserves logs for rollback.

At a glance

Question	Practical answer
When is it useful?	A push to main deploys production, while a pull request creates an isolated preview URL for review before merge.
What should you do?	Connect a sample repository to a host, pin runtime versions, deploy one visible change through a pull request, and record the rollback path.
How do you know it worked?	The deployed page identifies the expected commit, a failed check blocks promotion, and the previous successful version can be restored.
Common failure	Never make the provider dashboard the only source of configuration; keep build settings documented and secrets outside Git.

The important idea is not to stop at a definition: connect the concept to a small example and observable evidence.

Worked example

A push to main deploys production, while a pull request creates an isolated preview URL for review before merge.

Before acting, write the success signal. Change one condition at a time, observe the result, and record assumptions. For Deploy a website from a repository, this separates what you know from what you are merely guessing.

Practice in 20–30 minutes

Goal: Connect a sample repository to a host, pin runtime versions, deploy one visible change through a pull request, and record the rollback path.

1. Record the starting state and your prediction.
2. Implement the smallest version without adding unnecessary tools.
3. Change exactly one input or constraint and repeat.
4. Save a command, screenshot, output, or checklist as evidence.

Expected result: The deployed page identifies the expected commit, a failed check blocks promotion, and the previous successful version can be restored.

What can go wrong

Never make the provider dashboard the only source of configuration; keep build settings documented and secrets outside Git.

When the result differs from your prediction, do not change many things at once. Check inputs, versions, environment, permissions, and logs, then repeat from the smallest example.

Definition of done

• I can explain the concept in my own words.
• I completed the small example and kept evidence.
• I know one failure mode and how to check it.
• Someone else can repeat the work without guessing missing steps.

Go deeper

Use the linked resource or repository at the end of the page when you need a full implementation. Check current versions before applying commands to a real project.
