Before we begin, ensure you have:

GitLab account (Free or higher tier)

Basic understanding of Git

Familiarity with command line

Basic development knowledge

Core Components Overview 🎯

$1

The foundation of GitLab, handling your code and version control.

$1

``bash

Clone a repository

git clone https://gitlab.com/username/project.git

Create a new branch

git checkout -b feature/new-feature

Push changes

git push origin feature/new-feature

`

$1

`yaml

.gitignore example

node_modules/

*.log

.env

dist/

`

Automate your build, test, and deployment processes.

$1

`yaml

.gitlab-ci.yml

stages:

- build

- test

- deploy

build_job:

stage: build

script:

- npm install

- npm run build

test_job:

stage: test

script:

- npm run test

deploy_job:

stage: deploy

script:

- echo "Deploying application..."

Best Practices for Each Component 💡

$1

Use meaningful branch names

Write clear commit messages

Keep repositories focused

Implement branch protection

`bash

Good commit message

git commit -m "feat: add user authentication system

Add login/logout functionality

Implement JWT tokens

Add password reset flow"

`

$1

Keep pipelines fast

Use caching effectively

Implement proper staging

Monitor pipeline metrics

`yaml

Optimized pipeline

cache:

key: ${CI_COMMIT_REF_SLUG}

paths:

- node_modules/

- .npm/

`

$1

Use templates

Apply proper labels

Link related items

Regular triage

`markdown

/label ~bug ~needs-investigation

/assign @qa-team

/milestone %"Next Release"

`

$1

Clear structure

Regular updates

Version control

Link to issues/MRs

`markdown

Tag properly

Clean old images

Use multi-stage builds

Implement scanning

`dockerfile

Optimized Dockerfile

FROM node:alpine AS builder

WORKDIR /app

COPY package*.json ./

RUN npm ci

COPY . .

RUN npm run build

FROM nginx:alpine

COPY --from=builder /app/dist /usr/share/nginx/html

`

$1

Regular scanning

Quick vulnerability fixes

Secret management

Access control

`yaml

Security scanning

security_scan:

script:

- security-tool scan

artifacts:

reports:

security: gl-security-report.json
