Part 1 Getting Started with DevOps, Git, and GitLab
Chapter 1: Understanding Life Before DevOps
Introducing the Hats for Cats web appBuilding and verifying code manuallyBuilding code manuallyVerifying code manuallyMore challenges of verifying codeSecurity-testing code manuallyStatic code analysisSecret detectionDynamic analysisDependency scanningContainer scanningManual security testing summaryPackaging and deploying code manuallyLicense compliance scanningDeploying softwareProblems with manual software development life cycle practicesSolving problems with DevOpsHow GitLab implements DevOpsSummary
Chapter 2: Practicing Basic Git Commands
Technical requirementsWhy use Git?What is a version control system?What problems does a VCS solve?Why Git is popularDrawbacks of GitCommitting code to keep it safeExcluding files from a repositoryTagging commits to identify versions of codeBranching code for developing in an isolated spaceGit commands for managing branchesHandling merge conflictsSyncing local and remote copies of repositoriesThe “golden” repositoryConfiguring remote repositoriesPushingFetchingPullingAdditional resources for learning GitSummary
Chapter 3: Understanding GitLab Components
Technical requirementsEmphasizing the “why” over the “how”Introducing the GitLab platformWhat is GitLab?What problem does GitLab solve?The verify, secure, and release stagesOrganizing work into projects and groupsExample – organizing your Hats for Cats work Tracking work with issuesThe structure of a GitLab issueThe kinds of tasks that issues can representLabelsIssue workflowsEditing files safely with commits, branches, and merge requestsCommit historyMerging one Git branch into anotherThe three amigos – issues, branches, and merge requestsWhen two amigos are enoughHow are issues and merge requests different?Enabling DevOps practices with GitLab flowSummary
Chapter 4: Understanding GitLab’s CI/CD Pipeline Structure
Technical requirementsDefining the terms pipeline, CI, and CDUnderstanding what a pipeline isDefining one pipeline per projectUnderstanding different uses of the term “pipeline”Viewing a list of pipelinesCI – finding out if your code is goodCD – finding out where your code should go (and putting it there)GitLab RunnersParts of a pipeline – stages, jobs, and commandsStagesJobsCommandsFitting the pipeline pieces togetherRunning GitLab CI/CD pipelinesBranch pipelinesGit tag pipelinesOther types of pipelinesSkipping pipelinesReading GitLab CI/CD pipeline statusesConfiguring GitLab CI/CD pipelinesSummary
Part 2 Automating DevOps Stages with GitLab CI/CD Pipelines

Chapter 5: Installing and Configuring GitLab Runners
Technical requirementsDefining GitLab runners and their relationship to CI/CDGitLab Runner is an open source application written in GoGitLab Runner runs CI/CD jobs specified in .gitlab-ci.ymlThe runner architecture and supported platformsGitLab Runner is supported on most platforms and architecturesRunners can be specific, group, or sharedEach runner has a defined executorRunner tags restrict which runners can pick up which jobsInstalling the Runner agentInstalling GitLab RunnerRegistering a runner with GitLabConsiderations regarding the various runner types and executorsPerformance considerationsSecurity considerationsMonitoring considerationsSummary
Chapter 6: Verifying Your Code
Technical requirementsBuilding code in a CI/CD pipelineCompiling Java with javacCompiling Java with MavenCompiling C with Gnu Compiler Collection (GCC)Storing built code as artifactsChecking code quality in a CI/CD pipelineEnabling Code QualityViewing Code Quality resultsRunning automated functional tests in a CI/CD pipelineEnabling automated functional testsViewing automated functional test resultsFuzz testing in a CI/CD pipelineThe architecture and workflow of fuzz testingA fuzz testing workflowViewing the results of fuzz testingExtra considerations when fuzz testingFuzz testing with a corpusChecking accessibility in a CI/CD pipelineEnabling accessibility testingViewing accessibility testing resultsAdditional ways to verify your codeCode coverageBrowser performance testingLoad performance testingSummary
Chapter 7: Securing Your Code
Technical requirementsUnderstanding GitLab’s security scanning strategyGitLab uses open-source scannersScanners are packaged as Docker imagesSome scanners use different analyzers for different languagesVulnerabilities don’t stop the pipelineFindings appear in three different reportsPipelines can use non-GitLab-provided scannersUsing SAST to scan your source code for vulnerabilitiesUnderstanding SASTEnabling SASTConfiguring SASTViewing SAST’s findingsUsing Secret Detection to find private information in your repositoryUnderstanding Secret DetectionEnabling and configuring Secret DetectionViewing Secret Detection’s findingsUsing DAST to find vulnerabilities in web applicationsUnderstanding DASTEnabling and configuring DASTViewing DAST’s findingsUsing Dependency Scanning to find vulnerabilities in dependenciesUnderstanding Dependency ScanningEnabling and configuring Dependency ScanningViewing Dependency Scanning’s findingsUsing Container Scanning to find vulnerabilities in Docker imagesUnderstanding Container ScanningEnabling and configuring Container ScanningViewing Container Scanning’s findingsUsing License Compliance to manage licenses of dependenciesUnderstanding License ComplianceEnabling and configuring License ComplianceViewing License Compliance’s findingsUsing IaC Scanning to find problems in infrastructure configuration filesUnderstanding IaC ScanningEnabling and configuring IaC scanningViewing IaC Scanning’s findingsUnderstanding the different types of security reportsManaging security vulnerabilitiesIntegrating outside security scannersSummary
Chapter 8: Packaging and Deploying Code
Technical requirementsStoring code in GitLab’s package registry for later re-useLocating GitLab’s container and package registriesGetting started with the package registrySupported package formatsAuthenticating to the registryBuilding and pushing packages to the package registryBuilding and pushing packages to the container registryStoring code in GitLab’s container and package registries for later deploymentUsing images from the container registryUsing packages from the package registryDeploying to different environments using GitLab FlowDeploying to a review app for testingDeploying to real-world production environmentsDeploying to a Kubernetes clusterThe CI/CD workflowA GitOps workflowSummary
