💡 Hint

Common Mistakes

Using a feature or develop branch instead of master.

Forgetting to specify the branch condition.

The migration should run only on the master branch to avoid affecting other branches.

Fill both blanks to create a Jenkins pipeline step that runs migration script with environment variables.

    withEnv(['DB_USER=[1]', 'DB_PASS=[2]']) {
        sh './migrate.sh'
    }
}

Common Mistakes

Swapping username and password values.

Using generic words instead of credentials.

The environment variables DB_USER and DB_PASS are set to admin and password123 respectively for migration authentication.

5fill in blank

hard

Fill all three blanks to define a Jenkins pipeline stage that runs migration, verifies success, and cleans up.

Jenkins

stage('Migration') {
    steps {
        sh './[1]'
        sh './[2]'
        sh './[3]'
    }

Common Mistakes

Running deploy script instead of verify or cleanup.

Mixing the order of scripts.

The pipeline runs migrate.sh to migrate, verify.sh to check success, and cleanup.sh to clean temporary files.
