Jenkins Pipeline Parameters and Waiting for manual inputs

Parameters section

The parameters section enumerates the parameters to the pipeline with their default values. The four parameters used in the template, and their meanings are discussed in Deploying a Jenkins CI/CD Pipeline

note that parameters are immutable, and once set at pipeline (or scope section) start, cannot be changed

CODE

parameters {
    string(name: 'domainName', defaultValue: 'services_tier.datamigrators.io:59445', description: 'DataStage Service Tier')
    string(name: 'serverName', defaultValue: 'engine_tier.datamigrators.io', description: 'DataStage Engine Tier')
    string(name: 'projectName', defaultValue: 'wwi_jenkins_ds117', description: 'Logical (unsuffixed) Project Name')
    string(name: 'environmentId', defaultValue: 'ci', description: 'Environment Identifer')
}

When run interactively, the user will be prompted for these at pipeline start time like so:

Similarly, users can be prompted to make a choice from a selection…

CODE

parameters {
    choice (name: 'targetEnvironment', choices: ['qa', 'perf', 'prod'], description: 'Deploy to environment')
}
