To create the parameters, we are going to enter into the “Configure” tab in our pipeline, click on “This project is parameterized”, once enabled, click on “Add parameter” and select “String Parameter” to create our image input box.The Active Choices plugin is used in parametrized freestyle Jenkins jobs to create scripted, dynamic and interactive job parameters. AWS Credentials are already configured in your Jenkins agent.A scripted Active Choices Parameter that pulls all S3 buckets to select where to upload the image.Īnd as a pre-requisite you will need the following things:.An input text box for your image name.An input string parameter for the image URL with an HTML Reactive Reference Parameter to preview the image.To accomplish that, you will need the following things: You also want to be able to list the S3 directories and determine in which directory will be the asset uploaded. Suppose you do now want your team to have direct access to AWS management console to upload your assets to S3, since it will incur operational overheat (Users creation, permissions, policies…), instead you would prefer to centralize the image uploading for your assets in Jenkins avoiding giving individual credentials with S3-specific permissions to users.

When you’ve to manage pipelines that are not the same, you will see that there are certain cases when the parameters provided by Jenkins are not enough because of its static nature, in these cases, the plugin “Active Choices” comes to enrich your parameterization options allowing you to pass reactive references between parameters and render custom HTML in your parameterization options. which environment should be deployed, with what name, if it should execute test…) Jenkins currently allows you to use some predefined parameters like choice, checkbox or string parameter. Usually, when there are hundreds of services to deploy, the pipeline is parameterized to allow you to select from only one pipeline, multiple kinds of deployment, (i.e. Active Choices parameters can be dynamically updated and can be rendered as combo-boxes, check-boxes, radio-buttons, or rich HTML UI widgets.” 3- A practical example of the Active Choices plugin in AWS: Preview and upload an image to an existing S3 bucket.ġ- What is this plugin called “Active Choices” and why is it so useful?Īs described in its docs: “The Active Choices plugin is used in parametrized freestyle Jenkins jobs to create scripted, dynamic and interactive job parameters.2- How does the plugin “Active Choices” works?.1- What is this plugin called “Active Choices” and why is it so useful.
