For a parameterized assembly with an image tag selection, you will need the Active Choices<\/a> plugin<\/p>\n

Go to "Manage Jenkins<\/strong>"<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Section "Manage Plugins<\/strong>"<\/p>\n

\"\"<\/p>\n

 <\/p>\n

Go to the "Available<\/strong>" tab and select "Active Choices<\/strong>" in the search.<\/p>\n

\"\"<\/p>\n

Install it.<\/p>\n

 <\/p>\n

Create a "New Item<\/strong>" \u2013 "Pipeline<\/strong>", indicate that it will be a parameterized assembly, and add the parameter "Active Choices Parameter<\/strong>"<\/p>\n
