UserRemoteConfigs: Scm . } } the when { } }, pipeline { Earlier in this blog post, you created several IAM users with read-only access to EC2. Conditional step (single) This build step allows you to select any build step and define a condition to control whether the step should be executed.

For example, you could define all of the IAM usernames you want in an input variable in live/global/iam/variables.tf: If you were using a general-purpose programming language with loops and arrays, you would configure each IAM user to use a different name by looking up index i in the array var.user_names: In Terraform, you can accomplish the same thing by using count along with the following: Putting these together, you get the following: Now when you run the plan command, youll see that Terraform wants to create three IAM users, each with a unique, readable name: Note that after youve used count on a resource, it becomes an array of resources rather than just one resource. Jenkins Pipeline allows you to compose multiple steps in an easy way that can help you model any sort of automation process. Is this color scheme another standard for RJ45 cable? I am trying to write when statement in the single stage block in Jenkinsfile. Or use a block with a steps directive node. To learn more, see our tips on writing great answers.

Variable assignment 1.2.1. If-Statements with the count parameter. For example, here is the Terraform code to convert the list of names in var.names to uppercase: If you run terraform apply on this code, you get the following output: Just as with Pythons list comprehensions, you can filter the resulting list by specifying a condition: Running terraform apply on this code gives you this: Terraforms for expression also allows you to loop over a map using the following syntax: Here, MAP is a map to loop over, KEY and VALUE are the local variable names to assign to each key-value pair in MAP, and OUTPUT is an expression that transforms KEY and VALUE in some way.

Depending on which upstream job triggered my job, I don't necessarily need to run all of the stages in my pipeline, so I want to specify a list of triggers for each stage. booleanParam () Running multiple steps - Jenkins Leqembi is the first amyloid beta-directed antibody to be converted from an accelerated approval to a traditional approval for the treatment of Alzheimers disease.
