Parameters
Parameters are names of placeholders that exist in DevOps resources. They're available to all resources within the pipeline.
All parameters used in the pipeline must have a value before the pipeline is run. When the pipeline is run, you have the option to override the default value of the parameter with an argument value for that particular run. If a parameter has both argument and default value, then the argument value takes precedence.
Placeholders can be used as input in DevOps resources such as pipeline, stage, or artifact resource. For example, a placeholder can be used while adding a DevOps artifact resource such as in the artifact version or a Container Registry tag. Any placeholders in the artifacts are substituted by the corresponding parameter values by selecting Allow parameterization check box in the artifact configuration. For more details, see Managing Artifacts.
- In Kubernetes manifest, you can define the replicas as
replicas: ${nginxReplicaCount}. - In the instance group deployment specification, you can set an environment
variable version as
version: ${appVersion}. For more details, see deployment configuration file.
