TeamCity Parameters

TeamCity Parameters

TeamCity parameters let you inject configuration and secrets into builds.

Types

• Configuration parameters: referenced as %param.name%
• Environment variables: available as env.MY_VAR
• System properties: -Dproperty=value for JVM-based tools

Example usage (script step)

echo "Branch: %teamcity.build.branch%"
echo "API URL: %api.url%"

Best practices

• Use secure parameters for secrets
• Provide defaults and allow overrides via build triggers
• Prefer parameter references over hardcoding values
