Variable Expression Limitations and Restrictions
The following limitations and restrictions apply to Harness variable expressions.
For general details about Harness variable expressions, see:
Limitations
- Harness does not support the Ternary conditional
?:
operator from JEXL. - Harness permits variables only within their scope. You will not see a variable available in a field where it cannot be used. For example, if you use a Service Config variable you cannot resolves its expression in the Pre-deployment section of a Workflow because the Service is not used in Pre-deployment.
- Do not use hyphens (dashes) in variable names, as some Linux distributions and deployment-related software do not allow them.
- A variable value (the evaluated expression) is limited to 256 KB.
Variable Expression Name Restrictions
A variable name is the name in the variable expression, ${variable_name}
.
Variable names may only contain a-z, A-Z, 0-9, _
. They cannot contain hyphens or dots.
The following keywords are reserved, and cannot be used as a variable name or property:
or and eq ne lt gt le ge div mod not null true false new var return shellScriptProvisioner
