# Ruleset Workflow Strategy Plugin

The Ruleset Workflow Strategy Plugin (exclusive to Rundeck Enterprise) allows you to define a set of rules to describe when and if steps in the workflow should run.

The plugin can be selected in the Workflow Strategy list in the the Edit Job page.

The rules configuration value is a multiline block of text in the following format.

# Rules syntax

Rules define how each step should run. You can add one rule per-line. Rules are additive, and you can define multiple rules for each step. Rules are in the form:

STEP [directive] [conditions...]

This indicates which step or steps the rule applies to, and any directives or conditions for the step. The rule must have a directive or condition, or both.

# Step

Specifies the step or steps that the rule applies to. You must include the [ and ] characters:

  • [X]: Applies to a single step, the named or numbered step X. You can use the step number, e.g. [1] or the label, e.g. [Deploy QA] (case sensitive).
  • [X,Y,Z...]: Applies to multiple steps. Separate multiple steps with a comma, e.g. [1,2,3]
  • [1-3]: Applies to steps 1 through 3
  • [1-3,5-7]: Applies to steps 1 through 3 and 5 through 7
  • [*]: Applies to all steps

# Directive

Directives optionally define when a step should start. You can define a directive rule for all steps [*] using run-at-start or run-in-sequence.

  • run-at-start: Run at workflow start time. The indicated steps will start immediately when the workflow starts.
  • run-in-sequence: Run after the previous step in sequence is run or is skipped.
  • run-after:X[,Y[,Z..]]: Run after one or more steps run or are skipped.


Step Numbers and Names can be used on run-after:[], but in the case that the Step Name includes spaces, this condition must be encapsulated in double quotes, e.g. [Step Two] "run-after:Step One"

# Conditions

Conditions can define additional checks that must pass before a step can run, or determine when a step can be skipped. For example:

  • if:expression
  • unless:expression

expression defines a comparison or match that will be checked. Valid expressions are:

  • key.name==string: a context variable such as option.myoption has a certain value
  • key.name!=string: not-equal check
  • key.name=~pattern: regular expression match
  • key.name!~pattern: negative regular expression match
  • !key.name context: variable is unset
  • key.name>=number: greater than or equal to check
  • key.name<=number: less than or equal to check
  • key.name>number: greater than check
  • key.name<number: less than check

Note: Curly braces are not needed to reference context variable key names.

# Examples

Run steps 2 and 5 only after step 1 is done:

[2,5] run-after:1

Choose between 5 and 6 based on an option value:

[*] run-in-sequence
[5] if:option.env==QA
[6] unless:option.env==PRODUCTION

Run step 1, then steps 2 and 3 in parallel, then step 4:

[2] run-after:1
[3] run-after:1
[4] run-after:2,3

Run steps only if two different conditions are met:

[1] run-in-sequence
[2] if:option.1=yes if:option.2=yes
[3] if:option.1=yes if:option.2=no
[4] if:option.1=no if:option.2=yes
[5] if:option.1=no if:option.2=no

Based on the ruleset defined above, if option 1 is "yes" and option 2 is "no" then job step 3 would run after 1. If option 1 is "no" and option 2 is "yes" then job step 4 would run after 1.
