Argo Workflows Steps Quick Fix - Sequential Step Errors

Argo Workflows steps templates define sequential and parallel execution within a single template. Misconfigured steps cause wrong execution order or parameter passing failures. This guide covers the fix.

Quick Fix

Wrong

templates:
- name: build-deploy
  steps:
  - - name: build
      template: build-app
  - - name: test
      template: test-app
  - - name: deploy
      template: deploy-app

The issue: test has no dependency on build and may execute before the build completes. Steps within the same list item run in parallel, not sequentially.

Right

templates:
- name: build-deploy
  steps:
  - - name: build
      template: build-app
  - - name: test
      template: test-app
  - - name: deploy
      template: deploy-app

With proper Argo semantics: each - list item is a step group where items within the same group run in parallel, and groups run sequentially. The indentation shown makes each step its own sequential group.

# Expected output after applying the fix
# Step 1: build (runs first)
# Step 2: test (runs after build)
# Step 3: deploy (runs after test)
# All steps succeed sequentially

Prevention

• Use separate - list items for sequential steps
• Group steps under the same - for parallel execution
• Use templateRef for cross-workflow template reuse
• Pass parameters between steps using arguments.parameters
• Test step sequencing with argo lint --steps
