Steps within stages in Jenkins - Step-by-Step Execution

Process Flow - Steps within stages

Start Pipeline

↓

Enter Stage

↓

Execute Step 1

↓

Execute Step 2

↓

Execute Last Step

↓

Exit Stage

↓

Next Stage or End Pipeline

The pipeline starts, enters a stage, runs each step in order, then exits the stage and moves on.

Execution Sample

Jenkins

pipeline {
  agent any
  stages {
    stage('Build') {
      steps {
        echo 'Compiling code'
        sh 'make build'
      }
    }
  }
}

This pipeline runs a 'Build' stage with two steps: printing a message and running a build command.

Process Table

Step	Action	Command/Message	Result/Output
1	Enter Stage	Build	Stage 'Build' started
2	Execute Step	echo 'Compiling code'	Prints: Compiling code
3	Execute Step	sh 'make build'	Runs build command, outputs build logs
4	Exit Stage	Build	Stage 'Build' completed

💡 All steps in the 'Build' stage executed successfully, stage ends.

Status Tracker

Variable	Start	After Step 2	After Step 3	Final
Stage Status	Not started	Running	Running	Completed
Build Output	None	Compiling code printed	Build logs generated	Build logs available

Key Moments - 2 Insights

Why do steps run one after another inside a stage?

Steps inside a stage run sequentially as shown in the execution_table rows 2 and 3, ensuring each command finishes before the next starts.

What happens if a step fails inside a stage?

If a step fails, the pipeline stops executing further steps in that stage, so the exit step (row 4) would not be reached.

Visual Quiz - 3 Questions

Look at the execution table, what is the output after Step 2?

A Runs build command

B Prints: Compiling code

C Stage 'Build' completed

D No output yet

💡 Hint

Check the 'Result/Output' column for Step 2 in the execution_table.

At which step does the stage status change to 'Completed'?

A Step 2

B Step 3

C Step 4

D Start of pipeline

💡 Hint

Look at the variable_tracker row for 'Stage Status' and see when it becomes 'Completed'.

If the 'sh make build' command fails, what happens next?

A Stage exits immediately without completing all steps

B Stage restarts automatically

C Pipeline continues to next step

D Pipeline skips to next stage

💡 Hint

Refer to key_moments explanation about step failure stopping the stage.

Concept Snapshot

Jenkins pipeline stages contain steps.
Steps run one by one inside a stage.
Each step executes a command or action.
If a step fails, the stage stops.
Stages help organize pipeline tasks clearly.

Full Transcript

In Jenkins pipelines, a stage groups related steps. When the pipeline runs, it enters a stage and executes each step in order. For example, in the 'Build' stage, it first prints a message, then runs a build command. Each step must finish before the next starts. If any step fails, the stage stops immediately. After all steps complete, the stage ends and the pipeline moves on. This flow helps organize tasks and track progress clearly.
