Description:
|
I manage to create a simple workflow that can show that the
`
{{
concurrency:1
`
}}
on stages has an issue:
```
{code}
import java.util.Random
def waiter(max) {
def rand = new Random()
def time = rand.nextInt(Integer.parseInt("${max}")+1)
echo "Waiting for ${time} seconds..."
sh "sleep ${time}s"
echo "You get served.."
}
stage name:'build', concurrency: 1
node { waiter(10) }
stage name:'concurrent', concurrency:1
node { waiter(20) }
stage name: 'deploy', concurrency: 1
node { waiter(30) }
```
{code}
To reproduce it:
1. Launch 2 instances of the workflow. The first will start, the second will wait the first one to leave the stage build.
2. When the first one leave the stage build, start a new instance of the workflow
The third instance will not wait the second instance to leave the stage build before starting.
