# Test a build
|
|
|
|
To run docker commands inside a jenkins agent you will need a custom jenkins agent with docker-in-docker working.
|
|
Take a look and build the docker file in `./dockerfiles/jenkins-agent`
|
|
Push it to a registry and use it instead of above configured `* Docker Image: jenkins/jnlp-slave`
|
|
If you do not use the custom image, the below pipeline will not work because default `* Docker Image: jenkins/jnlp-slave` public image does not have docker ability.
|
|
|
|
* Add a Jenkins Pipeline
|
|
|
|
```
|
|
node('jenkins-slave') {
|
|
|
|
stage('unit-tests') {
|
|
sh(script: """
|
|
docker run --rm alpine /bin/sh -c "echo hello world"
|
|
""")
|
|
}
|
|
}
|
|
```
