## ${docGenDescription}
|
|
|
|
## Prerequisites
|
|
|
|
* The Jenkins should be running on kubernetes.
|
|
* An environment variable `ON_K8S` should be created on Jenkins and initialized to `true`. This could for example be done via _Jenkins_ - _Manage Jenkins_ - _Configure System_ - _Global properties_ - _Environment variables_

## Example 1: Run a closure in a single container pod
|
|
|
|
```sh
|
|
# set environment variable
|
|
export ON_K8S=true"
|
|
```
|
|
|
|
```groovy
|
|
dockerExecuteOnKubernetes(script: script, dockerImage: 'maven:3.5-jdk-7'){
|
|
sh "mvn clean install"
|
|
}
|
|
```
|
|
|
|
In the above example, a pod will be created with a docker container of image `maven:3.5-jdk-7`. The closure will be then executed inside the container.
|
|
|
|
## Example 2: Run a closure in a multi-container pod
|
|
|
|
```sh
|
|
# set environment variable
|
|
export ON_K8S=true"
|
|
```
|
|
|
|
```groovy
|
|
dockerExecuteOnKubernetes(script: script, containerMap: ['maven:3.5-jdk-8-alpine': 'maven', 's4sdk/docker-cf-cli': 'cfcli']){
|
|
container('maven'){
|
|
sh "mvn clean install"
|
|
}
|
|
container('cfcli'){
|
|
sh "cf plugins"
|
|
}
|
|
}
|
|
```
|
|
|
|
In the above example, a pod will be created with multiple Docker containers that are passed as a `containerMap`. The containers can be chosen for executing by referring their labels as shown in the example.
|
|
|
|
## Example 3: Running a closure in a dedicated container of a multi-container pod
|
|
|
|
```sh
|
|
# set environment variable
|
|
export ON_K8S=true"
|
|
```
|
|
|
|
```groovy
|
|
dockerExecuteOnKubernetes(
|
|
script: script,
|
|
containerCommands: ['selenium/standalone-chrome': ''],
|
|
containerMap: ['maven:3.5-jdk-8-alpine': 'maven', 'selenium/standalone-chrome': 'selenium'],
|
|
containerName: 'maven',
|
|
containerPortMappings: ['selenium/standalone-chrome': [containerPort: 4444, hostPort: 4444]]
|
|
containerWorkspaces: ['selenium/standalone-chrome': '']
|
|
){
|
|
echo "Executing inside a Kubernetes Pod inside 'maven' container to run Selenium tests"
|
|
sh "mvn clean install"
|
|
}
|
|
```
