h2. Configure server to access Kubernetes cluster

On the machine running QuickBuild server, make sure that the OS account [running QuickBuild service|Install As System Service] is set up appropriately so that it can run below command to connect to desired Kubernetes cluster:
{code}kubectl cluster-info{code}

h2. Set up firewall rule to allow node ports

Build agents are running as pods in Kubernetes cluster, and these pods are exposed via services with type "NodePort". QuickBuild server has to access these node ports, so appropriate firewall rule may need to be set up to allow this. For Google Kubernetes Engine, an example firewall rule can be as following:


{anchor:create build agent image}

h2. Create build agent image

Build agent docker image needs to be configured with your build environment as well as QuickBuild build agent. Below is an example to create a Debian Linux image only with OpenJDK and build agent installed.

# Assume we have build agent installed at _/path/to/buildagent_. First run the build agent to make sure it can connect with the build server.
# Create file _/path/to/buildagent/Dockerfile_ with below content:
FROM openjdk:8-jdk
ADD . /app
CMD ["/app/bin/wrapper-linux-x86-64", "/app/conf/wrapper.conf"]
# Change to directory _/path/to/buildagent_, and run below command
sudo docker build -t youraccount/qbagent:latest .
# Then publish the built image:
sudo docker push youraccount/qbagent:latest

h2. Enable Kubernetes plugin in QuickBuild
Login to QuickBuild server, and enable the Kubernetes plugin in _Administration/Plugin Management_ page as demonstrated below:



h2. Add Kubernetes cloud profile in QuickBuild

Then one can follow the [cloud profiles|Working with Cloud Profiles] guide to create cloud profiles using Kubernetes launchers like below:
