		h2. Kubernetes cloud profile
		Cloud profiles rely on cloud providers to do its job. QuickBuild 8.0 ships with the Kubernetes cloud provider. To use it, one has to enable the Kubernetes plugin by providing a configuration file in _Administration/Plugin Management_ page as demonstrated below:

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

		You should use your own docker image when define the Kubernetes profile. {anchor:create build agent image}The image should be pre-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.

		h2. Create build agent image
		You should use your own docker image when define the Kubernetes profile. The image should be pre-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:
		{code}
		FROM openjdk:8-jdk
		ADD . /app
		EXPOSE 8811
		CMD ["/app/bin/wrapper-linux-x86-64", "/app/conf/wrapper.conf"]
		{code}
		# Change to directory _/path/to/buildagent_, and run below command
		{code}
		docker build -t youraccount/qbagent:latest .
		{code}
		# Then publish the built image:
		{code}
		docker push youraccount/qbagent:latest
		{code}

		With this example, you should use docker image _youraccount/qbagent:latest_ when define the Kubernetes profile above
