Docker Build and Development Environment for OSv
Full Description

Docker Build/Development Environment for OSv

This docker container is intended to be a build/development environment for OSv, OSv Application/Appliances.

OSv is an amazing Operating System by Cloudius Systems designed for cloud workloads. Visit http://osv.io/ for more information.

Building locally

docker build -t cloudrouter/osv-builder .

Launching an interactive session

docker run -it \
  --volume ${HOST_BUILD_DIR}:/osv/builder \
  cloudrouter/osv-builder

This will place you into the OSv source clone. You can work with it as you normally would when working on OSv source, apps, build scripts etc. For example, you can run the following commands, once the above docker run commands has been executed, to build and run a tomcat appliance.

./scripts/build image=tomcat,httpserver
./scripts/run -V

The osv Command

Note that the commands you run can be prefixed with osv, the source for which is available at assets/osv. For example you can build by:

docker run \
  --volume ${HOST_BUILD_DIR}:/osv/build \
  cloudrouter/osv-builder \
  osv build image=opendaylight

Note that the osv script, by default provides the following convenience wrappers:

Command Mapping
build args scripts/build
run args scripts/run.py
appliance name components description scripts/build-vm-img
clean make clean

If any other command is used, it is simply passed on as scripts/$CMD "$@" where $@ is the arguments following the command.

You could also run commands as:

docker run \
  --volume ${HOST_BUILD_DIR}:/osv/build \
  cloudrouter/osv-builder \
  ./scripts/build image=opendaylight

Running Capstan

This container also comes with Capstan pre-installed. However, to use Capstan, you'll have to run the container with the --privileged option set as it requires the KVM kernel module.

Examples

List the images that we already have on the host by mounting the ~/.capstan/repository directory. This allows reuse of images across runs of the container.

docker run \
  --privileged \
  --volume ${HOME}/.capstan/repository:/capstan-repository \
  cloudrouter/osv-builder \
  capstan images

Capstan build and run iperf app:

[abn@zoidberg ~]$ sudo docker run -it \
  --privileged \
  cloudrouter/osv-builder
bash-4.3# cd apps/iperf
bash-4.3# capstan build

Building appliance images

If using the pre-built version from docker hub, use cloudrouter/osv-builder instead of osv-builder.

HOST_BUILD_DIR=$(pwd)/build
docker run \
  --volume ${HOST_BUILD_DIR}:/osv/build \
  osv-builder \
  osv appliance zookeeper apache-zookeeper,cloud-init "Apache Zookeeper on OSv"

If everything goes well, the images should be available in ${HOST_BUILD_DIR}. This will contain appliance images for QEMU/KVM, Oracle VirtualBox, Google Compute Engine and VMWare Virtual Machine Disk.

Note that we explicitly disable the build of VMware ESXi images since ovftool is not available.

For more information regarding OSv Appliances and pre-built ones, refer here.
