The Smart City sample can be deployed with Kubernetes.

Kubernetes Setup

  • Follow the instructions to setup your Kubernetes cluster.

  • Optional: setup password-less access from the Kubernetes controller to each worker node (required by make update):

ssh-keygen
ssh-copy-id <worker-node>
  • Start/stop services as follows:
mkdir build
cd build
cmake ..
make
make update # optional for private docker registry
make start_kubernetes
make stop_kubernetes

The command make update uploads the sample images to each worker node. If you prefer to use a private docker registry, configure the sample, cmake -DREGISTRY=<registry-url> .., to push images to the private registry after each build.

Multiple Office Start/Stop

The sample supposes dynamic office starting/stopping. You can selectively start and stop any office, as follows:

cmake -DNOFFICES=2 ..
make

SCOPE=cloud make start_kubernetes
SCOPE=office1 make start_kubernetes
SCOPE=office2 make start_kubernetes
...
SCOPE=office1 make stop_kubernetes
...
SCOPE=office1 make start_kubernetes
...
make stop_kubernetes  # cleanup all

Database High Availability

Specify the following optional parameters for cloud or office database high-availability settings:

HA_CLOUD=3 make start_kubernetes
...
HA_CLOUD=3 make stop_kubernetes

HA_CLOUD=3 HA_OFFICE=3 make start_kubernetes
...
HA_CLOUD=3 HA_OFFICE=3 make stop_kubernetes

Each database instance requires about 2GB memory.
