Lightning Talk: How Kubernetes is Helpful for Accelerating Machine Learning Research and Engineering [I] - Hitoshi Mitake, NTT Labs
In this lightning talk, the presenter shares his experience on helping machine learning research and engineering with kubernetes. k8s is not only a tool for managing microservices but also helpful for executing batch jobs like learning phase of deep learning frameworks and stateful services that provides data for the learning tasks. The presenter and his collaborators has been building and managing k8s cluster for TensorFlow learning tasks and HDFS as its learning data source. In addition, thanks to the pluggable scheduler architecture of k8s, their custom scheduler enshorts execution the learning tasks effecitvely and hides usage of network equipments and complex heterogeneous computational devices (e.g. GPUs) from researchers.

Lightning Talk: Cluster Insights [B] - Xin Ma, eBay
As the footprint of our K8 clusters increased across eBay data centers, many work loads were on boarded onto these clusters. With different work loads running across different clusters, cluster operations and insights into these applications has become an interesting problem. We wanted to know the footprint of these applications across different clusters in our data centers. One of the most obvious solutions is to query against different api servers and derive insights. However as the scale increased querying api servers has become a challenge and we could not get data in real time. To solve these problems, we developed an application called kube watch. Kube watch helps collects data for various resources from different clusters and persists into data stores. By building different dashboards using this data it helped us gain insights into the clusters in real time. During this talk we shall go through the kube watch system, its architecture and the problems it has helped us to solve.

Lightning Talk: Telepresence: Local Development & Debugging of Remote Kubernetes Services - Abhay Saxena, Datawire
Developers who use Kubernetes for multi-container applications face a conundrum: develop locally or on a remote Kubernetes cluster. Local development adds complexity to your development environment, since you have to run (and maintain!) your entire multi-container app locally. On the other hand, a remote Kubernetes cluster doesn’t lend itself to live coding and debugging.

In this talk, we will talk about Telepresence (https://www.telepresence.io), an open source tool for Kubernetes that lets you develop and debug a service locally, while setting up a bidirectional proxy to a remote Kubernetes cluster. With Telepresence, you can make a quick change to a service, save, and test it -- while that service has full access to Kubernetes environment variables, ConfigMap, secrets, and other services running in your Kubernetes cluster.

Lightning Talk: Templating K8s: Easily Managing Applications via Common Configuration [B] - Don Steffy & Anubhav Aaeron, Oath
Like many other companies, Yahoo is working to containerize many legacy applications, managed with Kubernetes. In order to onboard several hundred applications and libraries, Kubernetes configuration files are created for each application and multiple CI/CD environments, which leads to thousands of similar YAML files across all applications.

In order to onboard all applications seamlessly, and also be able to centrally make incremental updates to the Kubernetes configuration files with no disruption to customers, some kind of standardization is required. We tested many existing options, looking for a tradeoff between simplicity and power, and decided on centrally-managed templates for the configuration files.

A very simple yaml interface with standard technical verbiage was provided for customers to onboard their applications. This paper describes the design, user experience, and outcomes of creating these templates, which allowed developers with no Kubernetes experience to onboard their application quickly, often in less than a day.

Lightning Talk: Testing Kubernetes Patches with kube-spawn, the a local, multi-node Kubernetes Cluster Tool [B] - Chris Kuhl, Kinvolk
kube-spawn is a tool for running local, multi-node Kubernetes clusters on Linux machines. It was originally created as a means to test Kubernetes patches locally in a multi-node environment. Unlike other tools of its kind, it does not use VMs nor Docker app containers. Instead, it utilizes OS containers run with systemd-nspawn. As such, one can run a local, many-node cluster on modest hardware, with each node running a full OS, by default CoreOS's Container Linux.

Lightning Talk: Moving Fast with Microservices: Building and Deploying Containerized Applications in a Cloud-Native World - Micha Hernandez van Leuffen, Wercker
As software becomes more and more complex, we, as software developers, have been splitting up our code into smaller and smaller components. This is also true for the environment in which we run our code: going from bare metal, to VMs to the modern-day Cloud Native world of containers, schedulers and microservices.While we have figured out how to run containerized applications in the cloud using schedulers, we've yet to come up with a good solution to bridge the gap between getting your containers from your laptop to the cloud.

How do we build software for containers? How do we ship containers? How do we do all of it without shooting ourselves in the foot? In this talk, we'll explore how current delivery systems are falling behind, and how we need to change the mental model, create new best-practices and treat containers as a first-class citizen.

Lightning Talk: CRI Proxy: Solving the Chicken-and-Egg Problem of Running a CRI Implementation as a DaemonSet [I] - Piotr Skamruk, Mirantis
CRI allows for special-purpose CRI implementations such as Virtlet, which makes it possible to run VMs as if they were containers. Still, deployment of these CRI implementations may bring us back to pre-container days, because we run into problems with additional required software such as libvirt, the need to configure the operating system on the node in different ways, and so on. We can also have problems with upgrading the CRI implementation apps, because unlike other components, they require special treatment. It would be nice if we could use the deployment power of k8s to install these apps on some of the nodes.
Further complicating matters is the fact that if your CRI doesn't support Docker images, and is too different from Docker, you need to install Kubernetes components such as kube-proxy and a CNI plugin in a special way, meaning that you have to prepare special-purpose CRI nodes in a very special way.
Even if you just want to create a quick demo of your CRI that runs on Kubernetes clusters deployed using a popular tool such as kubeadm, you may need to tweak the node config just a bit to make this happen.

DaemonSet seems like it might be the right choice for a CRI implementation, but here we run into the chicken-and-egg problem, as a CRI implementation is required to be running on the node in order to run any pods there.
Enter CRI Proxy. CRI requests that deal with plain pods are handled by the primary CRI implementation (such as docker-shim), while requests that are marked in special way (using pod annotations and image name conventions) get directed to the special-purpose CRI implementation. This way, the deployment headache almost goes away - all you have to do is install CRI Proxy on the node, and the proxy has minimal dependencies. For demo installations, the proxy provides “bootstrap” mode, which automagically installs CRI Proxy on clusters installed with kubeadm, and possibly some other cluster setup tools, too.

(If we have time, I may also say a few words about hyper’s approach; they have something like CRI proxy built into their CRI implementation, which solves problem of running k8s components on the node, though it doesn’t help much with deployment problem.)

Lightning Talk: REST, RPC, and Brokered Messaging - Nathan Murthy, Tesla
Effective communication between distributed and heterogeneous components is essential for modern service-oriented architectures to work well. REST, RPC, and brokered messaging are the most popular communication styles for achieving this, but when is it appropriate for choosing one style over the other? A well-defined microservice architecture should be accompanied by a well-defined communications semantics. This talk draws on my personal experience defining these semantics for systems I’ve built at Tesla.
