open-hardware-github-kubernetes Kubernetes is a popular open source container orchestration system that automates application deployments, scaling, and managing. It is one of the most popular container solutions available today. The list below contains a list of Kubernetes DevOps tools to help you get the most out of its capabilities. Kube Cluster Deployment Tools. 1. Amazon EKS. Amazon Elastic Container Service is a Kubernetes DevOps tool that allows users to manage and scale their containerized applications and simplify deployments using Kubernetes. Amazon EKS can run Kubernetes without having to operate on your own Kubern. GitHub actions are a new CI/CD service from GitHub. Actions are simple workflows configured as Yaml files which run configurable steps of code based on GitHub events. Since they are baked into GitHub, they reduce significantly the overhead in getting a CI/CD pipeline setup. This tutorial will go through the basics of GitHub actions as well as deploying to Kubernetes using a pre-built Helm action. For this guide we’re assuming some basic knowledge of Kubernetes and Helm but you’ll probably be able to follow along regardless. Let’s get started with some of the basic concepts of GitHub actions. T. The Kubernetes executor. GitLab Runner can use Kubernetes to run builds on a Kubernetes cluster. This is possible with the use of the Kubernetes executor. The Kubernetes executor, when used with GitLab CI, connects to the Kubernetes API in the cluster creating a Pod for each GitLab CI Job. This Pod is made up of, at the very least, a build container, a helper container, and an additional container for each service defined in www.- or www.- files.

Open Infrastructure Manager OIM is an open source project which simplifies the integration of storage and network accelerator hardware into cloud environments like Kubernetes, Mesos and OpenStack. It provides the control plane and plugins to make network kubfrnetes available via the Storage Performance Development Kit SPDK daemon, both with hardware manager and without.

Because SPDK runs in user space and uses polling extensively, it achieves much better performance and lower latency than comparable kernel drivers. OIM components may be on different networks. This is important for storage accelerator hardware where the kernel on the main compute node only sees a standard PCI device, like a SCSI controller, without a way to issue special commands through that interface.

In such a setup, control of the accelerator hardware has to go through hafdware proxy. In OIM, this proxy is provided by the control plane where all accelerator hardware is registered. This control plane is independent of any particular cloud environment. The resulting binaries do not depend on any other userspace library and thus work on different distributions. For testing purposes the OIM registry can be run with a single process storing all data in memory.

A open hardware github kubernetes environment is expected to use etcd with multiple OIM registry instances as frontend to increase scalability. Communication with the control plane is limited to short-lived, infrequent connections. Provisioning new block volumes is specific to the storage provider and therefore open hardware github kubernetes additional components that know how to control certain storage providers.

The main goal for OIM itself is to make already provisioned network attached block volumes available as local block devices. Depending on the cloud environment, either the block devices or filesystems mounted on top of the devices will then be used by applications.

Operation as part of Kubernetes is open hardware github kubernetes tested. These parameters are defined by the third-party open hardware github kubernetes and not standardized, therefore compile-time extensions of the OIM CSI driver are needed to support other third-party drivers - see ceph-csi.

All supported drivers are described below. Each accelerator hardware instance has its own controller. They get identified by an ID that is unique for all instances connected to the same control plane. When deploying one OIM registry per cluster with unique host names inside that cluster, the host name can be used as hardwware ID. More complex deployment scenarios are still possible.

This is relevant when clients and the controllers are on different networks or open hardware github kubernetes the clients do not know the network address of the controllers. Conceptually the database stores string values with a set of string path elements as key. All strings are UTF-8 encoded. Leading and trailing slashes are ignored and repeated slashes are treated like a single slash.

Some keys have a special meaning and are used by OIM itself, while the others can be used to store arbitrary meta information kuberndtes an accelerator. The special keys are:. There is one OIM controller per accelerator hardware device.

The OIM controller responds open hardware github kubernetes requests that control the operation of the hardware. If provided with the necessary information which controller ID to use, registry endpoint, its own external endpointthe OIM controller can register the hardware with the OIM registry on startup and at regular intervals, Open Hardware Stores Today Github to recover from a potential loss of the registry DB.

But this is optional. It uses that controller to map or unmap volumes. In the future, dynamically attaching new virtio block controllers for each new volume might also be supported.

All communication is protected by mutual TLS. Both client and server must identify themselves and the certificate they present must be open hardware github kubernetes. The common name in each certificate is used to identify the different components and authorizes certain operations.

The following common names have a special gjthub. All components trust the registry when it presents a component. The registry accepts connections only from trusted peers and in addition, checks for user. Connections from the registry proxy to the controller expect the controller to have controller. The OIM controller therefore only gituub to check that incoming commands come from the registry and can rely on the registry to ensure that the command comes from the right OIM CSI driver.

Likewise, the registry protects secrets embedded in commands by verifying the identity of the controller it connects to and detects configuration mistakes like an address that points to the wrong controller.

Certificates and keys get loaded anew for each connection attempt. Testing will need additional packages, which will be described in the corresponding open hardware github kubernetes below. When moving beyond simple building, external resources like images from Clear Linux or Docker registries are needed.

In a corporate environment where proxies have to be used for HTTP, the following environment variables will be used to configure proxy usage:. When changing proxy settings later, that file has to be updated manually see below for instructions for starting and logging into the virtual machine or the open hardware github kubernetes must be created again oepn a make clean. Simple tests can be run with makego test or dlv test and don't have kubernees additional dependencies:.

It only runs tests anew open hardware github kubernetes the Go source code was modified since the last test run. When tests need to be run again because the external resources QEMU image, SPDK or the test configuration variables changed, then one has to clean the cache first or use a special make target:.

The version must be v2. For networking, the ip oprn from the iproute2 package must be installed. The following command must be run once after booting the open hardware github kubernetes machine and before starting the virtual machine:.

This configures four tap devices for use by the current user. At the moment, the test setup uses:. It is possible to configure this by creating one or more files ending in.

For all supported options, see test-config. KVM must be enabled and the user must be allowed to use it. Usually this is done by adding the user to the kuberneets group.

The message about missing KVM hardware support comes from inside the virtual machine and indicates that nested KVM is not enabled. This can be ignored because it is not needed.

Testing with QEMU can be enabled in several different ways. When using make, these variables can be set in the open hardware github kubernetes or via the make parameters. The clear-kvm images are prepared automatically by the Makefile. By default, four different images are prepared, each pre-configured with its own hostname and with network settings for the corresponding tap device.

Running SPDK is not possible without root privileges. Mounting open hardware github kubernetes also requires root privileges. The impact has been minimized as much as possible by running most code as normal user in the developer's environment and only invoking some operations via sudo. The build machine must be prepared to allow this, huge pages must be set up so that normal users can hardwars them, and nbd must be available:.

Building SPDK depends on additional packages. SPDK provides a shell script for installing those. In OIM, that script can be invoked as:. However, the script only covers the dependencies of the core functionality in SPDK. For Ceph RBD support, librbd-dev or kubernftes similar package also needs to be installed.

SPDK will be built automatically from known-good source code bundled in the repository when selecting it with:. The driver image will be built automatically by the Makefile when running the tests. It can also be built separately with:. In addition to enabling additional tests individually as explained above, it is also possible to enable everything at once with:.

Once it completes, everything is ready for interactive use via kubectl inside the virtual machine. Only the first node in the cluster is connected to a virtio-scsi device provided by the SPDK daemon on the host, so only that node can use hardware accelerated storage. It has been labeled with intel. There are open hardware github kubernetes. The original ceph-csi rbdplugin runs on the rest of the nodes.

Cluster-wide operations like provisioning are handled by the StatefulSet which contains external-provisionerexternal-attacher and the original ceph-csi rbdplugin:. This is just an example. Administrators of a cluster must ensure that they choose key lengths and algorithms of sufficient strength for their purposes and manage certificate distribution.

They open hardware github kubernetes be used to test man-in-the-middle attacks. Securely distributing just the required certificate to the OIM CSI driver on each node is not possible with open hardware github kubernetes Kubernetes primitives.

But the builtin mechanism, Kubernetes secrets, can only provide the same secret to all pods in a deployment. The demo cluster therefore makes the secret keys for all nodes available on all nodes and then points the OIM CSI driver to the right files with a command line parameter.

In command line parameters it is possible to embed the node name. A production deployment can improve upon that by using some other key delivery mechanism, like for example Vault.
