-## Building
+### Building Rancher Repositories

 Every repository should have a Makefile and can be built using the `make` command. The `make` targets are based on the scripts in the `/scripts` directory in the repository, and each target will use [Dapper](https://github.com/rancher/dapper) to run the target in an isolated environment. The `Dockerfile.dapper` will be used for this process, and includes all the necessary build tooling needed.

 The default target is `ci`, and will run `./scripts/validate`, `./scripts/build`, `./scripts/test` and `./scripts/package`. The resulting binaries of the build will be in `./build/bin` and are usually also packaged in a Docker image.

 A central advantage of traffic management in Istio is that it allows dynamic request routing. Some common applications for dynamic request routing include canary deployments and blue/green deployments. The two key resources in Istio traffic management are *virtual services* and *destination rules*.

 - [Virtual services](https://istio.io/docs/reference/config/networking/v1alpha3/virtual-service/) intercept and direct traffic to your Kubernetes services, allowing you to divide percentages of traffic from a request to different services. You can use them to define a set of routing rules to apply when a host is addressed.

 Resource quotas in Rancher include the same functionality as the [native version of Kubernetes](https://kubernetes.io/docs/concepts/policy/resource-quotas/). However, in Rancher, resource quotas have been extended so that you can apply them to projects.

 In a standard Kubernetes deployment, resource quotas are applied to individual namespaces. However, you cannot apply the quota to your namespaces simultaneously with a single action. Instead, the resource quota must be applied multiple times.

 Although the **Namespace Default Limit** propagates from the project to each namespace when created, in some cases, you may need to increase (or decrease) the quotas for a specific namespace. In this situation, you can override the default limits by editing the namespace.

 In the diagram below, the Rancher administrator has a resource quota in effect for their project. However, the administrator wants to override the namespace limits for `Namespace 3` so that it has more resources available. Therefore, the administrator [raises the namespace limits](../../manage-clusters/projects-and-namespaces.md) for `Namespace 3` so that the namespace can access more resources.

 Rancher simplifies the creation of clusters by allowing you to create them through the Rancher UI rather than more complex alternatives. Rancher provides multiple options for launching a cluster. Use the option that best fits your use case.

 This section assumes a basic familiarity with Docker and Kubernetes. For a brief explanation of how Kubernetes components work together, refer to the [concepts](../reference-guides/kubernetes-concepts.md) page.

 You can have Rancher launch a Kubernetes cluster using any nodes you want. When Rancher deploys Kubernetes onto these nodes, it uses [Rancher Kubernetes Engine](https://rancher.com/docs/rke/latest/en/) (RKE), which is Rancher's own lightweight Kubernetes installer. It can launch Kubernetes on any computers, including:

 In situations where several teams share a cluster, one team may overconsume the resources available: CPU, memory, storage, services, Kubernetes objects like pods or secrets, and so on.  To prevent this overconsumption, you can apply a _resource quota_, which is a Rancher feature that limits the resources available to a project or namespace.

 This page is a how-to guide for creating resource quotas in existing projects.

 The new user guides are designed to guide beginners, or the everyday users of Rancher, through a series of steps to learn how to do something. The goal is that the user will be able to learn how to complete tasks by using easy-to-follow, meaningful, and repeatable directions. These guides will assist users to do work to then get the promised results immediately.
