esmet / teleproxy Goto Github PK

This repository contains the Edge ToolKit, or ETK for short. The ETK is a collection of binaries and golang libraries for managing requests that that flow into, out of, or within Kubernetes-based cloud native applications.

Commands:

• edgectl - CLI for controlling the traffic into, out of, or within a Kubernetes cluster
• teleproxy - connect locally running code to a remote Kubernetes cluster
• watt - trigger actions when Kubernetes and/or consul resources are updated
• kubeapply - apply Kubernetes manifests with templating, docker builds, and feedback
• k3sctl - run/manage a lightweight local Kubernetes cluster and docker registry for testing
• kubestatus - display and update the status of arbitrary Kubernetes resources

Libraries:

• supervisor - a library (or very lightweight framework) for helping with error handling, startup/shutdown order, and guaranteed resource cleanup amongst groups of related goroutines
• k8s - an easy-to-use facade around the client-go library
• dtest - testing related utilities

See CHANGELOG for notes on the current release.

This repository follows the standard golang package layout.

You will find the source code for the binary commands at <repo>/cmd/<name>/.... The main function for each command should be in a file named main.go within the command directory, e.g. <repo>/cmd/<name>/main.go.

Public packages can be found at <repo>/pkg/<name>/..., and internal packages can be found at <repo>/internal/pkg/<name>/....

Use make check and make build for running formal test and builds. You can use make help to find other useful targets.

The fastest way to install any command from source, e.g. for inner loop development is to run go install ./cmd/<name>/....

The fastest way to run tests is to run go test ./<path>/...

The tests require a Kubernetes cluster and a docker registry to run. By default these are spun up locally on demand. You can also supply your own cluster and/or registry.

These are left running in between test runs for performance. If you want a fully clean test run, you can use docker ps and docker kill to clean these up. You can also run go install ./cmd/k3sctl/... to get the k3sctl command and use k3sctl up and k3sctl down to control these containers. Use the k3sctl help command to find other useful commands, e.g. you can use k3sctl config -o /tmp/k3s.yaml to get a kubeconfig for kusing kubectl against the testing cluster.

Use the DTEST_REGISTRY environment variable to make the tests use a given docker registry for testing. You will need to be authenticated and have permission to push to whatever registry you supply.

Use the DTEST_KUBECONFIG environment variable to make the tests use a particular Kubernetes cluster for testing. Note that the tests may be destructive, so make sure you use a suitable cluster. This cluster will need to be able to pull from whatever registry you supply.
