VaaS integration based on a hook mechanic. An app is usually registered with VaaS once it becomes healthy and deregistered before termination.

Task’s desired address (--addr) and port (--port, -p) will be (de)registered under a director provided by --director. A VaaS API url needs to be provided (--vaas-url or VAAS_URL) along with an API user (--user, -u) and secret key (--key, -k). If task needs a defined weight it can be provided with --weight at registration. Registered backend can be tagged as a canary using --canary.

Examples:

export VAAS_URL="http://vaas.example.com/api"
export VAAS_USER="admin"
export VAAS_KEY="secret-key"
vaas-hook --debug --addr=192.168.0.10 --port 80 --director=hook-test register cli --weight 1 --dc dc1
vaas-hook --debug --addr=192.168.0.10 --port 80 --director=hook-test deregister cli

This hook can also read a Kubernetes environment and access annotations via it's Pod API. All the available annotations can be viewed in k8s/pod.go. Action names and debug flag still needs to be provided via command line. A working example can be found in examples/service-with-lifecycle.yaml

Examples:

vaas-hook --debug register k8s
vaas-hook --debug deregister k8s

To run executor tests locally you need following tools installed:

• Go 1.9+
• Make
• Linux or Docker

vaas-registration hook offers a debug mode that provide extended logging and capabilities during runtime. To enable debug mode add --debug flag to the command or set VAAS_HOOK_DEBUG environment variable to true.

To build this project, just execute the following command in project root folder:

$ make

It will run tests and create a binary and a ZIP package for release purposes.
