* Fix for kube-dns returns NXDOMAIN when not yet synced with apiserver.
    * Don't generate empty record for externalName service.
    * Add validation for upstreamNameserver port.
    * Update go version to 1.9.3.

# ADR-0001 - Use Architectural Decision Records

## Status

- ACCEPTED on 2023-12-01

## Context

In a distributed team with many subteams, the best solution to communicate decisions is to use a format accessible by everyone in charge of development.

We use *Specification* and *Discovery* documents stored in Google Drive, but they present some downsides:

    * - Fix for kube-dns returns NXDOMAIN when not yet synced with apiserver.
    * - Don't generate empty record for externalName service.
    * - Add validation for upstreamNameserver port.
    * - Update go version to 1.9.3.
