+# Bind charm
+
+A Juju charm deploying Bind, configurable to use a git repository for its configuration files.
+
+## Overview
+
+This is a k8s workload charm and can only be deployed to a Juju k8s cloud,
+attached to a controller using `juju add-k8s`.
+
+This charm is not currently ready for production due to issues with providing
+an egress to route TCP and UDP traffic to the pods. See:
+
+https://bugs.launchpad.net/charm-k8s-bind/+bug/1889746
+
+https://bugs.launchpad.net/juju/+bug/1889703
+
+## Details
+
+See config option descriptions in config.yaml.
+
+## Getting Started
+
+Notes for deploying a test setup locally using microk8s:
+
+    sudo snap install juju --classic
+    sudo snap install juju-wait --classic
+    sudo snap install microk8s --classic
+    sudo snap alias microk8s.kubectl kubectl
+    sudo snap install charmcraft
+    git clone https://git.launchpad.net/charm-k8s-bind
+    make bind.charm
+
+    microk8s.reset  # Warning! Clean slate!
+    microk8s.enable dns dashboard registry storage
+    microk8s.status --wait-ready
+    microk8s.config | juju add-k8s myk8s --client
+
+    # Build your Bind image
+    make build-image
+    docker push localhost:32000/bind
+    
+    juju bootstrap myk8s
+    juju add-model bind-test
+    juju deploy ./bind.charm --config bind_image_path=localhost:32000/bind:latest bind
+    juju wait
+    juju status
+
+Assuming you're using the image as built locally from this repo, the charm will
+deploy bind with its stock Ubuntu package configuration, which will forward all
+queries to root name servers.
+
+DNSSEC is also enabled by default.
+
+Custom config can be deployed by setting the `custom_config_repo` option to
+point to a Git repository containing a valid set of configuration files with
+which to populate the /etc/bind/ directory within the pod(s).
