Bind charm

A Juju charm deploying Bind, configurable to use a git repository for its configuration files.


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:


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

microk8s.reset  # Warning! Clean slate!
microk8s.enable dns dashboard registry storage
microk8s.status --wait-ready
microk8s.config | juju add-k8s myk8s --client

juju bootstrap myk8s
juju add-model bind-test

#1. Either deploy with the default image from Dockerhub:
juju deploy cs:~bind-charmers/bind

#2. Or optionally build your own image locally and deploy with that
sudo snap install charmcraft
git clone
cd charm-k8s-bind
make image-build
docker push localhost:32000/bind
juju deploy cs:~bind-charmers/bind --config bind_image_path=localhost:32000/bind:latest bind

juju wait
juju status

Assuming you're using the image from dockerhub, or an image built locally from this repo without changes, 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).


(string) Password to use for the configured image registry, if required
(string) The location of the image to use, e.g. "". This setting is required.
(string) Username to use for the configured image registry, if required
(string) YAML formatted map of container config keys & values. These are generally accessed from inside the image as environment variables. Use to configure customized Wordpress images. This configuration gets logged; use container_secrets for secrets.
(string) YAML formatted map of secrets. Works just like container_config, except that values should not be logged.
(string) Repository from which to populate /etc/bind/. If unset, bind will be deployed with the package defaults. e.g.
(string) Proxy address to set in the environment, e.g. Used to clone the configuration files from custom_config_repo, if set. If a username/password is required, they can be embedded in the proxy address e.g. http://username:password@ Traffic is expected to be HTTPS, but this will also work for HTTP.
