* Getting started with a [basic octoDNS configuration](basic/) - new to octoDNS
this is the place to start. It'll walk you through the main pieces of DNS IaC
with octoDNS including the process of planning and applying changes.
### Running PowerDNS
If you'd like to play around with running the examples in this directory
interactively you'll need a target for pushing data to.
[octodns-powerdns](https://github.com/octodns/octodns-powerdns) is the best
stand-alone option for this and the examples directory makes extensive use of
it. There is a [docker-compose.yml](docker-compose.yml) file that should get a
fully functional copy of PowerDNS backed my MySQL with the API enabled along
with other relivant functionality. For any of the examples that refer to the
local PowerDNS instance the following instructions below should get it up and
running.
1. If you haven't already [install docker compose](https://docs.docker.com/compose/install/)
1. If you don't already have a copy of octoDNS checked out run `git clone https://github.com/octodns/octodns.git`
1. In a seperate terminal window or tab
1. cd into the examples directory `cd octodns/examples`
1. Run docker-compose up `docker-compose up`, this will start up MySQL and PowerDNS running them in the foreground with their logs printing to the terminal

## Populating some data that we can later dump
We need zone & record data in our provider in order to have something to dump
out into a YAML config, thus our first step is to populate PowerDNS. This is
just to have something to work with the the actual process that begins in the
next step. It's not something you'd normally do when migrating to octoDNS.
Step 0 is to get a local PowerDNS instance running.
Check out out [Running PowerDNS](../README.md#running-powerdns) for info on
starting that up. Once you've done that run the following. You can ignore the
output and move on to the next step.

[dynamic-zone-config](../dynamic-zone-config) for details on how to explicitly
list your zones in the config file.
The quoted * below is what tells octodns-dump to dynamically source the list of
zones and dump config files for all of them. If you would only like to dump a
specific zone you can replace it with the zone name, e.g. `my-domain.com.`,
making sure to include the trailing `.`
We first tell octodns-dump where to find our config file. We then tell it that
we want to use the output provider defined in that file named `config` rather
than having a default one auto-created. This would allow us to customize the
details of the provider, e.g. things like the `default_ttl`.
We'll then tell dump where we would like it to write our zone files, in this
case we want it to put them into `config` provider's directory `./config`.
The quoted * tells octodns-dump to dynamically source the list of zones and
dump config files for all of them. If you would only like to dump a specific
zone you can replace it with the zone name, e.g. `my-domain.com.`, making sure
to include the trailing `.`
The final argument passed to `octodns-dump` is the source of data you'd like to
dump. Here that's our existing provider `powerdns`.
Note that if you're previously run other examples you may see entries in the
log output for those zones in addition to the ones we populated for this
exercise. They shouldn't cause any problems and can be ignored.

With `--lenient` we now see a warning about the validation problems, but
octoDNS does its best to continue anyway.
## Examining the results
We can now take a look in the config/ directory to see the created zone files
along side our main config.
```console
(env) coho:migrating-to-octodns ross$ ls -1 config/
my-domain.com.yaml
(env) ls -1 config/
my-dumpable.com.yaml
octodns.yaml
unused-domain.io.yaml
unused-dumpable.com.yaml
```
If you open up the my-domain.com.yaml file you'll note that the root NS record values are missing
their trailing `.`s. octoDNS has done its best to dump things as they currently
are in the provider. That means that if you tried to generate a plan with
`octodns-sync` now it would fail b/c the configuration doesn't follow best
practices.
Again note if you're run through other examples you may see more files for
their zones in this directory. They can be ignored for the purpose of the
example, but they will be imported and managed nonetheless.
If you open up the my-dumpable.com.yaml file you'll note that the SSHFP
record's values have 42 and 43 for their algorithm field.
With those values if you tried to generate a plan with `octodns-sync` now it
would fail with validation errors.
When migrating it's recommended to make as few changes to your config as
possible initially, that is you want to bring the setup as-is under octoDNS
management and avoid churn as much as possible. This is the safest approach,
change as little as possible and incrementally work towards having a fully
managed and compliant/best practice config.
management. This is the safest approach, change as little as possible and
incrementally work towards having a fully managed and compliant/best practice
config.
So for now we'll enable `lenient` on the root NS record. For more details on
see the [lenience](../lenience/) example.
So for now we'll enable `lenient` on the SSHFP record by editing
my-dumpable.com.yaml adding `octodns.lenient = true` as shown below. For more

type: CNAME
# CNAMEs can only have a single value so they require `value` to be used. As a
# best practice the target name must end with a `.` If you have a specific
# case where you need to omit the `.`, or other enforced best practices, see
# the lenience example for more information.

# This is an example of a record with a `.` in it's name, it would result for a
# TXT query of NADCBiQKBgQ._companyname.my-domain.com. This specific example is
# another commonly required proof of overship record.
