# Add a new transport

Starting with PDK 1.12.0 there is the `pdk new transport` command, that you can use to create the base files for your new transport:

Next, we'll active a few future defaults. In the `hue_workshop` directory, create a file called `.sync.yml` and paste the following:

```
# .sync.yml
---
Gemfile:
  optional:
    ':development':
      - gem: 'puppet-resource_api'
      - gem: 'faraday'
      - gem: 'rspec-json_expectations'
spec/spec_helper.rb:
  mock_with: ':rspec'
```

Run `pdk update` in the module's directory to deploy the changes in the module:

```
david@davids:~/tmp/hue_workshop$ pdk update --force
pdk (INFO): Updating david-hue_workshop using the default template, from 1.10.0 to 1.10.0

----------Files to be modified----------
Gemfile
spec/spec_helper.rb

----------------------------------------

You can find a report of differences in update_report.txt.

Do you want to continue and make these changes to your module? Yes

------------Update completed------------

2 files modified.

david@davids:~/tmp/hue_workshop$
```

Then, create the actual transport:

```
david@davids:~/tmp/hue$ pdk new transport hue
pdk (INFO): Creating '/home/david/tmp/hue/lib/puppet/transport/hue.rb' from template.
pdk (INFO): Creating '/home/david/tmp/hue/lib/puppet/transport/schema/hue.rb' from template.
pdk (INFO): Creating '/home/david/tmp/hue/lib/puppet/util/network_device/hue/device.rb' from template.
pdk (INFO): Creating '/home/david/tmp/hue/spec/unit/puppet/transport/hue_spec.rb' from template.
pdk (INFO): Creating '/home/david/tmp/hue/spec/unit/puppet/transport/schema/hue_spec.rb' from template.
david@davids:~/tmp/hue$
```

## Checkpoint

To validate your new module and transport, run `pdk validate --parallel` and `pdk test unit`:

```
david@davids:~/tmp/hue$ pdk validate --parallel
pdk (INFO): Running all available validators...

```

If you're working with a version control system, now would be a good time to make your first commit and store the boilerplate code, and then you can revisit the changes you made later. For example:

```
david@davids:~/tmp/hue$ git init
Initialized empty Git repository in ~/tmp/hue/.git/
david@davids:~/tmp/hue$ git add -A
david@davids:~/tmp/hue$ git commit -m 'initial commit'

## Next up

Now that you have everything ready, you'll [implement the transport](./05-implementing-the-transport.md).
