### Vault items creation and cookbook attribute settings (with default attributes)

#### CA certificates

- create vault items.

```text
$ ruby -rjson -e 'puts JSON.generate({"public" => File.read("grid_ca.prod.crt")})' \
> > ~/tmp/grid_ca.prod.crt.json

$ knife vault create ca_certs grid_ca.prod \
> --json ~/tmp/grid_ca.prod.crt.json
```

- add cookbook attributes.

```ruby
override_attributes(
  'ssl_cert' => {
    'ca_names' => [
      'grid_ca',
      # ...
    ],
  },
)
```

#### CA public keys (0.2.0 or later)

- create vault items.

```text
$ ruby -rjson -e 'puts JSON.generate({"public" => File.read("grid_ssh_ca.prod.pub")})' \
> > ~/tmp/grid_ssh_ca.prod.pub.json

$ knife vault create ca_pubkeys grid_ssh_ca.prod \
> --json ~/tmp/grid_ssh_ca.prod.pub.json
```

- add cookbook attributes.

```ruby
override_attributes(
  'ssl_cert' => {
    'ca_pubkey_names' => [
      'grid_ssh_ca',
      # ...
    ],
  },
)
```

#### SSH-CA KRL (0.3.0 or later)

- create vault items.

```text
$ ruby -rjson -e 'puts JSON.generate({"public" => File.read("grid_ssh_ca.prod.krl")})' \
> > ~/tmp/grid_ssh_ca.prod.krl.json

$ knife vault create ssh_ca_krls grid_ssh_ca.prod \
> --json ~/tmp/grid_ssh_ca.prod.krl.json
```

- add cookbook attributes.

```ruby
override_attributes(
  'ssl_cert' => {
    'ssh_ca_krl_name' => 'grid_ssh_ca',
  },
)
```

#### SSL server keys and certificates

- create vault items.

```text
$ ruby -rjson -e 'puts JSON.generate({"private" => File.read("node_example_com.prod.key")})' \
> > ~/tmp/node_example_com.prod.key.json

$ knife vault create ssl_server_keys node.example.com.prod \
> --json ~/tmp/node_example_com.prod.key.json

$ ruby -rjson -e 'puts JSON.generate({"public" => File.read("node_example_com.prod.crt")})' \
> > ~/tmp/node_example_com.prod.crt.json

$ knife vault create ssl_server_certs node.example.com.prod \
> --json ~/tmp/node_example_com.prod.crt.json
```

- add cookbook attributes

```ruby
override_attributes(
  'ssl_cert' => {
    'common_names' => [
      'node.example.com',
      # ...
    ],
  },
)
```

### References of deployed key and certificate file paths (with default attributes)

- `node['ssl_cert']["#{ca}_cert_path"]` - e.g. `node['ssl_cert']['grid_ca_cert_path']`
- `node['ssl_cert']["#{ca}_pubkey_path"]` - e.g. `node['ssl_cert']['grid_ssh_ca_pubkey_path']`
- `node['ssl_cert']["#{ca}_krl_path"]` - e.g. `node['ssl_cert']['grid_ssh_ca_krl_path']`
- `node['ssl_cert']["#{undotted_cn}_key_path"]` - e.g. `node['ssl_cert']['node_example_com_key_path']`
- `node['ssl_cert']["#{undotted_cn}_cert_path"]` - e.g. `node['ssl_cert']['node_example_com_cert_path']`
