<p class="MsoNormal">Hello, <o:p></o:p></p>
<div>
<p class="MsoNormal">I'm working on cloud-init generator as a part of airshipctl bootstrap isogen command.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">This cloud init will be used to deploy K8s on ephemeral node.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Following information is needed to set up ephemeral node:<o:p></o:p></p>
</div>
<div>
<ul type="disc">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
IP address<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">
Net mask <o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo1">

DNS server address<o:p></o:p></li></ul>
<div>
<p class="MsoNormal">There is no CRD/CR that actually has this information. For example BareMetalHost resource has IP and Netmask as a part of Status field (and determined dynamically by beremetal operator) and there is no info about Default GW and DNS.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">This actually leads us to the situation where we need to have IPAM (ip address management) operator and appropriate CRs/CRDs.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Unfortunately there is not much IPAM services that can act as K8s operator (I've found only one actually <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_inwinstack_ipam&d=DwMFaQ&c=LFYZ-o9_HUMeMTSQicvjIg&r=Bjzj_RciGLj21LnNXoD5dw&m=c8c5DfwYKVyHfFy7VcpEn5JOI4G1u4qxCaCy9cDsgAI&s=d7costGUiy-0u1vBkTFbV8Gf4-BIyHE3PGYKZ49NK7k&e=">https://github.com/inwinstack/ipam</a> and
it has limitations I guess). <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">As an alternative we have to implement IPAM as a part of Airship 2.0.<o:p></o:p></p>
