Switch to use DNS

When Otomi is installed with minimal values, a custom CA is generated and Otomi uses for host names. It is possible to switch from to using a DNS zone after installing Otomi initially without DNS. To switch from to a DNS zone, follow the instructions as described below.

Step 1: Enable external DNS flag

  • Sing in to Otomi Console with user otomi-admin
  • In the left menu, click on Setting under Platform
  • Click on Otomi
  • Enable the HasExternalDNS flag
  • Click on Submit

Step 2: Provide DNS values

  • In the left menu, click on DNS under Platform Settings
  • Provide the DNS zone name used by the Teams tom publish URLs on
  • Select your Provider
  • Provide the required values
  • Click on Submit

Step 3: Set cluster domain suffix

  • In the left menu, click on Cluster under Platform Settings
  • Provide the cluster Domain Suffix
  • Click on Submit

Step 4: Set DNS domain filter

  • Click on Apps under platform
  • Click on the External DNS app
  • Click on Values
  • Add the domain filter
  • Click on Submit

Step 5 (optional): Use Let's Encrypt

Let's encrypt requires a DNS zone. So if you would like to start using Let's Encrypt as a CA, now you can.

  • Click on Apps under platform
  • Click on the CertManager app
  • Click on values
  • Fill in an email address with a valid domain name
  • Under Issuer, click on Lets Encrypt

  • Click on Submit

Step 6: Deploy Changes

In the left menu, click on Deploy Changes

Wait for the Drone runner to finish:

kubectl get pod -n drone-pipelines -w

Step 7: Adjust the web hook in Gitea

Open Gitea and follow these steps:

First sign in to the Otomi Console using the new domain name: https://otomi.<your-domain-name>

  • Click on Apps under Platform
  • Click on the Gitea app
  • Sign in
  • Click on the otomi/values repository
  • Click Settings
  • Click Webhooks
  • Click on the existing webhook (https://drone.<ip-address>
  • Change the domain name in the target URL to your new domain name
  • Click Update Webhook

Step 8: Restart the Drone server and agent

Then run the following kubectl command:

kubectl delete pods -n team-admin -l app=drone

When both the Drone Agent and Server are back up, open the Drone app and follow these steps:

  • Click on Sign In on the 404 page
  • Click Continue
  • Click on Authorize Application
  • Complete the Drone registration
