in the cloud
one click: the provider's deploy form opens filled in, in your own account- koyeb
-
The form opens with CHANGE_ME for each value you supply: DELTAT_PASSWORD, DELTAT_HOST, DELTAT_PORT, DELTAT_DATABASE, DELTAT_USER, DELTAT_TLS, DELTAT_TLS_CA. Fill them in before you deploy.
Clients connect to the service's https://…koyeb.app address plus /mcp.
- azure
-
A Container Apps environment with one app per server, each with HTTPS ingress and one replica. The portal asks for each value you supply as a secure parameter; the deployment's outputs list the endpoints.
