Build a Self-Service App Hosting Platform with Dokploy
This blueprint describes how to deploy Dokploy as a lightweight, highly-available application platform on Open Telekom Cloud. The setup uses Docker Swarm for container orchestration and Traefik as the ingress controller, combined with an Elastic Load Balancer (ELB) for TLS termination and secure external access. The architecture runs on multiple Elastic Cloud Servers (ECS) in a high-availability configuration, with a bastion host for administrative access and a NAT gateway for outbound connectivity.
Building Highly Available Web Server Clusters with Keepalived
Virtual IP addresses are used for active and standby switchover of ECSs to achieve high availability. This way if one ECS goes down for some reason, the other one can take over and services continue uninterrupted. This article uses CentOS Stream release 9 ECSs as an example to describe how to set up highly available web server clusters using Keepalived and Nginx.
Configuring Private Domain Names for ECSs
If one of your ECSs is not working normally and you need to use the backup ECS to handle requests, but you have not configured private zones for the two ECSs, you need to change the private IP address in the code for the faulty ECS. This will interrupt your services and cause you to publish your website again, which is time- and labor-consuming.
Deploy Applications with Dokploy
The final part of this blueprint describes how to deploy highly available user workloads with Dokploy on Open Telekom Cloud, positioning it as an open-source alternative to platforms such as Vercel, Netlify, Azure App Services and AWS Elastic Beanstalk.
Deploy Dokploy on ECS
The first part of the blueprint explains how to deploy a highly available Dokploy platform on a fleet of Elastic Cloud Servers (ECS). It covers the configuration of the required Open Telekom Cloud services, including VPC, NAT Gateway, Elastic Load Balancer, RDS, and DCS,
Deploying Containers that Can Communicate with Each Other on ECSs
You can deploy containers, that are not provided by Open Telekom Cloud's Container Services (CCE or CCI), on Elastic Cloud Servers (ECS) and enable the containers on different ECSs, but in the same subnet, to communicate with each other.
From ECS-hosted MongoDB to DDS
DRS helps you migrate data from MongoDB databases on ECSs to DDS instances on the current cloud. With DRS, you can migrate databases online with zero downtime and your services and databases can remain operational during migration.
Using RDS for PostgreSQL to Set Up Umami on ECS
In this blueprint we are going to set up Umami on Open Telekom Cloud leveraging an Elastic Cloud Server (ECS), while using Relational Database Service (RDS) for PostgreSQL to manage the database.
Zone-redundant NFS Server
The main target of this blueprint is to provide a zone-redundant NFS Server with the option to perform a failover. We are going to use ECS, EVS and Storage Disaster Recovery Service of Open Telekom Cloud for that. Additionally we will cover operational tasks like extending the size of the NFS Share.
