Otomi turns any Kubernetes cluster into a PaaS for DevOps teams with paved roads from code to a running application

How Otomi helps

Developers - With easy self-service to let them focus on their apps only

Build OCI compliant images from application code and store them in a private registry
Deploy containerized workloads using a developer catalog with build-in or BYO golden path templates
Automatically update container images of workloads
Publicly expose applications
Get instant access to logs, metrics and traces
Configure network policies, response headers and CNAMEs
Manage secrets
Create private Git repositories and custom CI/CD pipelines

Operations - To setup a Kubernetes-based platform for developers and provide a paved road to production

Create your platform profile and deploy to any K8s
Onboard development teams in a comprehensive multi-tenant setup and make them self-serving
Get all the required capabilities in an integrated and automated way
Ensure governance with security policies
Implement zero-trust networking
Change the desired state of the platform based on Configuration-as-Code
Support multi- and hybrid cloud scenarios
Prevent cloud provider lock-in
Implement full observability
Create Golden path templates and offer them to development teams through a developer catalog

Check the video below to see how Otomi can be used as a self service portal for developers

Getting started

Helm

To install Otomi, make sure to have a K8s cluster running with at least:

Version 1.25, 1.26 or 1.27
A node pool with at least 8 vCPU and 16GB+ RAM (more resources might be required based on the activated capabilities)
Calico CNI installed (or any other CNI that supports K8s network policies)
A default storage class configured
When using the custom provider, make sure the K8s LoadBalancer Service created by Otomi can obtain an external IP (using a cloud load balancer or MetalLB)

NOTE: Install Otomi with DNS to unlock it's full potential. Check otomi.io for more info.

Add the Helm repository:

helm repo add otomi https://otomi.io/otomi-core
helm repo update

and then install the Helm chart:

helm install otomi otomi/otomi \
--set cluster.name=$CLUSTERNAME \
--set cluster.provider=$PROVIDER # use 'azure', 'aws', 'google', 'digitalocean', 'ovh', 'vultr', 'scaleway', 'civo', or 'custom' for any other cloud or onprem K8s

When the installer job is completed, follow the activation steps.

Platform architecture

Self-service portal and CLI

The self-service portal (Otomi Console) offers seamless user experience for developers and platform administrators. Platform administrators can use Otomi Console to enable and configure platform capabilities and onboard development teams. Developers can use Otomi Console to build images, deploy applications, expose services, configure CNAMEs, configure network policies and manage secrets. Otomi Console also provided direct and context aware access to platform capabilities like code repositories, registries, logs, metrics, traces, dashboards, etc. Next to the web based self-service, both developers and admins can start a Cloud Shell and run cli commands.

Desired state store

When Otomi is installed, the desired state of the platform is stored in the Desired State Store (the otomi/values repo in the local Git repository). Changes made through the Console will be reflected in the repo.

Golden templates catalog

The otomi/charts Git repo includes a set of build-in Helm charts that are used to create workloads in the Console. You can also add your own charts and offer them to the users of the platform.

Control plane

All changes made through the Console are validated by the control plane (otomi-api) and then committed in the state store. This will automatically trigger the platform to synchronize the desired state to the actual state of the platform.

Automation

The automation is used to synchronize desired state with the state of applications like Keycloak, Harbor and Gitea.

Capabilities

The platform offers a set of Kubernetes applications for all the required capabilities. Core applications are always installed, optional applications can be activated. When an application is activated, the application will be installed based on default configuration. Default configuration can be adjusted using the Console.

Core Applications (that are always installed):

Istio: The service mesh framework with end-to-end transit encryption
Keycloak: Identity and access management for modern applications and services
Cert Manager - Bring your own wildcard certificate or request one from Let's Encrypt
Nginx Ingress Controller: Ingress controller for Kubernetes
External DNS: Synchronize exposed ingresses with DNS providers
Tekton Pipeline: K8s-style resources for declaring CI/CD pipelines
Tekton Triggers: Trigger pipelines from event payloads
Tekton dashboard: Web-based UI for Tekton Pipelines and Tekton Triggers
Gitea: Self-hosted Git service

Optional Applications (that you can activate to compose your ideal platform):

Velero: Back up and restore your Kubernetes cluster resources and persistent volumes
Argo CD: Declarative continuous deployment
Knative: Deploy and manage serverless workloads
Kaniko: Build container images from a Dockerfile
Drone: Continuous integration platform built on Docker
Prometheus: Collecting container application metrics
Grafana: Visualize metrics, logs, and traces from multiple sources
Grafana Loki: Collecting container application logs
Harbor: Container image registry with role-based access control, image scanning, and image signing
HashiCorp Vault: Manage Secrets and Protect Sensitive Data
OPA/Gatekeeper: Policy-based control for cloud-native environments
Jaeger: End-to-end distributed tracing and monitor for complex distributed systems
Kiali: Observe Istio service mesh relations and connections
Minio: High performance Object Storage compatible with Amazon S3 cloud storage service
Trivy: Kubernetes-native security toolkit
Thanos: HA Prometheus setup with long term storage capabilities
Falco: Cloud Native Runtime Security
Opencost: Cost monitoring for Kubernetes
Paketo build packs: Cloud Native Buildpack implementations for popular programming language ecosystems
Cloudnative-pg: Open source operator designed to manage PostgreSQL workloads
Grafana Tempo: High-scale distributed tracing backend
OpenTelemetry: Instrument, generate, collect, and export telemetry data to help you analyze your software’s performance and behavior
