Configurations

Server and cluster configuration management with Ansible and Kubernetes.

What are Configurations?

Configurations in ops0 let you manage server settings and Kubernetes deployments using Ansible playbooks and Kubernetes manifests. Unlike Infrastructure as Code (which provisions cloud resources), Configurations handle what runs on your infrastructure.

Configuration Types

Ansible

Automate server configuration with playbooks. SSH-based, agentless, idempotent.

Kubernetes

Deploy containerized workloads with YAML manifests. Declarative, self-healing.

How It Works

Create Project

Choose Ansible or Kubernetes type.

Write Code

Use AI-assisted editor to create playbooks or manifests.

Validate

Lint and syntax check your code.

Deploy

Run with dry-run first, then apply to targets.

Use Cases

Use Case	Tool	Example
Web server setup	Ansible	Install nginx, configure SSL, enable gzip
Database installation	Ansible	Install PostgreSQL, create databases, set up replication
User management	Ansible	Create users, manage SSH keys, configure sudo
Microservice deployment	Kubernetes	Deploy containers with replicas and autoscaling
Secret management	Kubernetes	Store credentials in Secrets, mount to pods
Load balancing	Kubernetes	Expose services via Ingress with SSL termination

Ansible vs Kubernetes

Aspect	Ansible	Kubernetes
Target	Servers (VMs, bare metal)	Kubernetes clusters
Connection	SSH	Kubernetes API
Format	YAML playbooks	YAML manifests
Execution	Push-based, run on demand	Declarative, controller-based
Best for	Server configuration	Container orchestration

Task Status Colors

When deployments run, tasks show colored status indicators:

Status	Color	Meaning
OK	Green	No change needed
Changed	Yellow	Resource was modified
Failed	Red	Task encountered an error
Skipped	Cyan	Conditional skip
Unreachable	Dark Red	No connection to host

Quick Start

Create a Project

Start a new Ansible or Kubernetes configuration project

Use the Editor

Write playbooks and manifests with AI assistance

Deploy Configurations

Run playbooks on servers or apply manifests to clusters

Kubernetes Deep Dive

Monitor clusters, incidents, and resource graphs

Example: Configure Web Servers with Ansible

Here's a typical workflow for configuring nginx on a group of web servers:

1. Create Project

Name:        nginx-webserver-setup
Type:        Ansible
Target:      Server Group: production-web (4 servers)

2. Write Playbook with AI

Prompt: "Install nginx with SSL using Let's Encrypt, enable gzip, add security headers"

Produced site.yml:

---
- name: Configure secure nginx web server
  hosts: webservers
  become: yes
  vars_files:
    - vars/main.yml

  roles:
    - nginx
    - certbot

3. Validate

✓ ansible-lint passed
✓ Syntax check passed
✓ 0 errors, 0 warnings

4. Deploy (Dry Run First)
