[Adeniji (Oluwasogo) Daniel @dan_adeniji]

I am a DevOps & Cloud Engineer bridging the gap between Hardware logic and Cloud Infrastructure.

I don’t just "run servers"—I build systems that save money and time.

A short thread on my journey and what I’m building. 🧵👇

@gdgabeokuta When is Devfest ABK? 🤲

[Adeniji (Oluwasogo) Daniel @dan_adeniji]

@LyceumCloud @govardhana_mk I agree with this. I actually learnt more while debugging and fixing stuffs. Doing projects at each stage helps a lot.

∟ 📂 Build and push Docker images from pipeline
∟ 📂 Basic CD to a test VM or test server

∟ 📂 Phase 5 (Weeks 17–20) Infrastructure as Code
∟ 📂 Terraform basics (providers, resources)
∟ 📂 Remote state and state locking
∟ 📂 Variables, outputs and modules
∟ 📂 Use Terraform to create VPC, subnets, EC2/VMs
∟ 📂 Store Terraform in Git and run via pipeline

∟ 📂 Phase 6 (Weeks 21–26) Kubernetes Fundamentals
∟ 📂 Core objects (Pods, Deployments, ReplicaSets)
∟ 📂 Services (ClusterIP, NodePort, LoadBalancer)
∟ 📂 ConfigMaps and Secrets
∟ 📂 Ingress basics and DNS
∟ 📂 kubectl use and basic troubleshooting

∟ 📂 Phase 7 (Weeks 27–32) Kubernetes in Cloud
∟ 📂 Managed cluster (EKS / AKS / GKE) setup
∟ 📂 Node groups and autoscaling basics
∟ 📂 Storage classes and PersistentVolumeClaims
∟ 📂 Namespaces, RBAC and basic multi-tenant setup
∟ 📂 Rolling updates and rollbacks

∟ 📂 Phase 8 (Weeks 33–36) DevOps Operations
∟ 📂 Logging setup (app + cluster logs)
∟ 📂 Basic metrics and dashboards
∟ 📂 Alerts on failures and high usage
∟ 📂 Backup and restore for workloads
∟ 📂 Simple SLO thinking (availability, latency)

∟ 📂 Phase 9 (Weeks 37–40) DevOps Security
∟ 📂 Cloud security basics (IAM hygiene, least privilege)
∟ 📂 Network security (SG/NSG, firewall rules)
∟ 📂 Image scanning and dependency scanning
∟ 📂 Kubernetes security basics (RBAC, Pod Security)
∟ 📂 Secrets management (cloud KMS, Vault, SealedSecrets)

∟ 📂 Phase 10 (Weeks 41–52) Real Projects & Portfolio
∟ 📂 Build a full infra with Terraform in cloud
∟ 📂 Deploy a microservice app on Kubernetes
∟ 📂 Wire CI/CD to build, test and deploy to cluster
∟ 📂 Add logging, metrics and alerts
∟ 📂 Break things on purpose and fix them
∟ 📂 Document everything on GitHub and LinkedIn

My current toolkit for solving problems:

Cloud: Azure, AWS,
Containers: Kubernetes (AKS), Docker
IaC: Terraform, Ansible, Bicep
Scripting: Python, Bash

I automate everything I have to do more than twice.

How Terraform works 🔥🔥

[Adeniji (Oluwasogo) Daniel @dan_adeniji]

@techyoutbe I just started using terraform this year and I'm in love with IAC already. Avoiding redundancy and scalability 😊😇...also collaboration (using remote state) on terraform, just got me hooked in 😇
