Course schedule
1 Fundamentals
- Application in 12 factors, integration, continuous deployment (CI/CD), Cloud-native applications.
- SaaS, PaaS, IaaS, object and block storage. Private, public, hybrid cloud: Problem of lock-in.
- Elastic architecture, Cattle versus Pet, Infrastructure as Code.
- Existing tools (Terraform, Ansible). Bebefit of containers versus Virtual Machines.
- CaaS in an enterprise: interoperability, Devops organization, digital transformation.
- Bimodal IT and DevOps.
Demonstration
Cloud IaaS: Digital Ocean, MS-Azure.
2 Docker
- Basic concepts: Immutability, image, layers, registry, network and storage issues.
- Automation with Dockerfile/docker-compose, integration with Github, Jenkins, DockerHub.
- Expected benefits: Reproducibility, manageability.
- Benefits in terms of elasticity, agility, upgradability.
- Impacts on development and infrastructure teams.
Demonstration
Building, modifying, and publishing Docker images.
3 Kubernetes, container orchestrator.
- Master/Workers nodes, concepts of Pods, service, different types of Ingress Controller.
- Storage: stateful, stateless, shared (NFS, GlusterFS, CEPH, rook).
- Configuration management. Using Jobs and DaemonSets.
- Internal component (etcd, kubelet, kube-dns, kube-proxy, apiserver), complementary (Helm/Tiller, envoy, side-car proxy).
- Service Discovery/Mesh (Istio), calico, cilium.
Demonstration
Building a cluster and deploying a complete stack (including Wordpress).
4 Container as a Service (CaaS)
- Standardization: OCI, CNCF, CNI, CSI, CRI.
- Cloud/Managed solutions: Amazon AWS ECS and EKS and Fargate, Google GCP, Microsoft Azure, DigitalOcean.
- Most common On-Premises solutions: Docker DataCenter, Rancher, RedHat OpenShift.
- Evolution to Serverless.
5 Security of CaaS/Kubernetes/Docker
- Infrastructure security: partitioning, RBAC, vault/secret, logs.
- Securing containers (runtime): Seccomp, SElinux, Apparmor, Linux Capabilities, PodSecurityPolicies.
- Securing the Supply Chain: registry, notary, compliance check
Demonstration
Specific attacks, L3/L4/L7 micro-segmentation. Scanning an image’s vulnerabilities, container hardening, exporting real-time logs in Splunk.
