8. Backup and Disaster Recovery:
• Implement regular backups of critical data and system configurations to ensure data integrity and availability in case of data loss or system failure.
• Store backups securely off-site or in an isolated network segment to prevent unauthorized access and protect against ransomware attacks.
• Test backup and recovery procedures periodically to verify data recoverability and minimize downtime in the event of a disaster.
9. Security Compliance and Auditing:
• Adhere to industry best practices and security standards (e.g., CIS benchmarks, NIST guidelines) for server hardening and configuration management.
• Conduct regular security audits and vulnerability assessments to identify and remediate security weaknesses and compliance violations.
• Maintain documentation of security configurations, audit findings, and remediation actions for compliance purposes and security governance.
10. Continual Improvement:
• Stay informed about emerging security threats, vulnerabilities, and best practices through security advisories, mailing lists, and industry forums.
• Continuously review and update security policies, procedures, and controls to address evolving security risks and regulatory requirements.
• Conduct periodic security assessments and penetration testing to evaluate the effectiveness of security controls and identify areas for improvement
Docker Basics:
1. What is Docker?:
• Docker is an open-source platform that enables developers to build, package, distribute, and run applications in lightweight, portable containers.
• Containers encapsulate the application and its dependencies into a single unit, providing consistency and isolation across different environments.
2. Key Concepts:
• Docker Image: A read-only template containing the application code, runtime, libraries, and other dependencies needed to run the application.
• Docker Container: An instance of a Docker image that runs as a lightweight, isolated process on the host machine.
• Dockerfile: A text file that contains instructions for building a Docker image, specifying the base image, dependencies, and configuration.
• Docker Engine: The runtime environment that manages Docker containers and provides tools for building, running, and managing containerized applications.
3. Basic Commands:
• docker run: Creates and starts a new container based on a specified Docker image.
• docker build: Builds a Docker image from a Dockerfile.
• docker pull: Downloads a Docker image from a registry (e.g., Docker Hub).
• docker push: Pushes a Docker image to a registry.
4. Container Lifecycle:
• Create: Create a new container from an image.
• Start: Start a stopped or paused container.
• Stop: Stop a running container.
• Restart: Restart a container.
• Remove: Remove a container.
Kubernetes Basics:
1. What is Kubernetes?:
• Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.
• Kubernetes provides a framework for deploying, scaling, and managing applications across clusters of hosts.
2. Key Concepts:
• Pod: The smallest deployable unit in Kubernetes, representing one or more containers that share resources and network namespaces.
• Deployment: A Kubernetes resource that manages a set of identical pods, ensuring high availability and scalability.
• Service: A Kubernetes resource that provides network access to a set of pods, enabling load balancing and service discovery.
• Namespace: A logical partition within a Kubernetes cluster that provides a scope for names and resource isolation.
• Cluster: A collection of nodes (physical or virtual machines) that run containerized applications managed by Kubernetes.
3. Basic Commands:
• kubectl create: Create a new Kubernetes resource (e.g., pod, deployment, service).
• kubectl apply: Apply configuration changes to a Kubernetes resource.
• kubectl get: Retrieve information about Kubernetes resources.
• kubectl describe: Display detailed information about a Kubernetes resource.
• kubectl delete: Delete a Kubernetes resource.
4. Deployment Workflow:
• Define the desired state of the application using Kubernetes manifests (YAML or JSON files).
• Apply the manifests using kubectl apply to create or update the application deployment.
• Monitor the deployment using kubectl get and kubectl describe commands.
• Scale the deployment up or down using kubectl scale.
• Perform rolling updates or rollback using kubectl rollout.
5. Service Discovery and Load Balancing:
• Kubernetes services provide a stable endpoint for accessing a set of pods, enabling service discovery and load balancing across the cluster.
• Services can be exposed internally within the cluster or externally to the internet using different service types (ClusterIP, NodePort, LoadBalancer, Ingress).
6. Scaling and Self-Healing:
• Kubernetes supports horizontal scaling of applications by adding or removing pod replicas based on resource utilization and user-defined metrics.
• Kubernetes provides self-healing capabilities, automatically restarting containers and rescheduling pods in case of failures or crashes.
