  • 4.From Containers to Microservices • Containers have dependencies with eachother • Docker Compose • Tool for defining and running multi-container Docker applications • Services and their configurations are defined in YAML file(s)

  • 7.Docker Containers – Best practices • Run one process per container • Config through env • Don’t rely on anything • Databases at startup • Downstream services • Logs in stdout/stderr • Don’t rely on IP addresses © 2015 Kontena, Inc.

  • 9.Rolling to Production • How big this app will be? How many users it will serve? • Do you want your application to be infrastructure agnostic or lean heavily on some cloud provider? • How to run databases or save other persistent data? • How to scale the application and handle load balancing? • How do you pass sensitive data to your application and where to store that data? • How the application can be deployed and updated with zero downtime? © 2015 Kontena, Inc.

  • 11.Kontena briefly
  • 12.What is Kontena? Open Source container platform built to maximize developer happiness. Works on any cloud, easy to setup, simple to use. © 2015 Kontena, Inc.
  • 13.How does it work? Kontena Nodes & Agent Kontena Agent may be installed to any machine capable of running Docker. It is running as a privileged container in a machine. Containerized Workloads With Kontena, all containerized workloads are described as Services. Kontena Service is composed of containers based on the same image file. Services may be scaled and linked together to create complex elastic apps. Docker OS Orchestration Kontena’s orchestrator is distributing, running and monitoring all Kontena Services in a Grid. Services may be stateless or stateful, and they are automatically distributed across Nodes in a Grid. Service Discovery Kontena has a built-in service discovery powered by etcd. It is used to automatically assign DNS addresses for any services running in Kontena. It is also used by Kontena’s load balancer for zero-downtime operation. Kontena Master Kontena Master is orchestrating the entire Kontena system. It provides APIs used by Kontena CLI, Web UI and third party integrations. Kontena Master may be installed as high-availability setup if needed. Overlay Network Kontena will automatically create an overlay network powered by Weave and connect all nodes of a Grid. Overlay network enable services to communicate with each other in multi-host, multi-AZ environment. Kontena Grid A number of physical or virtual machines – Kontena Nodes – create a Kontena Grid. The nodes may be located anywhere; in single data center, different AZs or different cloud providers.
  • 14.All Batteries Included! Built-In Image Registry Sometimes projects can not use publicly hosted container image registries like DockerHub. Kontena comes with built-in container image registry providing private and secure solution. Aggregated Stats & Logs Kontena provides real-time log and statistics streams containers. The streams may be grouped and aggregated to produce service level streams. This allows easy viewing of logs and statistics for your application CPU, memory, disk and network usage. Built-In VPN Access All containers are run inside a virtual private network by default. Nothing is exposed to Internet unless explicitly defined. With Kontena’s built-in VPN access developers can securely access those resources. User Management with Audit Trail All events and actions performed through Kontena CLI or APIs are logged into audit trail. Combined with users and access control, the audit trail support makes Kontena a reliable and secure solution for any enterprise deployments. Built-In Load Balancer Kontena comes with built-in load balancer. Based on Haproxy. It features fully automatic, zero-downtime operation due to deep integration with Kontena’s service discovery and orchestration technology. Built-In Secrets Management When your application requires access to APIs or databases, you'll often need to use secrets such as passwords and access tokens for authenticating the access. Kontena Vault is a secure key/value storage that can be used to manage secrets in Kontena.
