Best Practices and Tips for Writing a Dockerfile

Docker is a high-level virtualization platform that lets you package software as isolated units called containers. Containers are created from images that include everything needed to run the packaged workload, such as executable binaries and dependency libraries. Images are defined in Dockerfiles. These resemble sequential scripts that are executed to assemble an image.

The Best Tools for Monitoring Your Docker Container

It can be difficult to comprehend and successfully scale your services as modern orchestrated settings grow larger and more sophisticated. Container monitoring allows you to see the health and performance of your dynamic container infrastructure in real-time. Container monitoring is the practice of collecting and analyzing performance metrics to track the performance of containerized applications built on cloud-based microservices.

Workload access control: Securely connecting containers and Kubernetes with the outside world

Containers have changed how applications are developed and deployed, with Kubernetes ascending as the de facto means of orchestrating containers, speeding development, and increasing scalability. Modern application workloads with microservices and containers eventually need to communicate with other applications or services that reside on public or private clouds outside the Kubernetes cluster. However, securely controlling granular access between these environments continues to be a challenge.

The What and The Why of Cloud Native Applications - An Introductory Guide

Companies across industries are under tremendous pressure to develop and deploy IT applications and services faster and with far greater efficiency. Traditional enterprise application development falls short since it is not efficient and speedy. IT and business leaders are keen to take advantage of cloud computing as it offers businesses cost savings, scalability at the touch of a button, and flexibility to respond quickly to change.

Bulletproofing Your Kubernetes Build

Most containers, pods, and namespaces in Kubernetes and OpenShift have been deployed with incorrect CPU and memory resource specifications. It isn’t just suboptimal DevOps—it’s dangerous from a service delivery perspective. Watch and see how managing capacity operationally prevents pods from swallowing unused capacity, frees nodes, and keeps the OOM killer away. This bulletproof strategy for maximizing utilization continuously integrates the optimal resources into the source code controlling your nodes and clusters.

Enterprise Kubernetes use cases: 4 real-world stories

There are common patterns and best practices across different verticals to be successful with Kubernetes adoption and everything starts with setting the appropriate business goals. Canonical is helping businesses in various industries, such as Telco, FinServ, Human Resources and the public sector to define the right cloud native strategy and implement a fully open source solution tailored to their needs.
