architechture, docker, and kubernetes

Patterns with docker

06 Aug 2018

I’ve been actively using Docker and Kubernetes (k8s) at work for a while now. Here are few patterns I gathered.

Patterns

Docker

• Master docker command line. The basic knowledge will help.
• docker-compose is quite handy to get started with brand-new projects.
• Use a repository. You can use Gitlab Docker Registry, portus, etc.
• Use pipeline to build containers.
• Use Clair to find vulnabarilty in images.
• Smaller docker images are good.

Kubernetes

• Use minikube locally to have a flavor of kubernetes.
• helm chart is quite useful to roll-forward/roll-back containers.
• Consider Docker as a Service solutions to roll out faster - AWS ECS, Google Kubernetes Engine, Azure Container Service, Digital Ocean etc.
• Alternatively, use Ansible (or your favorite tool) to configure a k8s cluster from scratch.
