ylochman / cloud-infrastructure

Cloud Infrastructure coursework | Applied Sciences Faculty, UCU (2019)

• Service + Dockerfile
• YAML scripts for installing into Kubernetes
• Bash script, that installs the service into MiniKube automatically
• Kubernetes Readiness check + Liveness check
• Bash script for local deployment in Minikube (without cloud library of containers)
• Memory scaling

1. An application + Dockerfile

You can simply run an application in a single container:

from Docker Hub:

• run docker run -d -p 5000:5000 --rm --name ylochman-cloud-infra ylochman/apps-cloud-infra:latest

or locally:

• clone this repository: git clone https://github.com/ylochman/apps-cloud-infra.git
• run docker build -t ylochman-hw .
• run docker run -d -p 5000:5000 --rm --name ylochman-cloud-infra ylochman-hw

Then go to localhost:5000 and follow the instructions. To stop and remove container run:

docker container stop $(docker container ls -f "name=ylochman-cloud-infra" -q) .

2 - 6. Deployment of an application with Minikube

Clone this repository and go to deploy-kubernetes

YAML maps are located there:

• deployment-cloud.yaml (with Readiness & Liveness check)
• deployment-local.yaml (with Readiness & Liveness check)
• deployment-service.yaml
• deployment-autoscaling.yaml

Run chmod +x ./create-deploy-cloud.sh ./create-deploy-local.sh ./delete-deploy.sh

To deploy an application:

• from cloud registry run ./create-deploy.sh -m
• from local image simply add options -l and -b: ./create-deploy.sh -mlb.

Here the opions are:

-m - first start minikube

-l - deploy an application from local image

-b - build docker image locally before runing

To delete a deployment run ./delete-deploy.sh -m. Here -m is to stop minikube.

Deployment of an application with Docker Machine

It was done for practicing

Go to deploy-docker-machine

Run chmod +x ./create-deploy.sh ./stop-deploy.sh

To deploy an application onto a swarm cluster run ./create-deploy.sh

To stop application run ./stop-deploy.sh
