15 - Deploy

Deploy

Deploy your ASP.NET Core MVC App into cloud – MS Azure

Several ways how to do it

  • Full bare metal server
  • Virtual server
  • App hosting (azure) (deployable directly from Rider)
  • Most standardized way – containers – Docker

Docker

Docker

Docker desktop

Download and install docker desktop for your platform (apple m1 is fully supported)

Its free!

https://hub.docker.com

When you create a docker image of your app, you need to upload it to somewhere – so hosting can download it from there. Typically, docker hosts do not allow direct uploads! Docker hub is free service to host your public images.

Dockerfile

  • Create Dockerfile in solution folder
  • It uses two ready-made base images from MS (based on Debian 10)
  • sdk:6.0 – for building (or :latest)
    Full .net core sdk
  • aspnet:6.0 – for running (or :latest)
    This image only contains .net core and ASP.NET runtime – its smaller

.dockerignore

To keep size even more down and control the bin/obj directory problems - add .dockerignore

Build image

  • Build your app into docker image
    > docker build -t webapp .

  • Run it locally via docker (set envs for db if needed)
    > docker run --name webapp_docker --rm -it -p 8000:80 webapp

    • -p 8000:80 – map port 8000 (local machine) to docker port 80
    • --name webapp_docker – name of instance
    • -it – interactive (can close down with ctrl-c)
    • --rm - clean resources after closing down


Open browser to http://localhost:8000/

Publish image

  • Tag your docker image (needed for publishing) > docker tag webapp akaver/webapp:test

  • Publish your docker image to registry
    > docker login -u [username] -p [password]
    > docker push akaver/webapp:test  

  • Check your image in Docker Hub

Docker

Deploy - Azure

  • Create Azure account, (using your TalTech Uni-Id)
    • Sadly, no student support currently – or maybe it works for you! (has worked randomly)
  • Activate free plan (or pay-as-you-go)

Docker

Azure Basics

  • Create new resource group - easy to kill everything later in one go
  • Instance name – some_website_name.azurewebsites.net
  • Publish: Docker image
  • Operating system: Linux
  • Location: North Europe
  • Sku and size: Free F1

Docker

Azure Docker

  • Options: Single Container
  • Image Source: Docker Hub
  • Access Type: Public
  • Image and tag: [your_repo/your_image:your_tag]

Docker

  • Create!

Docker

  • Ca 2 min later

Docker

Container update

  • Get the webhook url for docker registry – this notifies the Azure when new image is available.
  • Deployment Center > Webhook URL
