Creation of the Azure VM

First we need a machine, you may install docker on our physical machine, but you can also provision an Azure VM, which is what we are doing here.

Creation

Create VM of type: 'Standard E4 v3' (4 vcpus, 32 GB memory), VM of type 'E* v3' comes with HyperV supported.

Reference Documents

VM Configuration

Once the VM is running connect via RDP and execute the following PowerShell commands.

# Step 1 - Ensure Windows Hyper-V featutes are enabled by running PowerShell cmdlet:
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All -Verbose
# You should be asked to reboot.

# Step 2 - Ensure Windows Containers feature is enabled by running PowerShell cmdlet:
Enable-WindowsOptionalFeature -Online -FeatureName Containers -All -Verbose

# Step 3 - Ensure Hypervisor is set to auto start in the Boot Configuration Database (BCD) by running in elevated command prompt the command:
bcdedit /set hypervisorlaunchtype Auto

# Reboot

Docker

Installation

Download and install Docker

Install Docker Desktop for Windows You will be asked to log out and log in.

Testing the Docker Installation

Hyper V Manager

Start Hyper-V Manager. You should see the MobyLinuxVM running inside.
We can increase the memory allocated to the MobyLinuxVM using the Hyper-V Manager UI.

Docker account

You may need an account for the web site hub.docker.com. - Create an account http://hub.docker.com Login: docker login # username:usual, password:cat

Testing local installation of Docker

C:\>docker version # Show the docker client side and server side

We expect the client side to be Windows and the server side to be Linux.

Output

Client: Docker Engine - Community
OS/Arch:           windows/amd64
Experimental:      false
Server: Docker Engine - Community
OS/Arch:          linux/amd64

C:\>docker ps # At this point no container instance should be running 
C:\>docker images ps # At this point to the contains repository should be empty

Let's download and execute an Hello World image
For more information about the Hello World Image

# Download from hub.docker.com as a default
C:\>docker pull library/hello-world 
C:\>docker run library/hello-world # execute 
C:\>docker ps --all # Show history of container execution

Let's download a small version of Ubuntu
Run the OS and execute a bash command

# Download ubuntu and execute a bash command
C:\>docker run ubuntu /bin/bash -c "echo Hello World"

Run the container in background mode, detached from the console

C:\>docker run --detach --name helloworld  ubuntu /bin/bash -c "while true; do echo Hello World; sleep 1; done"
C:\>docker logs helloworld # see the output of the container
C:\>docker exec helloworld "uname" # run command uname inside the running container which output the name of the OS
docker stop helloworld # stop running container

Download the dotnet runtime and query for information

C:\>docker run --rm -it microsoft/C:\>dotnet:2-runtime dotnet --info

How to visualize information about a container image using the inspect tool?

# How to get informaton about a docker image
C:\>docker inspect microsoft/dotnet:2-runtime

How to build and run ASP.NET Core Web App, Rest API with Docker support (Not finished).

Create an ASP.NET Core Web App, Rest API with Docker support.
- Run inside IIS Express: https://localhost:44389/api/values
- Run inside a container
When running app for the first time IIS Express mode or Docker mode may fail, but run the second times.

dotnet run # will compile and run the app from the command line

docker stop fwebapidockerized:dev # How to stop a running container 
docker stop cde304650124 # How to stop a running container

docker rmi fwebapidockerized:dev --force # how to delete an image
docker rmi cde304650133 --force # how to delete an image

# Variant 1 - how to build a container from the command line
dotnet publish -c Release
docker build -t fwebapidockerized --build-arg source=bin\Release\netcoreapp2.1\publish .

# Variant 2 - how to build a container from the command line
# How to build a docker image from a current aspnetcore project
docker build -f "C:\DVT\FWebApiDockerized\Dockerfile" -t fwebapidockerized:dev --target base --label "com.microsoft.created-by=visual-studio" "C:\DVT"

How to clean the image repository

# Get a list of id from an image name with wild card - return an array
$ids = docker images  "fredcontainerregistry.azurecr.io/donation.personsimulator.con*" -q
# Delete all images from id
$ids | ForEach-Object -Process { docker rmi $_ }
