What is Docker?This time again a tutorial with various instructions. NET Core API, deploy to DockerHub, and run on Windows, Linux and Azure. 4 For example, to set the Docker images demisto/dl (all tags) to use a.In this how-to, we create a Docker image based on a. Docker run -it -p 9390:9390 siddhiio/siddhi-tooling:5.1.0.In the API Key field, type the value of the ExtraHop REST API key you generated. Make sure, you already have a docker installation (Docker for Mac or Docker for Windows or Docker CE or any other docker engines) locally. REST API Guides REST API Guides Siddhi App APIs On-Demand Query APIs Health Check APIs Store APIs (Deprecated) Default Ports HTTP Status Codes.

Containers provide App Level VirtualisationIn short you would use Docker, (and hence containers), for the following reasons: Virtual Machines provide OS Level Virtualisation The rest of the tutorial shows how you can grant fine grained access to specific.They are similar, but not the same. Are Containers the same as Virtual Machines?Docker Engine 18.06.0-ce or newer Docker API version 1.38 or newer. It negates the classic: вЂњIt works on my computerвЂќ argument as Docker images contain everything needed for the app to run. VirtualBox installed docker-machine installed Note: For Mac OS X and Windows use Docker Toolbox Create and connect into Boot2Docker VMDocker is a containerization platform, meaning that it enables you to package your applications into images and run them as вЂњcontainersвЂќ on any platform that can run Docker.

Create Our AppWeвЂ™re only going to create an out the box. Docker Hub (you need this if you want to pull to a local environment too)With our prerequisites installed, and any optional cloud hosting accounts set up, letвЂ™s move on to creating our app. VS Code text editor, (you can use anything you like but IвЂ™d recommend this)IвЂ™ve provided links to all of the above, where you should be able to find not just the software, but install instructions for your respective operating system.NOTE: Windows users at install time be sure to leave the default as вЂњLinux ContainersвЂќ, (as opposed to selecting Windows containers).Additionally, if you want to follow along with the cloud deployments, youвЂ™ll need accounts on: The level of Docker adoption in industry means that itвЂ™s a great skill to have.In order to follow along with this tutorial youвЂ™ll need: Containers generally perform better than their VM counterparts. With the use of additional вЂњorchestrationвЂќ you can spin up multiple container instances to support increased load.

Images & ContainersBefore we set up our app to run in Docker, you should be familiar with 2 terms that youвЂ™ll hear frequently when talking about Docker: Images and Containers. NET Core API together, check out this article. Once youвЂ™re comfortable with the concepts by all means use the вЂњwizardвЂќ functionality in Visual Studio to streamline your use of Docker.So to create our API app, open a command prompt and type: dotnet new webapi -n SimpleAPIThis will create an API project called вЂњSimpleAPIвЂќ, you should see output similar to the following:Start VSCode and select: File -> Open Folder and select the вЂњSimpleAPIвЂќ project folder that was just created in the last step:Open the Startup.cs class, and remove the following code from the Configure method, (this just makes the testing of the app a little bit simpler вЂ“ in a production app you may want to consider keeping this code though):So all you should have in the configure method now is: app.UseMvc() Save the file, and at a command prompt, change вЂњintoвЂќ, the SimpleAPI project directory, (listing the contents of the folder you should see):This will start the app on localhost on ports 5000 & 5001 for http and https requests respectively:Now open a browser, and enter the following URL: This вЂњhitsвЂќ the following API Controller action:ThatвЂ™s all weвЂ™ll be doing with our API app, so if that didnвЂ™t make much sense and you want a more detailed explanation on how to put a. NET Core CLI), as I feel that lays better foundations for learning. NET Core API build guide however, I have covered that in this article.IвЂ™m going to take a highly manual approach to everything in this article, (e.g.

You can take 1 image and spin up multiple containers instancesвЂ¦So the first thing we need to do to get our app running in Docker is to create an image, we do that by introducing a вЂњDockerfileвЂќ to our project. Analogy with OO DevelopmentWhen I starting out with Docker I made the following analogy with Object-oriented software development, (as I was more familiar with that):While this comparison may not be 100% accurate, I feel its close enough to be useful. ContainerWhen our image is вЂњexecuted to runвЂќ, in runs in a container, which as weвЂ™ve already discussed is highly portable and independent, (from any other running containers).

Line 2: So that the Docker Engine can compile our app, we grab the. The first step is to add a file named вЂњDockerfileвЂќ in the root of our project, (note that the file has no extension):If youвЂ™re using VS Code it may ask you to install an extension that will give you Dockerfile syntax parsing, (or IntelliSense), as well as some other useful features вЂ“ I recommend you install it:Now in your Docker file add the following sections, weвЂ™ll go through whatвЂ™s happening at each step below:FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build-envFROM mcr.microsoft.com/dotnet/core/aspnet:2.2Referring to the line numbers below, IвЂ™ll explain whatвЂ™s happening at each step next: The Docker engine will create an image ready for useSo lets get started and create our Dockerfile. Using the Docker CLI will issue a вЂњbuildвЂќ command

Csproj file and retrieving any additional dependencies via Nuget) Line 7: Using dotnet restore we resolve any project dependencies (this is done using the. Csproj file from our PC to the working container directory (/app)

Line 17: Copy the relevant files from both the dependency resolution step, ( build-env), and build step, ( /app/out), to our working directory /app Line 16: We expose the port we want to use from inside our app Line 15: Re-specify our working directory Line 14: To keep our image вЂњleanвЂќ we retrieve only the aspnet run time image, (as opposed t the full SDK image we used for building), as this is all our app requires to вЂњrunвЂќ. Line 11: We run the dotnet publish command, specifying that it is a Release build, ( -c Release), as well as specifying a folder, ( out), to contain the app build dll and any support files & libraries.

DockerignoreВ again note there no extension. Additionally, to minimise the footplaint of our image, you should include a 2nd file in the root of our project called. NET SDK base image to allow for the compilation of our app.Save Docker file. Therefore we have to assume that the container environment is вЂњemptyвЂќ, hence why we need to pull down the. Dll using вЂњdotnetвЂќ.* The Docker Engine builds up an image in stages by using an empty container at each stage and working inside that. What should start), in this case itвЂ™s our published.
