Petabridge.Phobos.Web.InfluxDB

This repository is derived from the code we use in the Phobos Quickstart Tutorial, which you can read here Everything is more or less the same, except our choice of App.Metrics back-end.

NOTE: this solution uses the shared Phobos + InfluxDB Grafana dashboard built by Petabridge, which you can install in your own application via Grafana Cloud here: https://grafana.com/grafana/dashboards/13964

This project is a ready-made solution for testing Phobos in a real production environment using the following technologies:

Build and Local Deployment

Start by cloning this repository to your local system.

Next - to build this solution you will need to purchase a Phobos license key. They cost $4,000 per year per organization with no node count or seat limitations and comes with a 30 day money-back guarantee.

Once you purchase a Phobos NuGet keys for your organization, you're going to want to open NuGet.config and add your key:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <solution>
    <add key="disableSourceControlIntegration" value="true" />
  </solution>
  <packageSources>
    <clear />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
    <add key="phobos" value="{your key here}" />
  </packageSources>
</configuration>

From there, run the following commad on the prompt:

PS> build.cmd Docker

This will create the Docker images the solution needs to run inside Kubernetes: petabridge.phobos.web.influxdb:0.1.3.

Deploying the K8s Cluster (with Telemetry Installed)

From there, everything you need to run the solution in Kubernetes is already defined inside the k8s/ folder - just run the following command to launch the Phobos-enabled application inside Kubernetes:

PS> ./k8s/deployAll.cmd

This will spin up a separate Kubernetes namespace, phobos-web, and you can view which services are deployed by running the following command:

PS> kubectl get all -n phobos-web

You should see the following or similar output:

NOTE: the restarts from the phobos-web-* pods come from calling Dns.GetHostName() prior to the local K8s service allocating its hostnames. Nothing to worry about - it'll resolve itself in a few moments.

Once the cluster is fully up and running you can explore the application and its associated telemetry via the following Urls:

There's many more metrics exported by Phobos that you can use to create your own dashboards or extend the existing ones - you can view all of them by going to http://localhost:1880/metrics

Tearing Down the Cluster

When you're done exploring this sample, you can tear down the cluster by running the following command:

PS> ./k8s/destroyAll.cmd

This will delete the phobos-web namespace and all of the resources inside it.

Other Build Script Options

This project supports a wide variety of commands, all of which can be listed via:

Windows

c:\> build.cmd help

Linux / OS X

c:\> build.sh help

However, please see this readme for full details.

Summary

  • build.[cmd|sh] all - runs the entire build system minus documentation: NBench, Tests, and Nuget.
  • build.[cmd|sh] buildrelease - compiles the solution in Release mode.
  • build.[cmd|sh] tests - compiles the solution in Release mode and runs the unit test suite (all projects that end with the .Tests.csproj suffix). All of the output will be published to the ./TestResults folder.
  • build.[cmd|sh] nbench - compiles the solution in Release mode and runs the NBench performance test suite (all projects that end with the .Tests.Performance.csproj suffix). All of the output will be published to the ./PerfResults folder.
  • build.[cmd|sh] nuget - compiles the solution in Release mode and creates Nuget packages from any project that does not have <IsPackable>false</IsPackable> set and uses the version number from RELEASE_NOTES.md.
  • build.[cmd|sh] nuget nugetprerelease=dev - compiles the solution in Release mode and creates Nuget packages from any project that does not have <IsPackable>false</IsPackable> set - but in this instance all projects will have a VersionSuffix of -beta{DateTime.UtcNow.Ticks}. It's typically used for publishing nightly releases.
  • build.[cmd|sh] nuget SignClientUser=$(signingUsername) SignClientSecret=$(signingPassword) - compiles the solution in Release modem creates Nuget packages from any project that does not have <IsPackable>false</IsPackable> set using the version number from RELEASE_NOTES.md, and then signs those packages using the SignClient data below.
  • build.[cmd|sh] nuget SignClientUser=$(signingUsername) SignClientSecret=$(signingPassword) nugetpublishurl=$(nugetUrl) nugetkey=$(nugetKey) - compiles the solution in Release modem creates Nuget packages from any project that does not have <IsPackable>false</IsPackable> set using the version number from RELEASE_NOTES.md, signs those packages using the SignClient data below, and then publishes those packages to the $(nugetUrl) using NuGet key $(nugetKey).
  • build.[cmd|sh] DocFx - compiles the solution in Release mode and then uses DocFx to generate website documentation inside the ./docs/_site folder. Use the ./serve-docs.cmd on Windows to preview the documentation.

This build script is powered by FAKE; please see their API documentation should you need to make any changes to the build.fsx file.

Deployment

Petabridge.App uses Docker for deployment - to create Docker images for this project, please run the following command:

build.cmd Docker

By default build.fsx will look for every .csproj file that has a Dockerfile in the same directory - from there the name of the .csproj will be converted into the supported Docker image name format, so "Petabridge.App.csproj" will be converted to an image called petabridge.app:latest and petabridge.app:{VERSION}, where version is determined using the rules defined in the section below.

Pushing to a Remote Docker Registry

You can also specify a remote Docker registry URL and that will cause a copy of this Docker image to be published there as well:

Release Notes, Version Numbers, Etc

This project will automatically populate its release notes in all of its modules via the entries written inside RELEASE_NOTES.md and will automatically update the versions of all assemblies and NuGet packages via the metadata included inside common.props.

RELEASE_NOTES.md

#### 0.1.0 October 05 2019 ####
First release

In this instance, the NuGet and assembly version will be 0.1.0 based on what's available at the top of the RELEASE_NOTES.md file.

RELEASE_NOTES.md

#### 0.1.0-beta1 October 05 2019 ####
First release

But in this case the NuGet and assembly version will be 0.1.0-beta1.

If you add any new projects to the solution created with this template, be sure to add the following line to each one of them in order to ensure that you can take advantage of common.props for standardization purposes:

<Import Project="..\common.props" />

Conventions

The attached build script will automatically do the following based on the conventions of the project names added to this project:

  • Any project name ending with .Tests will automatically be treated as a XUnit2 project and will be included during the test stages of this build script;
  • Any project name ending with .Tests.Performance will automatically be treated as a NBench project and will be included during the test stages of this build script; and
  • Any project meeting neither of these conventions will be treated as a NuGet packaging target and its .nupkg file will automatically be placed in the bin\nuget folder upon running the build.[cmd|sh] all command.

DocFx for Documentation

This solution also supports DocFx for generating both API documentation and articles to describe the behavior, output, and usages of your project.

All of the relevant articles you wish to write should be added to the /docs/articles/ folder and any API documentation you might need will also appear there.

All of the documentation will be statically generated and the output will be placed in the /docs/_site/ folder.

Previewing Documentation

To preview the documentation for this project, execute the following command at the root of this folder:

C:\> serve-docs.cmd

This will use the built-in docfx.console binary that is installed as part of the NuGet restore process from executing any of the usual build.cmd or build.sh steps to preview the fully-rendered documentation. For best results, do this immediately after calling build.cmd buildRelease.

Code Signing via SignService

This project uses SignService to code-sign NuGet packages prior to publication. The build.cmd and build.sh scripts will automatically download the SignClient needed to execute code signing locally on the build agent, but it's still your responsibility to set up the SignService server per the instructions at the linked repository.

Once you've gone through the ropes of setting up a code-signing server, you'll need to set a few configuration options in your project in order to use the SignClient:

  • Add your Active Directory settings to appsettings.json and
  • Pass in your signature information to the signingName, signingDescription, and signingUrl values inside build.fsx.

Whenever you're ready to run code-signing on the NuGet packages published by build.fsx, execute the following command:

C:\> build.cmd nuget SignClientSecret={your secret} SignClientUser={your username}

This will invoke the SignClient and actually execute code signing against your .nupkg files prior to NuGet publication.

If one of these two values isn't provided, the code signing stage will skip itself and simply produce unsigned NuGet code packages.
