Kubernetes is hard. Getting started and set up for the first time can take weeks to get right. Managing deployments on a fleet of Kubernetes clusters on the edge brings even more challenges.
Pilot-in-a-Box (PiB) is a game-changer
for the end-to-end Kubernetes app development cycle from a local cluster to deployments on the edge. It reduces the initial friction and empowers the developer to get started and deployed to a dev/test environment within minutes. The pre-configured Codespaces environment includes a Kubernetes
cluster and custom CLI's (kic
and flt
) that help streamline the initial learning curve to Kubernetes development commands.
This repo walks through the rich end-to-end developer experience in a series of labs. The labs start by walking you through creating, building, testing, and deploying an application on a local cluster (inner-loop) with a complete CNCF observability stack. Then, the labs move on to the next step of deploying the application to a test cluster in the Cloud (outer-loop). There are also several advanced labs that cover centralized monitoring, canary deployments, and targeting different devices.
PiB is not intended for production deployments. However, some concepts covered (GitOps and Observability) are production-ready
- GitHub Codespaces access
- An Azure subscription with owner access
- A free Azure subscription will work for exploration
- Some advanced scenarios also require AAD permissions
- The base Codespaces images recently updated to dotnet core 7
- PiB currently uses dotnet core 6
- Both dotnet core 6 and 7 are installed in the Codespaces image as we migrate to dotnet 7
Codespaces allows you to develop in a secure, configurable, and dedicated development environment in the cloud that works how and where you want it to
- GitHub Codespaces Overview
- GitHub Codespaces is available for organizations using GitHub Team or GitHub Enterprise Cloud. GitHub Codespaces is also available as a limited beta release for individual users on GitHub Pro plans.
- For more information, see "GitHub's products"
We use GitHub Codespaces for our inner-loop
and outer-loop
Developer Experiences. While other DevX are available, currently, we only support GitHub Codespaces.
The easiest way to get GitHub Codespaces access is to setup a GitHub Team
GitHub Codespaces is also available in beta on a limited basis for GitHub Pro users. The waiting list is normally > 3 months.
Best Practice: as you begin projects, ensure that you have Codespaces and Azure subscriptions with proper permissions
inner-loop
refers to the tasks that developers do every day as part of their development process- Generally,
inner-loop
happens on the individual developer workstation- For PiB, the inner-loop and developer workstation is Codespaces
- When a developer creates a Codespace, that is their "personal development workstation in the cloud"
- Generally,
- As part of PiB, we have automated the creation of the developer workstation using a repeatable, consistent, Infrastructure as Code approach
- We have an advanced workshop planned for customizing the Codespaces experience for your project
- With the power of Codespaces, a developer can create a consistent workstation with a few clicks in less than a minute
outer-loop
refers to the tasks that developers and DevOps do as they move from dev to test to pre-prod to production- Generally
outer-loop
happens on shared compute outside of the developer workstation - For PiB, outer-loop uses a combination of Codespaces and
dev/test clusters
in Azure

You can use the same Codespace for any of the labs
- From this repo
- Click the
<> Code
button- Make sure the Codespaces tab is active
- Click
Create Codespace on main
- Click the
- After about 1 minute, you will have a GitHub Codespace running with a complete Kubernetes Developer Experience!
Many of these tutorials make use of environment variables, using the export functionality. If you wish, you can also edit the Z shell preferences file to persist exported environment variables across terminal sessions. Just add the same "export FOO=BAR" lines to your .zshrc file.
code ~/.zshrc

Because the main branch has a branch protection rule, you need to create a working branch
- You can use the same branch for any of the labs or create a new branch per lab (add 1, 2, 3 ... to the branch name)
๐ Many commands will fail in following labs if
MY_BRANCH
is not set or branch is not pushed upstream# by default, MY_BRANCH is set to your lower case GitHub User Name # the value can be overwritten if needed echo $MY_BRANCH # create a branch git checkout -b $MY_BRANCH # push the branch and set the remote git push -u origin $MY_BRANCH
-
Your prompt should end like this
- /workspaces/Pilot-in-a-Box (mybranch) $
- Lab 1: Create, build, deploy, and test a new dotnet application and observability stack on your local cluster
- Lab 2: Configure flux to automate the deployment process from Lab 1
-
Lab 1: Create a dev/test cluster and manage application deployments on the cluster
-
Lab 2: Manage application deployments on a fleet of multiple clusters
-
Lab 3: Configure ring based deployments
-
Lab 4: Set up Azure subscription and Codespaces for advanced configuration
- This is a prerequisite for the Advanced Labs
- Arc enabled GitOps Lab: Deploy to dev cluster running on an Azure VM with Arc enabled GitOps
- Canary Deployment Lab: Use Flagger to experiment with canary deployments
- Vision on Edge (VoE) Lab: Deploy a more complex app (VoE) to a fleet
- Centralized Observability Lab: Deploy a centralized observability system with Fluent Bit, Prometheus, and Grafana to monitor fleet application deployments
- outer-loop with AKS-IoT: Deploy to an AKS-IoT cluster running on an Azure VM with Arc enabled GitOps
- outer-loop with AKS Lab: Deploy to an AKS cluster with Arc enabled GitOps

Once you are finished experimenting, please delete your branch
# change to the root of the repo cd $PIB_BASE git pull git add . git commit -am "deleting branch" git push # checkout main branch, delete remote, delete local git checkout main git push origin $MY_BRANCH --delete git branch -D $MY_BRANCH
