aaronp / argo-drone

A K8S repo for argoCD and drone

argo-demo

This repo is a playground/demo for use of Argo CD (docs).

It contains examples for runnin up a kubernetes cluster either locally or on a cloud provider (see "Set up a Kubernetes cluster" below), an example "helloworld" app, and other sundry examples.

Pre-requisites

• A GitHub account (other repositories are available)
• Homebrew is installed (assumes mac)

Note: This guide assumes the use of MacOS with permissions to be able to install various apps

1) Set up a Kubernetes Cluster

See:

• aws
• azure
• gcp
• kube <- for local k8s using kind

From here, we assume kubectl is installed/authenticated.

2) Deploy Argo to Kubernetes

8) With argo in place, we can install drone

See here to set up the OAuth app in github.

Then run installDrone.sh with the github oauth client ID and secret.

9) Connect our example app

Let's recall the name from our container registry from earlier.

e.g., on Azure, our args.sh variables would be defined as:

export MY_CLUSTER_NAME=... 
export MY_GROUP_NAME=...
export MY_REGISTRY_NAME=...
az aks check-acr -n "$MY_CLUSTER_NAME" -g "$MY_GROUP_NAME" --acr "$MY_REGISTRY_NAME"

To get the ACR we would run:

MY_ACR_SCOPE=$(az acr show --name s"${MY_REGISTRY_NAME:?}" --query "id" --output tsv)

Create a service principle for the container registry

[[ -z "${MY_APP_PRINCIPAL}" ]] && export MY_APP_PRINCIPAL="${MY_APP_NAME}Principle"

export MY_ACRPUSH_PWD=$(az ad sp create-for-rbac --name "${MY_APP_PRINCIPAL:?}" --scopes "${MY_ACR_SCOPE:?}" --role acrpush --query "password" --output tsv)
export MY_ACRPUSH_USR=$(az ad sp list --display-name "${MY_APP_PRINCIPAL:?}" --query "[].appId" --output tsv)
