PiB outer-loop with Arc Enabled Gitops

Login to Azure

  • Login to Azure using az login --use-device-code

    Use az login --use-device-code --tenant <tenant> to specify a different tenant

    • If you have more than one Azure subscription, select the correct subscription

      # verify your account
az account show

# list your Azure accounts
az account list -o table

# set your Azure subscription
az account set -s mySubNameOrId

# verify your account
az account show

Create/Set Managed Identity

  • If you don't already have managed identity set in your subscription, follow these steps to create RG and MI
  • Run flt env and make sure PIB_MI is set

Create an Arc enabled Dev Cluster

# set MY_CLUSTER
export MY_CLUSTER=central-tx-atx-$MY_BRANCH

# create an arc enabled cluster
# it will take about 2 minutes to create the VM
flt create cluster -c $MY_CLUSTER --arc

Update Git Repo

  • CI-CD generates the deployment manifests
    • Wait for CI-CD to complete (usually about 30 seconds)
# update the git repo after ci-cd completes
git pull

# add ips to repo
git add ips
git commit -am "added ips"
git push

Verify the Cluster Setup

# check the setup for "complete"
# rerun as necessary
flt check setup

# optional - use the Linux watch command
# press ctl-c after "complete"
watch flt check setup

Deploy IMDb App

  • Deploy IMDb app to Arc enabled K3d cluster

    # start in the apps/imdb directory
cd $PIB_BASE/apps/imdb

# deploy to central and west regions
flt targets add all
flt targets deploy

  • Wait for ci-cd to finish

  • Force cluster to sync

    # should see imdb added
git pull

# force flux to reconcile
flt sync

Validate IMDb app on Azure Arc

  • Get Azure Arc bearer token by running flt az arc-token
  • Login to Azure Portal and navigate to Azure Arc service
  • Click on Kubernetes clusters from the left nav and select your cluster
  • Click on Workloads from the left nav and place bearer token retrieved earlier
  • Validate the IMDb app running on the cluster

Delete Your Cluster

  • Once you're finished with the workshop and experimenting, delete your cluster

    # start in the root of your repo
cd $PIB_BASE
git pull

# delete azure resource
flt delete $MY_CLUSTER

# remove ips file
rm ips

# reset the targets
cd apps/imdb
flt targets clear
cd ../..

# update the repo
git commit -am "deleted cluster"
git push
