API (CRDs) & State Management (Controllers) With KubeVela

TODO: Intro

Setup

Watch Nix for Everyone: Unleash Devbox for Simplified Development if you are not familiar with Devbox. Alternatively, you can skip Devbox and install all the tools listed in devbox.json yourself.

Skip executing devbox shell if you are already inside the Shell from one of the previous episodes.

devbox shell

source .env

Watch The Future of Shells with Nushell! Shell + Data + Programming Language if you are not familiar with Nushell. Alternatively, you can inspect the dot.nu script and transform the instructions in it to Bash or ZShell if you prefer not to use that Nushell script.

./dot.nu setup idp_kubevela $HYPERSCALER

source .env

Do

cd cncf-demo-app

cp ../kubevela/$HYPERSCALER-sql.yaml apps/silly-demo-db.yaml

cp ../kubevela/$HYPERSCALER-sql-password.yaml \
    apps/silly-demo-db-password.yaml

cat apps/silly-demo-db-password.yaml

cat apps/silly-demo-db.yaml

kubectl --namespace production apply \
    --filename apps/silly-demo-db-password.yaml

kubectl --namespace production apply \
    --filename apps/silly-demo-db.yaml

kubectl get managed

cp ../kubevela/app.yaml apps/silly-demo.yaml

cat apps/silly-demo.yaml

kubectl --namespace production apply \
    --filename apps/silly-demo.yaml

kubectl --namespace production get all,ingresses

The Pod STATUS is ErrImagePull because there is no image. We'll fix that later.

vela delete silly-demo --yes

git add .

git commit -m "Apps"

git push

cd ..
