# Demo: hello app
|
||||
|
||||
This demo helps you to deploy an example hello app end-to-end using kustomize.
|
||||
|
||||
Steps:
|
||||
1. Create the resources files.
|
||||
3. Spin-up kubernetes cluster on local using [kind].
|
||||
4. Deploy the app using kapply and verify the status.
|
||||
|
||||
First define a place to work:
|
||||
|
||||
<!-- @makeWorkplace @testE2EAgainstLatestRelease-->
|
||||
```
|
||||
DEMO_HOME=$(mktemp -d)
|
||||
```
|
||||
|
||||
Alternatively, use
|
||||
|
||||
> ```
|
||||
> DEMO_HOME=~/hello
|
||||
> ```
|
||||
|
||||
## Establish the base
|
||||
|
||||
Let's run the [hello] service.
|
||||
|
||||
<!-- @createBase @testE2EAgainstLatestRelease-->
|
||||
```
|
||||
BASE=$DEMO_HOME/base
|
||||
mkdir -p $BASE
|
||||
OUTPUT=$DEMO_HOME/output
|
||||
mkdir -p $OUTPUT
|
||||
```
|
||||
|
||||
Now lets add a simple config map resource to the `base`
|
||||
|
||||
<!-- @createConfigMapYaml @testE2EAgainstLatestRelease-->
|
||||
```
|
||||
cat <<EOF >$BASE/configMap.yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: the-map
|
||||
data:
|
||||
altGreeting: "Good Morning!"
|
||||
enableRisky: "false"
|
||||
EOF
|
||||
```
|
||||
|
||||
Create `service.yaml` pointing to the deployment created above
|
||||
|
||||
<!-- @createServiceYaml @testE2EAgainstLatestRelease-->
|
||||
```
|
||||
cat <<EOF >$BASE/service.yaml
|
||||
kind: Service
|
||||
apiVersion: v1
|
||||
metadata:
|
||||
name: the-service
|
||||
spec:
|
||||
selector:
|
||||
deployment: hello
|
||||
type: LoadBalancer
|
||||
ports:
|
||||
- protocol: TCP
|
||||
port: 8666
|
||||
targetPort: 8080
|
||||
EOF
|
||||
```
|
||||
|
||||
Create a `grouping.yaml` resource. By this, you are defining the grouping of the current directory, `base`. Kustomize uses the unique label in this file to track any future state changes made to this directory. Make sure the label key is `kustomize.config.k8s.io/inventory-id` and give any unique label value and DO NOT change it in future.
|
||||
|
||||
<!-- @createGroupingYaml @testE2EAgainstLatestRelease-->
|
||||
```
|
||||
cat <<EOF >$BASE/grouping.yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: inventory-map
|
||||
labels:
|
||||
cli-utils.sigs.k8s.io/inventory-id: hello-app
|
||||
EOF
|
||||
```
|
||||
|
||||
## Run end-to-end tests
|
||||
|
||||
The following requires installation of [kind].
|
||||
|
||||
Delete any existing kind cluster and create a new one. By default the name of the cluster is "kind"
|
||||
<!-- @deleteAndCreateKindCluster @testE2EAgainstLatestRelease -->
|
||||
```
|
||||
kind delete cluster
|
||||
kind create cluster
|
||||
```
|
||||
|
||||
Use the kapply binary in MYGOBIN to apply a deployment and verify it is successful.
|
||||
<!-- @runHelloApp @testE2EAgainstLatestRelease -->
|
||||
```
|
||||
kapply apply -f $BASE;
|
||||
|
||||
```
|
||||
|
||||
Now let's replace the configMap with configMap2 apply the config, fetch and verify the status. This should delete the-map from deployment and add the-map2.
|
||||
<!-- @replaceConfigMapInHello @testE2EAgainstLatestRelease -->
|
||||
```
|
||||
cat <<EOF >$BASE/configMap2.yaml
|
||||
apiVersion: v1
|
||||
kind: ConfigMap
|
||||
metadata:
|
||||
name: the-map2
|
||||
data:
|
||||
altGreeting: "Good Evening!"
|
||||
enableRisky: "false"
|
||||
EOF
|
||||
|
||||
rm $BASE/configMap.yaml
|
||||
|
||||
kapply apply -f $BASE;
|
||||
|
||||
```
|
||||
|
||||
Clean-up the cluster
|
||||
<!-- @deleteKindCluster @testE2EAgainstLatestRelease -->
|
||||
```
|
||||
kind delete cluster
|
||||
```
