Red Hat build of MicroShift

Use the manifests example

You can automatically deploy a BusyBox container on MicroShift by using kustomize manifests in the /etc/microshift/manifests directory.

Procedure

Create the BusyBox manifest files by running the following commands:

Define the directory location:

$ MANIFEST_DIR=/etc/microshift/manifests

Make the directory:
```
$ sudo mkdir -p ${MANIFEST_DIR}
```

Place the YAML file in the directory:

sudo tee ${MANIFEST_DIR}/busybox.yaml &>/dev/null <<EOF
apiVersion: v1
kind: Namespace
metadata:
  name: busybox
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: busybox
  namespace: busybox-deployment
spec:
  selector:
    matchLabels:
      app: busybox
  template:
    metadata:
      labels:
        app: busybox
    spec:
      containers:
      - name: busybox
        image: BUSYBOX_IMAGE
        command: [ "/bin/sh", "-c", "while true ; do date; sleep 3600; done;" ]
EOF

Next, create the kustomize manifest files by running the following commands:

Place the YAML file in the directory:

sudo tee ${MANIFEST_DIR}/kustomization.yaml &>/dev/null <<EOF
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: busybox
resources:
  - busybox.yaml
images:
  - name: BUSYBOX_IMAGE
    newName: busybox:1.35
EOF

Restart MicroShift to apply the manifests by running the following command:
```
$ sudo systemctl restart microshift
```
Apply the manifests and start the busybox pod by running the following command:
```
$ oc get pods -n busybox
```
