# Deploy services on Kubernetes
|
|
|
|
In Kubernetes, the service consists of two components,
|
|
|
|
1. Environments
|
|
2. Applications
|
|
|
|
And you can choose the storage in the application either NFS or Cinder provided by Openstack(used by [Pasta](http://paas-ta.kr))
|
|
|
|
# Prerequisites
|
|
|
|
## Install kustomize
|
|
|
|
If you are using kubectl 1.14 or later, it embeded kustomize. So please ignore this section.
|
|
I recommend that you install the latest version of [kubectl](https://kubectl.docs.kubernetes.io/installation/kubectl/) for your cluster instead of installing kustomize.
|
|
Even so, if you want to use kustomize, refer to [official kustomize doc](https://kustomize.io/).
|
|
|
|
# Deploy service
|
|
|
|
You must follow deployment order.
|
|
|
|
## Deployenvironments
|
|
|
|
```sh
|
|
$ kustomize build k8s/environments | kubectl apply -f -
|
|
```
|
|
or if you are using the kubectl only,
|
|
|
|
```sh
|
|
$ kubectl apply -k k8s/environments
|
|
```
|
|
|
|
## Deploy applications
|
|
|
|
If you want to use NFS as a main storage,
|
|
|
|
```sh
|
|
$ kustomize build k8s/stoage/nfs | kubectl apply -f -
|
|
```
|
|
|
|
or
|
|
|
|
```sh
|
|
$ kubectl apply -k k8s/stoage/nfs
|
|
```
|
|
|
|
In case of using Openstack storage(CINDER) as a main storage,
|
|
|
|
```sh
|
|
$ kustomize build k8s/stoage/openstack | kubectl apply -f -
|
|
```
|
|
|
|
or
|
|
|
|
```sh
|
|
$ kubectl apply -k k8s/stoage/openstack
|
|
```
|
|
|
|
# Shutdown service
|
|
|
|
Simply apply deployment in reverse order.
|
|
|
|
If you are using nfs,
|
|
|
|
```sh
|
|
$ kustomize build k8s/environments | kubectl delete -f -
|
|
$ kustomize build k8s/stoage/nfs | kubectl delete -f - --wait
|
|
```
|
|
|
|
or
|
|
|
|
```sh
|
|
$ kubectl delete -k k8s/environments
|
|
$ kubectl delete -k k8s/stoage/nfs --wait
|
|
```
|
|
|
|
The case of openstack is similar, so it is omitted.
