# Stan's Robot Shop
|
|
|
|
Use this helm chart to customise your install of Stan's Robot Shop.
|
|
|
|
### Helm v2.x
|
|
|
|
```shell
|
|
$ helm install --name robot-shop --namespace robot-shop .
|
|
```
|
|
|
|
### Helm v3.x
|
|
|
|
```bash
|
|
$ kubectl create ns robot-shop
|
|
$ helm install robot-shop --namespace robot-shop .
|
|
```
|
|
|
|
## Images
|
|
|
|
By default the images are pulled from Docker Hub. Setting `image.repo` this can be changed, for example:
|
|
|
|
```shell
|
|
$ helm install --set image.repo=eu.gcr.io/acme ...
|
|
```
|
|
|
|
Will pull images from the European Google registry project `acme`.
|
|
|
|
By default the latest version of the images is pulled. A specific version can be used:
|
|
|
|
```shell
|
|
$ helm install --set image.version=0.1.2 ...
|
|
```
|
|
|
|
It is recommened to always use the latest version.
|
|
|
|
## Pod Security Policy
|
|
|
|
If you wish to enable [PSP](https://kubernetes.io/docs/concepts/policy/pod-security-policy/)
|
|
|
|
```shell
|
|
$ helm install --set psp.enabled=true ...
|
|
```
|
|
|
|
## Payment Gateway
|
|
|
|
By default the `payment` service uses https://www.paypal.com as the pseudo payment provider. The code only does a HTTP GET against this url. You can use a different url.
|
|
|
|
```shell
|
|
$ helm install --set payment.gateway=https://foobar.com ...
|
|
```
|
|
|
|
## Website Monitoring / End-User Monitoring
|
|
|
|
Optionally Website Monitoring / End-User Monitoring can be enabled for the web pages. Take a look at the [documentation](https://docs.instana.io/website_monitoring/) to see how to get a key and an endpoint url.
|
|
|
|
```shell
|
|
$ helm install \
|
|
--set eum.key=xxxxxxxxx \
|
|
--set eum.url=https://eum-eu-west-1.instana.io \
|
|
...
|
|
```
|
|
|
|
## Use with Minis
|
|
|
|
When running on `minishift` or `minikube` set `web.nodeport` to true. The store will then be available on the IP address of your mini and node port of the web service.
|
|
|
|
```shell
|
|
$ mini[kube|shift] ip
|
|
192.168.66.101
|
|
$ kubectl get svc web
|
|
```
|
|
|
|
Combine the IP and port number to make the URL `http://192.168.66.101:32145`
|
|
|
|
### MiniShift
|
|
|
|
Openshift is like K8s but not K8s. Set `openshift` to true or things will break. See the notes and scripts in the OpenShift directory of this repo.
|
|
|
|
```shell
|
|
$ helm install robot-shop --set openshift=true helm
|
|
```
|
|
|
|
