# NodeJS
|
||||||
|
|
||||||
|
[NodeJS](https://www.nodejs.org) The MEAN stack is MongoDB, Express.js, Angular, and Node.js. Because all components of the MEAN stack support programs written in JavaScript, MEAN applications can be written in one language for both server-side and client-side execution environments.
|
||||||
|
|
||||||
|
## TL;DR;
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ helm install incubator/mean
|
||||||
|
```
|
||||||
|
|
||||||
|
## Introduction
|
||||||
|
|
||||||
|
This chart bootstraps a [NodeJS](https://github.com/bitnami/bitnami-docker-node) and a [MongoDB](https://github.com/bitnami/bitnami-docker-mongodb) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
|
||||||
|
|
||||||
|
It clones and deploys a Node.js application from a git repository. Defaults to a demo MEAN application: https://github.com/scotch-io/node-todo.git
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
- Kubernetes 1.4+ with Beta APIs enabled
|
||||||
|
- PV provisioner support in the underlying infrastructure
|
||||||
|
|
||||||
|
## Installing the Chart
|
||||||
|
|
||||||
|
To install the chart with the release name `my-release`:
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ helm install --name my-release incubator/mean
|
||||||
|
```
|
||||||
|
|
||||||
|
The command deploys Node.js on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation. Also includes support for MongoDB chart out of the box.
|
||||||
|
|
||||||
|
Due that the Helm Chart clones the application on the /app volume while the container is initializing, a persistent volume is not required.
|
||||||
|
|
||||||
|
> **Tip**: List all releases using `helm list`
|
||||||
|
|
||||||
|
## Uninstalling the Chart
|
||||||
|
|
||||||
|
To uninstall/delete the `my-release` deployment:
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ helm delete my-release
|
||||||
|
```
|
||||||
|
|
||||||
|
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
The following tables lists the configurable parameters of the NodeJS chart and their default values.
|
||||||
|
|
||||||
|
| Parameter | Description | Default |
|
||||||
|
|------------------------------------|-------------------------------------|-----------------------------------------------------------|
|
||||||
|
| `image` | NodeJS image | `bitnami/node:{VERSION}` |
|
||||||
|
| `imagePullPolicy` | Image pull policy | `IfNotPresent` |
|
||||||
|
| `repository` | Repo of the application | `https://github.com/scotch-io/node-todo.git` |
|
||||||
|
| `revision` | Revision to checkout | `master` |
|
||||||
|
| `config` | Contents of the config file for app | `See repo file config/database.js` |
|
||||||
|
| `configfile` | Filename of config file for app | `database.js` |
|
||||||
|
| `mongodb.mongodbRootPassword` | MongoDB admin password | `nil` |
|
||||||
|
| `mongodb.mongodbUsername` | MongoDB username | `nil` |
|
||||||
|
| `mongodb.mongodbPassword` | MongoDB username password | `nil` |
|
||||||
|
| `mongodb.mongodbDatabase` | MongoDB database name | `nil` |
|
||||||
|
| `mongodb.persistence.enabled` | MongoDB Persistent Volume enabled? | `false` |
|
||||||
|
| `mongodb.persistence.storageClass` | Type of storage for PVC | `default` |
|
||||||
|
| `mongodb.persistence.accessMode` | Type of access mode for PVC | `ReadWriteOnce` |
|
||||||
|
| `mongodb.persistence.size` | Disk size | `8Gi` |
|
||||||
|
| `serviceType` | Kubernetes Service type | `LoadBalancer` |
|
||||||
|
| `resources` | CPU/Memory resource requests/limits | Memory: `512Mi`, CPU: `300m` |
|
||||||
|
| `persistence.enabled` | NodeJS persistence enabled? | `false` |
|
||||||
|
| `persistence.storageClass` | Type of storage for PVC | If defined: |
|
||||||
|
| `volume.beta.kubernetes.io/storage-class: <storageClass>` |
|
||||||
|
| Defaults: |
|
||||||
|
| `volume.alpha.kubernetes.io/storage-class: default` |
|
||||||
|
|--------------------------------------------------------------------------------------------------------------------------------------|
|
||||||
|
|
||||||
|
The above parameters map to the env variables defined in [bitnami/node](http://github.com/bitnami/bitnami-docker-node). For more information please refer to the [bitnami/node](http://github.com/bitnami/bitnami-docker-node) image documentation.
|
||||||
|
|
||||||
|
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ helm install --name my-release \
|
||||||
|
--set repository=https://github.com/scotch-io/node-todo.git,mongodb.mongodbRootPassword=secretpassword \
|
||||||
|
incubator/mean
|
||||||
|
```
|
||||||
|
|
||||||
|
The above command clones the remote git repository to the `/app/` directory of the container. Additionally it sets the MongoDB `root` user password to `secretpassword`.
|
||||||
|
|
||||||
|
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ helm install --name my-release -f values.yaml incubator/mean
|
||||||
|
```
|
||||||
|
|
||||||
|
> **Tip**: You can use the default [values.yaml](values.yaml)
|
||||||
|
|
||||||
|
## Persistence
|
||||||
|
|
||||||
|
The [Bitnami NodeJS](https://github.com/bitnami/bitnami-docker-node) image stores the NodeJS application and configurations at the `/app` path of the container.
|
||||||
|
This storage is ephemeral and it will disappear when the pods are taken away
|
||||||
|
|
||||||
|
Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube.
|
||||||
|
See the [Configuration](#configuration) section to configure the PVC or to disable persistence.

# MongoDB
|
||||||
|
|
||||||
|
[MongoDB](https://www.mongodb.com/) is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas, making the integration of data in certain types of applications easier and faster.
|
||||||
|
|
||||||
|
## TL;DR;
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm install stable/mongodb
|
||||||
|
```
|

|
|
||||||
|
## Introduction
|
||||||
|
|
||||||
|
This chart bootstraps a [MongoDB](https://github.com/bitnami/bitnami-docker-mongodb) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
- Kubernetes 1.4+ with Beta APIs enabled
|
||||||
|
- PV provisioner support in the underlying infrastructure
|
||||||

|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm install --name my-release stable/mongodb
|
||||||
|
```
|
||||||
|
|
||||||
|
The command deploys MongoDB on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
|
||||||
|
|
||||||
|
> **Tip**: List all releases using `helm list`
|
||||||
|
|
||||||
|
## Uninstalling the Chart
|
||||||
|
|
||||||
|
To uninstall/delete the `my-release` deployment:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm delete my-release
|
||||||
|
```
|
||||||
|
|
||||||
|
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
The following tables lists the configurable parameters of the MongoDB chart and their default values.
|
||||||
|
|
||||||
|
| Parameter | Description | Default |
|
||||||
|
|----------------------------|-------------------------------------|----------------------------------------------------------|
|
||||||
|
| `image` | MongoDB image | `bitnami/mongodb:{VERSION}` |
|
||||||
|
| `imagePullPolicy` | Image pull policy | `Always` if `imageTag` is `latest`, else `IfNotPresent`. |
|
||||||
|
| `mongodbRootPassword` | MongoDB admin password | `nil` |
|
||||||
|
| `mongodbUsername` | MongoDB custom user | `nil` |
|
||||||
|
| `mongodbPassword` | MongoDB custom user password | `nil` |
|
||||||
|
| `mongodbDatabase` | Database to create | `nil` |
|
||||||
|
| `serviceType` | Kubernetes Service type | `ClusterIP` |
|
||||||
|
| `persistence.enabled` | Use a PVC to persist data | `true` |
|
||||||
|
| `persistence.storageClass` | Storage class of backing PVC | `nil` (uses alpha storage class annotation) |
|
||||||
|
| `persistence.accessMode` | Use volume as ReadOnly or ReadWrite | `ReadWriteOnce` |
|
||||||
|
| `persistence.size` | Size of data volume | `8Gi` |
|
||||||
|
|
||||||
|
The above parameters map to the env variables defined in [bitnami/mongodb](http://github.com/bitnami/bitnami-docker-mongodb). For more information please refer to the [bitnami/mongodb](http://github.com/bitnami/bitnami-docker-mongodb) image documentation.
|
||||||
|
|
||||||
|
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm install --name my-release \
|
||||||
|
--set mongodbRootPassword=secretpassword,mongodbUsername=my-user,mongodbPassword=my-password,mongodbDatabase=my-database \
|
||||||
|
stable/mongodb
|
||||||
|
```
|
||||||
|
|
||||||
|
The above command sets the MongoDB `root` account password to `secretpassword`. Additionally it creates a standard database user named `my-user`, with the password `my-password`, who has access to a database named `my-database`.
|
||||||
|
|
||||||
|
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm install --name my-release -f values.yaml stable/mongodb
|
||||||
|
```
|
||||||
|
|
||||||
|
> **Tip**: You can use the default [values.yaml](values.yaml)
|
||||||
|
|
||||||
|
## Persistence
|
||||||
|
|
||||||
|
The [Bitnami MongoDB](https://github.com/bitnami/bitnami-docker-mongodb) image stores the MongoDB data and configurations at the `/bitnami/mongodb` path of the container.
|
||||||
|
|
||||||
|
The chart mounts a [Persistent Volume](http://kubernetes.io/docs/user-guide/persistent-volumes/) volume at this location. The volume is created using dynamic volume provisioning.

## 部署todo测试案例
|
我们可以看到Deployment和Service的名字前半截由两个随机的单词组成，最后才是我们在`values.yaml`中配置的值。
|
||||||
|
|
||||||
|
### 部署到kubernetes
|
||||||
|
|
||||||
|
在`mychart`目录下执行下面的命令将nginx部署到kubernetes集群上。
|
||||||
|
|
||||||
|
```bash
|
||||||
|
helm install .
|
||||||

|
|
||||||
|
NOTES:
|
||||||
|
1. Get the application URL by running these commands:
|
||||||
|
export POD_NAME=$(kubectl get pods --namespace default -l "app=eating-hound-mychart" -o jsonpath="{.items[0].metadata.name}")
|
||||||
|
echo "Visit http://127.0.0.1:8080 to use your application"
|
||||||
|
kubectl port-forward $POD_NAME 8080:80
|
||||||
|
```
|
||||||
|
|
||||||
|
现在nginx已经部署到kubernetes集群上，本地执行提示中的命令在本地主机上访问到nginx实例。
|
||||||
|
|
||||||
|
```bash
|
||||||
|
export POD_NAME=$(kubectl get pods --namespace default -l "app=eating-hound-mychart" -o jsonpath="{.items[0].metadata.name}")
|
||||||
|
echo "Visit http://127.0.0.1:8080 to use your application"
|
||||||
|
kubectl port-forward $POD_NAME 8080:80
|
||||||
|
```
|
||||||
|
|
||||||
|
在本地访问`http://127.0.0.1:8080`即可访问到nginx。
|
||||||
|
|
||||||
|
**查看部署的relaese**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm list
|
||||||
|

|
||||||

|
||||||
|
```
|
||||||
|
|
||||||
|
**删除部署的release**
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm delete eating-hound
|
||||||
|
release "eating-hound" deleted
|
||||||
|
```
|
||||||
|
|
||||||
|
### 打包分享
|
||||||
|
|
||||||
|
我们可以修改`Chart.yaml`中的helm chart配置信息，然后使用下列命令将chart打包成一个压缩文件。
|
||||||
|
|
||||||
|
```bash
|
||||||
|
helm package .
|
||||||
|
```
|
||||||
|
|
||||||
|
打包出`mychart-0.1.0.tgz`文件。
|
||||||
|
|
||||||
|
### 依赖
|
||||||
|
|
||||||
|
我们可以在`requirement.yaml`中定义应用所依赖的chart，例如定义对`mariadb`的依赖：
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
dependencies:
|
||||||
|
- name: mariadb
|
||||||
|
version: 0.6.0
|
||||||
|
repository: https://kubernetes-charts.storage.googleapis.com
|
||||||
|
```
|
||||||
|
|
||||||
|
使用`helm lint . `命令可以检查依赖和模板配置是否正确。
|
||||||
|
|
||||||
|
### 安装源
|
||||||
|
|
||||||
|
我们在前面安装chart可以通过HTTP server的方式提供。
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ helm serve
|
||||||
|
Regenerating index. This may take a moment.
|
||||||
|
Now serving you on 127.0.0.1:8879
|
||||||
|
```
|
||||||
|
|
||||||
|
访问`http://localhost:8879`可以看到刚刚安装的chart。
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
点击链接即可以下载chart的压缩包。
|
||||||
|
|
||||||
|
## 部署MEAN测试案例
|
||||||
|
|
||||||
|
MEAN是用来构建网站和web应用的免费开源的JavaScript软件栈，该软件栈包括MongoDB、Express.js、Angular和Node.js。
|
||||||
|
|
||||||
|

**修改mongodb chart配置**
|
||||||
|
|
||||||
|
将刚才下载的`charts/mongodb-0.4.17.tgz`给解压后，修改其中的配置：
|
||||||
|
|
||||||
|
- 将`persistence`下的`enabled`设置为false
|
||||||
|
- 将image修改为我们的私有镜像：sz-pg-oam-docker-hub-001.tendcloud.com/library/bitnami-mongodb:3.4.9-r1
|
||||||
|
|
||||||
|
执行`helm install --dry-run --debug .`确定模板无误。
|
||||||
|
|
||||||
|
将修改后的mongodb chart打包，在mongodb的目录下执行：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
helm package .
|
||||||
|
```
|
||||||
|
|
||||||
|
现在再访问前面启动的helm server `http://localhost:8879`将可以在页面上看到mongodb-0.4.17这个chart。
|
||||||
|
|
||||||
|
我们对官方chart配置做了如下修改后推送到了自己的chart仓库：
|
||||||
|
|
||||||
|
- `requirements.yaml`和`requirements.lock`文件中的`repository`为`http://localhost:8879`
|
||||||
|
- 将`values.yaml`中的`storageClass`设置为`null`
|
||||||
|
- 将`values.yaml`中的`Image`都改为私有镜像
|
||||||
|
- `repositroy`都设置为`http://localhost:8879`
|
||||||
|
|
||||||
|
**注**：因为我们没有使用PVC所以将所有的关于持久化存储的配置都设置为false了。
|
||||||
|
|
||||||
|
**部署MEAN**
|
||||||
|
|
||||||
|
在`mean`目录下执行：
|
||||||
|
|
||||||
|
```bash
|

NOTES:
|
||||||
|
|
||||||
|
Get the URL of your Node app by running:
|
||||||
|
|
||||||
|
export POD_NAME=$(kubectl get pods --namespace default -l "app=orbiting-platypus-mean" -o jsonpath="{.items[0].metadata.name}")
|
||||||
|
echo http://127.0.0.1:8080/
|
||||||
|
kubectl port-forward $POD_NAME 8080:80
|
||||||
|
```
|
||||||
|
|
||||||
|
这样MEAN软件栈就部署到你的kuberentes集群里面了（默认是在default namespace下）。
|
||||||
|
|
||||||
|
**验证检查**
|
||||||
|
|
||||||
|
为了验证MEAN是否安装成功过，可以使用`kubectl get pods`查看pod是否启动完成，会先启动mongodb的pod，然后启动MEAN中的4步init。
|
||||||
|
|
||||||
|
**访问Web UI**
|
||||||
|
|
||||||
|
在Ingress中增加如下配置：
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
- host: mean.jimmysong.io
|
||||||
|
http:
|
||||||
|
paths:
|
||||||
|
- backend:
|
||||||
|
serviceName: orbiting-platypus-mean
|
||||||
|
servicePort: 80
|
||||||
|
path: /
|
||||||
|
```
|
||||||
|
|
||||||
|
然后在页面中更新ingress:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
kubectl repalce -f ingress.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
关于Ingress配置请参考：[边缘节点配置](../practice/edge-node-configuration.md)
|
||||||
|
|
||||||
|
然后在本地的`/etc/hosts`文件中增加一条配置：
|
||||||
|
|
||||||
|
```Ini
|
||||||
|
172.20.0.119 mean.jimmysong.io
|
||||||
|
```
|
||||||
|
|
||||||
|
**注**：172.20.0.119即边缘节点的VIP。
|
||||||
|
|
||||||
|
因为该页面需要加载google的angularjs、还有两个css在国内无法访问，可以使用curl测试：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
curl mean.jimmysong.io
|
||||||
|
```
|
||||||
|
|
||||||
|
将会返回HTML内容：

访问 http://mean.jimmysong.io 可以看到如下界面，我在其中添加几条todo：
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
**注**：Todo中的文字来自*What does the fox say？*
|
||||||
|
|
||||||
|
测试完成后可以使用下面的命令将mean chart推送的本地chart仓库中。
|
||||||
|
|
||||||
|
在mean目录下执行：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
helm package .
|
||||||
|
```
|
||||||
|
|
||||||
|
再次刷新`http://localhost:8879`将可以看到如下三个chart：
|
||||||
|
|
||||||
|
- mean
|
||||||
|
- mean-0.1.3
|
||||||
|
- mongodb
|
||||||
|
- mongodb-0.4.17
|
||||||
|
- mychart
|
||||||
|
- mychart-0.1.0
