description: alibabab sentinel-dashboard chart for Kubernetes
4+
5+
# A chart can be either an 'application' or a 'library' chart.
6+
#
7+
# Application charts are a collection of templates that can be packaged into versioned archives
8+
# to be deployed.
9+
#
10+
# Library charts provide useful utilities or functions for the chart developer. They're included as
11+
# a dependency of application charts to inject those utilities and functions into the rendering
12+
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
13+
type: application
14+
15+
# This is the chart version. This version number should be incremented each time you make changes
16+
# to the chart and its templates, including the app version.
17+
version: 0.1.0
18+
19+
# This is the version number of the application being deployed. This version number should be
20+
# incremented each time you make changes to the application.

1. Get the application URL by running these commands:
25+
export NODE_PORT=$(kubectl get -o jsonpath="{.spec.ports[0].nodePort}" services sentinel-dashboard)
26+
export NODE_IP=$(kubectl get nodes -o jsonpath="{.items[0].status.addresses[0].address}")
27+
echo http://$NODE_IP:$NODE_PORT
28+
```
29+
30+
查看kubernetes对象
31+
```shell
