설치?
# mywebserver 라는 이름으로 설치해보자.
helm install mywebserver bitnami/nginx
NAME: mywebserver
LAST DEPLOYED: Thu Jul 8 10:40:33 2021
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
** Please be patient while the chart is being deployed **
NGINX can be accessed through the following DNS name from within your cluster:
mywebserver-nginx.default.svc.cluster.local (port 80)
To access NGINX from outside the cluster, follow the steps below:
1. Get the NGINX URL by running these commands:
NOTE: It may take a few minutes for the LoadBalancer IP to be available.
Watch the status with: 'kubectl get svc --namespace default -w mywebserver-nginx'
export SERVICE_PORT=$(kubectl get --namespace default -o jsonpath="{.spec.ports[0].port}" services mywebserver-nginx)
export SERVICE_IP=$(kubectl get svc --namespace default mywebserver-nginx -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
echo "http://${SERVICE_IP}:${SERVICE_PORT}"
