k8s

create namespace: kubectl create ns {name}
create deployment : kubectl {namespace} {create/apply} -f manifests/{service_name}
- example: kubectl -n{name} apply -f manifests/manifests/swagger.yaml
get service: kubectl -n{name} get service

deploy a service

write a yaml file to create a deployment.
create deploment: kubectl {namespace} create -f manifests/{service_name}
checking pod status: kubectl -n{name} get pod
checkout node: kuberctl get node
find a node and find hostname: kubectl describe node {nodeid} | grep hostname
go to [K8S dev], select Load Balancer product, paste the hostname and port predefined on the yaml file.
make sure your load balancer is running and ipv4 is up
checkout vip
go to [K8S dev] select DNS product, create a record with the vip
