Answer 1

this is my service his name is api
apiVersion: v1
kind: Service
metadata:
name: api
labels:
app: api
spec:
type: NodePort
ports:
- port: 8080
nodePort: 30001
targetPort: 8080
protocol: TCP
name: api
selector:
app: api
and this is my deployement
apiVersion: apps/v1
kind: Deployment
metadata:
labels:
app: api
name: api
spec:
selector:
matchLabels:
app: api
template:
metadata:
labels:
app: api
spec:
containers:
- name: api
image: einstore/einstore-core:0.1.1
env:
- name: APICORE_STORAGE_LOCAL_ROOT
value: "/home/einstore"
- name: APICORE_SERVER_NAME
value: "Einstore - Enterprise AppStore"
- name: APICORE_SERVER_MAX_UPLOAD_FILESIZE
value: "50"
- name: APICORE_DATABASE_HOST
value: "postgres"
- name: APICORE_DATABASE_USER
value: "einstore"
- name: APICORE_DATABASE_PASSWORD
value: "einstore"
- name: APICORE_DATABASE_DATABASE
value: "einstore"
- name: APICORE_DATABASE_PORT

- name: APICORE_DATABASE_LOGGING
value: "false"
- name: APICORE_JWT_SECRET
value: "secret"
- name: APICORE_STORAGE_S3_ENABLED
value: "false"
- name: APICORE_STORAGE_S3_BUCKET
value: "~"
- name: APICORE_STORAGE_S3_ACCESS_KEY
value: "~"
- name: APICORE_STORAGE_S3_REGION
value: "~"
- name: APICORE_STORAGE_S3_SECRET_KEY
value: "~"
- name: APICORE_SERVER_URL
value: "http://**.***.*.***:30001/"
when i try to replace the *** with my machine #ip Everything works,But what I need is to change that so that there is the name of the service so that I can deploy the app in any other machine
the first solution LGTM but i get this error
curl http://api.einstore:8080/
curl: (6) Could not resolve host: api.einstore
NB: einstore= the name of my namespace
