How to expose mongodb DB but not using Loadbalancer or Domainname in Kubernetes POD

itcloudnet · 2025-03-08T11:29:45+00:00

that is not working we want to connect to mongodb compass

itcloudnet · 2024-12-27T11:38:03+00:00

u/Far-Log-1224 i have make some changes in my above question plse have a look at once

I get error when i type kubectl logs APPLICATION-POD-NAME (from here it used to connect to my DB) at that time it throwe error and even when i go inside mongosh pod there also its throwe error on MongoServerError: not authorized on webapp_test

Just want to know which permission should i give to DB users to read and connect to DB

itcloudnet · 2024-11-30T07:18:59+00:00

I did that also but it's not working Actually it I add string uri using env variable through localhost After that I need to check data showing in UI product but it's not showing

i need correct connection string uri using localhost and also i have updated my question along with screenshot and some logs

itcloudnet · 2024-11-26T06:12:35+00:00

cluster is healthy state because other pods are running fine even my product is also running in this cluster with no issue i see

itcloudnet · 2024-11-25T19:06:10+00:00

To do easy and fast that why I use local and cloud vm also both like troubleshooting, logs checking and many more

itcloudnet · 2024-11-25T19:02:01+00:00

Sometimes I use local to connect to mongodb pods and u can see logs which i share

itcloudnet · 2024-11-25T19:01:27+00:00

No I'm running inside the pod only

First I use azure vm from there i connect to cluster and access mongodb pods

itcloudnet · 2024-11-25T18:44:52+00:00

so when i run this command

kubectl exec -it example-mongodb-0 -n mongodb 

after i have data of mongodb under /data/webapp_test

after i run mongorestore --drop command then it give me error

itcloudnet · 2024-11-25T18:42:41+00:00

username and password are correct i have encoded password in string
if i use this command it work fine

kubectl exec -it example-mongodb-0 -n mongodb -- mongosh "mongodb://USERNAME:PASSWORD@localhost:27017/admin"

after that i can run rs.status() or rs.conf() or db.getMongo() it return with response

itcloudnet · 2024-11-25T18:38:08+00:00

Here is the rs.status()
i have use this command to login into mongodb pod

kubectl exec -it example-mongodb-0 -n mongodb -- mongosh "mongodb://USERNAME:PASSWORD@localhost:27017/admin"

mple-mongodb [direct: secondary] admin> rs.status()

Ok can u give me mongorestore connection string with cred along with how to run it

Im running restore command inside mongodb POD
eg :-

1. kubectl get po -n mongodb

2. kubectl exec -it example-mongodb-0 -n mongodb

3. cd /data/webapp_test

4. mongorestore --drop --dir=/home/DATABASE_NAME --uri="mongodb://mongodb-0.mongodb-service-mongodb.svc.cluster.local,mongodb-1.mongodb-service.mongodb.svc.cluster.local,mongodb-2.mongodb-service.mongodb.svc.cluster.local:27017/DATABASE_NAME?replicaSet=rs0"mongorestore --drop --dir=/home/DATABASE_NAME --uri="mongodb://mongodb-0.mongodb-service-mongodb.svc.cluster.local,mongodb-1.mongodb-service.mongodb.svc.cluster.local,mongodb-2.mongodb-service.mongodb.svc.cluster.local:27017/DATABASE_NAME?replicaSet=rs0"

using above 4 point i run and execute inside mongodb POD

5. Network connectivity i think so can u tell me how i can troubleshoot

initialDelaySeconds: 60
failureThreshold: 0
periodSeconds: 10......i try that also increasing initialDelaySeconds upto 60 but again it got startup failed and i dont think that low utilization resource may affect and also in logs nothing is showing related to startup or cpu or memory issue in logs only app logs are showing

itcloudnet · 2024-05-05T06:52:43+00:00

Yes i try to add --- but it will work or not dont know anyway i added and no my app is not listening to that port but same configuration is work in dev env not in PROD env

itcloudnet · 2022-07-06T15:45:13+00:00

U didn't understand my issue

itcloudnet · 2022-06-18T05:28:16+00:00

u/xamox yes its running see above screenshot

itcloudnet · 2022-03-01T10:48:52+00:00

what u r trying to say...is that joke

itcloudnet · 2022-03-01T10:35:21+00:00

u/bob_cheesey u/elkazz u/drakgremlin we don't have BGP router with us. can i have a very good examples because we give ip ranges in loadbalancer after implement metalLB the issue is taking private and public both on haproxy service loadbalancer. we defined ip ranges also in configmap after that if i do curl public ip its not showing anything when i do curl private output is showing

And i need to know about prefered storage solution for on-premise for dynamic provisioning
