QUESTION
Error:
Node mongodb-primary.ecs.endpoint did not become available
Details:
I have deployed MongoDB on AWS ECS using https://github.com/bitnami/bitnami-docker-mongodb as the Docker image with replica set feature which means that I have 2 more services running on the same EC2 instance apart from primary and those are secondary and arbiter.
Upon deployment, all 3 services start their task and the primary service's task keeps running successfully while secondary and arbiter service's tasks fail.
Here are the logs:
...ANSWER
Answered 2021-Nov-28 at 16:12Issue:
The replica set config was missing.
Solution:
To fix this, I logged into the primary instance using MongoDB Compass and then used mongosh to run the following command: rs.initiate(). Within a minute, other nodes (secondary and arbiter) registered themselves into the replicaset and primary became primary.
Output:
Below are the logs of the rs.status() command:

QUESTION
I have the helm chart mongodb installed on my k8s cluster (https://github.com/bitnami/charts/tree/master/bitnami/mongodb).
I also have kube-prometheus-stack installed on my k8s cluster. (https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack)
I've setup a grafana dashboard for mongodb which should pull in data from a prometheus data source. (https://grafana.com/grafana/dashboards/2583 )
However, my grafana dashboard is empty with no data.
I'm wondering if i have not configured something with the helm chart properly. Please see the mongodb helm chart below.
mognodb chart.yml

Answered 2021-Mar-17 at 00:40Installing prometheus using the "prometheus-community/kube-prometheus-stack" helm chart could be quite an extensive topic in itself considering the fact that it has a lot of configurable options.
As the helm chart comes with "prometheus operator", we have used PodMonitor and/or ServiceMonitor CRD's as they provide far more configuration options. Here's some documentation around that.
We've installed it with setting "prometheus.prometheusSpec.serviceMonitorSelector.matchLabels" with a label value. Something like this

Answered 2021-Jan-12 at 07:01I want to share my solution for this problem, so you can benefit from your turn. to link to the mongo image, you should update the docker-compose file, and leave the settings as-is. providing an environmental variable in the docker-compose will re-write the settings in the settings.json file, as the following:

QUESTION
I am using Bitnami MongoDB together with MongoDB Helm Chart (version 10.6.10, image tag being 3.6.17-ol-7-r26) to run a Mongo cluster in AWS under Kubernetes, which was initially created using the Helm chart. I am trying to get backups working using EBS Snapshots so that periodically whole volume from the primary MongoDB member is copied, which in case something happens could be restored to a new MongoDB installation (using the same Helm chart).
Currently I'm trying to get a backup process so that the snapshot would be put into a new volume, and a new Mongo namespace could be created in the same Kubernetes cluster, where the existing volume would be mounted. This works so that I'm able to create the Kubernetes volumes manually from the snapshot (Kubernetes Persistent Volume and Persistent Volume Claim) and link them with the MongoDB Helm chart (as those PV + PVC contain proper names), and start the Mongo server.
However, once the pods are running (primary, secondary and arbiter), the previously existing replica set is in place (old local database I guess) and obviously not working, as it's from the snapshot state.
Now I would wish to, following MongoDB documentation
- Destroy existing replica set
- Reset default settings on arbiter+slave
- Create replica set from primary/master (with data being in place for primary)
- Attach arbiter and slave to replica set to sync the data similar to what's in the docs.
Checking into the state from primary, I get

Answered 2020-Dec-09 at 15:17When using existing data to restore Mongo cluster created with bitnami/mongodb helm chart you will need to set some values on the installation command that ensure all the configuration to be in sync between configmaps, secrets, etc and the data stored in this volume.
First, in addition to --set architecture=replicaset you must add an existing PVC to the chart:
