K8S MongoDB Operator and Statfulsets

Mostly the same as recent Minio Statefulsets notes.

Good reads as follow.

First, Set up NFS Server from my link below.

Argo CD, Traefik, Let’s Encrypt on GCP Part 1

Then, Set up the folder for MongoDB. Navigate to folder /mnt/nfs_share and create folder mongodb, mongodb0, mongodb1, log0, log1

cd /mnt/nfs_share
mkdir mongodb
cd mongodb
mkdir mongodb0
mkdir mongodb1
mkdir log0
mkdir log1

chmod and chown to nobody:nogroup

chmod 777 mongodb0
chmod 777 mongodb1
chmod 777 log0
chmod 777 log1
sudo chown nobody:nogroup mongodb0
sudo chown nobody:nogroup mongodb1
sudo chown nobody:nogroup log0
sudo chown nobody:nogroup log1

This is my repo.

mongodb · main · art Krisada / argocd-test · GitLab

Next, apply yml file to deploy MongoDB Operator and StatefulSets. You must change NFS Server IP to yours (in pv.yml). You must change External IP to yours(in statefulsets-template.yml). You can change the port number if you like(in service.yml). This is for example only.

statefulsets-template.yml

service.yml

Next, Config traefik to expose MongoDB to outside world.

From my traefik repo.

traefik · main · art Krisada / argocd-test · GitLab

04-traefik-service.yml

05-traefik.yml

After Deploy MongoDB and Traefik, You can access MongoDB at your ip:port from your client like Robo3T

My mongodb-0 is primary that can read/write and mongodb-1 is read only.
