What is the best way to prevent loss of data whenever i restart the pods.
Each time i restart/rebuild the pods to reflect code changes i loos all the data in the database and i have to them in.
Please advice on the best practice
You should configure your database service to store the DB data on a persistent volume. That way it’ll survive being restarted.
How are you defining your application? If you share your manifest, we can make some suggestions.
I did that be choosing an external volume in docker-compose file.
There are times it does not delete, there are times it deletes all the data
I am not sure why that behaviour
Below is my docker compose file.
wserver: ## Nodejs Back-end
depends_on:
- mongodb
build: ./www
restart: unless-stopped
env_file: .env
ports:
- 8090:8090
environment:
- DB_HOST=********
- DB_USER=***************
- DB_PASSWORD=************
- DB_NAME=*****************
- DB_PORT=********************
stdin_open: true
tty: true
grace: ## Angular Front-End
depends_on:
- wserver
build: ./portal
restart: unless-stopped
env_file: .env
ports:
- 4201:4201
volumes:
** mongodb-data:**
Can you add the definition for your mongodb service? That’s the one that needs to be configured with a volume.
