A Docker image for performing MongoDB backups to Google Cloud Storage
Up to 4.4.
docker run \
-e MONGODB_HOST=<db host> \
-e MONGODB_DB=<your db name> \

-e MONGODB_PASSWORD=<your secret> \
-e GCS_KEY_FILE_PATH=<path to GC service account key file> \

dazlabteam/mongodb-gc-backup
Edit your Docker Compose file, add new backup service:
db:
image: "mongo:4.4.6"
ports:
- "27017:27017"
environment:
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: secret
MONGO_INITDB_DATABASE: demo
...
backup:
image: dazlabteam/mongodb-gc-backup
environment:
MONGODB_HOST: db
MONGODB_DB: demo
MONGODB_USER: root
MONGODB_PASSWORD: secret
GCS_KEY_FILE_PATH: <path to GC service account key file>
GCS_BUCKET: <GC bucket name>
Then run
docker-compose -f <path to docker compose yaml> run --rm backup
or by specifying env variables via the command line:
docker-compose -f <path to docker compose yaml> run --rm \
-e MONGODB_HOST=<db host> \
-e MONGODB_DB=<your db name> \
-e MONGODB_USER=<your db username> \
-e MONGODB_PASSWORD=<your secret> \
-e GCS_KEY_FILE_PATH=<path to GC service account key file> \
-e GCS_BUCKET=<GC bucket name> \
backup
Create Kubernetes secret containing all the environment variables:
kubectl create secret generic mongodb-gc-backup \
--from-literal=MONGODB_HOST=<db host> \
--from-literal=MONGODB_DB=<your db name> \
--from-literal=MONGODB_USER=<your db username> \
--from-literal=MONGODB_PASSWORD=<your secret> \
--from-literal=GCS_KEY_FILE_PATH=<path to GC service account key file> \
--from-literal=GCS_BUCKET=<GC bucket name>
then create CronJob using the cronjob spec file from this repo:
kubectl apply -f mongodb-gc-backup.cronjob.yaml
By default, it will run every day at 00:00. To change this, edit cronjob and specify other schedule:
kubectl edit cronjob mongodb-gc-backup
