MongoDB
MongoDB is a cross-platform document-oriented database. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas, making the integration of data in certain types of applications easier and faster.
TL;DR;
$ helm install stable/mongodb
Introduction
This chart bootstraps a MongoDB deployment on a Kubernetes cluster using the Helm package manager.
Prerequisites
- Kubernetes 1.4+ with Beta APIs enabled
- PV provisioner support in the underlying infrastructure
Installing the Chart
To install the chart with the release name my-release
:
$ helm install --name my-release stable/mongodb
The command deploys MongoDB on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.
Tip: List all releases using
helm list
Uninstalling the Chart
To uninstall/delete the my-release
deployment:
$ helm delete my-release
The command removes all the Kubernetes components associated with the chart and deletes the release.
Configuration
The following tables lists the configurable parameters of the MongoDB chart and their default values.
Parameter | Description | Default |
---|---|---|
image |
MongoDB image | bitnami/mongodb:{VERSION} |
imagePullPolicy |
Image pull policy | Always if imageTag is latest , else IfNotPresent . |
mongodbRootPassword |
MongoDB admin password | nil |
mongodbUsername |
MongoDB custom user | nil |
mongodbPassword |
MongoDB custom user password | nil |
mongodbDatabase |
Database to create | nil |
serviceType |
Kubernetes Service type | ClusterIP |
persistence.enabled |
Use a PVC to persist data | true |
persistence.storageClass |
Storage class of backing PVC | nil (uses alpha storage class annotation) |
persistence.accessMode |
Use volume as ReadOnly or ReadWrite | ReadWriteOnce |
persistence.size |
Size of data volume | 8Gi |
The above parameters map to the env variables defined in bitnami/mongodb. For more information please refer to the bitnami/mongodb image documentation.
Specify each parameter using the --set key=value[,key=value]
argument to helm install
. For example,
$ helm install --name my-release \
--set mongodbRootPassword=secretpassword,mongodbUsername=my-user,mongodbPassword=my-password,mongodbDatabase=my-database \
stable/mongodb
The above command sets the MongoDB root
account password to secretpassword
. Additionally it creates a standard database user named my-user
, with the password my-password
, who has access to a database named my-database
.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
$ helm install --name my-release -f values.yaml stable/mongodb
Tip: You can use the default values.yaml
Persistence
The Bitnami MongoDB image stores the MongoDB data and configurations at the /bitnami/mongodb
path of the container.
The chart mounts a Persistent Volume volume at this location. The volume is created using dynamic volume provisioning.
