## TL;DR

```console
helm repo add my-repo https://charts.bitnami.com/bitnami
helm install my-release my-repo/mongodb
```

## Introduction

This chart bootstraps a [MongoDB(&reg;)](https://github.com/bitnami/containers/tree/main/bitnami/mongodb) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.19+
- Helm 3.2.0+
- PV provisioner support in the underlying infrastructure

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm repo add my-repo https://charts.bitnami.com/bitnami
helm install my-release my-repo/mongodb
```

The command deploys MongoDB(&reg;) on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) 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:

```console
helm delete my-release
```

The command removes all the Kubernetes components associated with the chart and deletes the release.

## Architecture

This chart allows installing MongoDB(&reg;) using two different architecture setups: `standalone` or `replicaset`. Use the `architecture` parameter to choose the one to use:

```console
architecture="standalone"
architecture="replicaset"
```

Refer to the [chart documentation for more information on each of these architectures](https://docs.bitnami.com/kubernetes/infrastructure/mongodb/get-started/understand-architecture/).

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
    --set auth.rootPassword=secretpassword,auth.username=my-user,auth.password=my-password,auth.database=my-database \
    my-repo/mongodb
```

The above command sets the MongoDB(&reg;) `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`.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml my-repo/mongodb
```

> **Tip**: You can use the default [values.yaml](values.yaml)

## Configuration and installation details

### [Rolling vs Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Customize a new MongoDB instance

The [Bitnami MongoDB(&reg;) image](https://github.com/bitnami/containers/tree/main/bitnami/mongodb) supports the use of custom scripts to initialize a fresh instance. In order to execute the scripts, two options are available:

- Specify them using the `initdbScripts` parameter as dict.
- Define an external Kubernetes ConfigMap with all the initialization scripts by setting the `initdbScriptsConfigMap` parameter. Note that this will override the previous option.

The allowed script extensions are `.sh` and `.js`.

### Replicaset: Access MongoDB(&reg;) nodes from outside the cluster

In order to access MongoDB(&reg;) nodes from outside the cluster when using a replicaset architecture, a specific service per MongoDB(&reg;) pod will be created. There are two ways of configuring external access:

- Using LoadBalancer services
- Using NodePort services.

Refer to the [chart documentation for more details and configuration examples](https://docs.bitnami.com/kubernetes/infrastructure/mongodb/configuration/configure-external-access-replicaset/).

### Add extra environment variables

To add extra environment variables (useful for advanced operations like custom init scripts), use the `extraEnvVars` property.

```yaml
extraEnvVars:
  - name: LOG_LEVEL
    value: error
```

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` properties.

### Use Sidecars and Init Containers

If additional containers are needed in the same pod (such as additional metrics or logging exporters), they can be defined using the `sidecars` config parameter. Similarly, extra init containers can be added using the `initContainers` parameter.

Refer to the chart documentation for more information on, and examples of, configuring and using [sidecars and init containers](https://docs.bitnami.com/kubernetes/infrastructure/mongodb/configuration/configure-sidecar-init-containers/).

## Persistence

The [Bitnami MongoDB(&reg;)](https://github.com/bitnami/containers/tree/main/bitnami/mongodb) image stores the MongoDB(&reg;) data and configurations at the `/bitnami/mongodb` path of the container.

The chart mounts a [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) at this location. The volume is created using dynamic volume provisioning.

If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/).

## Use custom Prometheus rules

Custom Prometheus rules can be defined for the Prometheus Operator by using the `prometheusRule` parameter.

Refer to the [chart documentation for an example of a custom rule](https://docs.bitnami.com/kubernetes/infrastructure/mongodb/administration/use-prometheus-rules/).

## Enable SSL/TLS

This chart supports enabling SSL/TLS between nodes in the cluster, as well as between MongoDB(&reg;) clients and nodes, by setting the `MONGODB_EXTRA_FLAGS` and `MONGODB_CLIENT_EXTRA_FLAGS` container environment variables, together with the correct `MONGODB_ADVERTISED_HOSTNAME`. To enable full TLS encryption, set the `tls.enabled` parameter to `true`.

Refer to the [chart documentation for more information on enabling TLS](https://docs.bitnami.com/kubernetes/infrastructure/mongodb/administration/enable-tls/).

### Set Pod affinity

This chart allows you to set your custom affinity using the `XXX.affinity` parameter(s). Find more information about Pod affinity in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, you can use the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `XXX.podAffinityPreset`, `XXX.podAntiAffinityPreset`, or `XXX.nodeAffinityPreset` parameters.

## Troubleshooting

Find more information about how to deal with common errors related to Bitnami's Helm charts in [this troubleshooting guide](https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues).

## Upgrading

If authentication is enabled, it's necessary to set the `auth.rootPassword` (also `auth.replicaSetKey` when using a replicaset architecture) when upgrading for readiness/liveness probes to work properly. When you install this chart for the first time, some notes will be displayed providing the credentials you must use under the 'Credentials' section. Please note down the password, and run the command below to upgrade your chart:

```console
helm upgrade my-release my-repo/mongodb --set auth.rootPassword=[PASSWORD] (--set auth.replicaSetKey=[REPLICASETKEY])
```

> Note: you need to substitute the placeholders [PASSWORD] and [REPLICASETKEY] with the values obtained in the installation notes.

### To 12.0.0

This major release renames several values in this chart and adds missing features, in order to be inline with the rest of assets in the Bitnami charts repository.

Affected values:

- `strategyType` is replaced by `updateStrategy`
- `service.port` is renamed to `service.ports.mongodb`
- `service.nodePort` is renamed to `service.nodePorts.mongodb`
- `externalAccess.service.port` is renamed to `externalAccess.hidden.service.ports.mongodb`
- `rbac.role.rules` is renamed to `rbac.rules`
- `externalAccess.hidden.service.port` is renamed ot `externalAccess.hidden.service.ports.mongodb`
- `hidden.strategyType` is replaced by `hidden.updateStrategy`
- `metrics.serviceMonitor.relabellings` is renamed to `metrics.serviceMonitor.relabelings`(typo fixed)
- `metrics.serviceMonitor.additionalLabels` is renamed to `metrics.serviceMonitor.labels`

Additionally also updates the MongoDB image dependency to it newest major, 5.0

### To 11.0.0

In this version, the mongodb-exporter bundled as part of this Helm chart was updated to a new version which, even it is not a major change, can contain breaking changes (from `0.11.X` to `0.30.X`).
Please visit the release notes from the upstream project at <https://github.com/percona/mongodb_exporter/releases>

### To 10.0.0

[On November 13, 2020, Helm v2 support formally ended](https://github.com/helm/charts#status-of-the-project). This major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.

[Learn more about this change and related upgrade considerations](https://docs.bitnami.com/kubernetes/infrastructure/mongodb/administration/upgrade-helm3/).

### To 9.0.0

MongoDB(&reg;) container images were updated to `4.4.x` and it can affect compatibility with older versions of MongoDB(&reg;). Refer to the following guides to upgrade your applications:

- [Standalone](https://docs.mongodb.com/manual/release-notes/4.4-upgrade-standalone/)
- [Replica Set](https://docs.mongodb.com/manual/release-notes/4.4-upgrade-replica-set/)

### To 8.0.0

- Architecture used to configure MongoDB(&reg;) as a replicaset was completely refactored. Now, both primary and secondary nodes are part of the same statefulset.
- Chart labels were adapted to follow the Helm charts best practices.
- This version introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
- Several parameters were renamed or disappeared in favor of new ones on this major version. These are the most important ones:
  - `replicas` is renamed to `replicaCount`.
  - Authentication parameters are reorganized under the `auth.*` parameter:
    - `usePassword` is renamed to `auth.enabled`.
    - `mongodbRootPassword`, `mongodbUsername`, `mongodbPassword`, `mongodbDatabase`, and `replicaSet.key` are now `auth.rootPassword`, `auth.username`, `auth.password`, `auth.database`, and `auth.replicaSetKey` respectively.
  - `securityContext.*` is deprecated in favor of `podSecurityContext` and `containerSecurityContext`.
  - Parameters prefixed with `mongodb` are renamed removing the prefix. E.g. `mongodbEnableIPv6` is renamed to `enableIPv6`.
  - Parameters affecting Arbiter nodes are reorganized under the `arbiter.*` parameter.

Consequences:

- Backwards compatibility is not guaranteed. To upgrade to `8.0.0`, install a new release of the MongoDB(&reg;) chart, and migrate your data by creating a backup of the database, and restoring it on the new release.

### To 7.0.0

From this version, the way of setting the ingress rules has changed. Instead of using `ingress.paths` and `ingress.hosts` as separate objects, you should now define the rules as objects inside the `ingress.hosts` value, for example:

```yaml
ingress:
  hosts:
  - name: mongodb.local
    path: /
```

### To 6.0.0

From this version, `mongodbEnableIPv6` is set to `false` by default in order to work properly in most k8s clusters, if you want to use IPv6 support, you need to set this variable to `true` by adding `--set mongodbEnableIPv6=true` to your `helm` command.
You can find more information in the [`bitnami/mongodb` image README](https://github.com/bitnami/containers/tree/main/bitnami/mongodb#readme).

### To 5.0.0

When enabling replicaset configuration, backwards compatibility is not guaranteed unless you modify the labels used on the chart's statefulsets.
Use the workaround below to upgrade from versions previous to 5.0.0. The following example assumes that the release name is `my-release`:

```console
kubectl delete statefulset my-release-mongodb-arbiter my-release-mongodb-primary my-release-mongodb-secondary --cascade=false
```

### Add extra deployment options

To add extra deployments (useful for advanced features like sidecars), use the `extraDeploy` property.

In the example below, you can find how to use a example here for a [MongoDB replica set pod labeler sidecar](https://github.com/combor/k8s-mongo-labeler-sidecar) to identify the primary pod and dynamically label it as the primary node:

```yaml
extraDeploy:
  - apiVersion: v1
    kind: Service
    metadata:
      name: mongodb-primary
      namespace: default
      labels:
        app.kubernetes.io/component: mongodb
        app.kubernetes.io/instance: mongodb
        app.kubernetes.io/managed-by: Helm
        app.kubernetes.io/name: mongodb
    spec:
      type: NodePort
      externalTrafficPolicy: Cluster
      ports:
        - name: mongodb-primary
          port: 30001
          nodePort: 30001
          protocol: TCP
          targetPort: mongodb
      selector:
        app.kubernetes.io/component: mongodb
        app.kubernetes.io/instance: mongodb
        app.kubernetes.io/name: mongodb
        primary: "true"
```
