17 Looking to use MongoDBreg; in production? Try [VMware Tanzu Application Catalog](https://bitnami.com/enterprise), the enterprise edition of Bitnami Application Catalog.
21 This chart bootstraps a [MongoDB(®)](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.
23 Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

31 ## Installing the Chart
33 To install the chart with the release name `my-release`:
36 helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/mongodb
39 > Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
41 The command deploys MongoDB(®) on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
43 > **Tip**: List all releases using `helm list`
45 ## Uninstalling the Chart
47 To uninstall/delete the `my-release` deployment:
50 helm delete my-release
53 The command removes all the Kubernetes components associated with the chart and deletes the release.
57 This chart allows installing MongoDB(®) using two different architecture setups: `standalone` or `replicaset`. Use the `architecture` parameter to choose the one to use:
60 architecture="standalone"
61 architecture="replicaset"
64 ### Standalone architecture
66 The *standalone* architecture installs a deployment (or StatefulSet) with one MongoDB® server (it cannot be scaled):
82 ### Replicaset architecture
84 The chart also supports the *replicaset* architecture with and without a MongoDB(®) Arbiter:
86 When the MongoDB(®) Arbiter is enabled, the chart installs two StatefulSets: A StatefulSet with N MongoDB(®) servers (organised with one primary and N-1 secondary nodes), and a StatefulSet with one MongoDB(®) arbiter node (it cannot be scaled).
89 ---------------- ---------------- ---------------- -------------
90 | MongoDB® 0 | | MongoDB® 1 | | MongoDB® N | | Arbiter |
91 | external svc | | external svc | | external svc | | svc |
92 ---------------- ---------------- ---------------- -------------
95 ---------------- ---------------- ---------------- --------------
96 | MongoDB® 0 | | MongoDB® 1 | | MongoDB® N | | MongoDB® |
97 | Server | | Server | | Server | | Arbiter |
98 | Pod | | Pod | | Pod | | Pod |
99 ---------------- ---------------- ---------------- --------------
100 primary secondary secondary
103 The PSA model is useful when the third Availability Zone cannot hold a full MongoDB(®) instance. The MongoDB(®) Arbiter as decision maker is lightweight and can run alongside other workloads.
105 > NOTE: An update takes your MongoDB(®) replicaset offline if the Arbiter is enabled and the number of MongoDB(®) replicas is two. Helm applies updates to the StatefulSets for the MongoDB(®) instance and the Arbiter at the same time so you lose two out of three quorum votes.
107 Without the Arbiter, the chart deploys a single statefulset with N MongoDB(®) servers (organised with one primary and N-1 secondary nodes).
110 ---------------- ---------------- ----------------
111 | MongoDB® 0 | | MongoDB® 1 | | MongoDB® N |
112 | external svc | | external svc | | external svc |
113 ---------------- ---------------- ----------------
116 ---------------- ---------------- ----------------
117 | MongoDB® 0 | | MongoDB® 1 | | MongoDB® N |
118 | Server | | Server | | Server |
119 | Pod | | Pod | | Pod |
120 ---------------- ---------------- ----------------
121 primary secondary secondary
124 There are no services load balancing requests between MongoDB(®) nodes; instead, each node has an associated service to access them individually.
126 > NOTE: Although the first replica is initially assigned the primary role, any of the secondary nodes can become the primary if it is down, or during upgrades. Do not make any assumption about what replica has the primary role. Instead, configure your MongoDB(®) client with the list of MongoDB(®) hostnames so it can dynamically choose the node to send requests.

719 --set auth.rootPassword=secretpassword,auth.username=my-user,auth.password=my-password,auth.database=my-database \
720 oci://REGISTRY_NAME/REPOSITORY_NAME/mongodb
723 > Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
725 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`.
727 > 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.
729 Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
732 helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/mongodb
735 > Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
736 > **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/mongodb/values.yaml)
738 ## Configuration and installation details
740 ### Resource requests and limits
742 Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.
744 To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).
746 ### [Rolling vs Immutable tags](https://docs.bitnami.com/tutorials/understand-rolling-tags-containers)
748 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.
750 Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
752 ### Customize a new MongoDB instance
754 The [Bitnami MongoDB(®) 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:
756 - Specify them using the `initdbScripts` parameter as dict.
757 - Define an external Kubernetes ConfigMap with all the initialization scripts by setting the `initdbScriptsConfigMap` parameter. Note that this will override the previous option.
759 The allowed script extensions are `.sh` and `.js`.
761 ### Replicaset: Access MongoDB(®) nodes from outside the cluster
763 In order to access MongoDB(®) nodes from outside the cluster when using a replicaset architecture, a specific service per MongoDB(®) pod will be created. There are two ways of configuring external access:
765 - Using LoadBalancer services
766 - Using NodePort services.
768 #### Use LoadBalancer services
770 Two alternatives are available to use *LoadBalancer* services:
772 - Use random load balancer IP addresses using an *initContainer* that waits for the IP addresses to be ready and discovers them automatically. An example deployment configuration is shown below:
775 architecture=replicaset
777 externalAccess.enabled=true
778 externalAccess.service.type=LoadBalancer
779 externalAccess.service.port=27017
780 externalAccess.autoDiscovery.enabled=true
781 serviceAccount.create=true
785 > NOTE: This option requires creating RBAC rules on clusters where RBAC policies are enabled.
787 - Manually specify the load balancer IP addresses. An example deployment configuration is shown below, with the placeholder EXTERNAL-IP-ADDRESS-X used in place of the load balancer IP addresses:
790 architecture=replicaset
792 externalAccess.enabled=true
793 externalAccess.service.type=LoadBalancer
794 externalAccess.service.port=27017
795 externalAccess.service.loadBalancerIPs[0]='EXTERNAL-IP-ADDRESS-1'
796 externalAccess.service.loadBalancerIPs[1]='EXTERNAL-IP-ADDRESS-2'
799 > NOTE: This option requires knowing the load balancer IP addresses, so that each MongoDB® node's advertised hostname is configured with it.
801 #### Use NodePort services
803 Manually specify the node ports to use. An example deployment configuration is shown below, with the placeholder NODE-PORT-X used in place of the node ports:
806 architecture=replicaset
808 externalAccess.enabled=true
809 externalAccess.service.type=NodePort
810 externalAccess.service.nodePorts[0]='NODE-PORT-1'
811 externalAccess.service.nodePorts[1]='NODE-PORT-2'
814 > NOTE: This option requires knowing the node ports that will be exposed, so each MongoDB® node's advertised hostname is configured with it.
816 The pod will try to get the external IP address of the node using the command `curl -s https://ipinfo.io/IP-ADDRESS` unless the `externalAccess.service.domain` parameter is set.
818 ### Bootstrapping with an External Cluster
820 This chart is equipped with the ability to bring online a set of Pods that connect to an existing MongoDB(®) deployment that lies outside of Kubernetes. This effectively creates a hybrid MongoDB(®) Deployment where both Pods in Kubernetes and Instances such as Virtual Machines can partake in a single MongoDB(®) Deployment. This is helpful in situations where one may be migrating MongoDB(®) from Virtual Machines into Kubernetes, for example. To take advantage of this, use the following as an example configuration:
826 host: external-mongodb-0.internal
829 :warning: To bootstrap MongoDB(®) with an external master that lies outside of Kubernetes, be sure to set up external access using any of the suggested methods in this chart to have connectivity between the MongoDB(®) members. :warning:
831 ### Add extra environment variables
833 To add extra environment variables (useful for advanced operations like custom init scripts), use the `extraEnvVars` property.
841 Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` properties.
843 ### Use Sidecars and Init Containers
845 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.
849 - name: your-image-name
851 imagePullPolicy: Always
857 If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter (where available), as shown in the example below:
867 > NOTE: This Helm chart already includes sidecar containers for the Prometheus exporters (where applicable). These can be activated by adding the `--enable-metrics=true` parameter at deployment time. The `sidecars` parameter should therefore only be used for any extra sidecar containers.
869 If additional init containers are needed in the same pod, they can be defined using the `initContainers` parameter. Here is an example:
873 - name: your-image-name
875 imagePullPolicy: Always
881 Learn more about [sidecar containers](https://kubernetes.io/docs/concepts/workloads/pods/) and [init containers](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/).
885 The [Bitnami MongoDB(®)](https://github.com/bitnami/containers/tree/main/bitnami/mongodb) image stores the MongoDB(®) data and configurations at the `/bitnami/mongodb` path of the container.
887 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.
889 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/).
891 ### Backup and restore MongoDB(R) deployments
893 Two different approaches are available to back up and restore Bitnami MongoDB® Helm chart deployments on Kubernetes:
895 - Back up the data from the source deployment and restore it in a new deployment using MongoDB® built-in backup/restore tools.
896 - Back up the persistent volumes from the source deployment and attach them to a new deployment using Velero, a Kubernetes backup/restore tool.
898 #### Method 1: Backup and restore data using MongoDB® built-in tools
900 This method involves the following steps:
902 - Use the *mongodump* tool to create a snapshot of the data in the source cluster.
903 - Create a new MongoDB® Cluster deployment and forward the MongoDB® Cluster service port for the new deployment.
904 - Restore the data using the *mongorestore* tool to import the backup to the new cluster.
906 > NOTE: Under this approach, it is important to create the new deployment on the destination cluster using the same credentials as the original deployment on the source cluster.
908 #### Method 2: Back up and restore persistent data volumes
910 This method involves copying the persistent data volumes for the MongoDB® nodes and reusing them in a new deployment with [Velero](https://velero.io/), an open source Kubernetes backup/restore tool. This method is only suitable when:
912 - The Kubernetes provider is [supported by Velero](https://velero.io/docs/latest/supported-providers/).
913 - Both clusters are on the same Kubernetes provider, as this is a requirement of [Velero's native support for migrating persistent volumes](https://velero.io/docs/latest/migration-case/).
914 - The restored deployment on the destination cluster will have the same name, namespace, topology and credentials as the original deployment on the source cluster.
916 This method involves the following steps:
918 - Install Velero on the source and destination clusters.
919 - Use Velero to back up the PersistentVolumes (PVs) used by the deployment on the source cluster.
920 - Use Velero to restore the backed-up PVs on the destination cluster.
921 - Create a new deployment on the destination cluster with the same chart, deployment name, credentials and other parameters as the original. This new deployment will use the restored PVs and hence the original data.
923 Refer to our detailed [tutorial on backing up and restoring MongoDB® chart deployments on Kubernetes](https://docs.bitnami.com/tutorials/backup-restore-data-mongodb-kubernetes/), which covers both these approaches, for more information.
925 ### Use custom Prometheus rules
927 Custom Prometheus rules can be defined for the Prometheus Operator by using the `prometheusRule` parameter. A basic configuration example is shown below:
937 - alert: HighRequestLatency
938 expr: job:request_latency_seconds:mean5m{job="myjob"} > 0.5
943 summary: High request latency
948 This chart supports enabling SSL/TLS between nodes in the cluster, as well as between MongoDB(®) 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`.
950 #### Generate the self-signed certificates via pre-install Helm hooks
952 The `secrets-ca.yaml` file utilizes the Helm "pre-install" hook to ensure that the certificates will only be generated on chart install.
954 The `genCA()` function will create a new self-signed x509 certificate authority. The `genSignedCert()` function creates an object with the certificate and key, which are base64-encoded and used in a YAML-like object. The `genSignedCert()` function is passed the CN, an empty IP list (the nil part), the validity and the CA created previously.
956 A Kubernetes Secret is used to hold the signed certificate created above, and the `initContainer` sets up the rest. Using Helm's hook annotations ensures that the certificates will only be generated on chart install. This will prevent overriding the certificates if the chart is upgraded.
960 To use your own CA, set `tls.caCert` and `tls.caKey` with appropriate base64 encoded data. The `secrets-ca.yaml` file will utilize this data to create the Secret.
962 > NOTE: Currently, only RSA private keys are supported.
964 #### Access the cluster
966 To access the cluster, enable the init container which generates the MongoDB(®) server/client PEM key needed to access the cluster. Please be sure to include the `$my_hostname` section with your actual hostname, and the alternative hostnames section should contain the hostnames that should be allowed access to the MongoDB(®) replicaset. Additionally, if external access is enabled, the load balancer IP addresses are added to the alternative names list.
968 > NOTE: You will be generating self-signed certificates for the MongoDB(®) deployment. The init container generates a new MongoDB(®) private key which will be used to create a Certificate Authority (CA) and the public certificate for the CA. The Certificate Signing Request will be created as well and signed using the private key of the CA previously created. Finally, the PEM bundle will be created using the private key and public certificate. This process will be repeated for each node in the cluster.
970 #### Start the cluster
972 After the certificates have been generated and made available to the containers at the correct mount points, the MongoDB(®) server will be started with TLS enabled. The options for the TLS mode will be one of `disabled`, `allowTLS`, `preferTLS`, or `requireTLS`. This value can be changed via the `MONGODB_EXTRA_FLAGS` field using the `tlsMode` parameter. The client should now be able to connect to the TLS-enabled cluster with the provided certificates.
976 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).
978 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.
982 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).
986 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:
989 helm upgrade my-release oci://REGISTRY_NAME/REPOSITORY_NAME/mongodb --set auth.rootPassword=[PASSWORD] (--set auth.replicaSetKey=[REPLICASETKEY])
992 > Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
993 > Note: you need to substitute the placeholders [PASSWORD] and [REPLICASETKEY] with the values obtained in the installation notes.
997 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.
1001 - `strategyType` is replaced by `updateStrategy`
1002 - `service.port` is renamed to `service.ports.mongodb`
1003 - `service.nodePort` is renamed to `service.nodePorts.mongodb`
1004 - `externalAccess.service.port` is renamed to `externalAccess.hidden.service.ports.mongodb`
1005 - `rbac.role.rules` is renamed to `rbac.rules`
1006 - `externalAccess.hidden.service.port` is renamed ot `externalAccess.hidden.service.ports.mongodb`
1007 - `hidden.strategyType` is replaced by `hidden.updateStrategy`
1008 - `metrics.serviceMonitor.relabellings` is renamed to `metrics.serviceMonitor.relabelings`(typo fixed)
1009 - `metrics.serviceMonitor.additionalLabels` is renamed to `metrics.serviceMonitor.labels`
1011 Additionally also updates the MongoDB image dependency to it newest major, 5.0
1015 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`).
1016 Please visit the release notes from the upstream project at <https://github.com/percona/mongodb_exporter/releases>
1020 [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.
1024 MongoDB(®) container images were updated to `4.4.x` and it can affect compatibility with older versions of MongoDB(®). Refer to the following guides to upgrade your applications:
1026 - [Standalone](https://docs.mongodb.com/manual/release-notes/4.4-upgrade-standalone/)
1027 - [Replica Set](https://docs.mongodb.com/manual/release-notes/4.4-upgrade-replica-set/)
1031 - Architecture used to configure MongoDB(®) as a replicaset was completely refactored. Now, both primary and secondary nodes are part of the same statefulset.
1032 - Chart labels were adapted to follow the Helm charts best practices.
1033 - 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.
1034 - Several parameters were renamed or disappeared in favor of new ones on this major version. These are the most important ones:
1035 - `replicas` is renamed to `replicaCount`.
1036 - Authentication parameters are reorganized under the `auth.*` parameter:
1037 - `usePassword` is renamed to `auth.enabled`.
1038 - `mongodbRootPassword`, `mongodbUsername`, `mongodbPassword`, `mongodbDatabase`, and `replicaSet.key` are now `auth.rootPassword`, `auth.username`, `auth.password`, `auth.database`, and `auth.replicaSetKey` respectively.
1039 - `securityContext.*` is deprecated in favor of `podSecurityContext` and `containerSecurityContext`.
1040 - Parameters prefixed with `mongodb` are renamed removing the prefix. E.g. `mongodbEnableIPv6` is renamed to `enableIPv6`.
1041 - Parameters affecting Arbiter nodes are reorganized under the `arbiter.*` parameter.
1045 - Backwards compatibility is not guaranteed. To upgrade to `8.0.0`, install a new release of the MongoDB(®) chart, and migrate your data by creating a backup of the database, and restoring it on the new release.
1049 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:
1054 - name: mongodb.local
1060 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.
1061 You can find more information in the [`bitnami/mongodb` image README](https://github.com/bitnami/containers/tree/main/bitnami/mongodb#readme).
1065 When enabling replicaset configuration, backwards compatibility is not guaranteed unless you modify the labels used on the chart's statefulsets.
1066 Use the workaround below to upgrade from versions previous to 5.0.0. The following example assumes that the release name is `my-release`:
1069 kubectl delete statefulset my-release-mongodb-arbiter my-release-mongodb-primary my-release-mongodb-secondary --cascade=false
1072 ### Add extra deployment options
1074 To add extra deployments (useful for advanced features like sidecars), use the `extraDeploy` property.
1076 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:
1083 name: mongodb-primary
1086 app.kubernetes.io/component: mongodb
1087 app.kubernetes.io/instance: mongodb
1088 app.kubernetes.io/managed-by: Helm
1089 app.kubernetes.io/name: mongodb
1092 externalTrafficPolicy: Cluster
1094 - name: mongodb-primary
1100 app.kubernetes.io/component: mongodb
1101 app.kubernetes.io/instance: mongodb
1102 app.kubernetes.io/name: mongodb
