PostgreSQL is an object-relational database management system (ORDBMS) with an emphasis on extensibility and on standards-compliance.
For HA, please see this repo
$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-release bitnami/postgresqlThis chart bootstraps a PostgreSQL deployment on a Kubernetes cluster using the Helm package manager.
Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the BKPR.
- Kubernetes 1.12+
- Helm 2.12+ or Helm 3.0-beta3+
- PV provisioner support in the underlying infrastructure
To install the chart with the release name my-release:
$ helm install my-release bitnami/postgresqlThe command deploys PostgreSQL on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.
Tip: List all releases using
helm list
To uninstall/delete the my-release deployment:
$ helm delete my-releaseThe command removes all the Kubernetes components associated with the chart and deletes the release.
The following tables lists the configurable parameters of the PostgreSQL chart and their default values.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
$ helm install my-release \
--set postgresqlPassword=secretpassword,postgresqlDatabase=my-database \
bitnami/postgresqlThe above command sets the PostgreSQL postgres account password to secretpassword. Additionally it creates 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 my-release -f values.yaml bitnami/postgresqlTip: You can use the default values.yaml
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.
This chart includes a values-production.yaml file where you can find some parameters oriented to production configuration in comparison to the regular values.yaml. You can use this file instead of the default one.
- Enable replication:
- replication.enabled: false
+ replication.enabled: true- Number of slaves replicas:
- replication.slaveReplicas: 1
+ replication.slaveReplicas: 2- Set synchronous commit mode:
- replication.synchronousCommit: "off"
+ replication.synchronousCommit: "on"- Number of replicas that will have synchronous replication:
- replication.numSynchronousReplicas: 0
+ replication.numSynchronousReplicas: 1- Start a prometheus exporter:
- metrics.enabled: false
+ metrics.enabled: trueTo horizontally scale this chart, you can use the --replicas flag to modify the number of nodes in your PostgreSQL deployment. Also you can use the values-production.yaml file or modify the parameters shown above.
At the top level, there is a service object which defines the services for both master and slave. For deeper customization, there are service objects for both the master and slave types individually. This allows you to override the values in the top level service object so that the master and slave can be of different service types and with different clusterIPs / nodePorts. Also in the case you want the master and slave to be of type nodePort, you will need to set the nodePorts to different values to prevent a collision. The values that are deeper in the master.service or slave.service objects will take precedence over the top level service object.
To modify the PostgreSQL version used in this chart you can specify a valid image tag using the image.tag parameter. For example, image.tag=12.0.0
This helm chart also supports to customize the whole configuration file.
Add your custom file to "files/postgresql.conf" in your working directory. This file will be mounted as configMap to the containers and it will be used for configuring the PostgreSQL server.
Alternatively, you can specify PostgreSQL configuration parameters using the postgresqlConfiguration parameter as a dict, using camelCase, e.g. {"sharedBuffers": "500MB"}.
In addition to these options, you can also set an external ConfigMap with all the configuration files. This is done by setting the configurationConfigMap parameter. Note that this will override the two previous options.
If you don't want to provide the whole PostgreSQL configuration file and only specify certain parameters, you can add your extended .conf files to "files/conf.d/" in your working directory.
Those files will be mounted as configMap to the containers adding/overwriting the default configuration using the include_dir directive that allows settings to be loaded from files other than the default postgresql.conf.
Alternatively, you can also set an external ConfigMap with all the extra configuration files. This is done by setting the extendedConfConfigMap parameter. Note that this will override the previous option.
The Bitnami PostgreSQL image allows you to use your custom scripts to initialize a fresh instance. In order to execute the scripts, they must be located inside the chart folder files/docker-entrypoint-initdb.d so they can be consumed as a ConfigMap.
Alternatively, you can specify custom scripts using the initdbScripts parameter as dict.
In addition to these options, you can also set an external ConfigMap with all the initialization scripts. This is done by setting the initdbScriptsConfigMap parameter. Note that this will override the two previous options. If your initialization scripts contain sensitive information such as credentials or passwords, you can use the initdbScriptsSecret parameter.
The allowed extensions are .sh, .sql and .sql.gz.
If you need additional containers to run within the same pod as PostgreSQL (e.g. an additional metrics or logging exporter), you can do so via the sidecars config parameter. Simply define your container according to the Kubernetes container spec.
# For the PostgreSQL master
master:
sidecars:
- name: your-image-name
image: your-image
imagePullPolicy: Always
ports:
- name: portname
containerPort: 1234
# For the PostgreSQL replicas
slave:
sidecars:
- name: your-image-name
image: your-image
imagePullPolicy: Always
ports:
- name: portname
containerPort: 1234The chart optionally can start a metrics exporter for prometheus. The metrics endpoint (port 9187) is not exposed and it is expected that the metrics are collected from inside the k8s cluster using something similar as the described in the example Prometheus scrape configuration.
The exporter allows to create custom metrics from additional SQL queries. See the Chart's values.yaml for an example and consult the exporters documentation for more details.
In more complex scenarios, we may have the following tree of dependencies
+--------------+
| |
+------------+ Chart 1 +-----------+
| | | |
| --------+------+ |
| | |
| | |
| | |
| | |
v v v
+-------+------+ +--------+------+ +--------+------+
| | | | | |
| PostgreSQL | | Sub-chart 1 | | Sub-chart 2 |
| | | | | |
+--------------+ +---------------+ +---------------+
The three charts below depend on the parent chart Chart 1. However, subcharts 1 and 2 may need to connect to PostgreSQL as well. In order to do so, subcharts 1 and 2 need to know the PostgreSQL credentials, so one option for deploying could be deploy Chart 1 with the following parameters:
postgresql.postgresqlPassword=testtest
subchart1.postgresql.postgresqlPassword=testtest
subchart2.postgresql.postgresqlPassword=testtest
postgresql.postgresqlDatabase=db1
subchart1.postgresql.postgresqlDatabase=db1
subchart2.postgresql.postgresqlDatabase=db1
If the number of dependent sub-charts increases, installing the chart with parameters can become increasingly difficult. An alternative would be to set the credentials using global variables as follows:
global.postgresql.postgresqlPassword=testtest
global.postgresql.postgresqlDatabase=db1
This way, the credentials will be available in all of the subcharts.
The Bitnami PostgreSQL image stores the PostgreSQL data and configurations at the /bitnami/postgresql path of the container.
Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. See the Parameters section to configure the PVC or to disable persistence.
If you already have data in it, you will fail to sync to standby nodes for all commits, details can refer to code. If you need to use those data, please covert them to sql and import after helm install finished.
To enable network policy for PostgreSQL, install a networking plugin that implements the Kubernetes NetworkPolicy spec, and set networkPolicy.enabled to true.
For Kubernetes v1.5 & v1.6, you must also turn on NetworkPolicy by setting the DefaultDeny namespace annotation. Note: this will enforce policy for all pods in the namespace:
$ kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}"With NetworkPolicy enabled, traffic will be limited to just port 5432.
For more precise policy, set networkPolicy.allowExternal=false. This will only allow pods with the generated client label to connect to PostgreSQL.
This label will be displayed in the output of a successful install.
Differences between Bitnami PostgreSQL image and Docker Official image
- The Docker Official PostgreSQL image does not support replication. If you pass any replication environment variable, this would be ignored. The only environment variables supported by the Docker Official image are POSTGRES_USER, POSTGRES_DB, POSTGRES_PASSWORD, POSTGRES_INITDB_ARGS, POSTGRES_INITDB_WALDIR and PGDATA. All the remaining environment variables are specific to the Bitnami PostgreSQL image.
- The Bitnami PostgreSQL image is non-root by default. This requires that you run the pod with
securityContextand updates the permissions of the volume with aninitContainer. A key benefit of this configuration is that the pod follows security best practices and is prepared to run on Kubernetes distributions with hard security constraints like OpenShift. - For OpenShift, one may either define the runAsUser and fsGroup accordingly, or try this more dynamic option: volumePermissions.securityContext.runAsUser="auto",securityContext.enabled=false,shmVolume.chmod.enabled=false
From chart version 4.0.0, it is possible to use this chart with the Docker Official PostgreSQL image. Besides specifying the new Docker repository and tag, it is important to modify the PostgreSQL data directory and volume mount point. Basically, the PostgreSQL data dir cannot be the mount point directly, it has to be a subdirectory.
image.repository=postgres
image.tag=10.6
postgresqlDataDir=/data/pgdata
persistence.mountPath=/data/
It's necessary to specify the existing passwords while performing an upgrade to ensure the secrets are not updated with invalid randomly generated passwords. Remember to specify the existing values of the postgresqlPassword and replication.password parameters when upgrading the chart:
$ helm upgrade my-release stable/postgresql \
--set postgresqlPassword=[POSTGRESQL_PASSWORD] \
--set replication.password=[REPLICATION_PASSWORD]Note: you need to substitute the placeholders [POSTGRESQL_PASSWORD], and [REPLICATION_PASSWORD] with the values obtained from instructions in the installation notes.
Prefixes the port names with their protocols to comply with Istio conventions.
If you depend on the port names in your setup, make sure to update them to reflect this change.
Adds support for LDAP configuration.
Helm performs a lookup for the object based on its group (apps), version (v1), and kind (Deployment). Also known as its GroupVersionKind, or GVK. Changing the GVK is considered a compatibility breaker from Kubernetes' point of view, so you cannot "upgrade" those objects to the new GVK in-place. Earlier versions of Helm 3 did not perform the lookup correctly which has since been fixed to match the spec.
In helm/charts#17281 the apiVersion of the statefulset resources was updated to apps/v1 in tune with the api's deprecated, resulting in compatibility breakage.
This major version bump signifies this change.
In this version, the chart will use PostgreSQL with the Postgis extension included. The version used with Postgresql version 10, 11 and 12 is Postgis 2.5. It has been compiled with the following dependencies:
- protobuf
- protobuf-c
- json-c
- geos
- proj
In this version, the chart is using PostgreSQL 11 instead of PostgreSQL 10. You can find the main difference and notable changes in the following links: https://www.postgresql.org/about/news/1894/ and https://www.postgresql.org/about/featurematrix/.
For major releases of PostgreSQL, the internal data storage format is subject to change, thus complicating upgrades, you can see some errors like the following one in the logs:

[1] FATAL: database files are incompatible with server
[1] DETAIL: The data directory was initialized by PostgreSQL version 10, which is not compatible with this version 11.3.In this case, you should migrate the data from the old chart to the new one following an approach similar to that described in this section from the official documentation. Basically, create a database dump in the old chart, move and restore it in the new one.
This chart will use by default the Bitnami PostgreSQL container starting from version 10.7.0-r68. This version moves the initialization logic from node.js to bash. This new version of the chart requires setting the POSTGRES_PASSWORD in the slaves as well, in order to properly configure the pg_hba.conf file. Users from previous versions of the chart are advised to upgrade immediately.
IMPORTANT: If you do not want to upgrade the chart version then make sure you use the 10.7.0-r68 version of the container. Otherwise, you will get this error
The POSTGRESQL_PASSWORD environment variable is empty or not set. Set the environment variable ALLOW_EMPTY_PASSWORD=yes to allow the container to be started with blank passwords. This is recommended only for development
This releases make it possible to specify different nodeSelector, affinity and tolerations for master and slave pods.
It also fixes an issue with postgresql.master.fullname helper template not obeying fullnameOverride.
affintyhas been renamed tomaster.affinityandslave.affinity.tolerationshas been renamed tomaster.tolerationsandslave.tolerations.nodeSelectorhas been renamed tomaster.nodeSelectorandslave.nodeSelector.
In order to upgrade from the 0.X.X branch to 1.X.X, you should follow the below steps:
- Obtain the service name (
SERVICE_NAME) and password (OLD_PASSWORD) of the existing postgresql chart. You can find the instructions to obtain the password in the NOTES.txt, the service name can be obtained by running
$ kubectl get svc- Install (not upgrade) the new version
$ helm repo update
$ helm install my-release bitnami/postgresql- Connect to the new pod (you can obtain the name by running
kubectl get pods):
$ kubectl exec -it NAME bash- Once logged in, create a dump file from the previous database using
pg_dump, for that we should connect to the previous postgresql chart:
$ pg_dump -h SERVICE_NAME -U postgres DATABASE_NAME > /tmp/backup.sqlAfter run above command you should be prompted for a password, this password is the previous chart password (OLD_PASSWORD).
This operation could take some time depending on the database size.
- Once you have the backup file, you can restore it with a command like the one below:
$ psql -U postgres DATABASE_NAME < /tmp/backup.sqlIn this case, you are accessing to the local postgresql, so the password should be the new one (you can find it in NOTES.txt).
If you want to restore the database and the database schema does not exist, it is necessary to first follow the steps described below.
$ psql -U postgres
postgres=# drop database DATABASE_NAME;
postgres=# create database DATABASE_NAME;
