# PostgreSQL HA
|
||||
|
||||
This Helm chart has been developed based on [stable/postgresql](https://github.com/helm/charts/tree/master/stable/postgresql) chart but including some changes to guarantee high availability such as:
|
||||
|
||||
- A new deployment, service and ingress have been added to deploy [Pgpool-II](Pgpool-II) to act as proxy for PostgreSQL backend. It helps to reduce connection overhead, acts as a load balancer for PostgreSQL, and ensures database node failover.
|
||||
- Replacing `bitnami/postgresql` with `bitnami/postgresql-repmgr` which includes and configures [repmgr](https://repmgr.org/). Repmgr ensures standby nodes assume the primary role when the primary node is unhealthy.
|
||||
|
||||
## TL;DR:
|
||||
|
||||
```
|
||||
$ helm repo add bitnami https://charts.bitnami.com/bitnami
|
||||
$ helm install bitnami/postgresql-ha
|
||||
```
|
||||
|
||||
## Introduction
|
||||
|
||||
This [Helm](https://github.com/kubernetes/helm) chart installs [PostgreSQL](https://www.postgresql.org/) with HA architecture in a Kubernetes cluster. Welcome to [contribute](CONTRIBUTING.md) to Helm Chart for PostgreSQL HA.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes cluster 1.10+
|
||||
- Helm 2.8.0+
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
Install the PostgreSQL HA helm chart with a release name `my-release`:
|
||||
|
||||
```bash
|
||||
$ helm repo add bitnami https://charts.bitnami.com/bitnami
|
||||
$ helm install --name my-release bitnami/postgresql-ha
|
||||
```
|
||||
|
||||
## Uninstalling the Chart
|
||||
|
||||
To uninstall/delete the `my-release` deployment:
|
||||
|
||||
```bash
|
||||
$ helm delete --purge my-release
|
||||
```
|
||||
|
||||
Additionaly, if `persistence.resourcePolicy` is set to `keep`, you should manually delete the PVCs.
|
||||
|
||||
## Downloading the chart
|
||||
|
||||
Download PostgreSQL HA helm chart
|
||||
|
||||
```bash
|
||||
$ git clone https://github.com/bitnami/charts
|
||||
```
|
||||
|
||||
Change directory to PostgreSQL code
|
||||
|
||||
```bash
|
||||
$ cd charts/bitnami/postgresql-ha
|
||||
```
|
||||
|
||||

||||
| `ingress.hosts[0].name` | Hostname for PostgreSQL service | `postgresql.local` |
|
||||
| `ingress.hosts[0].path` | Path within the url structure | `/` |
|
||||
| `ingress.tls[0].hosts[0]` | TLS hosts | `postgresql.local` |

|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release \
|
||||
--set postgresql.password=password \
|
||||
bitnami/postgresql-ha
|
||||
```
|
||||
|
||||
The above command sets the password for user `postgres` to `password`.
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release -f values.yaml bitnami/postgresql-ha
|
||||
```
|
||||
|
||||
### Change PostgreSQL version
|
||||
|
||||
To modify the PostgreSQL version used in this chart you can specify a [valid image tag](https://hub.docker.com/r/bitnami/postgresql/tags/) using the `--set image.tag` argument to `helm install`. For example,
|
||||
|
||||
```console
|
||||
$ helm install --name my-release --set image.tag=9.6.15-centos-7-r9 bitnami/postgresql-ha
|
||||
```
|
||||
|
||||
### Horizontal scaling
|
||||
|
||||
To horizontally scale this chart once it has been deployed:
|
||||
|
||||
```console
|
||||
$ helm upgrade my-release bitnami/postgresql-ha \
|
||||
--set postgresql.password=[POSTGRESQL_PASSWORD] \
|
||||
--set postgresql.repmgrPassword=[REPMGR_PASSWORD] \
|
||||
--set postgresql.replicaCount=5
|
||||
```
|
||||
|
||||
> Note: Scaling the statefulset with `kubectl scale ...` command is highly discouraged. Use `helm upgrade ...` for horizontal scaling so you ensure all the environment variables used to configure the PostgreSQL HA cluster are properly updated.
|
||||
|
||||
> Note: you need to substitute the placeholders _[POSTGRESQL_PASSWORD]_, and _[REPMGR_PASSWORD]_ with the values obtained from instructions in the installation notes.
|
||||
|
||||
### Configure the way how to expose PostgreSQL
|
||||
|
||||
- **Ingress**: The ingress controller must be installed in the Kubernetes cluster. Set `ingress.enabled=true` to expose PostgreSQL through Ingress.
|
||||
- **ClusterIP**: Exposes the service on a cluster-internal IP. Choosing this value makes the service only reachable from within the cluster. Set `service.type=ClusterIP` to choose this service type.
|
||||
- **NodePort**: Exposes the service on each Node's IP at a static port (the NodePort). You’ll be able to contact the NodePort service, from outside the cluster, by requesting `NodeIP:NodePort`. Set `service.type=NodePort` to choose this service type.
|
||||
- **LoadBalancer**: Exposes the service externally using a cloud provider's load balancer. Set `service.type=LoadBalancer` to choose this service type.
|
||||
|
||||
### Adjust permissions of persistent volume mountpoint
|
||||
|
||||
As the images run as non-root by default, it is necessary to adjust the ownership of the persistent volumes so that the containers can write data into it.
|
||||
|
||||
By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
|
||||
As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.
|
||||
|
||||
You can enable this initContainer by setting `volumePermissions.enabled` to `true`.
|
||||
|
||||
### LDAP
|
||||
|
||||
LDAP support can be enabled in the chart by specifying the `ldap.` parameters while creating a release. The following parameters should be configured to properly enable the LDAP support in the chart.
|
||||
|
||||
- **ldap.enabled**: Enable LDAP support. Defaults to `false`.
|
||||
- **ldap.uri**: LDAP URL beginning in the form `ldap[s]://<hostname>:<port>`. No defaults.
|
||||
- **ldap.base**: LDAP base DN. No defaults.
|
||||
- **ldap.binddn**: LDAP bind DN. No defaults.
|
||||
- **ldap.bindpw**: LDAP bind password. No defaults.
|
||||
- **ldap.bslookup**: LDAP base lookup. No defaults.
|
||||
- **ldap.nss_initgroups_ignoreusers**: LDAP ignored users. `root,nslcd`.
|
||||
- **ldap.scope**: LDAP search scope. No defaults.
|
||||
- **ldap.tls_reqcert**: LDAP TLS check on server certificates. No defaults.
|
||||
|
||||
For example:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release bitnami/postgresql-ha \
|
||||
--set ldap.enabled="true" \
|
||||
--set ldap.uri="ldap://my_ldap_server" \
|
||||
--set ldap.base="dc=example\,dc=org" \
|
||||
--set ldap.binddn="cn=admin\,dc=example\,dc=org" \
|
||||
--set ldap.bindpw="admin" \
|
||||
--set ldap.bslookup="ou=group-ok\,dc=example\,dc=org" \
|
||||
--set ldap.nss_initgroups_ignoreusers="root\,nslcd" \
|
||||
--set ldap.scope="sub" \
|
||||
--set ldap.tls_reqcert="demand"
|
||||
```

|
||||
### Production configuration
|
||||
|
||||
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`:
|
||||
|
||||
- Enable Newtworkpolicy blocking external access:
|
||||
|
||||
```diff
|
||||
- networkPolicy.enabled: false
|
||||
+ networkPolicy.enabled: true
|
||||
- networkPolicy.allowExternal: true
|
||||
+ networkPolicy.allowExternal: false
|
||||
```
|
||||
|
||||
- Start a side-car prometheus exporter:
|
||||
|
||||
```diff
|
||||
- metrics.enabled: false
|
||||
+ metrics.enabled: true
|
||||
```
|
||||
|
||||
### [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.
|
||||
|
||||
### repmgr.conf / postgresql.conf / pg_hba.conf files as configMap
|
||||
|
||||
This helm chart also supports to customize the whole configuration file.
|
||||
|
||||
Add your custom files to "files" in your working directory. Those files will be mounted as configMap to the containers and it will be used for configuring Repmgr and the PostgreSQL server.
|
||||
|
||||
Alternatively, you can specify the PostgreSQL and Repmgr configuration using the `postgresql.configuration`, `postgresql.pgHbaConfiguration`, and `postgresql.repmgrConfiguration` parameters.
|
||||
|
||||
In addition to these options, you can also set an external ConfigMap with all the configuration files. This is done by setting the `postgresql.configurationCM` parameter. Note that this will override the two previous options.
|
||||
|
||||
### Allow settings to be loaded from files other than the default `postgresql.conf`
|
||||
|
||||
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 specify the extended configuration using the `postgresql.extendedConf` parameter.
|
||||
|
||||
In addition to these options, you can also set an external ConfigMap with all the extra configuration files. This is done by setting the `postgresql.extendedConfCM` parameter. Note that this will override the two previous options.
|
||||
|
||||
## Initialize a fresh instance
|
||||
|
||||
The [Bitnami PostgreSQL with Repmgr](https://github.com/bitnami/bitnami-docker-postgresql-repmgr) 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 `postgresql.initdbScriptsCM` 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`.
|
||||
|
||||
## Persistence
|
||||
|
||||
The data is persisted by default using PVC templates in the PostgreSQL statefulset. You can disable the persistence setting the `persistence.enabled` parameter to `false`.
|
||||
A default `StorageClass` is needed in the Kubernetes cluster to dynamically provision the volumes. Specify another StorageClass in the `persistence.storageClass` or set `persistence.existingClaim` if you have already existing persistent volumes to use.
|
||||
|
||||
## Use of global variables
|
||||
|
||||
In more complex scenarios, we may have the following tree of dependencies
|
||||
|
||||
```
|
||||
+--------------+
|
||||
| |
|
||||
+------------+ Chart 1 +-----------+
|
||||
| | | |
|
||||
| --------+------+ |
|
||||
| | |
|
||||
| | |
|
||||
| | |
|
||||
| | |
|
||||
v v v
|
||||
+-------+------+ +--------+------+ +--------+------+
|
||||
| | | | | |
|
||||
|PostgreSQL HA | | 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 HA as well. In order to do so, subcharts 1 and 2 need to know the PostgreSQL HA credentials, so one option for deploying could be:
|
||||
|
||||
```bash
|
||||
$ helm install chart1 --set postgresql.password=testtest --set subchart1.postgresql.password=testtest --set subchart2.postgresql.password=testtest --set postgresql.database=db1 --set subchart1.postgresql.database=db1 --set subchart1.postgresql.database=db1
|
||||
```
|
||||
|
||||
If the number of dependent sub-charts increases, executing `helm install` can become increasingly difficult. An alternative would be to set the credentials using global variables as follows:
|
||||
|
||||
```bash
|
||||
$ helm install chart1 --set global.postgresql.password=testtest --set global.postgresql.database=db1
|
||||
```
|
||||
|
||||
This way, the credentials will be available in all of the subcharts.
|
||||
|
||||
## Upgrade
|
||||
|
||||
It's necessary to specify the existing passwords while performing a upgrade to ensure the secrets are not updated with invalid randomly generated passwords. Remember to specify the existing values of the `postgresql.password` and `postgresql.repmgrPassword` parameters when upgrading the chart:
|
||||
|
||||
```bash
|
||||
$ helm upgrade my-release bitnami/postgresql-ha \
|
||||
--set postgresql.password=[POSTGRESQL_PASSWORD] \
|
||||
--set postgresql.repmgrPassword=[REPMGR_PASSWORD]
|
||||
```
|
||||
|
||||
> Note: you need to substitute the placeholders _[POSTGRESQL_PASSWORD]_, and _[REPMGR_PASSWORD]_ with the values obtained from instructions in the installation notes.
|
||||
|
||||
## 0.4.0
|
||||
|
||||
In this version, the chart will use PostgreSQL-Repmgr container images with the Postgis extension included. The version used in Postgresql version 10, 11 and 12 is Postgis 2.5, and in Pôstgresql 9.6 is Postgis 2.3.
|
||||
Postgis has been compiled with the following dependencies:
|
||||
|
||||
- protobuf
|
||||
- protobuf-c
|

- json-c
|

PostgreSQL can be accessed through Pgpool via port {{ .Values.service.port }} on the following DNS name from within your cluster:
|
||||
|
||||
{{ include "postgresql-ha.pgpool" . }}.{{ .Release.Namespace }}.svc.cluster.local
|
||||
|
||||
Pgpool acts as a load balancer for PostgreSQL and forward read/write connections to the primary node while read-only connections are forwarded to standby nodes.
|
||||
|
||||
To get the password for {{ (include "postgresql-ha.postgresqlUsername" .) | quote }} run:
|
||||
|

## Ingress paramaters
|
||||
##
|
||||
ingress:
|
||||
## Set to true to enable ingress record generation
|
||||
enabled: false
|
||||
|
||||
## Set this to true in order to add the corresponding annotations for cert-manager
|
||||
certManager: false
|
||||
|
||||
## Ingress annotations done as key:value pairs
|
||||
## For a full list of possible ingress annotations, please see
|
||||
## ref: https://github.com/kubernetes/ingress-nginx/blob/master/docs/annotations.md
|
||||
##
|
||||
## If tls is set to true, annotation ingress.kubernetes.io/secure-backends: "true" will automatically be set
|
||||
## If certManager is set to true, annotation kubernetes.io/tls-acme: "true" will automatically be set
|
||||
annotations:
|
||||
# kubernetes.io/ingress.class: nginx
|
||||
|
||||
## The list of hostnames to be covered with this ingress record.
|
||||
## Most likely this will be just one host, but in the event more hosts are needed, this is an array
|
||||
hosts:
|
||||
- name: postgresql.local
|
||||
path: /
|
||||
|
||||
## The tls configuration for the ingress
|
||||
## see: https://kubernetes.io/docs/concepts/services-networking/ingress/#tls
|
||||
tls:
|
||||
- hosts:
|
||||
- postgresql.local
|
||||
secretName: postgresql.local-tls
|
||||
|
||||
secrets:
|
||||
## If you're providing your own certificates, please use this to add the certificates as secrets
|
||||
## key and certificate should start with -----BEGIN CERTIFICATE----- or
|
||||
## -----BEGIN RSA PRIVATE KEY-----
|
||||
##
|
||||
## name should line up with a tlsSecret set further up
|
||||
## If you're using cert-manager, this is unneeded, as it will create the secret for you if it is not set
|
||||
##
|
||||
## It is also possible to create and manage the certificates outside of this helm chart
|
||||
## Please see README.md for more information

|
||||
## The Policy model to apply. When set to false, only pods with the correct
|
||||
## client labels will have network access to the port PostgreSQL is listening
|

## on. When true, PostgreSQL will accept connections from any source
|
||||
## (with the correct destination port).
