If you use the Azure Cloud Shell, kubectl is already installed. In order to connect to the Kubernetes cluster from the Visual Studio running on the local computer, we will need to install it. The kubectl its the Kubernetes command-line client. Let's create a resource group using the az-group-create command in the east us region.Īz group create -name $resourceGroup -location $regionĭeploy an AKS cluster to run the pgBouncer sidecar container and PSQL client in order to test the pgBouncer connectivity with the PostgreSQL server.Īz aks create -n $aksClusterName -g $resourceGroup -enable-addons azure-keyvault-secrets-provider -enable-managed-identity -node-count 1 -node-osdisk-type Ephemeral -enable-secret-rotation ![]() Steps to setup PgBouncer on Azure Kubernetes Service (AKS)Īll of the steps below will be executed using Visual Studio Code, Azure CLI, and Kubectl.Īn Azure resource group is a logical group in which Azure resources are deployed and managed. Take a look at the comparison table between Single Server and Flexible Server ![]() However, we encourage you to adopt Flexible Server which has richer capabilities including Pgbouncer built-in. This article describes best practices for those who are still using the Single Server option based on their own requirements. Note: In this article, a PSQL client image will be deployed rather than a sample web application to establish the connection through pgbouncer. The Azure Storage account stores the pgbouncer.ini configuration file that is shareable to multiple containers.In this architecture, de Azure Key Vault will be used to securely store the database credentials. The Azure Key vault provides a security layer for managing and storing the application credentials and connection strings among others.A file named userlist.txt has all PostgreSQL credentials.A file named pgbouncer.ini which has all configurations of the pgbouncer.The pgbouncer image requires two configuration files as following below:.The PGbouncer image it's deployed as a sidecar container on the same pod of the application’s container.The application will connect with the database through pgbouncer connection pooling.The application uses in the database layer the Azure Database for PostgreSQL Single-Server.The proposed architecture consists of the following workflow: AKS has been chosen for didactic purposes following the below architecture: Supposing that you have a containerized application and looking forward to having PGbouncer implemented no matter it's running on Azure Kubernetes Service (AKS), Azure Container Instance (ACI), Azure Container Apps (ACA), or Azure Red Hat OpenShift (ARO) you can setup PGbouncer as Sidecar container at the same pod where your application’s container is wrapped up. However, it is a PaaS offering in which you won’t have access to install any external component on the database server, like a Pgbouncer connection pooling. If you are looking to install and run PgBouncer on Ubuntu VM, you should move on to the last blog post Steps to install and setup PgBouncer connection pooling proxy with Azure DB for PostgreSQL.Īzure Database for PostgreSQL Single Server is a fully managed platform service that provides a lot of database capabilities to support your application in a cloud native design implementation. The blog post is intended to focus on steps for install and setup the PgBouncer as a sidecar pattern enabling connection pooling between a containerized application and Azure DB for PostgreSQL Single-Server. Besides, he showed the performance improvements with a simple benchmark test with pgbench, and shared the steps to install the pgbouncer in a VM. Savjani in the previous blog post explained about the Pgbouncer and the importance of using a connection pooling with Azure Database for PostgreSQL. ![]()
