If you have multiple subscriptions, choose the appropriate subscription in which the resource should be billed. Note the id property from the command output for the corresponding subscription name. Login to your account using the az login command. To see the version installed, run the az -version command. Install Azure CLI.version 2.0 or later locally. If you don't have an Azure subscription, create a free account before you begin. Create a PostgreSQL flexible server in a virtual network.One caveat is that once you fork, you won't be able to use fly postgres commands to administer your app. You can even update an existing cluster with your new image using fly deploy -image. Just fork fly-apps/postgres-ha and add whatever meets your needs. The Fly Postgres app is fully open source. You can also add read-only replicas in other regions and take advantage of the Fly.io platform's proxy features to build a Globally Distributed Postgres cluster. If you have an app that connects to your database, make sure that it also scales to zero (otherwise the connection remaining open will prevent it from "going to sleep"). It's not magic: it's just how our apps work. In the single-instance "Development" config, you'll aslo be given the option to activate "automatic scale to zero". Fly Postgres is designed so that you can turn a single-node cluster into a high-availability one just by adding a second instance in the same region. In the latter case, you will lose any data accumulated since the last snapshot. If you choose this option and the hardware it's running on has network problems or the SSD fails, your database will go down. In case of a node failure, a HA Fly Postgres cluster will automatically take the bad actor out of the picture and, if necessary, fail over leadership to the healthy node.įlyctl also offers a single-instance "Development" config. The "High Availability" options are three-node clusters. When you create a Fly Postgres cluster, you're offered several preset configurations. Read about why Fly Postgres is not the same thing as a managed database service. It comes with most commonly used functionality (replication, failover, metrics, monitoring and daily snapshots). Postgres, formally known as PostgreSQL, is a powerful open source object relational database system that's used by many popular web frameworks to persist application data.įly Postgres is a Fly app with flyctl sugar on top to help you bootstrap and manage a database cluster for your apps. ![]() Docs for these databases can be found here: Existing Fly Postgres clusters will continue to work, powered by Nomad. Fly Postgres clusters created with flyctl v0.0.412 or newer use our next-gen Apps V2 architecture, built on Fly Machines. ![]()
