The crunchy-collect container can be placed within a database pod to begin the collection of 30+ PostgreSQL metrics. 3 High Availability with Crunchy-watch. Provisioning the new replica can take some time depending on how large your data set is. A fully managed cloud Postgres service that allows you to focus on your application, not your database. Get started with Crunchy Bridge by creating your account and provision your production ready database on the cloud of your choice. Fortunately, the Crunchy PostgreSQL Operator is prepared for this. Destroys the current primary PostgreSQL instance to prevent the "split-brain" problem from occurring. These advanced features were provided to allow enterprise customers the ability to perform basic administration tasks common to running a PostgreSQL database or cluster. This way, the clients will find the new master using the existing master service as before. . In this follow up several new advanced features are highlighted from the Crunchy PostgreSQL for Kubernetes. Tutorials Katacoda Learning Portal. Read up on the capabilities provided by Crunchy Bridge, including supported extensions, pricing, and features. Learn PostgreSQL by example with interactive courses designed by our experts. We all know how easy is setting up an Amazon RDS-based PostgreSQL cluster with automatic failover that just works out of the box. Some containers are in development and not open sourced at this time, they include: In the following sections we will discuss some of these container features. First, you should determine which of your replicas are available to fail over to. ... and make sure to avoid overwriting any existing data storage. The PostgreSQL Operator uses the open source Patroni high-availability framework and the open source disaster recovery management tool pgBackRest to enable this functionality. Crunchy PostgreSQL for Kubernetes includes the Crunchy PostgreSQL Operator, which provides a simple interface to provision, secure, and elastically scale database clusters in your Kubernetes environment. An example of restoring from a database archive is found here. If not, crunchy-watch will create a trigger file on the first slave it finds. Promotes the selected replica to begin accepting write queries. Deletion of the master pod will initiate a failover. Get started with Crunchy Bridge by creating your account and provision your production ready database on the cloud of your choice. In this follow up several new advanced features are highlighted from the, - runs PostgreSQL and also performs a backup restore, - performs a pg_basebackup on a database container, - hosts a simple http server that executes pgbadger against a database container to produce HTML reports that provide detailed PostgreSQL log analysis, - provides a pgpool container that lets applications access a PostgreSQL cluster via a single connection, - collects 32 different PostgreSQL metrics from a database container and pushed them to a Prometheus time series data store, - provides a web based graphing dashboard for collected PostgreSQL metrics, - provides a prometheus datastore for metrics collection, - provides a simple form of automated failover as well as basic pg_bouncer connection pooling, - provides a form of automated failover by watching a PostgreSQL cluster’s master and triggers a failover on a slave if the master is not responding, - provides a cron scheduler for executing vacuum and backup jobs, - provides a microservice for running PostgreSQL vacuum commands. One means of causing this failover is to create a predefined trigger file on the slave, after which, the PostgreSQL server will alter its configuration to become a read-write master database. When failing over from a primary database to a replica database, there are a few things you should keep in mind: The PostgreSQL Operator helps to simplify the failover process with the "failover" command which, after you select a replica, does the following behind the scenes: The process of destroying the old primary and promoting the new primary takes only a matter of seconds.
