You will then see a high-availability cluster start up. To get started, do the following from different terminals: > etcd -data-dir=data/etcd -enable-v2=true WAL-E) should be installed independently of Patroni. Note that external tools to call in the replica creation or custom bootstrap scripts (i.e.

Where dependencies can be either empty, or consist of one or more of the following: etcd or etcd3 python-etcd module in order to use Etcd as DCS consul python-consul module in order to use Consul as DCS zookeeper kazoo module in order to use Zookeeper as DCS exhibitor kazoo module in order to use Exhibitor as DCS (same dependencies as for Zookeeper) kubernetes kubernetes module in order to use Kubernetes as DCS in Patroni raft pysyncobj module in order to use python Raft implementation as DCS aws boto3 in order to use AWS callbacksįor example, the command in order to install Patroni together with dependencies for Etcd as a DCS and AWS callbacks is: pip install patroni Patroni can be installed with pip: pip install patroni Install psycopg2 from the binary package.Sudo yum install python-psycopg2 # install python2 psycopg2 on RedHat/Fedora/CentOS Sudo apt-get install python3-psycopg2 # install python3 psycopg2 module on Debian/Ubuntu
Sudo apt-get install python-psycopg2 # install python2 psycopg2 module on Debian/Ubuntu
#POSTGRESQL GIT REPOSITORY HOW TO#
Since in the python world it is not possible to specify dependency as psycopg2 OR psycopg2-binary you will have to decide how to install it.
#POSTGRESQL GIT REPOSITORY CODE#
Installing it from the source code requires C compiler and postgres+python dev packages. Starting from psycopg2-2.8 the binary version of psycopg2 will no longer be installed by default. To install requirements on a Mac, run the following: brew install postgresql etcd haproxy libyaml python If you're using Patroni, or just interested, please join us. There are two places to connect with the Patroni community: on github, via Issues and PRs, and on channel #patroni in the PostgreSQL Slack. See our Contributing section below for more details. Patroni is in active development and accepts contributions. PostgreSQL HA with Kubernetes and Patroni, talk by Josh Berkus at KubeCon 2016 (video).Elephants on Automatic: HA Clustered PostgreSQL with Helm, talk by Josh Berkus and Oleksii Kliukin at KubeCon Berlin 2017.It includes plenty of new features.įor an example of a Docker-based deployment with Patroni, see Spilo, currently in use at Zalando. Patroni originated as a fork of Governor, the project from Compose. Take a look at the Kubernetes chapter of the Patroni documentation. Note to Kubernetes users: Patroni can run natively on top of Kubernetes. Please check the Citus support page in the Patroni documentation for more info about how to use Patroni high availability together with a Citus distributed cluster.
Note to Citus users: Starting from 3.0 Patroni nicely integrates with the Citus database extension to Postgres. Use wisely.Ĭurrently supported PostgreSQL versions: 9.3 to 15. We call Patroni a "template" because it is far from being a one-size-fits-all or plug-and-play replication system. Database engineers, DBAs, DevOps engineers, and SREs who are looking to quickly deploy HA PostgreSQL in datacenters - or anywhere else - will hopefully find it useful. For maximum accessibility, Patroni supports a variety of distributed configuration stores like ZooKeeper, etcd, Consul or Kubernetes. Patroni is a template for high availability (HA) PostgreSQL solutions using Python. There are many ways to run high availability with PostgreSQL for a list, see the PostgreSQL Documentation. You can find a version of this documentation that is searchable and also easier to navigate at. Patroni: A Template for PostgreSQL HA with ZooKeeper, etcd or Consul Replication slots are copied from primary to standbys. Physical permanent slots are maintained only in the primary, while logical Through this commit we also enhance the docs in terms of explaining that Out Patroni will make the slot permanent in the primary even if the member If you specify a slot name thatĬlashes with the name of a replication slot used by a member, it turns However that is not true in the sense that Patroni does not check forĬlashes between `my_slot_name` and the name of replication slots createdįor replicating changes among members. There are no clashes in names between replication slots automaticallyĬreated by Patroni for members and permanent replication slots.
