etcd
Note: The main
branch may be in an unstable or even broken state during development. For stable versions, see releases.
[etcd Logo](logos/etcd-horizontal-color.svg)
etcd is a distributed reliable key-value store for the most critical data of a distributed system, with a focus on being:
- Simple: well-defined, user-facing API (gRPC)
- Secure: automatic TLS with optional client cert authentication
- Fast: benchmarked 10,000 writes/sec
- Reliable: properly distributed using Raft
etcd is written in Go and uses the Raft consensus algorithm to manage a highly-available replicated log.
etcd is used [in production by many companies](./ADOPTERS.md), and the development team stands behind it in critical deployment scenarios, where etcd is frequently teamed with applications such as Kubernetes, locksmith, vulcand, Doorman, and many others. Reliability is further ensured by rigorous testing.
See etcdctl for a simple command line client.
Community meetings
etcd contributors and maintainers have monthly (every four weeks) meetings at 11:00 AM (USA Pacific) on Thursday.
An initial agenda will be posted to the shared Google docs a day before each meeting, and everyone is welcome to suggest additional topics or other agendas.
Meeting recordings are uploaded to Etcd YouTube channel.

Maintainers
[MAINTAINERS](MAINTAINERS) strive to shape an inclusive open source project culture where users are heard and contributors feel respected and empowered. MAINTAINERS maintain productive relationships across different companies and disciplines. Read more about [MAINTAINERS role and responsibilities](GOVERNANCE.md#maintainers).
Getting started
Getting etcd
The easiest way to get etcd is to use one of the pre-built release binaries which are available for OSX, Linux, Windows, and Docker on the release page.
For more installation guides, please check out play.etcd.io and operating etcd.
For those wanting to try the very latest version, build the latest version of etcd from the main
branch. This first needs Go installed (version 1.17+ is required). All development occurs on main
, including new features and bug fixes. Bug fixes are first targeted at main
and subsequently ported to release branches, as described in the branch management guide.
Running etcd
First start a single-member cluster of etcd.
If etcd is installed using the pre-built release binaries, run it from the installation location as below:
/tmp/etcd-download-test/etcd
The etcd command can be simply run as such if it is moved to the system path as below:
mv /tmp/etcd-download-test/etcd /usr/local/bin/
etcd
If etcd is built from the main branch, run it as below:
./bin/etcd
This will bring up etcd listening on port 2379 for client communication and on port 2380 for server-to-server communication.
Next, let's set a single key, and then retrieve it:
etcdctl put mykey "this is awesome"
etcdctl get mykey
etcd is now running and serving client requests. For more, please check out:
etcd TCP ports
The official etcd ports are 2379 for client requests, and 2380 for peer communication.
Running a local etcd cluster
First install goreman, which manages Procfile-based applications.
Our [Procfile script](./Procfile) will set up a local example cluster. Start it with:
goreman start
This will bring up 3 etcd members infra1
, infra2
and infra3
and optionally etcd grpc-proxy
, which runs locally and composes a cluster.
Every cluster member and proxy accepts key value reads and key value writes.
Follow the steps in [Procfile.learner](./Procfile.learner) to add a learner node to the cluster. Start the learner node with:
goreman -f ./Procfile.learner start
Install etcd client v3
go get go.etcd.io/etcd/client/v3
