Please use [releases][github-release] instead of the `master` branch in order to get stable binaries.  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][raft] consensus algorithm to manage a highly-available replicated log. etcd is used [in production by many companies](./Documentation/production-users.md), and the development team stands behind it in critical deployment scenarios, where etcd is frequently teamed with applications such as [Kubernetes][k8s], [locksmith][locksmith], [vulcand][vulcand], [Doorman][doorman], and many others. Reliability is further ensured by [**rigorous testing**](https://github.com/etcd-io/etcd/tree/master/functional). See [etcdctl][etcdctl] for a simple command line client.

An initial agenda will be posted to the [shared Google docs][shared-meeting-notes] a day before each meeting, and everyone is welcome to suggest additional topics or other agendas.

For more installation guides, please check out [play.etcd.io](http://play.etcd.io) and [operating etcd](https://github.com/etcd-io/etcd/tree/master/Documentation#operating-etcd-clusters). For those wanting to try the very latest version, [build the latest version of etcd][dl-build] from the `master` branch. This first needs [*Go*](https://golang.org/) installed (version 1.12+ is required). All development occurs on `master`, including new features and bug fixes. Bug fixes are first targeted at `master` and subsequently ported to release branches, as described in the [branch management][branch-management] guide. [github-release]: https://github.com/etcd-io/etcd/releases [branch-management]: ./Documentation/branch_management.md [dl-build]: ./Documentation/dl_build.md#build-the-latest-version ### Running etcd First start a single-member cluster of etcd. If etcd is installed using the [pre-built release binaries][github-release], run it from the installation location as below: ```bash /tmp/etcd-download-test/etcd ``` The etcd command can be simply run as such if it is moved to the system path as below: ```bash mv /tmp/etcd-download-test/etcd /usr/local/bin/ etcd ``` If etcd is [built from the master branch][dl-build], run it as below: ```bash ./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: - [Interactive etcd playground](http://play.etcd.io) - [Animated quick demo](./Documentation/demo.md) ### etcd TCP ports The [official etcd ports][iana-ports] are 2379 for client requests, and 2380 for peer communication. [iana-ports]: http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt ### Running a local etcd cluster First install [goreman](https://github.com/mattn/goreman), which manages Procfile-based applications. Our [Procfile script](./Procfile) will set up a local example cluster. Start it with: ```bash goreman start ``` This will bring up 3 etcd members `infra1`, `infra2` and `infra3` and etcd `grpc-proxy`, which runs locally and composes a cluster. Every cluster member and proxy accepts key value reads and key value writes. ### Next steps Now it's time to dig into the full etcd API and other guides. - Read the full [documentation][fulldoc]. - Explore the full gRPC [API][api]. - Set up a [multi-machine cluster][clustering]. - Learn the [config format, env variables and flags][configuration]. - Find [language bindings and tools][integrations]. - Use TLS to [secure an etcd cluster][security]. - [Tune etcd][tuning].

In that case, please reach out to the project [MAINTAINERS](https://github.com/etcd-io/etcd/blob/master/OWNERS) to first discuss the vulnerabilities with them and take necessary action per such discussion. ## Issue and PR management See [issue triage guidelines](Documentation/triage/issues.md) for details on how issues are managed.
