Getting Started

Download and Start Temporal Server Locally

Execute the following commands to start a pre-built image along with all the dependencies.

git clone
cd docker-compose
docker-compose up

Refer to Temporal docker-compose repo for more advanced options.

Run the Samples

Clone or download samples for Go or Java and run them with the local Temporal server. We have a number of HelloWorld type scenarios available, as well as more advanced ones. Note that the sets of samples are currently different between Go and Java.


Use Temporal's command line tool tctl to interact with the local Temporal server.

alias tctl="docker exec temporal-admin-tools tctl"
tctl namespace list
tctl workflow list

Use Temporal Web UI

Try Temporal Web UI by opening http://localhost:8088 for viewing your sample workflows executing on Temporal.


This repository contains the source code of the Temporal server. To implement Workflows, Activities and Workers, use Go SDK or Java SDK.
