This repository provides Kubernetes manifests that enable you to run a development version of the Temporal Server. There are a variety of manifest folders, each setup to utilize a different set of dependencies.
To use these manifests, you must first have a Kubernetes cluster setup. If you'd just like to try this locally without using a Kubernetes cluster setup in the cloud then tools like minikube, kind or Docker Desktop's built-in kubernetes setup will all work just fine to create a cluster you can use for exploring Temporal.
You must have kubectl configured and be able to succesfully run commands like kubectl get pods to be able to follow the examples in this document.
The following command will run a developer setup of the Temporal Server and its default dependencies in the temporal namespace in your Kubernetes cluster:
kubectl create namespace temporal
kubectl apply -n temporal -R -f https://raw.githubusercontent.com/temporalio/docker-compose/main/k8s/temporal.yamlYou can check to see when everything is up and running using kubectl get pods -n temporal and checking that all pods are showing STATUS as RUNNING.
kubectl get pods -n temporalOnce everything is up you can open the Temporal Web UI in your browser. You can use port forwarding to be able to reach the Temporal Web UI from your workstation using the kubectl port-forward ... command. Leave this running in a terminal window and then visit http://localhost:8088 in your browser.
kubectl port-forward -n temporal services/temporal-web 8088:8088You can also interact with the Server using a preconfigured CLI (tctl).
First create an alias for tctl:
alias tctl="kubectl exec -n temporal deployment/temporal-admin-tools -- tctl"The following is an example of how to register a new namespace test-namespace with 1 day of retention:
tctl --ns test-namespace namespace register -rd 1You can find our tctl docs on docs.temporal.io.
Get started building Workflows with a Go sample, Java sample, or write your own using one of the SDKs.
The manifests set at k8s/temporal-default installs a PostgreSQL database, an Elasticsearch instance and Temporal Server.
The other manifest directories in the repo spin up instances of the Temporal Server using different databases and dependencies.
For example you can run the Temporal Server with MySQL and Elastic Search with this command:
kubectl create namespace temporal
kubectl apply -n temporal -R -f https://raw.githubusercontent.com/temporalio/docker-compose/main/k8s/temporal-mysql-es.yamlHere is a list of available manifest sets and the dependencies they install.
