The temporal cloud cli.

tcld (Beta)

A cli tool for managing Temporal Cloud namespaces.

This cli tool is currently in beta and access to Temporal Cloud via the cli is restricted. Please reach out to temporal-cloud support for more information.

Installation

Build from source

1. Verify that you have Go 1.18+ installed. If go is not installed, follow instructions on the Go website.

go version

2. Clone the tcld repository and run make.

git clone https://github.com/temporalio/tcld.git
cd tcld
make

3. Copy the tcld executable to any directory that appears in the PATH environment variable; for example, /usr/local/bin/.

cp tcld /usr/local/bin/tcld

4. Run tcld version to check if it worked.

tcld version

Authentication and Login

In order to use the cli you must first login by running the following command:

tcld login

You will be sent a link to confirm your device code and login. After logging in, you are now authenticated and can make requests with this cli.

Namespace Management

List namespaces user has access to:

tcld namespace list

Get namespace information:

tcld namespace get -n <namespace>

Update the CA certificate:

tcld namespace update accepted-client-ca set -n <namespace> --ca-certificate-file <ca-pem-filepath>

⚠️ If the update removes a certificate, any clients (tctl/workers) still using the removed certificate will fail to connect to the namespace after the update completes.

Add new search attributes:

tcld namespace update search-attributes add -n <namespace> --sa "<attribute-name>=<search-attribute-type>" --sa "<attribute-name>=<search-attribute-type>"

Supported search attribute types: SearchAttributeTypeKeyword SearchAttributeTypeText SearchAttributeTypeInt SearchAttributeTypeDouble SearchAttributeTypeDatetime SearchAttributeTypeBool

Rename existing search attribute:

tcld namespace update search-attributes rename -n <namespace> --existing-name <existing-attribute-name> --new-name <new-attribute-name>

⚠️ Any workflows that are using the old search attribute name will fail after the update.

Asynchronous Operations

Any update operations making changes to the namespaces hosted on Temporal Cloud are asynchronous. Such operations are tracked using a request-id that can be passed in when invoking the update operation or will be auto-generated by the server if one is not specified. Once an asynchronous request is initiated, a request-id is returned. Use the request get command to query the status of an asynchronous request.

tcld request get -r <request-id> -n <namespace>
