tctl v1.17 admin command reference

View Markdown
tctl is deprecated

The tctl command line utility has been deprecated and is no longer actively supported. We recommend transitioning to Temporal CLI for continued use and access to new features.

Thank you for being a valued part of the Temporal community.

A tctl admin command allows the user to run admin operations.

Modifiers:

--help​

tctl admin [--help | -h]

cluster​

The tctl admin cluster command runs the administrator-level operations on a given Cluster.

tctl admin cluster command [command modifiers] [arguments...]

add_search_attributes​

The tctl admin cluster add-search-attributes command allows Search Attributes to be added to a Cluster. Custom Search Attributes can be used to make a Cluster more identifiable.

info

Due to Elasticsearch limitations, you can only add new custom Search Attributes. Existing Search Attributes cannot be renamed or removed from the Elasticsearch index.

Use this command to add custom Search Attributes to your Temporal Cluster:

tctl admin cluster add-search-attributes --name <SearchAttributeName> --type <SearchAttributeValueType>
info

If you are adding custom Search Attributes to a Cluster running from the docker-compose-es.yml file in the temporalio/docker-compose repo, make sure to increase the Docker memory to more than 6 GB.

--skip_schema_update​

Allows the user to skip the Elasticsearch index schema update.

info

This will only register in metadata.

--name​

The name of the Search Attribute to add. Names can have multiple values.

Search Attribute names are case sensitive.

--type​

The type of Search Attribute to add. Multiple values can be added at once.

Values: Text, Keyword, Int, Double, Bool, Datetime

describe​

The tctl admin cluster describe command provides information for the current Cluster.

The following modifier changes the behavior of the command:

--cluster_value​

The name of the remote Cluster within the current Cluster.

This modifier is optional, and can default to the return of current Cluster information.

get_search_attributes​

The tctl admin cluster get_search_attributes command retrieves existing Search Attributes for a given Cluster.

The following modifier will change the behavior of the command:

--print_json​

Prints the existing search attributes in JSON format.

list​

The tctl admin cluster list command lists Cluster information on the given Cluster.

Default: 100

The modifier below changes the behavior of the command:

--pagesize​

The size of the page that the list is printed on.

remove_remote_cluster​

The tctl admin cluster remove_remote_cluster command removes remote Cluster information on the given Cluster.

The modifier below changes the behavior of the operation:

--cluster​

The name of the remote Cluster to remove.

remove_search_attributes​

The Temporal tctl documentation covers version 1.17 of the Temporal CLI.

The tctl admin cluster remove-search-attributes command removes custom Search Attribute metadata from a Cluster. This operation has no effect on Elasticsearch index schema.

Use the following command to remove a Search Attribute from a Cluster's metadata:

tctl admin cluster remove-search-attributes --name <SearchAttributeKey>

Only custom Search Attributes can be removed from a Cluster's metadata. Default Search Attributes cannot be removed.

Removing a Search Attribute removes it from the Cluster's metadata but does not remove it from the Elasticsearch index. This means that the Search Attribute can be added back later as the same type. After a Search Attribute has been added to the Elasticsearch index, it cannot be changed.

The following modifier changes the behavior of the operation:

--name​

Name of the Search Attribute to remove.

upsert_remote_cluster​

The tctl admin cluster upsert_remote_cluster command adds or updates remote Cluster information in the current Cluster.

--frontend_address​

The remote Cluster frontend address.
