Add Namespace support to the API module and the CLI commands (#6874)
Also update the Docs and fixup the HTTP API to return proper errors when someone attempts to use Namespaces with an OSS agent.

Namespace - HTTP API

~> Enterprise Only! These API endpoints and functionality only exists in Consul Enterprise. This is not present in the open source version of Consul.

The functionality described here is available only in Consul Enterprise version 1.7.0 and later.

Create a Namespace

This endpoint creates a new ACL token.

Method Path Produces
PUT /namespace application/json

The table below shows this endpoint's support for blocking queries, consistency modes, agent caching, and required ACLs.

Blocking Queries Consistency Modes Agent Caching ACL Required
NO none none operator:write

Parameters

  • Name (string: <required>) - The namespaces name. This must be a valid DNS hostname label.

  • Description (string: "") - Free form namespaces description.

  • ACLs (object: <optional>) - ACL configurations for this namespace. Rules from default policies and roles will be used only when there are no rules from directly linked policies, roles and service identities that are for the target resource and segment. Therefore if a directly linked policy grants read access to some resource and a default policy grants write access, the effective access for the token will be read due to the default policies not being checked. When there is no rule concerning the resource in either the directly linked policies, roles and service identities nor in those linked by the defaults, then the agents default policy configuration will be used for making the enforcement decision.

    • PolicyDefaults (array<ACLLink>) - This is the list of default policies that should be applied to all tokens created in this namespace. The ACLLink struct is an object with an "ID" and/or "Name" field to identify a policy. When a name is used instead of an ID, Consul will resolve the name to an ID and store that internally.

    • RoleDefaults (array<ACLLink>) - This is the list of default roles that should be applied to all tokens created in this namespace. The ACLLink struct is an object with an "ID" and/or "Name" field to identify a policy. When a name is used instead of an ID, Consul will resolve the name to an ID and store that internally.

  • Meta (map<string|string>: <optional>) - Specifies arbitrary KV metadata to associate with the namespace.

Delete a Namespace

This endpoint marks a Namespace for deletion. Once marked Consul will deleted all the associated Namespaced data in the background. Only once all associated data has been deleted will the Namespace actually disappear. Until then, further reads can be performed on the namespace and a DeletedAt field will now be populated with the timestamp of when the Namespace was marked for deletion.

Method Path Produces
DELETE /namespace/:name N/A

This endpoint will return no data. Success or failure is indicated by the status code returned.

The table below shows this endpoint's support for blocking queries, consistency modes, agent caching, and required ACLs.
