[id="managing-registry-artifacts-cli_{context}"]
= Managing {registry} content using the command-line interface

[role="_abstract"]
You can use the {registry} command-line interface (CLI) to manage {registry} content from the command line. The CLI provides commands for managing CLI contexts and artifact groups.

ifndef::service-registry-downstream[]
[NOTE]
====
The CLI is currently in *dev-preview* status. The CLI supports Linux (bash) and macOS (zsh). Windows is not supported yet. The CLI currently implements only group management commands. Future releases will include additional commands.
====

[IMPORTANT]
====
The CLI does not yet support authentication. You can only use the CLI with {registry} instances that do not require authentication.
====
endif::[]

ifdef::service-registry-downstream[]
[IMPORTANT]
====
The CLI is a Technology Preview feature. Technology Preview features are not supported with Red{nbsp}Hat production service level agreements (SLAs) and might not be functionally complete. Red{nbsp}Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

.Prerequisites
* You have installed {registry}.
* You have Java 11 or higher installed.
* You have access to a bash shell (Linux) or zsh shell (macOS).

[id="installing-registry-cli_{context}"]
== Installing the {registry} CLI

[role="_abstract"]
You can install the {registry} CLI to interact with {registry} from the command line. The CLI comes as a .zip file that has the executable program and required dependencies.

.Prerequisites
* You have Java 11 or higher installed on your system.
* You have access to a bash shell (Linux) or zsh shell (macOS).

.Procedure
ifndef::service-registry-downstream[]
. Download the latest `apicurio-registry-cli-VERSION.zip` file from the https://github.com/Apicurio/apicurio-registry/releases[{registry} GitHub Releases page]. Alternatively, you can download the CLI from the https://search.maven.org/search?q=g:io.apicurio%20AND%20a:apicurio-registry-cli[Maven Central repository] by searching for `apicurio-registry-cli`.
endif::[]
ifdef::service-registry-downstream[]
. Download the CLI .zip file from the Red{nbsp}Hat Customer Portal.
endif::[]
. Extract the downloaded file to a location of your choice:
+
[source,bash]
----
$ unzip apicurio-registry-cli-VERSION.zip -d ~/apicurio-cli
----
. Install the CLI for the current user:
+
[source,bash]
----
$ cd ~/apicurio-cli
$ ./acr install
----
+
This command installs the CLI executable to `$HOME/bin` and creates a configuration directory at `$HOME/.apicurio/apicurio-registry-cli`. The command also updates your `~/.bashrc` file (Linux) or `~/.zshrc` file (macOS) and configures shell completions.
. Reload your shell configuration:
+
On Linux:
+
[source,bash]
----
$ source ~/.bashrc
----
+
On macOS:
+
[source,bash]
----
$ source ~/.zshrc
----
. Verify the installation:
+
[source,bash]
----
$ acr --help
----

[id="configuring-registry-cli-contexts_{context}"]
== Configuring {registry} CLI contexts

[role="_abstract"]
An {registry} CLI context stores the registry URL and identifies the instance that the CLI commands target. You can create many contexts and switch between them as needed, similar to how you use contexts in {kubernetes}.

.Procedure
. Create a new context for your {registry} instance:
+
[source,bash,subs="+quotes"]
----
$ acr context create _CONTEXT_NAME_ _REGISTRY_URL_
----
+
For example:
+
[source,bash]
----
$ acr context create dev http://localhost:8080
----
+
The CLI automatically switches to the newly created context.
. List all configured contexts:
+
[source,bash]
----
$ acr context
----
+
.Example output
[source]
----
Current context is 'default'.
ID        Registry URL
--------  ---------------------
default*  http://localhost:8080
----
+
The asterisk (*) indicates the current active context.
. Optional: Create additional contexts without switching to them:
+
[source,bash]
----
$ acr context create prod http://registry.example.com --no-switch-current
----
. Delete a context that you no longer need:
+
[source,bash,subs="+quotes"]
----
$ acr context delete _CONTEXT_NAME_
----


[id="managing-groups-using-registry-cli_{context}"]
== Managing groups using the CLI

[role="_abstract"]
You can use the CLI to create, list, update, and delete artifact groups in {registry}. Groups offer a way to organize related artifacts.

.Prerequisites
* You have configured at least one CLI context.

=== Listing groups

To list all groups in the registry:

[source,bash]
----
$ acr group
----

You can use pagination options for large result sets:

[source,bash]
----
$ acr group --page 1 --size 50
----

=== Creating a group

To create a new group:

[source,bash,subs="+quotes"]
----
$ acr group create _GROUP_ID_
----

You can include a description and labels:

[source,bash]
----
$ acr group create my-schemas --description "Production schemas" --label env=prod --label team=platform
----

=== Getting group details

To get details for a specific group:

[source,bash,subs="+quotes"]
----
$ acr group get _GROUP_ID_
----

For example:

[source,bash]
----
$ acr group get my-schemas
----

=== Updating a group

To update a group description:

[source,bash]
----
$ acr group update my-schemas --description "Updated description"
----

To add or update labels:

[source,bash]
----
$ acr group update my-schemas --set-label env=staging --set-label owner=alice
----

To delete labels:

[source,bash]
----
$ acr group update my-schemas --delete-label env
----

=== Deleting a group

To delete a group:

[source,bash,subs="+quotes"]
----
$ acr group delete _GROUP_ID_
----

[NOTE]
====
You must configure {registry} with `apicurio.rest.deletion.group.enabled=true` to allow group deletions.
====

To delete a group that has artifacts, use the `--force` option:

[source,bash]
----
$ acr group delete my-schemas --force
----

[NOTE]
====
Using `--force` deletes the group and all artifacts it contains. Use this option with caution.
====


[id="registry-cli-output-formats_{context}"]
== CLI output formats and pagination

[role="_abstract"]
The CLI supports different output formats and pagination options for managing large result sets.

.Output formats
The CLI supports the following output formats:

* `table` (default) - Human-readable tabular format
* `json` - Machine-readable JSON format

To specify the output format, use the `--output-type` or `-o` option:

[source,bash]
----
$ acr group --output-type json
$ acr group get my-schemas -o json
----

.Pagination
For commands that return lists, you can use pagination options:

* `--page` - The page number (starting from 1)
* `--size` - The number of items per page

For example:
[source,bash]
----
$ acr group --page 2 --size 25
----
