# Ruby gems in the Package Registry **(FREE)**
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/803) in [GitLab Free](https://about.gitlab.com/pricing/) 13.10.
|
|
|
|
WARNING:
|
|
The Ruby gems registry for GitLab is under development and isn't ready for production use due to
|
|
limited functionality.
|
|
|
|
You can publish Ruby gems in your project's Package Registry, then install the packages when you
|
|
need to use them as a dependency. Although you can push gems to the registry, you cannot install
|
|
them from the registry. However, you can download `gem` files directly from the Package Registry's
|
|
UI, or by using the [API](../../../api/packages/rubygems.md#download-a-gem-file).
|
|
|
|
For documentation of the specific API endpoints that the Ruby gems and Bundler package manager
|
|
clients use, see the [Ruby gems API documentation](../../../api/packages/rubygems.md).
|
|
|
|
## Enable the Ruby gems registry
|
|
|
|
The Ruby gems registry for GitLab is behind a feature flag that is disabled by default. GitLab
|
|
administrators with access to the GitLab Rails console can enable this registry for your instance.
|
|
|
|
To enable it:
|
|
|
|
```ruby
|
|
Feature.enable(:rubygem_packages)
|
|
```
|
|
|
|
To disable it:
|
|
|
|
```ruby
|
|
Feature.disable(:rubygem_packages)
|
|
```
|
|
|
|
To enable or disable it for specific projects:
|
|
|
|
```ruby
|
|
Feature.enable(:rubygem_packages, Project.find(1))
|
|
Feature.disable(:rubygem_packages, Project.find(2))
|
|
```
|
|
|
|
## Create a Ruby Gem
|
|
|
|
If you need help creating a Ruby gem, see the [RubyGems documentation](https://guides.rubygems.org/make-your-own-gem/).
|
|
|
|
## Authenticate to the Package Registry
|
|
|
|
Before you can push to the Package Registry, you must authenticate.
|
|
|
|
To do this, you can use:
|
|
|
|
- A [personal access token](../../../user/profile/personal_access_tokens.md)
|
|
with the scope set to `api`.
|
|
- A [deploy token](../../project/deploy_tokens/index.md) with the scope set to
|
|
`read_package_registry`, `write_package_registry`, or both.
|
|
- A [CI job token](#authenticate-with-a-ci-job-token).
|
|
|
|
### Authenticate with a personal access token or deploy token
|
|
|
|
To authenticate with a personal access token, create or edit the `~/.gem/credentials` file and add:
|
|
|
|
```ini
|
|
---
|
|
https://gitlab.example.com/api/v4/projects/<project_id>/packages/rubygems: '<your token>'
|
|
```
|
|
|
|
- `<your token>` must be the token value of either your personal access token or deploy token.
|
|
- Your project ID is on your project's home page.
|
|
|
|
### Authenticate with a CI job token
|
|
|
|
To work with RubyGems commands within [GitLab CI/CD](../../../ci/README.md),
|
|
you can use `CI_JOB_TOKEN` instead of a personal access token or deploy token.
|
|
|
|
For example:
|
|
|
|
```yaml
|
|
image: ruby:latest
|
|
|
|
run:
|
|
script:
|
|
```
|
|
|
|
You can also use `CI_JOB_TOKEN` in a `~/.gem/credentials` file that you check in to
|
|
GitLab:
|
|
|
|
```ini
|
|
---
|
|
https://gitlab.example.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/rubygems: '${env.CI_JOB_TOKEN}'
|
|
```
|
|
|
|
## Push a Ruby gem
|
|
|
|
Prerequisites:
|
|
|
|
- You must [authenticate to the Package Registry](#authenticate-to-the-package-registry).
|
|
- The maximum allowed gem size is 3 GB.
|
|
|
|
To push your gem, run a command like this one:
|
|
|
|
```shell
|
|
gem push my_gem-0.0.1.gem --host <host>
|
|
```
|
|
|
|
Note that `<host>` is the URL you used when setting up authentication. For example:
|
|
|
|
```shell
|
|
gem push my_gem-0.0.1.gem --host https://gitlab.example.com/api/v4/projects/1/packages/rubygems
|
|
```
|
|
|
|
This message indicates that the gem uploaded successfully:
|
|
|
|
```plaintext
|
|
Pushing gem to https://gitlab.example.com/api/v4/projects/1/packages/rubygems...
|
|
{"message":"201 Created"}
|
|
```
|
|
|
|
To view the published gem, go to your project's **Packages & Registries** page. Gems pushed to
|
|
GitLab aren't displayed in your project's Packages UI immediately. It can take up to 10 minutes to
|
|
process a gem.
|
|
|
|
### Pushing gems with the same name or version
|
|
|
|
You can push a gem if a package of the same name and version already exists.
|
|
Both are visible and accessible in the UI. However, only the most recently
|
|
pushed gem is used for installs.
|
|
|
|
## Install a Ruby gem
|
|
|
|
The Ruby gems registry for GitLab is under development, and isn't ready for production use. You
|
|
cannot install Gems from the registry. However, you can download `.gem` files directly from the UI
|
|
or by using the [API](../../../api/packages/rubygems.md#download-a-gem-file).
