## Screenshots
## Setup
1. Install packages:
```bash
# From your Backstage root directory
yarn --cwd packages/app add @immobiliarelabs/backstage-plugin-gitlab
yarn --cwd packages/backend add @immobiliarelabs/backstage-plugin-gitlab-backend
```
### Setup Frontend Plugin
1. Add a new GitLab tab to the entity page.
> NOTE: By default the EntityGitlabContent does not load the README, see the Optional section.
`packages/app/src/components/catalog/EntityPage.tsx`
```tsx
// packages/app/src/components/catalog/EntityPage.tsx
import {
isGitlabAvailable,
EntityGitlabContent,
} from '@immobiliarelabs/backstage-plugin-gitlab';
// Farther down at the serviceEntityPage declaration
const serviceEntityPage = (
{/* Place the following section where you want the tab to appear */}
);
```
2. (**Optional**) Add the GitLab cards to the Overview tab on the entity page.
`packages/app/src/components/catalog/EntityPage.tsx`
```tsx
// packages/app/src/components/catalog/EntityPage.tsx
import {
isGitlabAvailable,
EntityGitlabContent,
EntityGitlabLanguageCard,
EntityGitlabMergeRequestsTable,
EntityGitlabMergeRequestStatsCard,
EntityGitlabPeopleCard,
EntityGitlabPipelinesTable,
EntityGitlabReadmeCard,
EntityGitlabReleasesCard,
} from '@immobiliarelabs/backstage-plugin-gitlab';
//Farther down at the overviewContent declaration
//You can add only selected widgets or all of them.
const overviewContent = (
);
```
3. Add the integration:
`app-config.yaml` add the integration for gitlab:
```yaml
integrations:
gitlab:
- host: gitlab.com
token: ${GITLAB_TOKEN}
```
**Note:** You can have more than one GitLab instance.
### Setup Backend Plugin
> NOTE: Currently backstage supports a new way to register backend plugins, see the [Register To The New Backend System](#register-to-the-new-backend-system) section.
1. Add the GitLab Filler Processor, this allows auto-filling of the annotations like the project id and slug:
`packages/backend/src/plugins/catalog.ts`
```ts
// packages/backend/src/plugins/catalog.ts
import { GitlabFillerProcessor } from '@immobiliarelabs/backstage-plugin-gitlab-backend';
export default async function createPlugin(
env: PluginEnvironment
): Promise {
const builder = await CatalogBuilder.create(env);
//...
// Add this line
builder.addProcessor(new GitlabFillerProcessor(env.config));
//...
const { processingEngine, router } = await builder.build();
await processingEngine.start();
return router;
}
```
This allows auto-filling of the annotations.
2. Add the `gitlab` route by creating the file `packages/backend/src/plugins/gitlab.ts`:
`packages/backend/src/plugins/gitlab.ts`
```ts
// packages/backend/src/plugins/gitlab.ts
import { PluginEnvironment } from '../types';
import { Router } from 'express-serve-static-core';
import { createRouter } from '@immobiliarelabs/backstage-plugin-gitlab-backend';
export default async function createPlugin(
env: PluginEnvironment
): Promise {
return createRouter({
logger: env.logger,
config: env.config,
});
}
```
then you have to add the route as follows:
`packages/backend/src/index.ts`
```ts
// packages/backend/src/index.ts
import gitlab from './plugins/gitlab';
async function main() {
//...
const gitlabEnv = useHotMemoize(module, () => createEnv('gitlab'));
//...
apiRouter.use('/gitlab', await gitlab(gitlabEnv));
//...
}
```
3. (**Optional**): You can also add plugin configurations in `app-config.yaml` file:
`app-config.yaml`
```yaml
# app-config.yaml
# ...
gitlab:
# Default path for CODEOWNERS file
# Default: CODEOWNERS
defaultCodeOwnersPath: .gitlab/CODEOWNERS
# Default path for README file
# Default: README.md
defaultReadmePath: .gitlab/README.md
# Entity Kinds to witch the plugin works, if you want to render gitlab
# information for one Kind you have to add it in this list.
# Default: ['Component']
allowedKinds: ['Component', 'Resource']
# This parameter controls SSL Certs verification
# Default: true
proxySecure: false
# Activate Oauth/OIDC
# Default: false
useOAuth: false
```
### Extra OIDC/OAuth
By default, this plugin utilizes the token specified in the configuration file `app-config.yaml` under the key: `integrations.gitlab[i].token`. However, you can opt out of using this token by activating OIDC as shown below:
```yaml
gitlab:
useOAuth: true
```
**Note:**: To use OIDC you have to configure the `@backstage/plugin-auth-backend-module-gitlab-provider` plugin.
**Note:**: OIDC does not allow multi GitLab instances!
### Register To The New Backend System
If you're already using the [New Backend System](https://backstage.io/docs/backend-system/), registering backend plugins will become much easier:
`packages/backend/src/index.ts`
```ts
// packages/backend/src/index.ts
import {
gitlabPlugin,
catalogPluginGitlabFillerProcessorModule,
} from '@immobiliarelabs/backstage-plugin-gitlab-backend';
async function start() {
const backend = createBackend();
// ...
backend.add(gitlabPlugin);
backend.add(catalogPluginGitlabFillerProcessorModule);
// ...
}
```
## Annotations
By default, the plugin automatically shows the project info corresponding to the location of the `catalog.yaml` file. But you could need some time to force another project, you can do it with the annotations `gitlab.com/project-id` or `gitlab.com/project-slug`:
```yaml
# Example catalog-info.yaml entity definition file
apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
# ...
annotations:
gitlab.com/project-id: 'project-id' #1234. This must be in quotes and can be found under Settings --> General
# or
gitlab.com/project-slug: 'project-slug' # group_name/project_name
# or
gitlab.com/instance: gitlab.internal.abcd # abcd, represents local instance used
spec:
type: service
# ...
```
It's possible to disable the GitLab plugins and cards by setting these annotations to an empty string.
This is useful if the entity (catalog-info.yaml) is hosted on GitLab but the actual source code is hosted
somewhere else or GitLab isn't used for issue tracking.
```yaml
# Example catalog-info.yaml entity definition file
apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
# ...
annotations:
gitlab.com/instance: '' # don't show the issue and merge requests cards
gitlab.com/project-slug: ''
spec:
type: service
# ...
```
### Code owners file
The plugins support also the `gitlab.com/codeowners-path` annotation:
```yaml
# Example catalog-info.yaml entity definition file
apiVersion: backstage.io/v1alpha1
kind: Component
metadata:
# ...
annotations:
# You can change the CODEOWNERS path
# if it is not passed default specified in `app-config.yaml` is used
gitlab.com/codeowners-path: 'somewhere/CODEOWNERS'
spec:
type: service
# ...
```
## Old/New GitLab Versions
If you have an old GitLab version, or a new one, we allow you to extend the GitLab Client as follows:
`packages/app/src/api.ts`
```ts
import { GitlabCIApiRef } from '@immobiliarelabs/backstage-plugin-gitlab';
import { CustomGitlabCIClient } from '@immobiliarelabs/backstage-plugin-gitlab';
import { discoveryApiRef, configApiRef } from '@backstage/core-plugin-api';
import { CustomGitlabCIClient } from 'packages/app/src/myCustomClient.ts';
export const apis: AnyApiFactory[] = [
createApiFactory({
api: GitlabCIApiRef,
deps: { configApi: configApiRef, discoveryApi: discoveryApiRef },
factory: ({ configApi, discoveryApi }) =>
CustomGitlabCIClient.setupAPI({
discoveryApi,
codeOwnersPath: configApi.getOptionalString(
'gitlab.defaultCodeOwnersPath'
),
readmePath: configApi.getOptionalString(
'gitlab.defaultReadmePath'
),
}),
}),
];
```
`packages/app/src/myCustomClient.ts`
```ts
import { GitlabCIClient } from '@immobiliarelabs/backstage-plugin-gitlab';
export class CustomGitlabCIClient extends GitlabCIClient {
// Override methods
async getPipelineSummary(projectID: string | undefined): Promise {
this.callApi(...)
.
.
.
}
}
```
see [here](./packages/gitlab/src/api/GitlabCIClient.ts).
