Tekton Hub

TektonHub custom resource allows user to install and manage Tekton Hub.

TektonHub is an optional component and currently cannot be installed through TektonConfig. It has to be installed seperately. It is available for both Kubernetes and OpenShift platform.

To install Tekton Hub on your cluster follow steps as given below:

Note :

Initially user had to enable Tekton Hub Authentication, get the Hub token with required scopes and then hit the catalog refresh api to load the resources in the database.
Now user doesn’t needs to enable login mechanism to get the resources populated in the database as resources will be automatically populated in the database when the api is up and running
Resources in the hub db will be also automatically refreshed with the updated data with the time which is specified in the Hub CR i.e catalogRefreshInterval: 30m. Default time interval is 30m
If you are using your database instead of default one then secret name for the database should be tekton-hub-db and you need to create the secret in your targetNamespace with the following keys
The dependency of config.yaml from git is removed and complete config data is moved into API configMap. Now user can add the config data i.e. categories, catalogs, scopes and defaultScopes in the Hub CR itself. If user does not add any data then default data provided by Hub in the API configMap will be used

apiVersion: v1
kind: Secret
metadata:
  name: tekton-hub-db
  labels:
    app: tekton-hub-db
type: Opaque
stringData:
  POSTGRES_HOST: <The name of the host of the database>
  POSTGRES_DB: <Name of the database>
  POSTGRES_USER: <The name of user account>
  POSTGRES_PASSWORD: <The password of user account>
  POSTGRES_PORT: <The port that the database is listening on>

This is how TektonHub CR looks

apiVersion: operator.tekton.dev/v1alpha1
kind: TektonHub
metadata:
  name: hub
spec:
  targetNamespace:
  # <namespace> in which you want to install Tekton Hub. Leave it blank if in case you want to install
  # in default installation namespace ie `openshift-pipelines` in case of OpenShift and `tekton-pipelines` in case of Kubernetes
  db:                      # 👈 Optional: If user wants to use his database
    secret: tekton-hub-db  # 👈 Name of db secret should be `tekton-hub-db`

  categories:                     # 👈 Optional: If user wants to use his categories 
    - Automation
    - Build Tools
    - CLI
    - Cloud
    - Code Quality
    - ...

  catalogs:                       # 👈 Optional: If user wants to use his catalogs
    - name: tekton
      org: tektoncd
      type: community
      provider: github
      url: https://github.com/tektoncd/catalog
      revision: main

  scopes:                         # 👈 Optional: User can define his scopes  
    - name: agent:create
      users: [abc, qwe, pqr]
    - name: catalog:refresh
      users: [abc, qwe, pqr]
    - name: config:refresh
      users: [abc, qwe, pqr]

  default:                       # 👈 Optional: User can define his default scopes
    scopes:
      - rating:read
      - rating:write

  api:
    catalogRefreshInterval: 30m     # After every 30min catalog resources in the hub db would be refreshed to get the updated data from the catalog. Supported time units are As(A seconds), Bm(B minutes) Ch(C hours), Dd(D days) and Ew(E weeks).

You can install Tekton Hub by running the command
```
kubectl apply -f <name>.yaml
```

Check the status of installation using following command

$ kubectl get tektonhub.operator.tekton.dev
NAME   VERSION   READY   REASON   APIURL                  UIURL
hub    v1.8.0    True             https://api.route.url   https://ui.route.url

Create the secrets for the API before we install Tekton Hub. By default, Tekton Hub expects this secret to have the following properties:
- namespace: TargetNamespace defined in TektonHub CR at the time of applying. If nothing is specified then based on platform create the secrets. openshift-pipelines in case of OpenShift, tekton-pipelines in case of Kubernetes.
- name: tekton-hub-api
- contains the fields:
  - GH_CLIENT_ID=<github-client-id>
  - GH_CLIENT_SECRET=<github-client-secret>
  - GL_CLIENT_ID=<gitlab-client-id>
  - GL_CLIENT_SECRET=<gitlab-client-secret>
  - BB_CLIENT_ID=<bitbucket-client-id>
  - BB_CLIENT_SECRET=<bitbucket-client-secret>
  - JWT_SIGNING_KEY=<jwt-signing-key>
  - ACCESS_JWT_EXPIRES_IN=<time(eg 30d)>
  - REFRESH_JWT_EXPIRES_IN=<time(eg 30d)>
  - GHE_URL=<github enterprise url(leave it blank if not using github enterprise>
  - GLE_URL=<gitlab enterprise url(leave it blank if not using gitlab enterprise>
Note 1: For more details please refer to here

Once the secrets are created now we need to understand how TektonHub CR looks.

apiVersion: operator.tekton.dev/v1alpha1
kind: TektonHub
metadata:
  name: hub
spec:
  targetNamespace:
  # <namespace> in which you want to install Tekton Hub. Leave it blank if in case you want to install
  # in default installation namespace ie `openshift-pipelines` in case of OpenShift and `tekton-pipelines` in case of Kubernetes
  db:                      # 👈 Optional: If user wants to use his database
    secret: tekton-hub-db  # 👈 Name of db secret should be `tekton-hub-db`

  categories:                     # 👈 Optional: If user wants to use his categories 
    - Automation
    - Build Tools
    - CLI
    - Cloud
    - Code Quality
    - ...

  catalogs:                       # 👈 Optional: If user wants to use his catalogs
    - name: tekton
      org: tektoncd
      type: community
      provider: github
      url: https://github.com/tektoncd/catalog
      revision: main

  scopes:                         # 👈 Optional: User can define his scopes 
    - name: agent:create
      users: [abc, qwe, pqr]
    - name: catalog:refresh
      users: [abc, qwe, pqr]
    - name: config:refresh
      users: [abc, qwe, pqr]

  default:                       # 👈 Optional: User can define his default scopes
    scopes:
      - rating:read
      - rating:write

  api:
    catalogRefreshInterval: 30m     # After every 30min catalog resources in the hub db would be refreshed to get the updated data from the catalog. Supported time units are As(A seconds), Bm(B minutes) Ch(C hours), Dd(D days) and Ew(E weeks).

After configuring the TektonHub spec you can install Tekton Hub by running the command
```
kubectl apply -f <name>.yaml
```

Check the status of installation using following command

$ kubectl get tektonhub.operator.tekton.dev
NAME   VERSION   READY   REASON   APIURL                  UIURL
hub    v1.6.0    True             https://api.route.url   https://ui.route.url
