Building Gorya

Software requirements

• go 1.20+
• git

Setup your environments

By default, in-mem sqlite is used but MySQL is recommended for production setup.

Option 1: Set up with docker-compose

1. Create a new directory for project if not exists.

mkdir -p ~/go/src/github.com/nduyphuong/gorya

2. Clone the source code

cd ~/go/src/github.com/nduyphuong/gorya
git clone https://github.com/nduyphuong/gorya

3. Set up the stack with docker

cd ~/go/src/github.com/nduyphuong/gorya
docker-compose up -d

4. Setup keycloak

Client:

Make sure that Access Type is public and Web Origins is http://localhost:3000 or *

Roles:

Gorya rely on keycloak for doing identity and access management. List of role to configure for gorya client:

• add-policy
• add-schedule
• delete-policy
• delete-schedule
• get-policy
• get-schedule
• get-timezone
• list-policy
• list-schedule

Github:

Create a github oauth app for keycloak.

Keycloak github identity provider setting:

autonumber
actor U as User
participant UI as Gorya UI
participant K as Keycloak
participant IDP as Upstream Identity Provider
participant BE as Gorya Backend

U->>UI: Unauthenticated user
UI->>K: Redirects to Keycloak
K->>U: Login page
U->>K: Choose Identity Provider
K->>U: Return Identity Provider login page
U->>IDP: Enter credential
IDP->>UI: Return JWT Token
UI->>UI: Extract access token
UI->>BE: Send request with authorization header
BE->>K: Verify access token, with associated role in keycloak
BE->>UI: Response

Option 2: Set up with helm

TBD

How it works
