Instruction

Build on Java 11

Build proto before other modules

1. Run auth app

No dependencies

2. Run app1

No dependencies

3. Run app2

Requires redis and mongo

3.1 Run following docker containers

    docker run --name mongo -p 27017:27017 -d mongo
    docker run --name redis -p 6379:6379 -d redis

3.2 Create capped "user" collection

    db.createCollection("logs", {capped: true, size: 4096, max:5})

4. Run web (nginx)

Web is Nginx HTTP server:

Caching of static content
Authorization (list of API and roles) using JWT tokens
Reverse proxy

4.1 Build nginx config

To simplify configuration there is python script which creates nginx.conf

Nginx config requires authorization mapping data (role to URL mapping). This mapping is done with *.yml files (one file per application/domain name)

Mapping configuration *.yml

    subdomain-env: app1.local.com
    static-root: /static/app1
    
    api:
      - context-path: /api
        upstream-name: app1
        upstream-url: host.docker.internal:8091
        locations:
          - url: /test1/{id}
            roles: ['TEST_ROLE']
          - url: /test2
            roles: ['TEST_ROLE']
          - url: /test3
            roles: ['TEST_ROLE']
          - url: /test4
            roles: ['TEST_ROLE']
          - url: /test5
            roles: ['TEST_ROLE']
          - url: /test6
            roles: ['TEST_ROLE']
      - context-path: /api/auth
        upstream-name: authapp
        upstream-url: host.docker.internal:8090
        locations:
          - url: /oauth/token
            security: none
            docker run --name ng -p8080:8080 ng

Explanation by line

subdomain-env: app1.local.com

Application domain name. Nginx will use this domain name to resolve application and redirect to proper endpoint.

static-root: /static/app1

Static files location (All *.html, *.css, *.js and images)

 - context-path: /api

Nginx resolves upstream endpoint by context path. This way we can hide auth application behind app1 domain name.

upstream-name: app1

Application upstream id.

upstream-url: host.docker.internal:8091

Application upstream url ("host.docker.internal" refers to docker parent host)

locations:
  - url: /test1/{id}
    roles: ['TEST_ROLE']

Authorization mapping role to URL (/test1/... is available to TEST_ROLE role)

Build config

Requires docker:

    cd /nginx/config
    docker build -t cg .
    docker run --rm cg

Manually copy file content into nginx.conf file and place it into /nginx/web

4.2 Run Nginx

After nginx.conf is ready

    cd /nginx/web
    docker build --no-cache -t ng .
    docker run --rm -p8080:8080 --name ng ng

Other

Generate RSA keys

Asymmetric keys generation:

    keytool -genkeypair -alias jwt -keyalg RSA -keypass 123456 -keystore jwt.jks -storepass 123456

Test endpoints

Refer to controllers inside app1 and app2

Direct example

http://localhost:8091/test1/1
http://localhost:8092/test1/1

Through nginx example

header: Authorization: Basic [access token]

http://app1.local.com:8080/api/test1/1
http://app2.local.com:8080/api/test1/1

Authentication

Directly to auth app

    POST /oauth/token?grant_type=password&amp;client_id=browser&amp;client_secret=asdf HTTP/1.1
    Host: localhost:8090
    Cache-Control: no-cache
    Postman-Token: b37c7d50-e9e3-2863-59a7-51e0a07c88cf
    Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
    
    ------WebKitFormBoundary7MA4YWxkTrZu0gW
    Content-Disposition: form-data; name="username"
    
    login
    ------WebKitFormBoundary7MA4YWxkTrZu0gW
    Content-Disposition: form-data; name="password"
    
    password
    ------WebKitFormBoundary7MA4YWxkTrZu0gW--

Through Nginx

    POST /api/auth/oauth/token?grant_type=password&amp;client_id=browser&amp;client_secret=asdf HTTP/1.1
    Host: app1.local.com:8080
    Cache-Control: no-cache
    Postman-Token: b37c7d50-e9e3-2863-59a7-51e0a07c88cf
    Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
    
    ------WebKitFormBoundary7MA4YWxkTrZu0gW
    Content-Disposition: form-data; name="username"
    
    login
    ------WebKitFormBoundary7MA4YWxkTrZu0gW
    Content-Disposition: form-data; name="password"
    
    password
    ------WebKitFormBoundary7MA4YWxkTrZu0gW--
