# Docker Installation
Details about how to use Goma in Docker can be found on the hub.docker.com repo hosting the image: Goma.
We also have some cool examples with [Docker Compose template](https://github.com/jkaninda/goma-gateway/tree/main/examples) with built-in orchestration and scalability.
## 1. Initialize configuration
You can generate the configuration file using `config init --output /etc/goma/config.yml` command.
The default configuration is automatically generated if any configuration file is not provided, and is available at `/etc/goma/goma.yml`
```shell
docker run --rm --name goma-gateway \
-v "${PWD}/config:/etc/goma/" \
jkaninda/goma-gateway config init --output /etc/goma/config.yml
```
### 3. Start server with a custom config
```shell
docker run --rm --name goma-gateway \
-v "${PWD}/config:/etc/goma/" \
-p 8080:8080 \
jkaninda/goma-gateway server --config /config/config.yml
```
### 4. Healthcheck
- Goma Gateway health check: `/health/live`
- Routes health check: `health/routes`
### 5. Simple deployment in docker compose file
```yaml
services:
goma-gateway:
image: jkaninda/goma-gateway
command: server
ports:
- "8080:8080"
- "8443:8443"
volumes:
- ./config:/etc/goma/

## Middlewares
Middleware is a function executed before (or after) the route callback.
This is a great way to add API authentication checks, or to validate that the user has permission to access the route.
With Goma you can create your middleware based on the type you want and apply it on your routes
Goma Gateway supports :
- Authentication middleware
- JWT `client authorization based on the result of a request`
- Basic-Auth
- OAuth
- Rate limiting middleware
- In-Memory client IP based
- Access middleware
### BasicAuth middleware
The BasicAuth middleware grants access to route to authorized users only.
### Configuration Options
You don't need to hash your password (MD5, SHA1, or BCrypt), Goma gateway will handle it.
You need just to provide the username and password
Example of basic-auth middleware
```yaml
middlewares:
# Middleware name
- name: basic-auth
# Middleware type
type: basic
# Paths to apply middleware
paths:
- /user
- /admin
- /account
rule:
username: admin
password: admin
```
### JWT middleware
As BasicAuth, JWT middleware grants also access to route to authorized users only.
It implements client authorization based on the result of a request.
If the request returns a 200 response code, access is allowed.
If it returns 401 or 403, the access is denied with the corresponding error code. Any other response code returned by the request is considered an error.
It depends on an authentication service on the backend.
It works as `ngx_http_auth_request_module` on Nginx
```conf
location /private/ {
auth_request /auth;
...
}
location = /auth {
proxy_pass ...
proxy_pass_request_body off;
proxy_set_header Content-Length "";
proxy_set_header X-Original-URI $request_uri;
}
```
You can also get headers from the authentication request result and inject them into the next request header or params.
In case you want to get headers from the authentication service and inject them into the next request headers.
Set the request variable to the given value after the authorization request completes.
Key is authentication request response header Key. Value is the next Request header Key.
```yaml
headers:
## Key Authentication request header key and value is next request header key
userId: X-Auth-UserId
userCountryId: X-Auth-UserCountryId
```
The second example, is in case you want to get headers from the authentication request and inject them into the next request parameters.
Key is authentication request response header Key. Value is the next Request parameter Key.
See the example below.
```yaml
# Key Authentication request header key and value is next request parameter key
params:
userId: userId
userCountryId: countryId
```
Example of JWT middleware
```yaml
middlewares:
#Enables JWT authorization based on the result of a request and continues the request.
- name: google-auth
# jwt authorization based on the result of backend's response and continue the request when the client is authorized
type: jwt
# Paths to protect
paths:
- /protected-access
- /example-of-jwt
#- /* or wildcard path
rule:
# This is an example URL
url: https://www.googleapis.com/auth/userinfo.email
# Required headers, if not present in the request, the proxy will return 403
requiredHeaders:
- Authorization
#Set the request variable to the given value after the authorization request completes.
#
# Add header to the next request from AuthRequest header, depending on your requirements
# Key is AuthRequest's response header Key, and value is Request's header Key
# In case you want to get headers from the authentication service and inject them into the next request header or parameters,
#Set the request variable to the given value after completing the authorization request.
#
# Add header to the next request from AuthRequest header, depending on your requirements
# Key is AuthRequest's response header Key, and value is next request header Key
# In case you want to get headers from the authentication service and inject them into the next request headers.
headers:
userId: X-Auth-UserId
userCountryId: X-Auth-UserCountryId
# In case you want to get headers from the Authentication service and inject them to the next request params.
params:
userCountryId: countryId
```
### OAuth middleware
Example of Google provider
```yaml
- name: google-oauth
type: oauth
paths:
- /*
rule:
clientId: xxx
clientSecret: xxxx
# oauth provider google, gitlab, github, amazon, facebook, custom
provider: google # facebook, gitlab, github, amazon
redirectUrl: https://example.com/callback/protected
#RedirectPath is the PATH to redirect users after authentication, e.g: /my-protected-path/dashboard
redirectPath: /dashboard
scopes:
- https://www.googleapis.com/auth/userinfo.email
- https://www.googleapis.com/auth/userinfo.profile
state: randomStateString
jwtSecret: your-strong-jwt-secret | It's optional
```
Example of Authentik provider
```yaml
- name: oauth-authentik
type: oauth
paths:
- /protected
- /example-of-oauth
rule:
clientId: xxx
clientSecret: xxx
# oauth provider google, gitlab, github, amazon, facebook, custom
provider: custom
endpoint:
authUrl: https://authentik.example.com/application/o/authorize/
tokenUrl: https://authentik.example.com/application/o/token/
userInfoUrl: https://authentik.example.com/application/o/userinfo/
redirectUrl: https://example.com/callback
#RedirectPath is the PATH to redirect users after authentication, e.g: /my-protected-path/dashboard
redirectPath: ''
#CookiePath e.g.: /my-protected-path or / || by default is applied on a route path
cookiePath: "/"
scopes:
- email
- openid
state: randomStateString
jwtSecret: your-strong-jwt-secret | It's optional
```
### Access middleware
Access middleware prevents access to a route or specific route path.
Example of access middleware
```yaml
# The server will return 403
- name: api-forbidden-paths
type: access
## prevents access paths
paths:
- /swagger-ui/*
- /v2/swagger-ui/*
- /api-docs/*
- /internal/*
- /actuator/*
```
### RateLimit middleware
The RateLimit middleware ensures that services will receive a fair amount of requests, and allows one to define what fair is.
Example of rateLimit middleware
```yaml
```
### Apply middleware on the route
```yaml
##### Define routes
routes:
- name: Basic auth
path: /protected
rewrite: /
destination: 'https://example.com'
methods: [POST, PUT, GET]
healthCheck:
cors: {}
middlewares:
# Name of middleware
- basic-auth
- access
```

```shell
docker run --rm --name goma-gateway \
-v "${PWD}/config:/etc/goma/" \
jkaninda/goma-gateway config init --output /etc/goma/config.yml
```
### 3. Start server with a custom config
```shell
docker run --rm --name goma-gateway \
-v "${PWD}/config:/etc/goma/" \
