# Portl Widget Microservice

For security, the server listens only on localhost (127.0.0.1) and requires HTTP Basic 
Authentication. Because no network traffic is accepted or processed (packets never leave 
the host). Currently, the server uses a self signed certificate - details below.

## Build Prerequisites

1. Java version 1.8
2. Maven version 3
3. Connectivity to AT&T Maven Central

## Run Prerequisites

1. Java version 1.8
2. A Mysql database using the same database as the Portal

## Build and Package

Use maven to build and package the microservice into a jar using this command:

	mvn clean package

## Configuring

All configuration parameters are entered in a file called application.properties.  A version with default values can be found in the top level of this project. 

Details about the database are configured in this file. The default entries for the database configuration are shown here:

	spring.datasource.url=jdbc:mariadb:failover://{db_host:db_port/{portal_db}
	spring.datasource.username={username}
	spring.datasource.password=ENC({encrypted_password})

The HTTP server's username and password are configured in this file.  Only one username/password is used to secure the REST endpoint. The default entries for the server are shown here:

	security.user.name={basic_auth_username}
	security.user.password=ENC({encrypted_basic_auth_password})

When you package the application into a jar file and launch the microservice using that jar, the configuration file must be in the current working directory where you launch the service.

## Generating Encrypted Passwords

Use the following command to generate an encrypted password for the database and the
micro service.  The entire command must be entered on one line; the command shown 
below uses backslashes to break lines for readability:

	java -cp ~/.m2/repository/org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar \
		org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI \
		algorithm=PBEWithMD5AndDES \
		input='YourPasswordHere' \
		password='EncryptionKey'

Note, 'YourPasswordHere' is the actual database password, as supplied in the 'password' 
parameter.  The value 'EncryptionKey' is used to encrypt the input, and must be supplied
at run time in one of two ways:

* On the command line with a JVM argument "-Djasypt.encryptor.password".  Here's an example
of using maven with the Spring-Boot goal:

	mvn -Djasypt.encryptor.password=EncryptionKey spring-boot:run
	
Here's an example of using java and the jar file:

	java -jar dbc-microservice.jar -Djasypt.encryptor.password=EncryptionKey

* In the application.properties file using the key jasypt.encryptor.password.  For example:

	jasypt.encryptor.password=EncryptionKey

## Development Launch

Check the configuration properties in file src/main/resources/application.properties.  Then launch the microservice for development and testing like this:

	mvn clean spring-boot:run

## Production Launch

Ensure a valid configuration is present in file application.properties in the current working directory.  Then launch the microservice for production like this:

	widget-service.sh start

## Supported Methods

This micro service supports the following methods.  All can be accessed with a web browser
or a REST client such as Postman. 

## Generating Encrypted Passwords

Use the following command to generate an encrypted password for the database and the
micro service.  The entire command must be entered on one line; the command shown 
below uses backslashes to break lines for readability:

	java -cp ~/.m2/repository/org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar \
		org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI \
		algorithm=PBEWithMD5AndDES \
		input='YourPasswordHere' \
		password='EncryptionKey'

Note, 'YourPasswordHere' is the actual database password, as supplied in the 'password' 
parameter.  The value 'EncryptionKey' is used to encrypt the input, and must be supplied
at run time in one of two ways:

* On the command line with a JVM argument "-Djasypt.encryptor.password".  Here's an example
of using maven with the Spring-Boot goal:

	mvn -Djasypt.encryptor.password=EncryptionKey spring-boot:run
	
Here's an example of using java and the jar file:

	java -jar dbc-microservice.jar -Djasypt.encryptor.password=EncryptionKey

* In the application.properties file using the key jasypt.encryptor.password.  For example:

	jasypt.encryptor.password=EncryptionKey

## Certificate

### Create self signed certificate

1. Create a self signed certificate for the microservice
keytool -genkey -alias widget-microservice -storetype PKCS12 -keyalg RSA -keystore widget-keystore.p12

### Import into client's trust store

1. Export certificate from microservice's keystore - default password is 'microservice'
keytool -exportcert -keystore widget-keystore.p12 -alias widget-microservice -file widget-cert.cer

2. Import the exported certificate of microservice from step 1 and import it into Portal JRE's cacerts file. The location of this file is %JRE%/lib/secuirty/cacerts.

keytool -import -trustcacerts -keystore "C:\Program Files\Java\jre1.8.0_91\lib\security\cacerts" -noprompt -alias widget-microservice -file widget-cert.cer

OR 
;
keytool -import -trustcacerts -keystore /usr/local/add-on/jdk1.8.0_60/jre/lib/security/ -noprompt -alias widget-microservice -file widget-cert.cer

### Runing on http (not https)

If the intent is to run this microservice without https i.e run on plain http, comment out (put a leading #) infront of all properties in 'Certificate Properties' section of application.properties - these properties are

server.ssl.key-store=classpath:widget-keystore.p12
server.ssl.key-store-password=ENC(DiIYnAMab4u7rEW2yKhF9zBL00uU55q8)
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=widget-microservice

## Running service in docker

a). Build docker image: mvn docker:build
b). Run the service in docker: docker run -p <port>:<port-in> -t <image-name> 
c). Check running docker containers: docker ps

## Migration Instruction  
1. Due to changes in the existing tables, the user will have to remove all the existing widgets in 1702 release 
2. Re-upload the latest version of widgets under dashboard-widgets folder
