spring-boot-multitenant

Multi tenancy example using spring boot and the Hibernate SCHEMA strategy.

Getting started

Pre-requisites

• Java 1.8
• Docker
• Docker-compose

Installation (debian base)

Install Docker

apt-get install apparmor lxc cgroup-lite
wget -qO- https://get.docker.com/ | sh
sudo usermod -aG docker YourUserNameHere
sudo service docker restart

Install Docker-compose (1.6+)

MAKE SURE YOU HAVE AN UP TO DATE VERSION OF DOCKER COMPOSE

To check the version:

docker-compose --version

To install the 1.6.0:

sudo su
curl -L https://github.com/docker/compose/releases/download/1.6.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
exit

To run

docker-compose up

To run docker mysql while running app locally

docker-compose up mysql
./gradlew bootRun

Usage

Prime the database (only needs to be done once)

docker-compose up mysql
mysql -u root   -p1234   -h 127.0.0.1 -e "GRANT ALL ON *.* TO 'myuser'@'%'; FLUSH PRIVILEGES;"
mysql -u myuser -pmypass -h 127.0.0.1 < db_migration.sql

At this point there should be two identical databases tenant_a and tenant_b with privileges such that the myuser account can access both

Start the app

./gradlew clean build buildDocker
docker-compose up api

API interactions

curl -H "X-TenantID:tenant_a" localhost:8080/person/1
