Build your REST API's in minutes.

Welcome to the workshop 

Install.

Backend

Docker: Pull the node images for the backend.

docker pull balanus/loopback

Docker: run a local development docker container for loopback

docker run -d -it -v <path to your folder>:/usr/src/app -p 3000:3000 --name="api" balanus/loopback bash

Example

docker run -d -it -v /home/std-user01/Projects/workshop/session1_loopback_api_demo/:/usr/src/app -p 3000:3000 --name="api" balanus/loopback bash

Now connect to the docker container, which provides loopback-cli

docker exec -it api bash

Now you are inside the container, you will be able to generate loopback application.

Check your installation is correct or not.

Run docker exec and go inside the container, and make sure you are having the same version of the following.

root@abd70e13f28c:/# node --version
v9.8.0
root@abd70e13f28c:/# npm --version
5.7.1
root@abd70e13f28c:/# lb --version
4.1.0 ([email protected] [email protected])

Frontend: Angular 5

FYI- Hint: This is based on alpine images.

Docker: Pull the ng5/Angular-5 images for the frontend.

docker pull balanus/ng5

Docker: run a local development docker container for angular5

docker run -d -it -v <path to your folder>:/app -p 4200:4200 --name="web" balanus/ng5 bash

Example

docker run -d -it -v /home/std-user01/Projects/workshop/session1_loopback_api_demo/:/app -p 4200:4200 --name="web" balanus/ng5 sh

Now connect to the docker container, which provides angular-cli /ng

docker exec -it web sh

Now you are inside the container, you will be able to generate angular5/ng application.

Check your installation is correct or not.

Run docker exec and go inside the container, and make sure you are having the same version of the following.

/ # node --version
v8.9.4
/ # npm --version
5.7.1
/ # ng --version

Lets prepare the database container for our APP

To link to mysql container.

docker run --name some-app --link some-mysql:mysql -d application-that-uses-mysql

To run a mysql container:

docker run --name mysqldb -e MYSQL_ROOT_PASSWORD=<password> -e MYSQL_DATABASE=<dbname> -e MYSQL_USER=<username> -e MYSQL_PASSWORD=<password> -p 3306:3306 -v <data folder to map>:/var/lib/mysql -d mysql:latest 

For example we can use this configuration for our APP.

Run the following to get a mysqldb container with the following config

1. MYSQL_DATABASE = sampledb
2. MYSQL_ROOT_PASSWORD = root
3. MYSQL_USER = appuser
4. MYSQL_PASSWORD = supersecret
5. volume /home/std-user01/Projects/workshop/session1_loopback_api_demo/data will be mounted as data folder /var/lib/mysql

docker run --name mysqldb -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=sampledb -e MYSQL_USER=appuser -e MYSQL_PASSWORD=supersecret -p 6606:3306 -v /home/std-user01/Projects/workshop/session1_loopback_api_demo/data:/var/lib/mysql -d mysql:latest 

Now We have expose our db container to the backend (loopback) container.

You can achieve this by two ways.

1. Linking both backend container with mysqldb container.
2. Launching both containers in same network

For now, lets launch both db container and backend container under a same network namespace.

For that we need to stop these running containers

docker stop api mysqldb
docker rm api mysqldb

Create a docker network to connect the two containers.

docker network create backend

Now start the two containers (api, mysqldb) on the same network that we created above.

docker run --name mysqldb -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=sampledb -e MYSQL_USER=appuser -e MYSQL_PASSWORD=supersecret -p 6606:3306 -v /home/std-user01/Projects/workshop/session1_loopback_api_demo/data:/var/lib/mysql --network=backend -d mysql:latest 

docker run -d -it -v /home/std-user01/Projects/workshop/session1_loopback_api_demo/:/usr/src/app -p 3000:3000 --name="api" --network=backend balanus/loopback bash

Finally to check, if you run this

docker ps

You should see the following,

std-user01@stduser01-Latitude-E5470:~/Projects/workshop/session1_loopback_api_demo$ docker ps
