Deploy HowTo

1. Start docker daemon on Mac OS

   launch boot2docker app (std password - tcuser)

2. Prepare environment to use docker

   export DOCKER_HOST=tcp://192.168.59.103:2376
   export DOCKER_CERT_PATH=/Users/kojuhovskiy/.boot2docker/certs/boot2docker-vm
   export DOCKER_TLS_VERIFY=1
   

3. Build jar file & try server locally:

   sbt assembly
   java -jar docker-spray-[...].jar
   

4. Build new docker image for user gothug called spray-docker

   docker build -t="gothug/spray-docker" .
   

5. Run image locally (optional) (correctly substitute image id, last param in docker run)

   docker run -d -p 9090:8080 gothug/spray-docker
   boot2docker ip
   curl "http://192.168.59.103:9090/hello"
   

6. Push docker image to docker hub

   docker push gothug/spray-docker
   

7. Pull & run image on Digital Ocean instance (correctly substitute image id, last param in docker run)

   ssh -i ~/.ssh/id_rsa_digitalocean root@188.166.11.149
   docker pull gothug/spray-docker
   docker run -d -p 9090:8080 82a7df479a58
   

8. Send a test request to the deployed server

   curl "http://188.166.11.149:9090/hello"
   

Deploy locally from digital ocean server (the fastest way)

0. Get to server

   ssh -i ~/.ssh/id_rsa_digitalocean root@188.166.11.149

1. Build && start postgresql container

   git clone https://github.com/gothug/docker-configs cd docker-configs/postgresql git pull; docker build -t="gothug/postgresql" . docker run -d -p 5432:5432 --name postgres gothug/postgresql

   cd ~/movie-geek JAVA_OPTS="-Xms250m -Xmx384m" sbt "run-main mvgk.db.DBManager drop create"

2. Build && start movie service

   git clone https://github.com/gothug/docker-spray-example.git cd docker-spray-example JAVA_OPTS="-Xms250m -Xmx384m" sbt assembly docker build -t="gothug/spray-docker" . docker run -d -p 9090:8080 --link postgres:pgsql gothug/spray-docker

Test requests

1. General

   curl "http://localhost:8080/request" curl -v -X POST http://localhost:8080/request -H "Content-Type: application/json" -d '{"name": "Bob", "firstName": "Parr", "age": 32}'

   curl -X POST http://localhost:8080/watchlist/imdb -H "Content-Type: application/json" -d '{"link": "http://www.quickproxy.co.uk/index.php?q=aHR0cDovL3d3dy5pbWRiLmNvbS91c2VyL3VyOTExMjg3OC93YXRjaGxpc3Q%2FcmVmXz13dF9udl93bF9hbGxfMA%3D%3D&hl=2ed"}'

2. User service

   curl http://localhost:8080/user curl -X POST http://localhost:8080/user -H "Content-Type: application/json" -d '{"email": "kojuhovskiy@gmail.com", "subscribed": false}'

Useful tips

1. Extract a particular file from jar

   jar xvf ~/github/docker-spray-example/target/scala-2.11/docker-spray-example-assembly-1.0.jar reference.conf

2. See memory usage per process:

   ps -C -O rss

3. Run java on a box with 512Mb of memory:

   JAVA_OPTS="-Xms250m -Xmx384m" sbt assembly

Useful docker tips

1. Run bash inside a docker container:

   sudo docker exec -it bash

   sudo docker exec -it docker ps -a | tail -n1 | cut -d' ' -f1 bash

2. Get into an image:

   docker run -t -i gothug/postgresql /bin/bash

3. Delete all docker images:

   docker images | awk '{print $3}' | xargs docker rmi

Database

0. Setup

   CREATE USER geek WITH SUPERUSER PASSWORD 'q1'; CREATE DATABASE geek WITH OWNER = geek;

1. Db access

   pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start psql -d moviedb -U geek

2. Db create

   sbt "run-main mvgk.db.DBManager create"

3. Db drop create

   sbt "run-main mvgk.db.DBManager drop create"

4. Db update

   sbt "run-main mvgk.db.DBManager update"
