Updating play framework secret key for your application

Updating the application secret in application.conf

Play also provides a convenient utility for updating the secret in application.conf, should you want to have a particular secret configured for development or test servers. This is often useful when you have encrypted data using the application secret, and you want to ensure that the same secret is used every time the application is run in dev mode.

To update the secret in application.conf, run playUpdateSecret in the Play console:

[my-first-app] $ playUpdateSecret
[info] Generated new secret: B4FvQWnTp718vr6AHyvdGlrHBGNcvuM4y3jUeRCgXxIwBZIbt
[info] Updating application secret in /Users/jroper/tmp/my-first-app/conf/application.conf
[info] Replacing old application secret: play.crypto.secret="changeme"

Play deployment

1)binary distribution
 activator dist
copy target/universal/*.zip to production server ex:/home/ikhbla/workspace

login to production server
cd /home/ikbhal/workspace
unzip
https://www.playframework.com/documentation/2.4.x/Production
Dapplication.secret=abcdefghijk.
dist
target/universal
unzip my-first-app-1.0.zip
$ my-first-app-1.0/bin/my-first-app -Dplay.crypto.secret=abcdefghijk

my-first-app-1.0/bin/my-first-app -Dconfig.file=/full/path/to/conf/application-prod.conf

2)Running with source code in production

Running a production server in place

In some circumstances, you may not want to create a full distribution, you may in fact want to run your application from your project’s source directory. This requires an sbt or activator installation on the server, and can be done using the stage task.

$ activator clean stage

2.1)Running as test instance on production

Running a test instance

Play provides a convenient utility for running a test application in prod mode.

This is not intended for production usage.

To run an application in prod mode, run testProd:

[my-first-app] $ testProd

Play generate secret key

[my-first-app] $ playGenerateSecret
[info] Generated new secret: QCYtAnfkaZiwrNwnxIlR6CTfG3gf90Latabg5241ABR5W1uDFNIkn
[success] Total time: 0 s, completed 28/03/2014 2:26:09 PM

AWS ec2 selection decision for Play Framework 2.4

use nginx as front load balancer for port forwarding from 80 to 9000

old reference might not work exactly

SCRIPT: /al-start.sh

chmod +x start
nohup ./start -server -Dconfig.resource=application-prod.conf -Dhttp.port=9000 &

A few notes about this script:

I created this script so I don’t have to edit the Play start script.
It uses a Play configuration file named application-prod.conf. That file just needs to be on the classpath, so having it in the Play application conf folder is all you need.
It runs the server on port 9000. You don’t need to specify that on the command line, but I have a bad memory, so if I want to change this later, it’s easiest to specify it now.


Another note about the production environment: Port 80 on the kbhr.co website is served by Nginx, and it does a proxy to serve the Play application.

HOW DOCKER WORKS

Docker is a client-server application. The Docker server is a daemon that does all the heavy lifting: building and downloading images, starting and stopping containers, and the like. It exposes a REST API for remote management.

The Docker client is a command line program that communicates with the Docker server using the REST API. You will interact with Docker by using the client to send commands to the server.

The machine running the Docker server is called the Docker host. The host can be any machine—your laptop, a server in the Cloud™, etc—but, because Docker uses features only available to Linux, that machine must be running Linux (more specifically, the Linux kernel).

We’ll run the Docker client natively on OS X, but the Docker server will run inside our boot2docker VM. This also means boot2docker, not OS X, is the Docker host.

old tutorial

----

Step 3: Initialize and start boot2docker

First, we need to initialize boot2docker (we only have to do this once):

> boot2docker init
2014/08/21 13:49:33 Downloading boot2docker ISO image...
    [ ... ]
2014/08/21 13:49:50 Done. Type `boot2docker up` to start the VM.

Next, we can start up the VM. Do like it says:

> boot2docker up
2014/08/21 13:51:29 Waiting for VM to be started...
.......
2014/08/21 13:51:50 Started.
2014/08/21 13:51:51   Trying to get IP one more time
2014/08/21 13:51:51 To connect the Docker client to the Docker daemon, please set:
2014/08/21 13:51:51     export DOCKER_HOST=tcp://192.168.59.103:2375

Step 4: Set the DOCKER_HOST environment variable

The Docker client assumes the Docker host is the current machine. We need to tell it to use our boot2docker VM by setting the DOCKER_HOST environment variable:

> export DOCKER_HOST=tcp://192.168.59.103:2375

docker volume practice

docker run -d -P --name web -v /webapp training/webapp python app.py
docker run -d -P --name web -v /opt/webapp:ro training/webapp python app.py
docker inspect web
docker run -d -P --name web -v /src/webapp:/opt/webapp training/webapp python app.py

docker rm nostalgic_morse
docker run -t -i ubuntu:14.04 /bin/bash

docker images
docker pull centos
docker pull training/sinatra

docker run -t -i training/sinatra /bin/bash

Dockerfile
use a Dockerfile to specify instructions to create an image.
docker commit -m "Added json gem" -a "Kate Smith" \ 0b2616b0e5a8 ouruser/sinatra:v2

$ mkdir sinatra 
$ cd sinatra 
$ touch Dockerfile
docker build

Dockerfile
FROM ubuntu:14.04 
MAINTAINER Kate Smith  
RUN apt-get update && apt-get install -y ruby ruby-dev 
RUN gem install sinatra

docker tag 5db5f8471261 ouruser/sinatra:devel
docker push ouruser/sinatra
docker rmi training/sinatra

docker run -d --name db training/postgres
docker rm -f web
docker run -d -P --name web --link db:db training/webapp python app.py
https://docs.docker.com/userguide/dockervolumes/

docker container practice

ocker run -d -p 80:5000 training/webapp python app.py

This would map port 5000 inside our container to port 80 on our local host. You might be asking about now: why wouldn’t we just want to always use 1:1 port mappings in Docker containers rather than mapping to high ports? Well 1:1 mappings have the constraint of only being able to map one of each port on your local host. Let’s say you want to test two Python applications: both bound to port 5000 inside their own containers. Without Docker’s port mapping you could only access one at a time on the Docker host.

Note: If you have used the boot2docker virtual machine on OS X, Windows or Linux, you’ll need to get the IP of the virtual host instead of using localhost. You can do this by running the following outside of the boot2docker shell (i.e., from your comment line or terminal application).

$ boot2docker ip
The VM's Host only interface IP address is: 192.168.59.103

In this case you’d browse to http://192.168.59.103:49155 for the above example.
