tcp update aws guide

## bioapps TCP

### Aws location:

* Monash eSol AWS account [https://login.monash.edu/adfs/ls/idpinitiatedsignon](https://login.monash.edu/adfs/ls/idpinitiatedsignon)
* RES-SPT-Automation/Steve.Androulakis@monash.edu
* Oregon availability zone
* Elastic Beanstalk controlled

### Elastic beanstalk scaling settings

**tested with AWS and works**

* Min instances: 2
* Max instances: 10

Scaling trigger:
* Avg latency > 1 second

### Application configuration

Docker image config for elastic beanstalk

```
{
  "AWSEBDockerrunVersion": "1",
  "Image": {
    "Name": "550842539797.dkr.ecr.us-west-2.amazonaws.com/tcp_shiny:latest",
    "Update": "true"
  },
  "Ports": [
    {
      "ContainerPort": "80"
    }
  ],
  "Logging": "/var/log/nginx"
}
```

### Application Update

Grab this docker image and run it with 

`docker run -it  -p 5909:80 -p 5910:3838 550842539797.dkr.ecr.us-west-2.amazonaws.com/tcp_shiny:latest bash`

Edit the TCP application under `/srv/shiny/`

Make an image out of the existing container:

*Note: (ctrl + p, ctrl q to get out of interactive)*

`sudo docker commit <imageID> shiny_tcp_1.x`

Returns <newimageID>

App needs to auto run a process for AWS docker to work, so change the image.

`sudo docker commit --change "CMD /tmp/run.sh" <newimageID> tcp_shiny`

### Push Update

Summary: Commit your new image to AWS docker image catalog (private) and then upload a new elastic beanstalk config referring to it.

Tag the image for amazon by their rules (the long number in the address is our account):

`docker tag -f tcp_shiny 550842539797.dkr.ecr.us-west-2.amazonaws.com/tcp_shiny:latest`

get login first (requires `aws configure` to be run first and the amazon cli tools)

`aws ecr get-login`

For docker cli access to the AWS private docker image store.

`docker push 550842539797.dkr.ecr.us-west-2.amazonaws.com/tcp_shiny:latest`

Your image is now pushed.

Now go to AWS in the web and upload a new elastic beanstalk configuration (create a .json file out of the code above). This will trigger updates.
