## Configuration files

### Docker daemon

Edit `config/initializers/docker.rb`

### Nginx server

Edit `config/initializers/nginx.rb`

### .env file

```
cp .env.example .env

# settings for SMTP/Token
vi .env
source .env
```

## Start server

```
RAILS_ENV=production rake assets:precompile
RAILS_ENV=production rake db:migrate
RAILS_ENV=production rails s -b 0.0.0.0
```

## Create an account and login

## Create Nginx Configuration's template

Login and go to `/templates/new` to create template file. In the `nginx.conf` file, you kan use placeholder `{{upstream}}`, this will be substituted by running containers info.

For example:

```
{{upstream}}

server {

location /{
add_header u $u;
proxy_pass http://backend_$u;
}
```

## Pull an image

In `http://localhost:3000/iamges` page, pull an image

## Deploy an container

In `http://localhost:3000/containers` page, create a new conatiner.

## Generate Nginx config files and reload

If you have to containers are running:

```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0e738babaf33 busybox "httpd -p 8080 -f" About an hour ago Up About an hour 0.0.0.0:32770->8080/tcp app-v2
4348bed6e1c9 busybox "httpd -p 8080 -f" About an hour ago Up About an hour 0.0.0.0:32769->8080/tcp app-v1
```

Click `Create Config File` button will generate somethins like this:

```
upstream backend_app-v2
{
server localhost:32770;
}

upstream backend_app-v1
{
server localhost:32769;
}

map $http_v, $u{
~app-v2 app-v2;
~app-v1 app-v1;
default app-v1;
}

server {

location /{
add_header u $u;
proxy_pass http://backend_$u;
}
```

# Limitations and restrictions

- Can't mount local volumes
- Will expose all ports defined in `Dockerfile`
- You can specify only container name and `CMD` params when deploy new containers.
- Can process only one Nginx config file, normally it should be `/etc/nginx/nginx.conf`
