## Installation
|
|
|
|
Add this line to your application's Gemfile:
|
|
|
|
```ruby
|
|
gem 'fog-aws'
|
|
```
|
|
|
|
And then execute:
|
|
|
|
$ bundle
|
|
|
|
Or install it yourself as:
|
|
|
|
$ gem install fog-aws
|
|
|
|
## Usage
|
|
|
|
Before you can use fog-aws, you must require it in your application:
|
|
|
|
```ruby
|
|
require 'fog/aws'
|
|
```
|
|
|
|
Since it's a bad practice to have your credentials in source code, you should load them from default fog configuration file: ```~/.fog```. This file could look like this:
|
|
|
|
```
|
|
default:
|
|
aws_access_key_id: <YOUR_ACCESS_KEY_ID>
|
|
aws_secret_access_key: <YOUR_SECRET_ACCESS_KEY>
|
|
```
|
|
|
|
### EC2
|
|
|
|
#### Connecting to the EC2 Service:
|
|
|
|
```ruby
|
|
ec2 = Fog::Compute.new :provider => 'AWS', :region => 'us-west-2'
|
|
```
|
|
|
|
You can review all the requests available with this service using ```#requests``` method:
|
|
|
|
```ruby
|
|
ec2.requests # => [:allocate_address, :assign_private_ip_addresses, :associate_address, ...]
|
|
```
|
|
|
|
#### Launch an EC2 on-demand instance:
|
|
|
|
```ruby
|
|
response = ec2.run_instances(
|
|
"ami-23ebb513",
|
|
1,
|
|
1,
|
|
"InstanceType" => "t1.micro",
|
|
"SecurityGroup" => "ssh",
|
|
"KeyName" => "miguel"
|
|
)
|
|
instance_id = response.body["instancesSet"].first["instanceId"] # => "i-02db5af4"
|
|
instance = ec2.servers.get(instance_id)
|
|
instance.wait_for { ready? }
|
|
puts instance.public_ip_address # => "356.300.501.20"
|
|
```
|
|
|
|
#### Terminate an EC2 instance:
|
|
|
|
```ruby
|
|
instance = ec2.servers.get("i-02db5af4")
|
|
instance.destroy
|
|
```
|
|
|
|
`Fog::AWS` is more than EC2 since it supports many services provided by AWS. The best way to learn and to know about how many services are supported is to take a look at the source code. To review the tests directory and to play with the library in ```bin/console``` can be very helpful resources as well.
|
|
|
|
### S3
|
|
|
|
#### Connecting to the S3 Service:
|
|
|
|
```ruby
|
|
s3 = Fog::Storage.new(provider: 'AWS', region: 'eu-central-1')
|
|
```
|
|
|
|
#### Creating a file:
|
|
|
|
```ruby
|
|
directory = s3.directories.new(key: 'gaudi-portal-dev')
|
|
file = directory.files.create(key: 'user/1/Gemfile', body: File.open('Gemfile'), tags: 'Org-Id=1&Service-Name=My-Service')
|
|
```
|
|
|
|
#### Listing files:
|
|
|
|
```ruby
|
|
directory = s3.directories.get('gaudi-portal-dev', prefix: 'user/1/')
|
|
directory.files
|
|
```
|
|
|
|
#### Generating a URL for a file:
|
|
|
|
```ruby
|
|
directory.files.new(key: 'user/1/Gemfile').url(Time.now + 60)
|
|
```
|
|
|
|
#### Copying a file
|
|
|
|
```ruby
|
|
directory = s3.directories.new(key: 'gaudi-portal-dev')
|
|
file = directory.files.get('user/1/Gemfile')
|
|
file.copy("target-bucket", "user/2/Gemfile.copy")
|
|
```
|
|
|
|
To speed transfers of large files, the `concurrency` option can be used
|
|
to spawn multiple threads. Note that the file must be at least 5 MB for
|
|
multipart uploads to work. For example:
|
|
|
|
```ruby
|
|
directory = s3.directories.new(key: 'gaudi-portal-dev')
|
|
file = directory.files.get('user/1/Gemfile')
|
|
file.multipart_chunk_size = 10 * 1024 * 1024
|
|
file.concurrency = 10
|
|
file.copy("target-bucket", "user/2/Gemfile.copy")
|
|
```
