========
![A video showing how Eclair works]
Simple ssh helper for Amazon EC2
```bash
gem install ecl
```
### Requirements
- tmux > 2.0
- Properly configured `~/.aws/credentials`
### Usage
```console
$ ecl
```
First execution will create `~/.ecl/config.rb` file. Edit this file and run again.
Configurations
--------
### aws_region
AWS region to connect.
```ruby
config.aws_region = "ap-northeast-1"
```
### columns
Max number of columns displayed in eclair.
```ruby
config.columns = 4
```
### ssh_username
Function to find username from image. Returns username of given image. Uses
image data from [EC2::Client#describe_images] API call.
```ruby
config.ssh_username = lambda do |image|
case image.name
when /ubuntu/
"ubuntu"
else
"ec2-user"
end
end
```
### group_by
Function to find group name from instance. Returns group name from instance
data. Uses instance data from [EC2::Client#describe_instances] API call.
You can group instances by security groups with this config:
```ruby
config.group_by = lambda do |instance|
if instance.security_groups.first
instance.security_groups.first.group_name
else
"no_group"
end
end
```
Grouping by instance name is also possible:
```ruby
config.group_by = lambda do |instance|
case instance.name
when /^production/
"production servers"
when /^test/
"test servers"
end
end
```
You can disable grouping by assigning nil:
```ruby
config.group_by = nil
```
### ssh_ports
Port numbers to try ssh.
```ruby
config.ssh_ports = [1234, 22]
```
### ssh_options
Extra options passed to ssh.
```ruby
config.ssh_options = "-o ConnectTimeout=1 -o StrictHostKeyChecking=no"
```
### ssh_hostname
Hostname to use in ssh. Choose from `:public_dns_name`, `:public_ip_address`,
`:private_dns_name`, `:private_ip_address`
```ruby
config.ssh_hostname = :public_ip_address
```
### ssh_keys
Hash of EC2 keypair name => key_path in local. If your key has been already
registered in ssh-agent, you don't have to configure this.
```ruby
config.ssh_keys = {
"keypair1" => "/path/to/key1",
"keypair2" => "/path/to/key2",
}
```
### use_vpc_id_env (Experimental)
_This Feature is experimental and subject to change in future versions_
Boolean variable. If true use VPC_ID Environment variable for filtering EC2 instances.
```ruby
config.use_vpc_id_env = true
```
Example VPC_ID variable:
```
VPC_ID=vpc-12345678901234567
```
Install from Source
