  1 | # SSH Auto Connector for EC2 Instance
  2 | 
  3 | Simple commands which connects to AWS EC2 Instances! 
  4 | 
  5 | You don't need to check your changed EC2 instance IP anymore. Just use **'ec2-connect'**
  6 |

  9 | [ec2-ssh-autoconnect](https://github.com/alicek106/ec2-ssh-autoconnect) 의 속도를 개선한 Go 구현 버전입니다. 
 10 | 
 11 | # 1. Features
 12 | 
 13 | Features that this script provide is..
 14 | 
 15 | - Start and stop a EC2 instance
 16 | - Start and stop multiple EC2 instances as a group
 17 | - **Connect SSH to a EC2 instance automatically**
 18 | - List all EC2 instances
 19 | 
 20 | # 2. Install
 21 | 
 22 | ## 2.1 Install binary
 23 | 
 24 | Download release binary. Currently, MacOS is only supported.
 25 | 
 26 | ```
 27 | $ wget https://github.com/alicek106/go-ec2-ssh-autoconnect/releases/download/v0.7/ec2-connect-darwin && \
 28 | chmod +x ec2-connect-darwin && \
 29 | mv ec2-connect-darwin /usr/local/bin/ec2-connect
 30 | ```
 31 | 
 32 | ## 2.2 Create configuration file
 33 | 
 34 | Create configuration file as **/etc/ec2_connect_config.yaml** like below.
 35 | 
 36 | ```yaml
 37 | version: v1
 38 | spec:
 39 |   region: "ap-northeast-2"
 40 | 
 41 |   # .spec.credentials is Optional. Instead you can define keys in ~/.aws/credentials
 42 |   credentials: 
 43 |     accessKey: "... :D"
 44 |     secretKey: "... :D"
 45 | 
 46 |   privateKeys:
 47 |   - name: "default" # You should define default key
 48 |     path: "/Users/alicek106/dev/keys/DockerEngineTestInstance.pem"
 49 |   - name: "customKey1" # Optional. you can use this key as alternative
 50 |     path: "/Users/alicek106/dev/keys/VaultAdminKey.pem"
 51 | 
 52 |   instanceGroups:
 53 |   - name: "kubeadm_part"
 54 |     instances: ["kubeadm_master", "kubeadm_worker0"]
 55 |   - name: "kubeadm"
 56 |     instances: ["kubeadm_master", "kubeadm_worker0", "kubeadm_worker1", "kubeadm_worker2"]
 57 |   - name: "consul"
 58 |     instances: ["consul-1", "consul-2", "consul-3"]
 59 |   - name: "vault"
 60 |     instances: ["vault-1-active", "vault-2-standby"]
 61 | ```
 62 | 
 63 | Configuration file consists of four part.
 64 | 
 65 | - **region** : AWS region to use. Instances of only selected region are shown and managed in ec2-connect.
 66 | - **spec.credentails.accessKey and secretKey** : Optional. AWS credentials to use. You can define in ~/.aws/credential as a static credential. Or you can also use assume role from ~/.aws/config (by source_profile and role_arn) to ~/.aws/credentials by shared config.
 67 | - **spec.privateKeys** : Default SSH private key when using **ec2-connect connect** for a EC2 instance. By default, privateKey named "default" will be used, but you can define another SSH private key to connect SSH. It is used by **--key** parameter in command
 68 | - **spec.instanceGroups** : It defines group for starting and stoping multiple EC2 instances. Above example defined 'kubeadm_part' group, so if you use command **ec2-connect group start kubeadm_part**, it will start two instances (kubeadm-worker, kubeadm-worker0).
 69 | 
 70 | 
 71 | ## 2.3 Setting AWS credential
 72 | 
 73 | AWS credentials priority is like below.
 74 | 
 75 | 1. Define credentials in bash environment values: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY  (High Priority)
 76 | 2. Define credentials in /etc/ec2_connect_config.yaml (Medium Priority)
 77 | 3. Define credentials in ~/.aws/credentials (Low Priority)
 78 | 
 79 | FYI, I'm using third way (~/.aws/credentials) :D
 80 | 
 81 | # 3. How to use (Easy!)
 82 | 
 83 | 1. Check EC2 instance list using **ec2-connect list**
 84 | 
 85 |    ```
 86 |    $ ec2-connect list
 87 |    2019/08/11 22:26:08 Cannot found credential in environment variable.
 88 |    2019/08/11 22:26:08 Found credential in configuration file.
 89 |    2019/08/11 22:26:09 Succeed to validate AWS credential.
 90 |    Instance ID		Instance Name		IP Address	Status
 91 |    i-04f9e3da95a25e939	kubeadm-master		Unknown		stopped
 92 |    i-0c35c716a6442a72e	kubeadm-worker0		Unknown		stopped
 93 |    i-0ef65f12957a67559	kubeadm-worker2		Unknown		stopped
 94 |    i-0c4bb55ba07c9edbf	kubeadm-worker1		Unknown		stopped
 95 |    i-0994dac6654fd59e1	Test			13.209.67.72	running
 96 |    ```
 97 | 
 98 | 2. Start EC2 instance using **ec2-connect start**
 99 |    ```
100 |    $ ec2-connect start Test
101 |    2019/08/11 22:26:22 Cannot found credential in environment variable.
102 |    2019/08/11 22:26:22 Found credential in configuration file.
103 |    2019/08/11 22:26:22 Succeed to validate AWS credential.
104 |    2019/08/11 22:26:23 Starting EC2 instance : Test (instance ID: i-0994dac6654fd59e1)
105 |    2019/08/11 22:26:23 Succeed to start EC2 instances.
106 |    ```
107 | 3. Connect to EC2 instance by **ec2-connect connect [EC2 instance name]**. This command uses private key defined in /etc/ec2_connect_config.yaml (spec.privateKeys)
108 | 
109 |    ```
110 |    $ ec2-connect connect Test
111 |    2019/08/11 22:26:54 Cannot found credential in environment variable.
112 |    2019/08/11 22:26:54 Found credential in configuration file.
113 |    2019/08/11 22:26:54 Succeed to validate AWS credential.
114 |    2019/08/11 22:26:55 Instance in active.
115 |    Welcome to Ubuntu 16.04.5 LTS (GNU/Linux 4.4.0-1088-aws x86_64)
116 |    
117 |    ...
118 |    
119 |    New release '18.04.2 LTS' available.
120 |    Run 'do-release-upgrade' to upgrade to it.
121 |    
122 |

124 |    ubuntu@testbed:~$
125 |    ```
126 |    
127 |    > **Tip** : If a instance is in STOP state, 'connect' command automatically start the instance and connect SSH. So you don't need to command 'start' actually. Just use **connect**!
128 |    
129 |    Or, you can use user-defined key in ec2_connect_config.yaml by specifying --key. By default, this script uses "default" key in config file.
130 | 
131 |    ```
132 |    $ ec2-connect connect Test --key=MY_CUSTOM_KEY_PATH
133 |    ```
134 | 
135 | 
136 | 4. Stop EC2 instance by **ec2-connect stop [EC2 instance name]**
137 | 
138 |    ```
139 |    $ ec2-connect stop Test
140 |    2019/08/11 22:28:12 Cannot found credential in environment variable.
141 |    2019/08/11 22:28:12 Found credential in configuration file.
142 |    2019/08/11 22:28:12 Succeed to validate AWS credential.
143 |    2019/08/11 22:28:12 Stoping EC2 instance : Test (instance ID: i-0994dac6654fd59e1)
144 |    2019/08/11 22:28:13 Succeed to stop EC2 instances.
145 |    ```
146 | 
147 | 5. If you defined **custom group** in /etc/ec2_connect_config.yaml, you can use 'group start' or 'group stop'
148 | 
149 |    ```
150 |    $ ec2-connect group start kubeadm_part
151 |    2019/08/11 22:29:07 Cannot found credential in environment variable.
152 |    2019/08/11 22:29:07 Found credential in configuration file.
153 |    2019/08/11 22:29:08 Succeed to validate AWS credential.
154 |    2019/08/11 22:29:08 Starting EC2 instance : kubeadm-master (instance ID: i-04f9e3d...)
155 |    2019/08/11 22:29:08 Starting EC2 instance : kubeadm-worker0 (instance ID: i-0c35c71...)
156 |    2019/08/11 22:29:08 Succeed to start EC2 instances.
157 |    ...
158 |    ```
