# AWS Code Deploy to EC2

## Code deploy to EC2 instance using Code deploy Agent 

\
Let’s start first by creating 2 **IAM roles** we will use in this tutorial:‌

* IAM role for **CodeDeploy** to talk to **EC2** instances.
* IAM role for **EC2** to access **S3**.

**1 — CodeDeployRole**‌

Go to [AWS IAM Console](https://console.aws.amazon.com/iam/home) then navigate to “**Roles**“, choose “**Create New Role**“, Select “**CodeDeploy**” and attach “**AWSCodeDeployRole**” policy:​‌

**2 — EC2S3Role**‌

Create another **IAM** role, but this time choose **EC2** as the trusted entity. Then, attach “**AmazonS3ReadOnlyAccess**” policy:​‌

Now that we’ve created an IAM roles, let’s launch an EC2 instance which will be used by CodeDeploy to deploy our application.‌

**3 — EC2 Instance**‌

Launch a new **EC2** instance with the IAM role we created in last section:​ and add proper tag on EC2 instance.

Next to **User Data** type the following script to install the **AWS CodeDeploy Agent** at boot time:Plain Text exit: ⌘↩

```
#!/bin/sh
 yum update
 yum install -y ruby
 cd /home/ec2-user
 aws s3 cp s3://aws-codedeploy-us-west-1/latest/install .
 chmod +x ./install
 ./install auto
```

Note: make sure to allow **HTTP** traffic in the security group.​‌

Once created, connect to the instance using the **Public IP** via **SSH**, and verify whether the **CodeDeploy** agent is running:​‌

**4 — Application**‌

Add the *appspec.yml* file to the application to describe to AWS CodeDeploy how to manage the lifecycle of your application:Plain Text exit: ⌘↩

```
‌version: 0.0
os: linux
files:
  - source: /
    destination: /home/ec2-user/api
permissions:
  - object: /
    pattern: "**"
    owner: ec2-user
    group: ec2-user
hooks:
  AfterInstall:
    - location: deploy/before_install.sh
      timeout: 1200
      runas: ec2-user
  ApplicationStart:
    - location: deploy/restart.sh
      timeout: 60
      runas: ec2-user
ValidateService:
    - location: deploy/validate.sh
      timeout: 60
      runas: ec2-user
```

**`Branch - travis-ci-codedeploy-ec2`**

## Now Lets build Pipeline Step by Step&#x20;

1. Create Pipeline and name it as Code-deploy-ec2-node and ass source provider as Github

![](/files/-LkIRbPa8TqcYSPuTIGK)

Add Build Stage Next after setting up Source Repository with Branch, From here create new Build Project&#x20;

![](/files/-LkIRs38Sb2lxyCtw0ps)

Add Build configuration with default  build spec file which says just copy node JS code to Artifacts&#x20;

![](/files/-LkID2kLOo9lhM9FejmF)

finally add this  build  as  a Stage to Pipeline&#x20;

![](/files/-LkIS2bwpg2uzg2fBoqZ)

Add deployment PROVIDER as code deploy and Configure application and return back to same screen (Create code deploy application and deployment group )

![](/files/-LkITYP56yt9ZZRNhTFl)

### Code deploy application&#x20;

Crate code deploy application and code deploy group&#x20;

![](/files/-LkITp8VBdDn3StlGGVL)

Code deploy can push code to EC2 instance so lets spin up EC2 instance having S3 read only access role&#x20;

![](/files/-LkITsLN2L3ratMO_SU5)

In User data we can add installation commands to add code deploy agent to EC2 instance as startup script&#x20;

![](/files/-LkITwVLtIFdfH-MYLEl)

Define Tag for EC2 instance so these EC2 instance can be provided as Target for Code deploy stage&#x20;

![](/files/-LkIU0Gi-TKbCr94e4iT)

Create Deployment Group&#x20;

![](/files/-LkIU3KRvQD398RY4B5y)

Once Code deployment created add Code deploy to our pipeline Last step&#x20;

![](/files/-LkIU5xl6XIjFs-dfQm5)

Now Our Pipeline has ben setup with Code Build and Code deploy to push Node JS Code TO ec2 instance&#x20;

![](/files/-LkIU8gi0Sk_MGuW6_zG)

![](/files/-LkIUB4zojvr2srb_GFS)

Trigger a dummy Commit to run pipeline&#x20;

![](/files/-LkIUDTJsEBa8MAM58_K)

![](/files/-LkIUFvpYJYXAph6wrdG)

Here we see everything worked as expected and we are able to see application deployed on EC2 instance&#x20;
