Amazon EC2 Code Deploy No hosts succeeded - amazon

Question

I am new with Amazon Code Deploy. I am getting an error when deploying
Deployment Failed
No hosts succeeded
I checked the service code deploy-agent on my Linux machine and it's running
How can I fix this issue?

Answer 1

Most of the time this issue occur due to insufficient IAM Permission on the Instance and CodeDeploy Service. You need to check /var/log/aws/codedeploy-agent/codedeploy-agent.log file for detail information. Also in /etc/codedeploy-agent/conf/codedeployagent.yml file you can set :verbose: true to get more info in log file.
These are the IAM Policies you need to update :
// Policy Role for Code Deploy
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"autoscaling:PutLifecycleHook",
"autoscaling:DeleteLifecycleHook",
"autoscaling:RecordLifecycleActionHeartbeat",
"autoscaling:CompleteLifecycleAction",
"autoscaling:DescribeAutoscalingGroups",
"autoscaling:PutInstanceInStandby",
"autoscaling:PutInstanceInService",
"ec2:Describe*"
],
"Effect": "Allow",
"Resource": "*"
}
]
}
// Policy Trust for Code Deploy
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "",
"Effect": "Allow",
"Principal": {
"Service": [
"codedeploy.us-west-2.amazonaws.com",
"codedeploy.us-east-1.amazonaws.com"
]
},
"Action": "sts:AssumeRole"
}
]
}
// Instance Role for EC2 Instance
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"s3:Get*",
"s3:List*"
],
"Effect": "Allow",
"Resource": "*"
}
]
}

As BrunoLevy said, we will need more information about the the deployments you were trying to do.
However as a starting point for debugging, you can observe in which step your deployment failed from the deployment page
You can also look at the host agent log file on your hosts (/var/log/aws/codedeploy-agent/codedeploy-agent.log). That file contains information about the deployment.

This happens because the codeDeploy checks health of the ec2 instances by hitting instances. Before deployment, you need to run below bash script on the instances and check if the script worked. httpd service must be started. Reboot the instance.
#!/bin/bash
sudo su
yum update -y
yum install httpd -y
yum install ruby
yum install aws-cli
cd ~
aws s3 cp s3://aws-codedeploy-us-east-1/latest/install . --region us-east-1
chmod +x ./install auto
./install auto
echo 'hello world' > /var/www/html/index.html
hostname >> /var/www/html/index.html
chkconfig httpd on
service httpd start
