Amazon CodeDeploy. Deployment failed

问题:

I have been configuring AWS CodeDeploy for a few days and my first deployment is failing. The error message I get reads "The overall deployment failed because too many individual instances failed deployment, too few healthy instances are available for deployment, or some instances in your deployment group are experiencing problems."

To get more detailed info I have installed the AWS CodeDeploy agent on the Windows instance and it appears not to be working. All what I manage to read in the code-deploy-agent-log.txt file are the repetitive lines.

2016-05-31 16:05:24 DEBUG [codedeploy-agent(4872)]: InstanceAgent::Plugins::CodeDeployPlugin::CommandPoller: Sleeping 90 seconds. 2016-05-31 16:06:55 DEBUG [codedeploy-agent(4872)]: InstanceAgent::Plugins::CodeDeployPlugin::CommandPoller: Calling PollHostCommand: 2016-05-31 16:06:55 INFO [codedeploy-agent(4872)]: Version file found in C:/ProgramData/Amazon/CodeDeploy/.version. 2016-05-31 16:06:55 ERROR [codedeploy-agent(4872)]: InstanceAgent::Plugins::CodeDeployPlugin::CommandPoller: Missing credentials - please check if this instance was started with an IAM instance profile

My question is how can I get more information about the error message I am getting over the deployments. Which credentials am I missing (specifying incorrectly) that cause to the error message in the log file?

回答1:

I think you are missing service-role-arn while creating your deployment group. The service role ARN allows AWS CodeDeploy to act on the user's behalf when interacting with AWS services. The service role ARN is of the code deploy role that you may have created it earlier.

In addition please make sure that your deployment policy is set to CodeDeployDefault.OneAtATime. This is to avoid taking all instances down if you push incorrect or failing build.

I tried Suken Shah's steps it didn't solve for me. What solved for me are:

1)Creating an IamInstanceProfile say Webserver.

2)Adding AWSCodeDeployRole to the IamInstanceProfile Webserver.

3)Adding the following to AWSCodeDeployRole's Trust Relationship: "codedeploy.amazonaws.com", "ec2.amazonaws.com", "codedeploy.MY_REGION.amazonaws.com"

4)Rebooting the ec2

Make sure the role you use for EC2 has 'AWSCodeDeployRole' policy and trust relationship has 'ec2.amazonaws.com' service. if you need to change the role then restart the EC2
