Getting this error: "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"
I was following this yt tutorial: https://www.youtube.com/watch?v=voWo0hF8mQQ

Make sure your instance has codedeploy agent successfully installed and is in running state.
you can follow this link to install code deploy agent on your instance.

I'm trying to deploy a new version of my Python/Django application using CodePipeline.
I getting error while my code doploy using CodePipeline in AWS elastickbeanstlak. error is below.
Deployment completed, but with errors: During an aborted deployment, some instances may have deployed the new application version. To ensure all instances are running the same version, re-deploy the appropriate application version. Failed to deploy application. Unsuccessful command execution on instance id(s) 'i-0a0aff674bd64310b'. Aborting the operation. [Instance: i-0a0aff674bd64310b] Command failed on instance. Return code: 1 Output: Engine execution has encountered an error.. Instance deployment failed. For details, see 'eb-engine.log'.
The same says in the health status at AWS Console. Elastic Beanstalk marks it as Degraded.
I reboot instance, rebulid elastic beanstalk application.
How can i solve this issue. please help me.
When I try to run codedeploy, I get the following error :
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.
When I look at the ec2 instances created by the auto scalable group, they are both running, and status is passed 2/2 checks passed in green. I am wondering if this is just a catch all error, because its supposed to throw this error if one or both or all are not running.
It seems it wanted an appspec.yml. I am not sure why a appspec.yml is needed, If you create the autodeploy group, and create the codedeploy application, why is there a need for a appspec.yml. I am using jenkins to run the code deploy. I gave it a appspec.yml that is empty, and seems to work.
My CloudFormation stack produces a ScalingGroup which has MinSize and MaxSize set to 1. It also creates a DeploymentGroup that targets this ScalingGroup.
When the deploymentgroup is configured with Configuration name CodeDeployDefault.OneAtATime then the deployment starts successfully.
When the deploymentgroup is configured with Configuration name CodeDeployDefault.AllAtOnce then upon the creation of the stack, the codedeploy doesn't do anything and you can't see any events or log traces on the EC2. There is only one mention to error code HEALTH_CONSTRAINTS. If I terminate the instance, then the scaling group launches a new instance but CodeDeploy doesn't do anything again. If I manually start a deployment with CodeDeployDefault.OneAtATime then it works.
From what i've read in the documentation, this should not happen
There should be no health checks because no instances exists in the deployment group
CodeDeployDefault.AllAtOnce has a minimum health percentage of 0. So it could be that the reason to raise the error is that it equaled 0 and it decided to not continue with the health error code
CodeDeployDefault.AllAtOnce mentions and that should be my understanding, that it is not going to do a heath check because conceptually there is no point, as all instances will be configured at the same time.
Is my expectation or correct or am I do something wrong?
The error code HEALTH_CONSTRAINTS means CodeDeploy deployment failed and the configured healthy hosts ratio is not satisfied. You might want to got to the AWS CodeDeploy console and click on the deployment that created during the during the CloudFormation running process, and the check why the deployment failed. The different between CodeDeployDefault.OneAtATime and CodeDeployDefault.AllAtOnce can be found here: http://docs.aws.amazon.com/codedeploy/latest/userguide/deployment-configurations.html
CodeDeployDefault.AllAtOnce Attempts to deploy an application revision to as many instances as possible at once. The status of the overall deployment will be displayed as Succeeded if the application revision is deployed to one or more of the instances. The status of the overall deployment will be displayed as Failed if the application revision is not deployed to any of the instances. Using an example of nine instances, CodeDeployDefault.AllAtOnce will attempt to deploy to all nine instances at once. The overall deployment will succeed if deployment to even a single instance is successful; it will fail only if deployments to all nine instances fail.
CodeDeployDefault.OneAtATime Deploys the application revision to only one instance at a time.
For deployment groups that contain more than one instance:
The overall deployment succeeds if the application revision is deployed to all of the instances. The exception to this rule is if deployment to the last instance fails, the overall deployment still succeeds. This is because AWS CodeDeploy allows only one instance at a time to be taken offline with the CodeDeployDefault.OneAtATime configuration.
The overall deployment fails as soon as the application revision fails to be deployed to any but the last instance.
In an example using nine instances, it will deploy to one instance at a time. The overall deployment succeeds if deployment to the first eight instances is successful; the overall deployment fails if deployment to any of the first eight instances fails.
For deployment groups that contain only one instance, the overall deployment is successful only if deployment to the single instance is successful.
Since your deployment group only contains one single instance, if you set CodeDeployDefault.OneAtATime and the single instance deployment failed, the deployment will still be marked as succeeded. Please check the deployment details on AWS CodeDeploy console.
I try to deploy a zip on EBS. There is one EC2 and the environment health is green and seems to be fine. I try to deploy a zip and I get:
ERROR During an aborted deployment, some instances may have deployed the new application version. To ensure all instances are running the same version, re-deploy the appropriate application version.
ERROR Failed to deploy application.
ERROR Unsuccessful command execution on instance id(s) 'xxx'. Aborting the operation.
I deploy 10 zip's but all the same issue. I even tried to redeploy the zip which is also deployed at the moment (tried several times) but even that is not possible. What could be the issue?
Some configuration:
Environment type: Load balanced, auto scaling
Number instances: 1 - 1 (tried 1-2, and 0-2)
Instance type: t2.medium
I can only deploy succesfully if I terminate the ec2's manually and start a new deployment before the ec2's are scaled up again.
I was also facing the same issue. Couldn't deploy old builds or even the current one. It suddenly started working after a while, seems like an temporary issue with AWS.
I am working with Blue/Green Deployment using AWS CodeDeploy. The sample deployment provided by AWS is working fine but when I am doing the same thing using custom Deployment, I am getting the following error:
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. (Error code: HEALTH_CONSTRAINTS)
Can anyone help me with this?
You get this error when 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. You can check which lifecycle event failed for the instance and what is the error, also it would be helpful to log in to the failed instance and check the host agent logs.
