I set up the pipeline three months ago and everything has been running fine with the same appspec.yml. But now suddenly AWS CodeDeploy gives the error that it can't find the appspec.yml although it is already there.It failed at the very first ApplicationStop event itself. The error is as follows:
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)
Then when I looked into the details, this is what it said:
My appspec.yml is as follows:
version: 0.0
os: windows
files:
- source: \
destination: c:\home\afb
file_exists_behavior: OVERWRITE
I also have the folder (c:\home\afb) created already on my EC2 instance. The health of the EC2 instance is fine as I can see on the Dashboard and also access it via RDP. The CodeDeploy agent is also running fine on EC2.
Please help. Thanks in advance for any advice!
