Title:
cloud-init crash on EC2 datasources when IMDS returns an error
Status in cloud-init:
Fix Released
Bug description:
Hello,
We are using the EC2 datasource for crawling the metadata and in our
cloud provider, if the IMDS returns an 404 error on one metadata
resource, cloud-init crashes and the setup fails.
Here is the configuration
```/etc/cloud/cloud.cfg.d/99_metadata.cfg
disable-ec2-metadata: false
datasource_list: [ Ec2 ]
datasource:
Ec2:
strict_id: false
metadata_urls: [ 'http://169.254.169.254:80' ]
timeout: 5
max_wait: 10
```
Here is the log of the error
```
