lets try to put a clearer name of the scenario here, think this current name can get confusing

We might want to add a reference around setting up aws secrets similar to node scenarios: https://github.com/krkn-chaos/krkn/blob/main/docs/node_scenarios.md#aws. This way they do not get exposed in the stdout. Thoughts?

agree on this, we currently configure aws connection just based on enviornment variables we should see if we can do the same set up here

...and maybe drop the ebs
from the name to make it CSP-agnostic?

If the aws cli is configured it should take those credentials if other are not specified so I will put the reference how to setup the credentials in documentation and will remove the option to put there different credentials

We might want to introduce a cloud_type variable which is set to aws in this case as we will be adding support for Azure and GCP as well for this scenario. For example: https://github.com/krkn-chaos/krkn/blob/main/scenarios/openshift/aws_node_scenarios.yml#L10

The goal is to use the same config and load things differently based on the cloud_type.
Is there any reason why this functionality shouldn't be implemented as a new scenario of |
Agree with @pablomh that we can make it as an additional action in the node-scenarios - https://github.com/krkn-chaos/krkn/blob/main/scenarios/openshift/aws_node_scenarios.yml where the parameters are similar for aws, gcp, azure - node name to target, volume id etc and we run the detach logic based on cloud_provider set ( aws, gcp etc. ) |

let's be sure the logging information here matches the action we are doing, should be something like "Starting to detach disk"
