The previous developer is unreachable, so I don't even know which account they managed it from. And the company does not have any credential details.
The only thing I can locate is
bitnami_credentials on the AWS EC2 instance(s).
From your message I assume you do have access to the SSH credentials, that is great since you then have full access to the data.
Fortunately there is a way to get the IDs for the AWS account, the instance and image used. Run the command below inside the AWS instance(s):
If you have access to the account in the output, then you will be able to manage that instance via the AWS console.
If you do not, we would recommend you to migrate all the data to a new instance, or to export the stack-specific configuration.
To get the information you request see below:
- Configuration used by the installation: Identify the Bitnami stack at /opt/bitnami. You will be able to launch a similar stack via https://bitnami.com/stacks and migrate the data from the old instance.
- Deployment logic: Note that Bitnami stacks are pre-configured. If you mean things such as Ansible recipes, unfortunately there's little we can do as that is usually managed externally to the instances.
