Overview
slingnode.ethereum_node_mgmt is an Ansible role that facilitates common management tasks on servers running Ethereum clients. It is designed to seamlessly work with nodes deployed using slingnode.ethereum role.
The role supports the following tasks:
validator key import (using command line or Key Manager API)
Slashing protection DB import and export
The role uses ephemeral containers to carry out command line tasks. The management commands must be executed in the containers with the same configuration (image version, data directories, users, etc) as the Client containers. This is the default for the role and if you don't change any of the paths, you don't need to worry about any of that.
Command line output
Importing keys using command line as well as importing/exporting slashing protection DB tasks execute commands in short lived containers. This poses a challenge knowing what whether the command executed successfully (the container exit status is the same regardles if the command was successfull or not). Implemented logging configuration addresses this issue. Refer to Logging section.
The API based key import task executes directly on the managed host and does not use a container.
