Module config 

SSH configuration and management

This module provides the SshConfig struct which encapsulates all the information needed to establish an SSH connection to a remote host, including credentials and target host socket address.

Key Components

• Connection configuration combining credentials and target host socket address
• Socket address management (IP address and port) for remote instances
• Integration with SSH credentials for authentication

The connection configuration is used by SSH clients to establish secure connections for remote command execution.

Structs

SshConfig

SSH connection configuration for a specific remote instance.

SshConnectionConfig

SSH connection behavior configuration

Constants

DEFAULT_CONNECT_TIMEOUT_SECS

Default SSH connection timeout in seconds

DEFAULT_MAX_RETRY_ATTEMPTS

Default maximum number of connection retry attempts. Set to 60 to allow up to 300 seconds total wait time (60 attempts × 5 second interval). Cloud-init provisioning (user creation, SSH key injection) can take over 3 minutes on some providers and small machines, so a 5-minute budget is used as the default.

DEFAULT_RETRY_INTERVAL_SECS

Default retry interval in seconds

DEFAULT_RETRY_LOG_FREQUENCY

Default retry log frequency (log every N attempts)

DEFAULT_SSH_PORT

Default SSH port number.
