Transparently use ssh-agent on linux/darwin #312

johnmccabe · 2021-02-28T22:23:24Z

Description

This fixes #311.

Attempt to create the ssh connection using a pre-existing ssh-agent first, this will allow users with pre-configured agents, yubikeys etc on Linux and Darwin to establish ssh connections without resorting to private keys.

If this first connection attempt fails we fall through to the existing key based auth flow.

Note that Windows is not supported in this PR as yubikeys do not currently use the ssh-agent.

NOTE this does not include an update to the join command or docs pending an OK on the install implementation.

Motivation and Context

I have raised an issue to propose this change (required)

How Has This Been Tested?

OSX
- Using Yubikey, key present in ssh-agent, prompted for key pin, install completes successfully
- Using private key file (existing flow), install completes successfully
Windows 10
- Using private key file (existing flow), install completes successfully

Types of changes

Bug fix (non-breaking change which fixes an issue)
New feature (non-breaking change which adds functionality)
Breaking change (fix or feature that would cause existing functionality to change)

May be worth enabling in Windows for users with pre-configured ssh-agents.

Have you got instructions for trying this out with a Yubikey?

What's the additional latency when an SSH agent isn't in use and the initial attempt fails?

Could the existing behaviour run if and only if SSH_AUTH_SOCK is undefined?

Could the new behaviour run when a flag is passed? --ssh-agent / -a

Negligible

Could the existing behaviour run if and only if SSH_AUTH_SOCK is undefined?

Can you clarify the use case here?

Could the new behaviour run when a flag is passed? --ssh-agent / -a

Can you clarify the use case here? Pass the flag where, when etc

Looks good to me. In the hashi-up project, the SSH_AUTH_SOCK is used by default, without a fallback but rather displaying an error message when no identities are loaded in the agent. Implementing a fallback like this will not break the existing behaviour of k3sup.

Trying the ssh-agent first will solve a couple of issues, like #311 #255 #99

alexellis · 2021-03-03T20:53:13Z

Could the existing behaviour run if and only if SSH_AUTH_SOCK is undefined?

What I am trying to say is that if SSH_AUTH_SOCK is not defined as an env-var, then my understanding is that an agent isn't in use. So can we skip the agent in that case?

Is this still WIP, or does it cover the Join command now? @johnmccabe

Support for join added, verified with both a simple cluster and a multi-master HA setup.

Note that I've not attempted to refactor the SSH flows to avoid overloading the PR. There is definitely some scope for tidying the existing structure and reducing the duplication somewhat.

johnmccabe · 2021-03-27T20:08:06Z

Just some additional testing to complete here and it should be good. Adding the support for Krypton would be trivial (see #318).
