> I am creating CoreOS nodes, and using cloud-init with them. The cloud-init takes a while
to process.
> 11:42:32.780 [user thread 3] ERROR jclouds.ssh - << (core:rsa[ssh-agent]@1….2)
error acquiring {hostAndPort=1…2:22, loginUser=core, ssh=null, connectTimeout=60000, sessionTimeout=60000}
(not retryable): Exhausted available authentication methods
> net.schmizz.sshj.userauth.UserAuthException: Exhausted available authentication methods
> I’ve set the following overrides:
> 		overrides.setProperty(ComputeServiceProperties.POLL_INITIAL_PERIOD, TWENTY_SECONDS);
> 		overrides.setProperty(ComputeServiceProperties.POLL_MAX_PERIOD, TWENTY_SECONDS);
> 		// 18 retries of 15 seconds --> 4.5 min
> 		overrides.setProperty(Constants.PROPERTY_MAX_RETRIES, "6"); 
> 	overrides.setProperty(Constants.PROPERTY_RETRY_DELAY_START, "15");
> These overrides had no effect.
> 		overrides.setProperty("jclouds.ssh.max-retries", "100");
> 		overrides.setProperty("jclouds.ssh.retry-auth", "true");
> These overrides worked - ssh retries for 100 times, but: the sleep time between retries
is 2s (which should be exponential backoff, and configurable) and - eventually locks down
the ssh agent for "too many retries"
> (the ssh agent is up, it's only that the ssh key was not installed yet...)
> My workaround is to install ssh keys as part of cloud-init, and then everything works
ok, but this is a serious bug, and this workaround will not work in all cases.
> This MAY be related to: https://github.com/jclouds/jclouds-labs-google/pull/118
> PS.
> I setup cloud-init by setting user metadata “user-data”=<the content of the cloud-init.yaml
> cloud-init works, node IS accessible via ssh, and my unit files are up and running.
