This exception appears to affect ansible when a playbook is executed from a host with several identities configured in the SSH agent (Tested on a development machine with 12 private keys).

I've noted this exception to be particulary common with AWS targets

Inventory configuration

Most tasks will run fine when we configure our inventory to use a specific private key.

We also need to set the IdentitiesOnly flag so that ssh does not attempt other authentication strategies.

Run commands on remote Docker host

This is how to connect to another host with your docker client, without modifying your local Docker installation or when you don't have a local Docker installation.

Enable Docker Remote API

First be sure to enable the Docker Remote API on the remote host.

This can easily be done with a container.
For HTTP connection use jarkt/docker-remote-api.

	This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

	usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

	Getting help:
	-h — print basic options
	-h long — print more options
	-h full — print all options (including all format and codec specific options, very long)
