> Found while fixing CAMEL-26191. The socket connection mode of camel-docker
> does not work as documented.
> * {{DockerConfiguration.socket}} is documented with {{defaultValue = "true"}}
> (endpoint option, and the {{CamelDockerSocketEnabled}} header in
> {{DockerConstants}}), but the field is a plain {{boolean}} that defaults to
> {{false}}. So by default the component connects to {{tcp://localhost:2375}}
> (the unencrypted TCP port of the daemon, which Docker does not open by
> default), not to the local socket.
> * With {{socket=true}}, {{DockerClientProfile.toUrl()}} builds
> {{unix://<host>}}. With the default {{host=localhost}} that is
> {{unix://localhost}}, which cannot connect (Netty: {{connect(..) failed
> error(-22) Invalid argument}}). It only works when {{host}} is set to the
> socket path, such as {{/var/run/docker.sock}}, which the docs do not say.
> To decide: make the documented default true and use {{/var/run/docker.sock}}
> when the socket mode is on and host is the default {{localhost}}; or keep TCP
> as the default and fix the documented default to false. Either way the docs
> should say that in socket mode {{host}} is the path of the socket.
> Upgrade-guide entry if the default changes.
