Hello,

Thank you for your reply. I tried to add certificate under /etc/docker/certs.d because of the docker documentation (the link you mentioned).

Because the CA used to create the dockerelasticco.crt is not recognized by my docker daemon, I got the message (from my post: unknown authority).  
I'm wondering if there is a specific installation step recommended by Elastic in order to enable authority used to signed the elastic certificate for my docker installation.

It might be also an issue from my network (i.e. some firewall checks for https), however I want to make sure that everything is ok with my local configuration.

Thanks
