It would be very helpful to be able to do the following to set up the Docker environment vars to use sdc-docker:

eval $(triton docker-env)

That would set the local environment based on the user's current active profile. Users can then switch back to a local docker using standard Docker Machine:

eval $(docker-machine env lappy)

This is desirable to reduce friction in initial Docker setup for Triton and when switching back and forth.

The triton syntax above intentionally omits the option of configuring the Docker environment to connect to a different data center/profile. This is to eliminate confusion that results from using docker and triton in parallel, but unintentionally connected to different DCs. @tgross and I have started to protect against that using checks like those in https://github.com/tgross/triton-touchbase/blob/master/start.sh#L55-L75, but it would be best to make the tools assume they're connecting using the same profile from the start.

^^^ added all but step #4 of the proposal. Given that I'm going away for a week, I don't want to push a new release until I'm back (in case this breaks people). So we'll let it soak a bit.

@misterbisson +1. Definitely room to re-imagine sdc-docker-setup.sh using triton. triton docker env or triton docker-env (with support for triton's profiles) would be fairly straightforward I think. It could do the cert setup on first run and cache the necessary data.

I also have a triton setup dream, BTW.

Proposal:

Getting triton to help setup for Docker usage.
A.k.a. "sdc-docker-setup.sh sucks".

First time user

1. In the browser/email, create an account with Joyent:

   https://my.joyent.com
   

   Note that this has a number of redirects (and needing to find the "Sign up"
   link) that make it more jarring than it needs to be. Having a nice
   link for signing up would be nice.

   ... presuming they are fine creating an account and being led through
   adding an SSH key.

2. In the shell, install triton and setup for docker usage

   # install node/npm
   npm install -g triton
   # optionally install triton bash completion
   triton profile create   # defaults to us-sw-1
   

   Perhaps we could setup for docker during triton profile create. We already
   hit CloudAPI anyway. If CloudAPI ListServices has "docker" then we do the
   docker setup as well.

3. Use docker:

   eval "$(triton env)"
   docker run joyent/hello-world
   

   We already have triton env to set SDC_ and TRITON_ envvars. We could
   add the DOCKER_ envvars as well.

4. Optionally: Use triton docker to run docker without having to change
   one's environment.

   triton docker run joyent/hello-world
   

Users with triton profiles already that now want Docker setup for them

Users like me. :)

triton profile docker-setup

This would do the Docker-part of the profile setup for the current profile.
Might like to do that for another profile:

triton profile docker-setup east3b

from node-triton.

version 4.9.0 published. This leaves:

1. triton docker ... nicety -> #105
2. deprecating sdc-docker-setup.sh and relevant docs (https://docs.joyent.com/private-cloud/install/client-setup https://docs.joyent.com/private-cloud/hybrid-cloud) -> https://smartos.org/bugview/DOCKER-766

from node-triton.

The biggest update is in https://docs.joyent.com/public-cloud/api-access/docker, but there are a lot of results for google: site:www.joyent.com/blog "sdc-docker-setup.sh" and google: "sdc-docker-setup.sh" -inurl:joyent.com/blog
