Support configs for Swarm mode services

[thojkooi]

In Docker 17.06.0 the concept of configs are introduced:

Add support for services to carry arbitrary config objects moby/moby#32336, docker/cli#45, moby/moby#33169

https://github.com/docker/docker-ce/releases/tag/v17.06.0-ce

---

• Config endpoints are available in the Docker remote API under /configs.
• The implementation and interface is similar to secrets.
  • This would cover the ability to create, inspect and remove a config. Updating does not seem to be supported by the API.
  • and be able to assign a config to a service, and remove it. Just like the Service Secrets.

Documentation:

• https://docs.docker.com/engine/reference/commandline/config/

I'm happy to do the work on the initial implementation.

@Glowbal @deviantony What is this issue exactly? As far as I can see, config has been implemented and released in stable
This issue confused me into thinking that docker configs, for now, only works in docker on single hosts (not in Swarm mode). But it seems to work very good in swarm mode.

@artheus as @Glowbal specified in the issue description, this is to add Docker config (https://docs.docker.com/engine/reference/commandline/config/) support inside Portainer.

I think that Docker configs can only be used within Swarm services (like the secrets). What config are you talking about ? What stable version are you talking about?

[thojkooi]

This issue is indeed about the config support in Swarm mode, which is available since Docker 17.06. Docker configs indeed only work in Swarm mode.

So what's the status of this issue? Will portainer support swarm config introduced by Docker 17.06?

[deviantony]

@zhaoyao91 there is a work in progress on this, follow #996
