@dnephin @thaJeztah I closed and re-opend #348 since the tests did not get triggered on push.
I hope it's OK if we continue the discussion here.

LGTM

liron-l · 2017-07-20T18:43:14Z

@dnephin thanks! I think that the commit approval is what's causing the builds to stop.

dnephin · 2017-07-20T18:46:32Z

Hmm, I don't know about that. We approve plenty of PRs that are still able to build afterward.

I think it's something about the files/changes. On my PR which had this issue (#107) I also retried recreating it, and after the first build it also stopped building again, and the new PR doesn't have any approvals.

liron-l · 2017-07-20T18:52:14Z

Makes sense @dnephin. Let me know what further steps are required to complete this PR.

dnephin · 2017-07-20T19:04:04Z

Once someone else gives their approval we can run the tests manually and merge. Let's not worry about the github bug for now

liron-l · 2017-07-20T19:04:24Z

Great @dnephin thanks!

liron-l · 2017-07-25T13:45:15Z

@thaJeztah PTAL, I separated vendor.conf bump to another commit.
Let me know if I need to bump additional packages. Thanks!

liron-l · 2017-07-30T11:40:37Z

@thaJeztah @cpuguy83 please take a look, I've updated the docker vendor dependencies again. Thanks!

@thaJeztah PTAL

liron-l · 2017-08-13T06:25:26Z

@vdemeester, @cpuguy83, @diogomonica, @thaJeztah, should I add additional changes to this commit?

thaJeztah · 2017-08-14T08:33:23Z

 	}
 	flags := cmd.Flags()
 	flags.VarP(&options.labels, "label", "l", "Secret labels")
+	flags.StringVar(&options.driver, "driver", "", "Secret driver")


This flag needs to have a version annotation, so that it is hidden / produces an error on older API versions

Also, to be consistent with docker network create, docker volume create, in this case I would be +1 to add a -d shorthand as well

Thanks @thaJeztah I set the version annotation to 1.31, hope this makes sense.

thaJeztah · 2017-08-14T08:53:34Z

- in = file
- defer file.Close()
+	if options.driver != "" && options.file != "" {
+ return errors.Errorf("When using secret driver secret data must be empty")


Could this be handled by the (external) driver? IIUC, with this change the secret's value is taken from the external store, so
$ docker secret create --driver external mysecret
Doesn't really "create" a secret, but "associates" the external secret with a secret in Docker.
Do we need to keep the option open to have external secret stores create new secrets from the Docker CLI? i.e.
$ echo"new secret"| docker secret create --driver external mysecret -
If so, this validation should be done by the driver (just like currently checking for empty values is done in the backend)
$ docker secret create foo Error response from daemon: rpc error: code = InvalidArgument desc = secret data must be larger than 0 and less than 512000 bytes

@thaJeztah according to the secrets plugin subsystem design, the secrets plugin will be readonly (that is, swarm will not populate the secret values).
I think it might be better to prevent incorrect usage as soon as possible (since file is a cli only option).

liron-l · 2017-08-14T10:03:44Z

Thanks @thaJeztah, I've updated the review according to your comments.

Set minimum version for --secret parameter (1.31)
Kept the CLI validation, according to the secret plugin design, we will never populate the secrets from the cli. In the context of plugins, the creation means that we create a real secret in swarmkit (secret name and metadata) and only the value is fetched from the plugin.

liron-l · 2017-08-18T19:27:17Z

@thaJeztah @diogomonica I've updated the code, please take a look if the new secrets driver API makes sense.

liron-l · 2017-08-21T19:42:43Z

@diogomonica @thaJeztah PTAL.

liron-l · 2017-08-27T20:12:00Z

@thaJeztah PTAL, let me know if additional changes are required.

liron-l · 2017-09-03T20:38:49Z

@diogomonica @thaJeztah PTAL, all other dependencies related to this feature are completed. Thanks.
