Support for Windows named pipes mounts #2691

olljanat · 2018-07-06T20:49:29Z

Support for Windows named pipes mounts

- What I did
Added support for mount type npipe same way than it is added for engine on: moby/moby#33852

- How I did it
Added protocol NPIPE and command line switch --npipe

- How to test it
Build on Windows:

mkdir bin
$env:GOOS="windows"
$env:GOARCH="amd64"
go build -o .\bin\swarmd.exe .\cmd\swarmd\main.go
go build -o .\bin\swarmctl.exe .\cmd\swarmctl\main.go

Deploy my test version of Portainer using command:

.\swarmctl.exe service create --name portainer --npipe \\.\pipe\docker_engine:\\.\pipe\docker_engine --ports 9000:9000 --image ollijanatuinen/portainer:windows1803-amd64-npipe-3

Check using docker ps which port container actually is running (some reason source port is randomly selected), connect it from another machine (because on Windows limit of network connections) and test that Portainer can connect to local docker (environment type local and Windows containers which on).

Pre-requirement for moby/moby#37400 to be able to fix moby/moby#34795

- Description for the changelog

502d108 => Added type NPIPE to be able to use it with SwarmKit
3ece1d6 => Added Windows specific default settings for swarmd to be able to run tests on Windows.
b37c210 => Corrected --npipe parameter parsing.

i'm not sure how, but the proto messages have gotten messed up. you'll need to re-run make generate. if make generate produces identical output, i think your version of protobuild may be out-of-date, in which case re-running make setup should get you up-to-date.

olljanat · 2018-07-06T22:56:34Z

@dperny issue looks to be 3.0 version of protobuf which comes using apt-get install protobuf-compiler
It started to working after I manually installed same version than there is on circleci config.

Dockerfile which creates build/test environment with correct versions of tools would be nice.

There looks to be still some other issues too. I will investigate more them on tomorrow/next week.

@johnstep @cpuguy83 should we have more/other validation here? (don't know if there's a utility somewhere to validate these)

@thaJeztah good question, there looks to be quite a lot validations on engine side already. Is there is any point to duplicate them to here?

This looked to be much bigger task than I expected so it can take while before I'm sure that PR is OK (even from my point of view).

Anyway, after my second commit it is now possible to build and run swarmd on Windows. Main functionality was added on a1c8923 but default settings was incorrect.

Build on Windows can be done using following commands:

mkdir bin
$env:GOOS="windows"
$env:GOARCH="amd64"
go build -o .\bin\swarmd.exe .\cmd\swarmd\main.go
go build -o .\bin\swarmctl.exe .\cmd\swarmctl\main.go

And after that you can just start swarmd without any extra parameters:

bin\swarmd.exe

Maybe we should also add Windows CI builds to here?

OK. I got it working on my env now and updated testing information to first post.

Please, review.

dperny · 2018-07-09T17:57:31Z

@olljanat i have a PR out right now for a dockerfile actually, right here: #2687. feel free to take that for a spin and let me know if it does the job for you.

olljanat · 2018-07-11T14:52:03Z

@thaJeztah I changed that one test which you picked up and now this looks working correctly. First post contains all info how to test. Can you review or ask someone else do so?

cpuguy83 · 2018-07-12T22:36:12Z

This looks OK.
I wonder if we should add a node filter for supported mount types on a node (just as a thought separate from this proposal).

Please sign your commits following these rules:
https://github.com/moby/moby/blob/master/CONTRIBUTING.md#sign-your-work
The easiest way to do this is to amend the last commit:

$ git clone -b "34795-npipe-mount-type" [email protected]:olljanat/swarmkit.git somewhere
$ cd somewhere
$ git rebase -i HEAD~842354049336
editor opens
change each 'pick' to 'edit'
save the file and quit
$ git commit --amend -s --no-edit
$ git rebase --continue # and repeat the amend for each commit
$ git push -f

Amending updates the existing PR. You DO NOT need to open a new one.

@anshulpundir @cyli I can see that you have been active here on lately. Can I ask you review this one too or ping someone who can?

Portainer.io recently introduced Windows containers support using named pipe and it would be very nice to be able do deployment without extra tweaking (step 4 on this).

I will be also offline next three weeks starting from weekend so if this need changes I would like handle them still during this week.

cyli · 2018-08-01T20:55:23Z

The code LGTM - I'm not super familiar with the mount types and the docker PR itself - cc @johnstep possibly?

olljanat · 2018-08-02T15:48:59Z

Maybe @jhowardmsft also knows this stuff?

olljanat · 2018-08-22T19:51:45Z

ping @cyli @johnstep any possibility to get this one forward?

olljanat · 2018-08-28T13:02:30Z

@thaJeztah @dperny can you review this one?

dperny · 2018-08-28T16:31:19Z

LGTM now. I believe you will also need to update the executor in moby/moby to have this work all the way through.

olljanat · 2018-08-28T16:49:58Z

@dperny This worked fine with moby/moby without executor changes when I tested it on July but I will of course test it again after this on is merged and updated to there.

Who can do merging?

Vacant0mens · 2018-08-31T20:46:29Z

Any update on this? I would really love to get service discovery going by reading the default npipe so that i don't have to map docker to a TCP port.

olljanat · 2018-09-03T06:23:09Z

@thaJeztah @cyli @dperny @anshulpundir there is two "LGTM" comments here already so can someone merge this one?

thaJeztah · 2018-09-06T09:40:20Z

I don't have permissions to merge. @anshulpundir @dperny ok to merge this one?

ggruber4711 · 2018-10-20T12:45:36Z

When will this feature be available in Docker-ee for windows?

olljanat · 2018-10-20T13:09:43Z

@ggruber4711 as far I have understood this will be available for Docker CE on 19.03 and hopefully quite soon after that also Docker EE version will be released.

Docker EE 18.03.1 was released three months after Docker CE 18.03.0 so I guess that it will be some where on next June.

@thaJeztah any comments?

thaJeztah · 2018-10-22T12:16:06Z

Yes, this didn't make it for the 18.09 release, so will be in the release after that (19.03).

and hopefully quite soon after that also Docker EE version will be released.

Going forward, Docker CE and Docker EE will be released in sync again, so they should be released at the same time

Vacant0mens · 2019-07-19T15:08:41Z

@thaJeztah Is there a short and long syntax for this? or is it only allowed in short syntax for Stacks? Volumes aren't described very in-depth in the Stack File documentation (as compared to the Compose File documentation).
Also, I see this was added to the 19.03 release, is the EE version 19.03.0-rc2 included as well, or is it just CE so far?

olljanat · 2019-07-19T15:21:48Z

@Vacant0mens only long syntax works. Look example on moby/moby#37400 (comment)

Both CE and EE will have same features on 19.03 so this will be included to both of them.

Vacant0mens · 2019-07-19T15:41:07Z

Thanks @olljanat . Is there a scheduled release date for 19.03 for EE? I saw earlier that CE was already released, just wanted to know what to expect. I'd like to get off the -rc2 version as soon as I can.

Vacant0mens · 2019-07-19T16:24:40Z

@olljanat
Looks like the documentation for Compose and for Stacks will need to be updated to reflect your example.

Also, I'm not sure if this is a bug or not, but it seems that the npipe volume mapping is incompatible when used along side other volumes or volume types.

version: '3.7'
services:
  portainer:
    image: portainer/portainer:windows1809-amd64
    ports:
      - 9000:9000
    volumes:
      - E:\Portainer:C:\data
      - type: npipe
        source: \\.\pipe\docker_engine
        target: \\.\pipe\docker_engine

If I docker stack deploy this file, I get the error starting container failed: hcsshim::CreateComputeSystem [guid]: The request is not supported. . But if I remove the line - E:\Portainer:C:\data , it deploys and starts the service with no issues. I get the same error if I use the long syntax with - type: bind.

olljanat · 2019-07-19T16:32:35Z

@Vacant0mens are you sure that folder E:\Portainer exists and that it works without npipe line? If so then please report it as new issue to moby/moby.

Docs update PR is open on docker/docs#7427

Vacant0mens · 2019-07-19T16:43:58Z

Yes, I'm sure because this works:

docker run -d -p 9000:9000 --name portainer --restart always -v \\.\pipe\docker_engine:\\.\pipe\docker_engine -v E:\Portainer:C:\data portainer/portainer:windows1809-amd64

I'll open a new issue as you said.
