# Development Report for June 12, 2017

## Moby Summit

The next Moby Summit will be at Docker HQ on June 19th, register [here](https://www.eventbrite.com/e/moby-summit-tickets-34483396768)

## Daily Meeting

### The CLI split

Manpages and docs yaml files can now be generated on [docker/cli](https://github.com/docker/cli).
Man pages, docs and completion scripts will be removed next week thanks to @tiborvass 

### Find a good and non-confusing home for the remaining monolith

Lots of discussion happened on the [forums](https://forums.mobyproject.org/t/topic-find-a-good-an-non-confusing-home-for-the-remaining-monolith)
We should expect to do those changes after the moby summit. We contacted GitHub to work with them so we have a smooth move.

### Moby tool

`moby` tool docs were moved from [LinuxKit](https://github.com/linuxkit/linuxkit) to the [moby tool repo](https://github.com/moby/tool) thanks to @justincormack

### Custom golang URLs

More discussions on the [forums](https://forums.mobyproject.org/t/cutoms-golang-urls), no agreement for now.

### Buildkit

[Proposal](https://github.com/moby/moby/issues/32925)

More updates to the [POC repo](https://github.com/tonistiigi/buildkit_poc). It now contains binaries for the daemon and client. Examples directory shows a way for invoking a build job by generating the internal low-level build graph definition with a helper binary(as there is not support for frontends yet). The grpc control server binary can be built in two versions, one that connects to containerD socket and other that doesn't have any external dependencies.

If you have questions or want to help, stop by the issues section of that repo or the proposal in moby/moby.

#### Typed Dockerfile parsing

[PR](https://github.com/moby/moby/pull/33492)

New PR that enables parsing Dockerfiles into typed structures so they can be preprocessed to eliminate unnecessary build stages and reused with different kinds of dispatchers.

#### Long running session & incremental file sending

[PR ](https://github.com/moby/moby/pull/32677) 

Same status as last week. The PR went through one pass of review from @dnephin and has been rebased again. Maintainers are encouraged to give this one a review so it can be included in `v17.07` release.


#### Quality: Dependency interface switch

[Move file copying from the daemon to the builder](https://github.com/moby/moby/pull/33454) PR is waiting for a second review. 

#### Proposals for new Dockerfile features that need design feedback:

[Add IMPORT/EXPORT commands to Dockerfile](https://github.com/moby/moby/issues/32100)

[Add `DOCKEROS/DOCKERARCH` default ARG to Dockerfile](https://github.com/moby/moby/issues/32487)

[Add support for `RUN --mount`](https://github.com/moby/moby/issues/32507)

[DAG image builder](https://github.com/moby/moby/issues/32550)

[Option to export the hash of the build context](https://github.com/moby/moby/issues/32963) (new)

[Allow --cache-from=*](https://github.com/moby/moby/issues/33002#issuecomment-299041162) (new)

[Provide advanced .dockeringore use-cases](https://github.com/moby/moby/issues/12886) [2](https://github.com/moby/moby/issues/12886#issuecomment-306247989)

If you are interested in implementing any of them, leave a comment on the specific issues.

#### Builder features currently in code-review:

[Warn/deprecate continuing on empty lines in `Dockerfile`](https://github.com/moby/moby/pull/29161)

[Fix behavior of absolute paths in .dockerignore](https://github.com/moby/moby/pull/32088)

#### Backlog

[Build secrets](https://github.com/moby/moby/issues/33343) has not got much traction. If you want this feature to become a reality, please make yourself heard.
