Vendoring
=========
The Go code in this repo depends on a number of Go libraries.
These are vendored in to the `src/cmd/linuxkit/vendor` directory using [`vndr`](https://github.com/lk4d4/vndr)
The `vendor.conf` file contains a list of the repositories and the git SHA or branch name that should be vendored
## Updating dependencies
Update `src/cmd/linuxkit/vendor.conf` with the dependency that you would like to add.
Details of usage of the `vndr` tool and the format of `vendor.conf` can be found [here](https://github.com/LK4D4/vndr/blob/master/README.md)
Once done, you must run the `vndr` tool to add the necessary files to the `vendor` directory.
The easiest way to do this is in a container.
Currently if updating `github.com/moby/tool` it is also necessary to
update `src/cmd/linuxkit/build.go` manually after updating `vendor.conf`:
hash=$(awk '/^github.com\/moby\/tool/ { print $2 }' src/cmd/linuxkit/vendor.conf)
curl -fsSL -o src/cmd/linuxkit/build.go https://raw.githubusercontent.com/moby/tool/${hash}/cmd/moby/build.go
## Updating in a container
To update all dependencies:
```
docker run -it --rm \
-v $(pwd):/go/src/github.com/linuxkit/linuxkit \
-w /go/src/github.com/linuxkit/linuxkit/src/cmd/linuxkit \
--entrypoint /go/bin/vndr \
linuxkit/go-compile:a8bffe875268a973ea82e5937b0fb23a5b08cc79
```
To update a single dependency:
```
docker run -it --rm \
-v $(pwd):/go/src/github.com/linuxkit/linuxkit \
-w /go/src/github.com/linuxkit/linuxkit/src/cmd/linuxkit \
--entrypoint /go/bin/vndr \
linuxkit/go-compile:a8bffe875268a973ea82e5937b0fb23a5b08cc79
github.com/docker/docker
```
## Updating locally
First you must install `vndr` and ensure that `$GOPATH/bin` is on your `$PATH`
```
go get -u github.com/LK4D4/vndr
```
To update all dependencies:
```
cd src/cmd/linuxkit
vndr
```
To update a single dependency:
```
cd /src/cmd/linuxkit
vndr github.com/docker/docker
```
