Go dependencies are managed using
the godep tool. build/dep.sh is an ease of
use wrapper around godep.
dep.sh COMMAND ...
Manages godep dependencies. This mostly a wrapper around operations
involving godep and a Docker image containing a clean copy of the
dependencies.
image
Create image with godep dependencies (k8s-dns-godep).
verify
Verify that the godep matches the dependencies in the code. Exits
with success if there are no differences.
enter [-u]
Run Docker container interactively to manage godep. If -u is
specified, then update the image with changes made.
save [PKG1 PKG2 ...]
save PKGs as new dependencies. Note: the PKGs must be referenced
from the code, otherwise godep will ignore the new packages.
-h|--help
This help message.
USAGE
Add a new package:
# Add import reference of acme.com/widget.
$ vi pkg/foo.go
# Add widget to the vendor directory. This should modify the godep
# file appropriately.
$ build/dep.sh save acme.com/widget
Updating a package:
(It is recommended to do this manually due to the fragility of godep update)
# Enter the container interactively.
$ build/dep.sh enter -u
# inside container
$ rm -rf /src/$DEP # repo root
$ go get $DEP/...
# Change code in Kubernetes, if necessary.
$ rm -rf Godeps
$ rm -rf vendor
$ ./build/dep.sh save
$ exit
$ git checkout -- $(git status -s | grep "^ D" | awk '{print $2}' | grep ^Godeps)
Verifying Godeps.json match:
$ build/dep.sh verify
