[Buildroot] [PATCH v6 3/5] docker-engine: new package

Christian Stewart christian at paral.in
Mon Jul 4 19:26:20 UTC 2016


Docker is a platform to build, ship, and run applications in portable
containers.

Signed-off-by: Christian Stewart <christian at paral.in>

---

Changes since v1:
 - use call github to build source URL
Changes since v3:
 - fix help indentation in Config.in
 - use HOST_GO_TARGET_ENV as a base for build env vars
 - cleanup build commands
 - cleanup GOPATH and vendor directory setup
 - Remove selections for graph drivers. Docker will gracefully degrade
   at runtime to the best available graphdriver. It is unnecessary to
   disable these at build time, or to pull in any other dependencies
   like aufs-util or btrfs tools. The daemon will use whatever is
   available at runtime.
Changes since v4:
 - remove commit hash from version scheme
Changes since v5:
 - re-introduce graphdriver selections
 - these selections are required for btrfs and devicemapper
 - there are buildtime dependencies on headers.
 - bump to v1.12.0-rc3
 - remove hack/vendor.sh call, it is unnecessary, dependencies are
   pre-vendored into the source tree.
