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

---
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.
Changes since v6:
- remove build-time dependency on docker-containerd and runc
- install dockerd only if daemon is enabled
- move all daemon dependencies into daemon selection
- only install sysv, users, etc if daemon is enabled
- add a proper sysv init file
- remove DOCKER_OPTS in init file
- remove test for $BASH as bash is never used for init
- use hash for documentation link in sysv init file
- remove unnecessary path change in sysv init file
- remove exit on error line in sysv init file
- remove init info comment from sysv init file
Changes since v7:
- remove "-static" cgo flag which fixes build of btrfs and other
additional filesystem drivers.
- build + run test with alternate filesystem drivers.
Changes since v8:
- Bump to v1.12.0-rc4
