+CIAO Scheduler
+==============
+[![](https://images.microbadger.com/badges/image/clearlinux/ciao-scheduler.svg)](http://microbadger.com/images/clearlinux/ciao-scheduler "Get your own image badge on microbadger.com")
+[![](https://images.microbadger.com/badges/version/clearlinux/ciao-scheduler.svg)](http://microbadger.com/images/clearlinux/scheduler "Get your own version badge on microbadger.com")
+
+This provides a CIAO Scheduler container
+
+Features
+--------
+- From source building solution
+- Daemon and Manual service start mode
+- You mess it, just destroy it and start it again
+- Develop on you local development machine and deploy it on containers.
+- No data/binary copies, everything can be accesible from container
+
+Build
+-----
+```
+    docker build -t clearlinux/ciao-scheduler .
+```
+
+Or just pull it from Dockerhub
+------------------------------
+```
+    docker pull clearlinux/ciao-scheduler
+```
+
+Pre-requirements
+----------------
+Before launching scheduler, take a look on [CIAO on top of Docker containers for development]()
+
+Start CIAO Scheduler container
+-----------------------------
+### Run in daemon mode
+```
+export YOUR_HOST=localhost
+docker run -d -it -v --name ciao-scheduler --net=host -v `pwd`/certs/CAcert-$YOUR_HOST.pem:/etc/pki/ciao/CAcert-ciao-dev.pem \
+       -v `pwd`/certs/cert-Scheduler-$YOU_HOST.pem:/etc/pki/ciao/cert-Scheduler-ciao-dev.pem \
+       -e IDENTITY_HOST=$YOUR_HOST \
+       -v $GOPATH/src/github.com/01org/ciao:/root/go/src/github.com/01org/ciao \
+       ciao/scheduler
+```
+
+### Run on manual mode
+```
+export YOUR_HOST=localhost
+docker run -d -it -v --name ciao-scheduler --net=host -v `pwd`/certs/CAcert-$YOUR_HOST.pem:/etc/pki/ciao/CAcert-ciao-dev.pem \
+       -v `pwd`/certs/cert-Scheduler-$YOU_HOST.pem:/etc/pki/ciao/cert-Scheduler-ciao-dev.pem \
+       -e IDENTITY_HOST=$YOUR_HOST \
+       -v $GOPATH/src/github.com/01org/ciao:/root/go/src/github.com/01org/ciao \
+       ciao/scheduler bash
+
+# Inside container
+root@example.com # ls
+ciaorc  go  scheduler.sh share
+
+# Manual Start of Ciao Scheduler
+root@example.com # ./scheduler.sh
+```
+
+### Getting CIAO Scheduler logs from docker
+```
+docker logs -f ciao-scheduler
+```
+
+Environment Variables
+---------------------
+- ``IDENTITY_HOST`` Specifies the Keystone URL. Example: example.com
+
+Extra Build ARGs
+----------------
+- ``swupd_args`` Specifies [SWUPD](https://clearlinux.org/documentation/swupdate_how_to_run_the_updater.html) flags
+
+Default build args in Docker are on: https://docs.docker.com/engine/reference/builder/#/arg
