CloudFoundry Diego auction using mesos | ||
## CloudFoundry-Mesos | ||
|
||
CloudFoundry-Mesos replaces the auctioning process of CloudFoundry Diego with Mesos, and make the Diego auctioneer as a Mesos framework. This project starts as a PoC and is currently under development. The idea is to let CloudFoundry be able to share the same Mesos cluster with other frameworks to get better resource utilization and possibly improve the scalability. | ||
|
||
## Implementation | ||
|
||
* __Create Mesos scheduler and executor__. The scheduler provides two strategies, `binpack` which tries to put CloudFoundry apps into as few cells as possible, and `spread` which is the opposite. Both the strategies base on the RAM usage and the implementation is simply for demo purpose. The executor uses `rep` API to launch and monitor Diego `Tasks` and `LRPs`. | ||
* __Pack Diego `cell` into Docker image__ to minimize the Mesos Slave host system dependency and be able to create a cell on the fly. Due to `Garden-Linux` requirements, the Docker Container is started privileged, uses host network. It also maps two directories for storing data and logs. The executor is packed into this image as well. | ||
|
||
It is considered to make Mesos __[Garden](https://github.com/cloudfoundry-incubator/garden) aware__ so Mesos will see the detail resource usage of each container and there will be container in container stuff. | ||
|
||
* __Create a new `auctionrunner`__ that collects the `auctions` and hands them to the Mesos scheduler. | ||
* __Patch `auctioneer`__ by replace the `auctionrunner` package. | ||
* __Patch `rep`__ so the `/state` API would return not only `LRPs` but the `Tasks` as well (no longer needed in latest version). | ||
|
||
|
||
## Fetures on Mesos | ||
|
||
* __On-demand resource allocation__. CloudFoundry Diego cells are created automatically up to the Mesos cluster size and removed if not needed. | ||
* __Resource sharing__. So the same Mesos cluster can run multiple frameworks for jobs such as Hadoop, Spark, Redis, etc. | ||
* __Scheduling algorithm customization__. | ||
* __Mesos scales to 10,000s of nodes__. This may help increase the CloudFoundry cluster size. | ||
|
||
|
||
## Usage | ||
|
||
To get up and running with CloudFoundry-Mesos, please follow the [Getting Started Guid](./docs/getting-started.md). | ||
|
||
If you are not familiar with CloudFoundry or Mesos, the following documents would help: | ||
* http://docs.cloudfoundry.org/ | ||
* https://github.com/cloudfoundry/cf-release/blob/master/README.md | ||
* https://github.com/cloudfoundry-incubator/diego-release/blob/develop/README.md | ||
* http://bosh.io/docs | ||
* http://mesos.apache.org/documentation/latest/ | ||
|
||
|
||
## Future Work | ||
|
||
* Garden as Mesos Containerizer | ||
* Garden in Docker may not be the right way | ||
* Granular resource monitoring | ||
* Requires Garden pre-installed in each Mesos slave | ||
* Probably requires to patch Diego `rep` and `executor` | ||
* BTRFS=>AUFS transition in latest Garden Linux | ||
* AUFS requires kernel support | ||
* Improve Error Handling | ||
* Scheduling strategy and constrains and more | ||
* Multiple RootFS support | ||
* Test for performance and scalability | ||
* Windows support? | ||
* Put other Cloud Foundry components on Mesos? | ||
* Scale other CF components (router for example) | ||

## Cloudfoundry-Mesos | ||
|
||
This guide applies to the HEAD of the source tree and currently tested only with the following environment: | ||
* `OpenStack Kilo` as IaaS | ||
* `Ubuntu 14.04` with `Docker 1.8.2` installed as Mesos host | ||
* `Mesos 0.25.0` with Docker containerizer enabled | ||
* `CloudFoundry v219`, `Diego v0.1434.0` and `Garden Linux v0.307.0` | ||
|
||
|
||
## Deploy CloudFoundry Diego | ||
|
||
Cloudfoundry-Diego currently tested only with `CloudFoundry v219`, `Diego v0.1434.0` and `Garden Linux v0.307.0`. Please refer to [the Diego release document](https://github.com/cloudfoundry-incubator/diego-release) to deploy the specified version. | ||
|
||
CloudFoundry has two run-time environment, `DEA` and `Diego`, by default the app will be deployed to DEA which is not supported by CloudFoundry-Mesos. Please set the Cloud Controller property `default_to_diego_backend` to `true` in the manifest file when deploying CloudFoundry. | ||
|
||
|
||
## Deploy Mesos | ||
|
||
Cloudfoundry-Diego works with Mesos 0.25.0, the host OS should be `Ubuntu 14.04` (Other distributions not tested) with `Docker 1.8.2` or later installed. | ||
|
||
Please follow the [Mesos](http://mesos.apache.org/gettingstarted/) and/or [MESOSPHERE](https://mesosphere.com/downloads/) documents to install and start a Mesos cluster. | ||
|
||
|
||
## Patch and Build `auctioneer` | ||
|
||
Get Diego release code and make sure you can compile `auctioneer` without a problem | ||
``` BASH | ||
$ git clone https://github.com/cloudfoundry-incubator/diego-release.git | ||
$ cd diego-release | ||
$ git checkout v0.1434.0 | ||
$ ./scripts/update | ||
$ export GOPATH=$(pwd) | ||
$ cd src/github.com/cloudfoundry-incubator/auctioneer/cmd/auctioneer/ | ||
$ go build | ||
|
||
``` | ||
Patch `auctioneer` to use Mesos's `auctionrunner` package | ||
``` BASH | ||
$ sed -i 's|"github.com/cloudfoundry-incubator/auction/auctionrunner"|"github.com/mesos/cloudfoundry-mesos/scheduler/auctionrunner"|g' main.go | ||
``` | ||
Get all the dependencies and rebuild the auctioneer | ||
``` BASH | ||
$ go get ./... | ||
$ go build | ||
``` | ||
|
||
|
||
## Build the Executor | ||
|
||
Build the Mesos executor binary is easy | ||
``` BASH | ||
$ cd ../../../../mesos/cloudfoundry-mesos/executor/ | ||
$ go build | ||
``` | ||
In order to create Diego cells dynamically, this project packs the executor binary together with all the Diego cell jobs in to a big Docker image. Starting this container will config and start Diego cell jobs (consul, metron, rep and garden) and launch the Mesos executor. Note that in order for Diego's `Garden-Linux` to work, the cell container should be running with `host` network and in `privileged` mode. | ||
|
||
The docker images is current manually created in pushed to Docker hub at `jianhuiz/diego-cell:219-1434-307`. You can pull the image and do the customize on top of it. The creation of the image include compile and package CloudFoundry/Diego/Garden binaries and patch the startup scripts. We will automate the image creation and publish the details later. | ||
|
||
## Replace the `auctioneer` | ||
|
||
Find the IP of Diego `brain` VM by running `bosh vms`, this is by default where the `auctioneer` runs. SSH into that host and stop the Diego auctioneer job. | ||
``` BASH | ||
$ sudo monit stop auctioneer | ||
``` | ||
Replace the auctioneer binary file `/var/vcap/packages/auctioneer/bin/auctioneer` with the newly compiled one and patch the auctioneer starting script `/var/vcap/jobs/auctioneer/bin/auctioneer_ctl` with the following new parameters added to the auctioneer start command line: | ||
```BASH | ||
-address 192.168.2.12 \ | ||
-master=zk://192.168.0.15:2181/mesos \ | ||
-auction_strategy=binpack \ | ||
-consul_server=192.168.1.113 \ | ||
-etcd_url=http://192.168.1.109:4001 \ | ||
``` | ||
Where `-address` is the host IP where the auctioneer runs; `-master` is the Mesos master address; `-auction_strategy` is teh scheduling strategy when doing the auctioning; `-consul_server` and `-etcd_url` will be passed to the dynamically created Diego cell to join the CloudFoundry Cosnul server and access the ETCD storage (Note that there are two ETCDs and this is the ETCD of CloudFoundry, not that of Diego). Please replace those parameter values according to your environment. | ||
|
||
Then start the new auctioneer and make sure it's up and running. | ||
```BASH | ||
$ sudo monit start auctioneer | ||
$ sudo monit status | grep -A14 auctioneer | ||
``` | ||
|
||
|
||
## Push CloudFoundry apps | ||
|
||
If you have already set `default_to_diego_backend: true` when deploying CloudFoundry, just run `cf push` to deploy and run a CloudFoundry app with Diego runtime. Otherwise please install [Diego cli plugin](https://github.com/cloudfoundry-incubator/diego-cli-plugin) and [specify diego backend](https://github.com/cloudfoundry-incubator/diego-design-notes/blob/master/migrating-to-diego.md#starting-a-new-application-on-diego) when pushing apps. | ||
|
||
For test purpose, you can just use the [hello world app](https://github.com/jianhuiz/cf-apps/tree/master/hello). Don't forget to modify the `manifest.yml` accordingly. | ||
|
||
Check the app status using `cf app <your-app>` and see the framework and running tasks in Mesos portal. You can also use `cf scale` to change the app instance count and see Mesos tasks created or removed. | ||
|
||
|
||
