mesos-go-stateful

An abstraction on top of mesos-go for steteful workload

Sample Run

1. Download the codegen Package

$go get -v github.com/huawei-cloudfederation/mesos-go-stateful/codegen
github.com/samuel/go-zookeeper (download)
.
.
.
github.com/huawei-cloudfederation/mesos-go-stateful/common/types
github.com/huawei-cloudfederation/mesos-go-stateful/codegen

2. codegen utility would have been installed

$codegen -h
Usage of codegen:
  -alsologtostderr
        log to standard error as well as files
  -log_backtrace_at value
        when logging hits line file:N, emit a stack trace (default :0)
  -log_dir string
        If non-empty, write log files in this directory
  -logtostderr
        log to standard error instead of files
  -name string
        Name of the scheduler eg: RedisScheduler or MySQLScheduler (default "Example")
  -path string
        Path where the project needs to be created (default "./")
  -stderrthreshold value
        logs at or above this threshold go to stderr
  -v value
        log level for V logs
  -vmodule value
        comma-separated list of pattern=N settings for file-filtered logging

3. Create a Project for MySQL Stateful Framework

codegen -name MySQL -path /home/ubuntu/workdir
I1113 05:19:45.377934    7471 gen.go:129] Creating Sub-directories at /home/ubuntu/workdir/MySQL.....
I1113 05:19:45.378115    7471 gen.go:153] Generating Scheduler.go...
I1113 05:19:45.378363    7471 gen.go:171] Generating autofilled config file
I1113 05:19:45.378545    7471 gen.go:192] Project Generation Completed

4. Examine the Project

$~/workdir$ ls -lrt MySQL
drwxrwxr-x 2 ubuntu ubuntu 4096 Nov 13 05:19 Scheduler
 |-- -rw-rw-r-- 1 ubuntu ubuntu 1771 Nov 13 05:19 Scheduler.go
drwxrwxr-x 2 ubuntu ubuntu 4096 Nov 13 05:19 Executor
drwxrwxr-x 2 ubuntu ubuntu 4096 Nov 13 05:19 Config
 |-- -rw-rw-r-- 1 ubuntu ubuntu 430 Nov 13 05:19 config.json

5. Update the auto generated config file Config/config.json with your Mesos and etcd/zookeprs endpoint Build the autogenerated Scheduler

$cd /MySQL/Scheduler
$go get -v ./...
$go build Scheduler.go
$./Scheduler
