Implemented for fun. Original task text can be found here or check local copy.
go get github.com/ptqa/resource_manager
go install github.com/ptqa/resource_manager
As written in golang can be runned as single binary:
resource_manager
Uses config.json in the same dir. Example:
{
"Port":3000,
"Limit":5,
"Workers":128
}Where:
- Port -- HTTP port for running server
- Limit -- how many resources should we create
- Workers -- ammount of concurrent workers (for parallel allocate/deallocate)
Resource manager uses goconvey for testing. Running and checking coverage is simple:
go get github.com/smartystreets/goconvey
$GOPATH/bin/goconvey
After opening a broser at http://127.1:8080/ you should be able to see somethin like that:
Interactive (logs will appear in stdout):
docker run -it -e PORT=5000 -e WORKERS=3 -e LIMIT=100 -p 5000:5000 ptqa/resm
Daemon:
docker run -d -e PORT=5000 -e WORKERS=3 -e LIMIT=100 -p 5000:5000 ptqa/resm
This will run resource manager with 100 resources, 3 workers and listening on port 5000. After that you should be able to make a query:
$ curl 127.1:5000/list
