provisioning tool focused on performance.
Project description
Because ops can dev.
nuka is a provisioning tool focused on performance. It massively uses Asyncio and SSH. It is compatible with docker vagrant and apache-libcloud.
Full documentation is available at
Quickstart
Install nuka (See Installation for detailled steps):
$ pip install "nuka[full]"
Then start a script:
#!/usr/bin/env python3.5 import nuka from nuka.hosts import DockerContainer from nuka.tasks import (shell, file) # setup a docker container using the default image host = DockerContainer('mycontainer') async def do_something(host): # we just echoing something using the shell.command task await shell.command(['echo', 'it works'], host=host) # if no host is provided, then a var named `host` is searched # from the stack. Mean that this will works to await shell.command(['echo', 'it works too']) async def do_something_else(host): # log /etc/resolv.conf content res = await file.cat('/etc/resolv.conf') host.log.info(res.content) # those coroutines will run in parallell nuka.run( do_something(host), do_something_else(host), )
Run it using:
$ chmod +x your_file.py $ ./your_file.py -v
The first run will be slow because we have to pull the docker image. The next run will take approximately 1s.
Get some help:
$ ./your_file.py -h
Look at the generated gantt of your deployement:
$ firefox .nuka/reports/your_file_gantt.html
You’ll get a dynamic report like this screenshot:
