Remote Resources MaNaGeMeNT

Intro

This tool helps you manage remote machines and services running on that. It is targeted to Linux based machines. All is done via SSH connection, that means SSH server must be running there already.

from rrmngmnt import Host, RootUser

h = Host("10.11.12.13")
h.users.append(RootUser('123456'))
exec = h.executor()
print exec.run_cmd(['echo', 'Hello World'])

Features

List of provided interfaces to manage resources on machine, and examples.

Filesystem

Basic file operations, you can find there subset of python ‘os’ module related to files.

print h.fs.exists("/path/to/file")
h.fs.chown("/path/to/file", "root", "root")
h.fs.chmod("/path/to/file", "644")
h.fs.unlink("/path/to/file")

In additional there are methods to fetch / put file from / to remote system to / from local system.

h.fs.get("/path/to/remote/file", "/path/to/local/file/or/target/dir")
h.fs.put("/path/to/local/file", "/path/to/remote/file/or/target/dir")

There is one special method which allows transfer file between hosts.

h1.fs.transfer(
    "/path/to/file/on/h1",
    h2, "/path/to/file/on/h2/or/target/dir",
)

You can also mount devices.

with h.fs.mount_point(
    '//example.com/share', opts='ro,guest',
    fstype='cifs', target='/mnt/netdisk'
) as mp:
    h.fs.listdir(mp.target) # list mounted directory
    mp.remount('rw,sync,guest') # remount with different options
    h.fs.touch('%s/new_file' % mp.target) # touch file

Firewall

Allows to manage firewall configurarion. Check which firewall service is running on host (firewalld/iptables) and make configure this service.

h.firewall.is_active('iptables')
h.firewall.chain('OUTPUT').list_rules()
h.firewall.chain('OUTPUT').add_rule('1.1.1.1', 'DROP')

Network

It allows to manage network configuration.

print h.network.hostname
h.network.hostname = "my.machine.org"
print h.network.all_interfaces()
print h.network.list_bridges()

Package Management

It encapsulates various package managements. It is able to determine which package management to use. You can still specify package management explicitly.

Implemented managements:

  • APT
  • YUM
  • DNF
  • RPM
# install htop package using implicit management
h.package_management.install('htop')
# remove htop package using rpm explicitly
h.package_management('rpm').remove('htop')

System Services

You can toggle system services, it encapsulates various service managements. It is able to determine which service management to use in most cases.

Implemented managements:

  • Systemd
  • SysVinit
  • InitCtl
if h.service('httpd').status():
    h.service('httpd').stop()
if h.service('httpd').is_enabled():
    h.service('httpd').disable()

Operating System Info

Host provide os attribute which allows obtain basic operating system info. Note that os.release_info depends on systemd init system.

print h.os.distribution
# Distribution(distname='Fedora', version='23', id='Twenty Three')

print h.os.release_info
# {'HOME_URL': 'https://fedoraproject.org/',
#  'ID': 'fedora',
#  'NAME': 'Fedora',
#  'PRETTY_NAME': 'Fedora 23 (Workstation Edition)',
#  'VARIANT': 'Workstation Edition',
#  'VARIANT_ID': 'workstation',
#  'VERSION': '23 (Workstation Edition)',
#  'VERSION_ID': '23',
#  ...
# }

print h.os.release_str
# Fedora release 23 (Twenty Three)

Storage Management

It is in PROGRESS state. Planed are NFS & LVM services.

Power Management

Give you possibility to control host power state, you can restart, poweron, poweroff host and get host power status.

Implemented managements:

  • SSH
  • IPMI
ipmi_user = User(pm_user, pm_password)
ipmi_params = {
    'pm_if_type': 'lan',
    'pm_address': 'test-mgmt.testdomain',
    'user': ipmi_user
}
h.add_power_manager(
    power_manager.IPMI_TYPE, **ipmi_params
)
# restart host via ipmitool
h.power_manager.restart()

Requires

  • paramiko
  • netaddr
  • six
