Ansible tricks - Chạy một role từ command line

Khi viết một role cho ansible role, thi thoảng tôi muốn chạy luôn role này. Hoặc có 1 role tôi clone được từ github. Đôi khi chỉ có một role thôi nên rất ngại viết hẳn một playbook đẻ chỉ chạy mỗi role đó.
ansible-role sẽ cứu rỗi ta, làm công việc nhanh chóng hơn.

Cài đặt ansible-role

sudo pip install ansible-role

Sau khi cài đặt, ta thấy ansible-role có các options như

Ví dụ

Ta có 1 role ntp-client

Muốn chạy role này ta thực hiện lệnh sau

ansible-role --module-path .  ntp-client  ntp -i hosts -u root

--module-path: Đường dẫn tới module
ntp-client: tên của role
-i hosts: inventory host
-u root: remote user

Kết quả

Ta có thể thấy hiện tại ansible-role đã hỗ trợ tất cả các tham số của ansible-playbook, do vậy ta có thể thoải mái làm việc với ansible-role mà ít bị hạn chế bởi những options.

Zabbix, AWS and Auto Registration

One of the things I love the most with AWS is auto-scaling . You choose an AMI, set some parameters and AWS will spin instances up and down whenever a threshold is breached. But with all these instances spinning up and down there are some unknowns. For example, what is the IP address of the new instance? Its host name? This can be critical when other components of your infrastructure are dependent on knowing these parameters. I had this problem when I started to use Zabbix as the monitoring system. At first it seemed like a complicated one, but Zabbix has a wonderful feature called Auto Registration which can be used exactly for this situation. I will try to show how to configure auto registration both on the client (EC2 instance running Ubuntu 14.04) and on the Zabbix server (Zabbix Server 2.4.2). Zabbix-agent Installation and Configuration Let’s start with installing zabbix-agent on the Ubuntu client: 1 2 $ sudo apt-get update $ sud...

Merge AVHDX Hyper-V Checkpoints

When you create a snapshot of a virtual machine in Microsoft Hyper-V, a new file is created with the .avhdx file extension. The name of the file begins with the name of its parent VHDX file, but it also has a GUID following that, uniquely representing that checkpoint (sometimes called snapshots). You can see an example of this in the Windows Explorer screenshot below. Creating lots of snapshots will result in many .avhdx files, which can quickly become unmanageable. Consequently, you might want to merge these files together. If you want to merge the .avhdx file with its parent .vhdx file, it’s quite easy to accomplish. PowerShell Method Windows 10 includes support for a Merge-VHD PowerShell command, which is incredibly easy to use. In fact, you don’t even need to be running PowerShell “as Administrator” in order to merge VHDX files that you have access to. All you need to do is call Merge-VHD with the...

SIPp cheatsheet

SIPp is a free test tool and traffic generator for the SIP protocol. It uses XML format files to define test scenarios. General usage: sipp remote_host[:remote_port] [options] Some important command-line options: -sf filename Load test scenario from specified file. -inf filename Use CSV file to insert data substituted for [field0], [field1], etc into XML scenario. First line of file describes order of inserting field sets (SEQUENTIAL/RANDOM/USE). -sn name Use one of the embedded, predefined scenarios like "uac", "uas". -r rate Scenario execution rate, default value = 10 times per period, default period = 1000 ms. -rp period Scenario execution period [ms], combined with execution rate. Execution rate is combined of rate and period parameters, i.e. if period = 3500 and rate = 7 there will be 7 calls in 3.5 s. -t transport mode Set the transport mode: "u1" - UDP, one socket (default), "un" - UDP, one socket per call, other modes (...
