O & M platform-based saltstack and jinja2 templates to build a high-availability cluster configuration platform

Preface:

I am working on a cluster configuration platform recently. I have also done a similar demo before. I remember that I used the paramiko module last year. I first said that I used ssh to configure the connection, pexpect is also sometimes used for interaction. In complex configurations, problems often occur. The configuration mainly involves the regular expression matching.

Now we are in a new company. The first thing we need to do is to refactor the code to build a configuration tool for the whole network cluster and support platforms for nginx, lvs, and haproxy cluster configuration. It contains automatic flow approval of processes, tests on the test server, configurations before the configuration file operations, and rollback when a problem occurs.

Because the new company's environment is puppet, I plan to promote saltstack! I still like saltsatck's simple secondary development.

My current thinking is:

Use a web framework template to render configuration. It is best to convert nginx. conf keepalived. conf to a format similar to yaml. Push to the client is only a get url. Through the ip address and type of the interface, you can render the configuration file and download it directly.

This can be said to be useless ~ Ah .... I 'd better push saltsatck as much as possible ~

In the following cluster management platform, I wrote it for two days and designed the front-end page and the back-end mysql database. I will update the subsequent ideas and solutions to you. It hasn't been launched yet, just for your reference ~

There is nothing at the front end, that is, the verification of some forms and the js Special Effects of beautification.

Some problems occurred when mysqldb obtained timestamp. For details, refer to the following section ~

ValueErrorValueError: unsupported format character 'm' (0x6d) at index 138Traceback (most recent call last)

This is required for the % symbol, especially for the formatting time.

FROM_UNIXTIME(unix_timestamp(ltime),"%%m-%%d %%H:%%i")
