1.1 File status uses the template parameter-template: jinja
1.2 variables in the template file use {{name}} `PORT `
1.3list of variables-defaults:
PORT: 8080
two。 Practical application
Add listening host and port variabl
Vim / srv/salt/devfiles/httpd.conf
Listen `HOST `: `PORT`
# `MAC `
Configure salt master profile, pillar profile, lamp.sls add jinja template:
