gron

SystemD and cron inspired job scheduler

Usage

1. Create gron.d directory

2. Create job config in gron.d/job1.conf (TOML format):

   Type                   = "cmd"        # command execution
   Cron                   = "* * * * *"  # cron instructions
   
   Command                = "echo Hello" # command to execute
   

   SQL job:

   Type                   = "sql"                            # sql execution
   Cron                   = "* * * * *"                      # cron instructions
   Description            = "execute procedure every minute" # job description
   
   Driver                 = "pgx"                            # "pgx" for Postgresql, "oracle" for Oracle, "sqlserver" for Microsoft SQL Server
   ConnectionString       = "postgres://login:password@host:port/database?sslmode=disable" # each driver has different syntax
   SqlText                = "CALL procedure"                 # command to execute
   

   Add other options if needed:

   Description            = "print Hello every minute" # job description
   NumberOfRestartAttemts = 3                          # number of restart attemts
   RestartSec             = 5                          # the time to sleep before restarting a job (seconds)
   RestartRule            = "on-error"                 # Configures whether the job shall be restarted when the job process exits
