Job Allocations

In Maand, when a job is assigned to a worker, it is referred to as an allocation. Allocations are determined based on the matching labels and selectors between jobs and worker.

Viewing Job Allocations

To see the current job allocations, use the command:

$ maand cat allocations

This displays which jobs are assigned to which workers, along with their statuses.

Explanation of Columns

• worker_ip: The IP address of the worker to which the job is allocated.
• job: The name of the allocated job.
• disabled: A value of 0 indicates that the job is enabled.
• removed: A value of 0 indicates that the job was allocated to that agent and later removed.

How Allocations Work

1. Build Configuration:

   • Allocations are prepared during the maand build process.

2. Update Agents:

   • Allocations are applied to agents during the maand deploy process.

By inspecting the allocations table, you can confirm which jobs are running/ will be on which workers.
