Installing tmux-256color for macOS

• macOS 10.15.5
• tmux 3.1b

macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):

Triggering a Cron Job manually on Kubernetes

So you've defined a cronjob.yaml manifest, but it doesn't run until midnight and you want to test it now? Simply replace the variables, and run the following command to create a job from the cronjob.

kubectl create job --from=cronjob/{{ cron_job_name }} {{ the-name-of-this-one-off-job }}

This will create a one-off job in your cluster based on your cronjob.yaml manifest, which might look something like this.
