An example job in the UI templates to show off actions and how they work.

I'm a bit on the fence about the last action. While cool, the awk script is quite complex and I think a bit distracting for the purpose of the job.

If you want to curl something Nomad related you could add some ASCII art to https://github.com/hashicorp/nomad/tree/main/website/public/data

Note: used roughly this example job for the tutorial proposed at https://github.com/hashicorp/tutorials/pull/1814

Minor nit-picks but LGTM!

Like above, we can probably use port mapping to keep this a bit cleaner and avoid the extra args, but if you want to use dynamic ports something like this would be a bit easier to understand?

job "example" {
  group "cache" {
    network {
      port "db" {}
    }

    task "redis" {
      driver = "docker"

      config {
        image   = "redis:7"
        ports   = ["db"]
        args    = ["/etc/redis/redis.conf"]
        volumes = ["local/conf:/etc/redis"]
      }

      template {
        data        = <<EOF
port {{env "NOMAD_PORT_db"}}
EOF
        destination = "local/conf/redis.conf"
      }
    }
  }
}

Then the redis-cli -p \${NOMAD_PORT_db} DBSIZE command in db_log.sh could be another action?

I realize it's not practical or desired for a real-world redis server on Nomad, but it seemed cool to illustrate db size output live when you make edits via action.

In the (pending) actions tutorial (PR), I hoped this would be something easily demonstrable to a user.
