[FEATURE REQUEST] - Command health check

[devops-rob]

At the moment i have these two resources

resource "container" "postgres" {
    network {
        id = variable.psql_network.id
        ip_address = variable.psql_network.ip_address
        aliases = variable.psql_network.aliases
    }


    image {
        name = "postgres:${variable.postgres_version}"
    }

    port {
        local  = variable.postgres_local_port
        host   = variable.postgres_host_port
        remote = variable.postgres_remote_port
    }

    environment = {
        POSTGRES_USER     = variable.postgres_user
        POSTGRES_PASSWORD = variable.postgres_password
    }

    volume {
        source      = "./directory/postgres/files/"
        destination = "/files"
    }
}

resource "remote_exec" "exec_container" {
  target = resource.container.postgres.id

  command = [
    "sh",
    "./files/psql-check.sh",
  ]
}

The second resource is pretty much a healthcheck to ensure that postgres is up, running, and ready to accept connections.

It would be great if we could use the inbuilt healthcheck instead but rather than a http healthcheck, it runs a command inside the container, or runs a script and you can define what code/codes are deemed to be healthy.

Below is a psuedo code example

    health_check {
        command  = ["vault", "status"]
        script = <<EOF
        #!/bin/bash
        EOF

        exit_code = [0,255]
    }

It would use either command, or script, not both. Script allows for inline bash to be written.
