 ## Known Limitations
 
 The Podman task driver is under active development. It currently does not support [stderr logging][stderr-logging] and [devices][devices].
-Podman recently released [Podman v2](https://podman.io/blogs/2020/06/29/podman-v2-announce.html). The task driver currently supports v1
-and will be working on supporting v2 in upcoming releases.
 
 ## Task Configuration
 
 Due to Podman's similarity to Docker, the example job created by [`nomad init -short`][nomad-init] is easily adapted to use Podman instead:
 
 ```hcl
-job "example" {
+job "redis" {
   datacenters = ["dc1"]
-  network {
-    port  "db"  {
-      to = 6379
-    }
-  }
+  type        = "service"
 
   group "cache" {
+    network {
+      port "redis" { to = 6379 }
+    }
+
     task "redis" {
       driver = "podman"
 
       config {
