     1  # rkt enter
     2  
     3  Given a pod UUID, if you want to enter a running pod to explore its filesystem or see what's running you can use rkt enter.
     4  
     5  ```
     6  # rkt enter 76dc6286
     7  Pod contains multiple apps:
     8          redis
     9          etcd
    10  Unable to determine app name: specify app using "rkt enter --app= ..."
    11  
    12  # rkt enter --app=redis 76dc6286
    13  No command specified, assuming "/bin/bash"

    19  ## Use a Custom Stage 1
    20  
    21  rkt is designed and intended to be modular, using a [staged architecture](devel/architecture.md).
    22  
    23  You can use a custom stage1 by using the `--stage1-image` flag.
    24  
    25  ```
    26  # rkt --stage1-image=/tmp/stage1.aci run coreos.com/etcd:v2.0.0
    27  ```
    28  
    29  For more details see the [hacking documentation](hacking.md).
