First, thanks to those who wrote this lab. It really helped me get started with IOS-XR automation.
For those of you working your way through the IOS-XR CLI automation - Bash lab in the DevNet Sandbox, here is a list of fixes to help you complete this lab.
For all steps, the documentation on https://developer.cisco.com/learning/lab/01-iosxr-01-cli-automation-bash references 10.10.20.170. This is not the IP address you need to use. On the Lab Management screen, look in the left-hand Instructions box, under IOS XR Programmability, for the correct IP address to use throughout the lab. Both times I started this lab, my IP was 10.10.20.70.
Under Step 3, before you can complete the section "Automating the entire process", you must first create the admin account's public keys. You can do this by issuing ssh-keygen from the admin account. It will look similar to the following, obviously the key information and randomart will be different:
devbox:~admin@devbox:~$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/admin/.ssh/id_rsa): NOTE: LEAVE AS DEFAULT, HIT ENTER
Enter passphrase (empty for no passphrase): NOTE: LEAVE BLANK, HIT ENTER
Enter same passphrase again: NOTE: LEAVE BLANK, HIT ENTER
Your identification has been saved in /home/admin/.ssh/id_rsa.
Your public key has been saved in /home/admin/.ssh/id_rsa.pub.
The key fingerprint is: SHA256:InGWweqgng1ObkPKuJ8oMw5pOwxc9HMoisF0ZmgbeOU admin@devbox
The key's randomart image is:
+---[RSA 2048]----+
|. ..... |
|.=.* .o |
|+.B E.= |
|.o.o.B . |
|ooooo + S |
|+B .. . |
|#.+ |
|O%.o |
|*B= |
+----[SHA256]-----+
devbox:~admin@devbox:~$
Under Step 4, the first section you will encounter is "Using Ansible with ZTP bash utilities" / "Pull a docker image with the latest Ansible code". Based on other forum posts, you cannot reach Docker's repository from these labs. Fortunately, the docker image has already been pulled into this lab. First, you need to verify that your lab already has the image by doing the following:
devbox:~admin@devbox:~$ docker images

If you have akshshar/ansible-docker in your list, you are good to move on to the next subsection: "Analyze the Ansible Playbook in the cloned git repo". If not, I spent a lot of time trying to find a workaround before I actually checked "docker images".
