Issue with Open NX-OS with Nexus 9Kv sandbox

bill.smith — Fri, 25 Oct 2019 20:08:15 GMT

I am going through the Getting Hands On with Ansible lab and running into an issue trying to perform the initial steps to install ansible 2.2 and clone sample code from git. If this access is no longer allowed is there a workaround?

(venv) [root@devbox ~]# pip install ansible==2.2
Collecting ansible==2.2
Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x7f6225087b38>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution',)': /simple/ansible/
Could not find a version that satisfies the requirement ansible==2.2 (from versions: )

Hi Bill, I am sorry to hear you are having an issue with this lab, allow me to help. The sandbox's had a security posture change a few months back, as such tools and repo's were preinstalled. Once you have entered the virtual environment, you can check the installed Ansible

(venv) [developer@devbox ~]$pip freeze | grep ansible
ansible==2.6.2
(venv) [developer@devbox ~]$which ansible
~/venv/bin/ansible
(venv) [developer@devbox ~]$which ansible-playbook
~/venv/bin/ansible-playbook
(venv) [developer@devbox ~]$

From here, now change your directory to code/sbx_nxos

(venv) [developer@devbox ~]$cd code/sbx_nxos/
(venv) [developer@devbox sbx_nxos]$pwd
/home/developer/code/sbx_nxos

From here you can access the learning labs

(venv) [developer@devbox sbx_nxos]$cd learning_labs/
(venv) [developer@devbox learning_labs]$ls
LM-1451 intro-ansible  LM-5601 intro-nxos  poap  README.md  telemetry  yang

Bonus tip! Check to see if your switches are online

(venv) [developer@devbox learning_labs]$cd .
(venv) [developer@devbox sbx_nxos]$pwd
/home/developer/code/sbx_nxos
(venv) [developer@devbox learning_labs]$virl ls --all

Warning, this can take a little time! Pro tip: Coffee time! When this is ready, all nodes will say 'reachable' you can ping these. You can also ssh and console into the Nexus.

Thanks that has me moving along again! The lab is having me log in as root so once I switched users to developer I was able to follow the process you outlined.

(venv) [root@devbox ~]
(venv) [root@devbox ~]# su - developer
[developer@devbox ~]$

Thanks again for the help!

It looks like you are having the same issue as Bill did (above post) change from root to user developer. HTH

(venv) [root@devbox ~]
(venv) [root@devbox ~]# su - developer
