pf9ctl Binary Incorrectly Updating Proxy Settings

Problem

While updating proxy settings with the pf9ctl binary, the /opt/pf9/hostagent/pf9-hostagent.env file is being updated incorrectly.

Environment

Platform9 Managed Kubernetes - v5.9 through v5.11
pf9ctl

Diagnosis

Before applying pf9ctl set-proxy the file /opt/pf9/hostagent/pf9-hostagent.env looks like below.

Bash
    
 
$ cat /opt/pf9/hostagent/pf9-hostagent.envPYTHONPATH="/opt/pf9/hostagent/lib/python3.6/site-packages:/opt/pf9/hostagent/lib/python3.9/site-packages/bbslave:${PYTHONPATH}"PYTHON_EGG_CACHE=/tmp/python-eggsLD_LIBRARY_PATH="/opt/pf9/python/pf9-lib:/opt/pf9/python/pf9-hostagent-lib:${LD_LIBRARY_PATH}"
Copy

Setup proxy settings with pf9ctl on Node.

pf9ctl command
    
xxxxxxxxxx
 
$ pf9ctl set-proxy --protocol http --host-ip [IP_ADDRESS_1] --port [PORT] --no-proxy [IP_ADDRESS_2],[IP_ADDRESS_3]
Copy

After applying pf9ctl set-proxy the file /opt/pf9/hostagent/pf9-hostagent.env looks like below.

Bash
    
 
$ cat /opt/pf9/hostagent/pf9-hostagent.envPYTHONPATH="/opt/pf9/hostagent/lib/python3.6/site-packages:/opt/pf9/hostagent/lib/python3.9/site-packages/bbslave:${PYTHONPATH}"PYTHON_EGG_CACHE=/tmp/python-eggsLD_LIBRARY_PATH="/opt/pf9/python/pf9-lib:/opt/pf9/python/pf9-hostagent-lib:${LD_LIBRARY_PATH}"export http_proxy=http://[IP_ADDRESS_1]:[PORT]export https_proxy=http://[IP_ADDRESS_1]:[PORT]export HTTP_PROXY=http://[IP_ADDRESS_1]:[PORT]export HTTPS_PROXY=http://[IP_ADDRESS_1]:[PORT]export no_proxy=localhost,127.0.0.1,::1,localhost.localdomain,localhost4,localhost6export NO_PROXY=localhost,127.0.0.1,::1,localhost.localdomain,localhost4,localhost6

Cause

This is due to a BUG: PMK-6577 and is resolved in PMK v5.12.

Workaround

Manually update /opt/pf9/hostagent/pf9-hostagent.env file with required environment variables.

Bash
    
 
$ cat /opt/pf9/hostagent/pf9-hostagent.envPYTHONPATH="/opt/pf9/hostagent/lib/python3.6/site-packages:/opt/pf9/hostagent/lib/python3.9/site-packages/bbslave:${PYTHONPATH}"PYTHON_EGG_CACHE=/tmp/python-eggsLD_LIBRARY_PATH="/opt/pf9/python/pf9-lib:/opt/pf9/python/pf9-hostagent-lib:${LD_LIBRARY_PATH}"http_proxy=http://[IP_ADDRESS_1]:[PORT]https_proxy=http://[IP_ADDRESS_1]:[PORT]HTTP_PROXY=http://[IP_ADDRESS_1]:[PORT]HTTPS_PROXY=http://[IP_ADDRESS_1]:[PORT]no_proxy=127.0.0.1,localhost,[IP_ADDRESS_2],[IP_ADDRESS_3]NO_PROXY=127.0.0.1,localhost,[IP_ADDRESS_2],[IP_ADDRESS_3]
Copy

Restart pf9-hostagent service.

Bash
    
xxxxxxxxxx
 
$ systemctl restart pf9-hostagent
Copy

Verify the proxy settings by fetching pod logs.

Kubectl Command
