Issue/Introduction

Whenever rebooting the cloud proxy nodes, user has to edit the file /etc/docker/daemon.json to restore certain configurations for the TCA management pack to function correctly after the reboot.

Specifically, you need to update the following setting: "insecure-registries": [#############.###.##########.###:8043"].

Now, when attempting to apply these updates after rebooting the CP nodes, you encounter the following error:

"Job for docker.service failed because the control process exited with error code."

See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.

Environment

VMware Aria Operations: 8.18.3

VMware Aria Operations Management Pack for TCA: 1.0.0

TCA: 3.1.1

TCP Bundle: 4.0

 

Cause

While updating the configuration file (daemon.json), a comma was unknowingly missed, which caused the VMware Aria Operations management pack for TCA to stop functioning and prevented configuration after the upgrade to VMware Aria Operations version 8.18.3.

Resolution

Update Cloud Proxy daemon.json file

• Make sure to add the above REPO to the daemon.json on the Cloud Proxys a line for "insecure-registries".
  
  - Log into the Cloud Proxy via SSH as root
  - vi /etc/docker/daemon.json
  - Add the "insecure-registries" entry as shown below to all Cloud Proxies.

Example file:

{
"iptables": true,
"log-opts": {"max-size": "200m", "max-file": "1"},
"log-level": "info" ,
"live-restore": true,
"no-new-privileges": true,
"icc": false,
"insecure-registries" :[ "#############.###.##########.###:8043" ]
}
