Upgrade the agent

To upgrade, run the same install command again. The installer replaces the binary, keeps your logcore.yaml and services/, and restarts the service.

Linux

bash -c "$(curl -fsSL https://logcore.lsofito.com/install.sh)"

Windows (Administrator)

iwr -useb https://logcore.lsofito.com/install.ps1 | iex

You don't need LOGCORE_API_KEY for an upgrade. If you pass it, the key in logcore.yaml is replaced.

Check the new version:

logcore-agent version
sudo logcore-agent status

What's kept

Item	On upgrade
logcore.yaml	kept (only api_key and apm.enabled change if you pass them)
services/*.yaml	kept
Read positions (registry.json)	kept, so no lines are lost or sent twice
The logcore-agent user and its ACLs	kept

Upgrade many servers

Run the command with your configuration management tool, for example Ansible:

- name: Upgrade Logcore agent
  ansible.builtin.shell: bash -c "$(curl -fsSL https://logcore.lsofito.com/install.sh)"
  become: true
