The recommended secure deployment approach is to use the following instructions:
Server GPG key
The first step is to add the Fluent Bit server GPG key to your keyring to ensure you can get the correct signed packages.
Follow the official Debian wiki guidance.
sudo sh -c 'curl https://packages.fluentbit.io/fluentbit.key | gpg --dearmor > /usr/share/keyrings/fluentbit-keyring.gpg'Update your sources lists
For Debian, you must add the Fluent Bit APT server entry to your sources lists. Ensure codename is set to your specific Debian release name. (for example: bookworm for Debian 12).
codename=$(grep -oP '(?<=VERSION_CODENAME=).*' /etc/os-release 2>/dev/null || lsb_release -cs 2>/dev/null)Update your source's lists:
echo "deb [signed-by=/usr/share/keyrings/fluentbit-keyring.gpg] https://packages.fluentbit.io/debian/$codename $codename main" | sudo tee /etc/apt/sources.list.d/fluent-bit.listUpdate your repositories database
Update your system's apt database:
sudo apt-get updateInstall Fluent Bit
Ensure your GPG key is up to date.
Use the following
apt-getcommand to install the latest Fluent Bit:sudo apt-get install fluent-bitInstruct
systemdto enable the service:sudo systemctl start fluent-bit
If you do a status check, you should see a similar output similar to:
$ sudo service fluent-bit status
