Install on Amazon Linux

Calyptia Fluent Bit is distributed as fluent-bit package and is available for the latest Amazon Linux 2 and Amazon Linux 2022. The following architectures are supported

• x86_64

• aarch64 / arm64v8

Single line install

A simple installation script is provided to be used for most Linux targets. This will always install the most recent version released.

curl https://raw.githubusercontent.com/fluent/fluent-bit/master/install.sh | sh

This is purely a convenience helper and should always be validated prior to use. The recommended secure deployment approach is to follow the instructions below.

Amazon Linux 2022

For Amazon Linux 2022, until it is GA, we need to force it to use the 2022 releasever in Yum but only for the Calyptia Fluent Bit repository.

export FLUENT_BIT_INSTALL_COMMAND_PREFIX="sed -i 's|\$releasever/|2022/|g' /etc/yum.repos.d/fluent-bit.repo"
curl https://raw.githubusercontent.com/fluent/fluent-bit/master/install.sh | sh

Configure Yum

We provide fluent-bit through a Yum repository. In order to add the repository reference to your system, please add a new file called fluent-bit.repo in /etc/yum.repos.d/ with the following content:

Amazon Linux 2

[fluent-bit]
name = Fluent Bit
baseurl = https://packages.fluentbit.io/amazonlinux/2/$basearch/
gpgcheck=1
gpgkey=https://packages.fluentbit.io/fluentbit.key
enabled=1

Amazon Linux 2022

[fluent-bit]
name = Fluent Bit
baseurl = https://packages.fluentbit.io/amazonlinux/2022/$basearch/

Note: we encourage you always enable the gpgcheck for security reasons. All our packages are signed.

Install

Once your repository is configured, run the following command to install it:

yum install fluent-bit

Now the following step is to instruct systemd to enable the service:

sudo service fluent-bit start

If you do a status check, you should see a similar output like this:

$ service fluent-bit status
Redirecting to /bin/systemctl status  fluent-bit.service
