The reserve forward promtail is the agent based on loki promtail with reserve forward server and client, responsible for gathering logs and sending them to Loki.

To build Promtail on non-Linux platforms, use the following command:

$ go build ./cmd/promtail

On Linux, Promtail requires the systemd headers to be installed for Journal support.

With Journal support on Ubuntu, run with the following commands:

$ sudo apt install -y libsystemd-dev
$ CGO_ENABLED=1 go build ./cmd/promtail

With Journal support on CentOS, run with the following commands:

$ sudo yum install -y systemd-devel
$ CGO_ENABLED=1 go build ./cmd/promtail

Otherwise, to build Promtail without Journal support, run go build with CGO disabled:

$ CGO_ENABLED=0 go build ./cmd/promtail
