Question

I m trying to build kolide launcher for linux First the <https github com kolide launcher blob master Dockerfile|dockerfile> doesn t work as I expected but with fews changes it builds the linux version I ve changed ~`RUN GO111MODULE=on go run cmd make make go targets=launcher extension linkstamp $FAKE`~ with this `RUN GO111MODULE=on go run cmd make make go targets=launcher osquery extension exe linkstamp $FAKE` and ~`RUN cp build linux usr local kolide bin `~ with this `RUN cp build linux amd64 usr local kolide bin ` I ve taken a look at kolide fpm but I don t understand very well how it works What should I do if I want a simple rpm to deploy to hosts and how can I configure the launcher I d like to build an rpm package that it will be launched at the startup like the msi for windows

`kolide fpm` is used internally by package builder when it s building for rpm deb pacman It s not something you would call on your own

seph · Answer

The linux packaging has to run on a host that supports docker I use macOS linux would probably work windows might never tried windows and docker

seph · Answer

If you re packaging I would not recommend going near the dockerfile You re probably right that it has an error but it shouldn t matter

seph · Answer

So building launcher for linux woud generally be done via cross compiling the go `make build launcher linux` should work But I don t know if you re trying to build launcher or just a package

seph · Answer

If you re building a package invoke `package builder` with appropriate options from a host that supports docker

Thank you a lot for your help I think I have figured it out running this command `package builder make hostname=fleet 8080 enroll secret=my secret root pem=fleet pem output dir= targets linux launchd rpm` I have this error message `run command var folders z8 lhzyngpx57l42hr3qkq4fm1w0000gn T package packageRoot989424315 usr local launcher bin launcher version stderr= fork exec var folders z8 lhzyngpx57l42hr3qkq4fm1w0000gn T package packageRoot989424315 usr local launcher bin launcher exec format error` And the rpm output package is empty should I add package version flag which value should I give to have the most latest version By the way the docs is a little bit tricky to me Adding some other examples especially about cross compiling to the documentation can make it easier to understand

This is the file sharing settings in my docker

`pacakge builder` and to be honest much of the launcher tooling expects a fairly deeop knowledge of OS management and packaging If you need a lot of support or ready made things there are several commercial vendors

seph · Answer

Yes If you re cross packaging you need to specify the pacakge version I usually set it to whatever the stable launcher version is

Have you tried invoking `package builder make hostname=fleet 8080 enroll secret=my secret root pem=fleet pem`

Bacarus · Answer

Yes in that way I build the pkg installer I ve already made the pkg for mac os and the msi for windows and they work as expected By the way I ve found the error I used linux launchd rpm instead of linux systemd rpm and now it works Thank you for your help seph I m sorry for wasting your time I don t have a lot of experience and I m trying to learn

seph · Answer

You may find `package builder list targets` interesting

seph · Answer

If you re packaging on macOS you can specify multiple targets I would normally use ` targets darwin launchd pkg linux systemd rpm linux systemd deb` for example
