<body><div>Same, and I have an example multi-stage docker file for building the image on Alpine for an example project: <a href="https://github.com/SpaceTime-IoT/presence-sample/blob/master/Dockerfile">https://github.com/SpaceTime-IoT/presence-sample/blob/master/Dockerfile</a> It also uses all the options relx supports to shrink the size of the tarball <a href="https://github.com/SpaceTime-IoT/presence-sample/blob/master/rebar.config#L26-L34">https://github.com/SpaceTime-IoT/presence-sample/blob/master/rebar.config#L26-L34</a><br></div>
<div><br></div>
<div>One feature relx doesn't yet support that may help a little with size of the unpacked release would be compressed applications (.ez). Pretty sure that is what reltool would do by default? Not sure how much it saves.<br></div>
<div> <br></div>
<div>Also, it is possible to use docker scratch* to have no real base image, but with Alpine being so small I don't think it saves enough to be worth it -- esp considering everything you then don't have, as Phil mentioned.<br></div>
<div><br></div>
<div>* And some hacks, copying over libs and a linker. Or a statically linked Erlang? Never done it with a statically linked Erlang, would that work with SSL?<br></div>

My application is a mix of Erlang and Elixir and runs in Docker containers. I use Alpine as the base and I get reasonably sized containers that don't have anything I don't need.<br></div>

I also want enough of a familiar environment (ls, ps, top, nslookup/dig, netstat) to troubleshoot issues. Alpine provides that without the other stuff that you don't need.<br></div>
