This repo holds the Dockerfile and build scripts to build docker images which are used to build EMQX.
The docker images are also pulled by a few other Erlang repos in the CI builds.
https://github.com/emqx/erlang-rocksdb https://github.com/emqx/quic https://github.com/emqx/emqtt
OTP repo https://github.com/emqx/otp.git
EMQX uses a forked Erlang/OTP with the tag scheme <UPSTREAM_TAG>-N
where N is the build number which includes bug fixes to Erlang/OTP source code.
For example: OTP-24.1.5-1
ghcr.io/emqx/emqx-builder/<BUILDER_GIT_TAG>:1.13.1-24.1.5-1-ubuntu20.04
Where BUILDER_GIT_TAG is of scheme 4.4-1 for images to build EMQX
4.4.X and 5.0-1, 5.0-2 for images to build EMQX 5.0.X. 1.13.1 and
24.1.5-1 are the Elixir and OTP version, respectively.
Note that starting from 5.2, we no longer track EMQX versions in the image tag scheme.
i.e. emqx-builder:5.2 does not mean it's only intended to build EMQX 5.2.
