 # kibana-custom-nodejs-builds
-Contains configuration and sources to build node.js for custom platforms
+Contains configuration and sources to build node.js
+
+The main usecase right now is building `node.js@18+` with `[email protected]`, which is required for some older platforms. (More context: https://github.com/nodejs/unofficial-builds/pull/69)
+
+## Running locally
+You can run most scripts locally on Mac/Linux. You'll need a few of the build/infra tools:
+ - Docker
+ - node.js
+ - gsutil (`brew install google-cloud-sdk`)
+
+Export some env variables required for the builds
+```sh
+  export ARCH="arm64"
+  export TARGET_VERSION="18.16.1"
+```
+
+Then run individual scripts locally:
+```sh
+  ./scripts/create_build_images.sh
+  ./scripts/build_nodejs.sh
+```
+
+## Docker image for node.js builds
+One of the main components we need to create in this step is a docker image for an environment that's set up for building `node.js`.
+
+The bits for this component are in the [build-image-config](./build-image-config/) folder.
+
+The docker image uses mounted directories as working directories, as well as outputting the artifacts in these directories.
+
+
+## Scripts for running the builds
+Most of the `buildkite` logic is sheltered in the [scripts](./scripts/) directory.
+
+
+
+## Context
+During development, we found some more information that can be helpful as context, should anyone find this repo again
+
+ - This repository is only needed while
+   - centos:7 / RHEL7 is supported by Elastic, and we ship node.js with Kibana
+   - the unofficial-builds repo accepts a linux/arm64 build (https://github.com/nodejs/unofficial-builds/pull/83)
+ - The created Docker images needn't be pushed
+   - they can be used once for the build, then rebuilt in case we need to run it again
+ - I decided to remove the `VARIATION` attribute on the node.js:
+   - build would result in the variation showing up in the file and folder names, making the logistics more difficult, if we want to keep this mostly transparent for Kibana
