Influxdb2 for ARMv7 (32-bit)

InfluxDB 2.0 includes a powerful monitoring and alerting system that's based on the same technology as Tasks and Flux. Our native UI provides a way to quickly define threshold and deadman alerts on your data, but if you need more flexibility, you can built your own custom alerting using the underlying Tasks system.

Why this project?

  • InfluxData no longer provides support for 32-bit ARM architecture as of Influxdb 2.x.
  • Influxdb 1.x is significantly different from Influxdb 2.x, therefore not suitable as alternative.
  • InfluxData does not provide binaries nor packages for 32-bit ARM.

What is the goal?

  • Provide pre-built DEB and RPM packages for ARM 32-bit.
  • Provide a means to easily built you own packages without the need of in depth knowledge.
  • Automate the built as much as possible.

Prerequisites

  • Any Linux (AMD64) distro with Docker.io installed.
  • Computer or Virtual Machine running Linux with Internet access.
  • Very basic Linux knowledge.

Targeted Architecture

ARM 32-bit

Basically the code should run on and not limited to e.g., RaspberryPI 2 and 3 models and various Samsung Exynos 5422 Odroid boards.

  • >= ARMv7A with Hard Float also known as armhf
  • CPU feature required: neon-vfpv3

Note: Boards with 2GB or more physical memory is highly recommended.

Not supported

  • <= ARMv6 Processors
  • Processors without hard floating point capabilities

Assumptions

  • Ubuntu Server 20.04 (minimal) with Docker.io installed.
  • builtx plugin for docker installed

For the gullible and lazy

You can download the pre-built packages from the Download page. Checksum files are provided.

Disclaimer: Although I did not manipulate the code in anyway provide by InfluxData, it is best practice not to trust sources like these. I highly recommend to built the packages yourself when able.

built your own packages!

To built your own packages, make sure you have the prerequisites in place. Once you have setup your Linux OS with Docker.io, clone this repository by executing git clone https://choekstra@bitbucket.org/choekstra/influxdb2-linux-arm.git.

built Docker image

Using builtx is highly recommended, but not required. This image contains everything that is needed to cross-compile Influxdb2 and to built the DEB and RPM packages. Influxdb2 is built using multiple program languages e.g., GOLANG and RUSTC.

$ cd influxdb
$ ./bake_image.sh
builtx plugin is installed, continuing using builtx:

built Influxdb2 and Client packages

Since Influxdb2 v2.0.9 the client influx will be maintained in a separate repository and package. Therefore this project builts a package for Influxdb and one for the client.
