Newbie installing Influx2.0 on Raspberry Pi 3 Model B+: "exec format error"

[mdurie]

Hi Influx Community!

I’m really excited to learn more about Influx and I want to test it on a new RBPi3 B+ with ARMv8 cpu.

I’m currently trying to install from Docker, using the current Influx 2.0 documentation.

This is my cli result:

pi@raspberrypi:~ $ docker run --name influxdb -p 9999:9999 quay.io/influxdb/influxdb:2.0.0-alpha
Unable to find image ‘quayio/influxdb/influxdb:2.0.0-alpha’ locally

Status: Downloaded newer image for quayio/influxdb/influxdb:2.0.0-alpha

Can anyone please assist on how to get around this?
Thanks a lot!
Maarten

Your OS is Armv7, not 8. This means it’s s 32 bit OS, and InfluxDB doesn’t support 32bit yet; though a PR was merged yesterday.

feat: enable 32-bit support for influxd

Can you compile from source until we get a release out, please?

We’d love your feedback

[mdurie]

Thanks for the feedback! I was surprised to indeed see ARMv7. I just bought the Raspberry with the image on the back of the box. It seems that Raspbian is not yet updated?

I’m trying to figure out how to build a docker image from the Github repo and will get back to it.

[rawkode]

You need to build the binary go build ./cmd/influxd

You should then be able to use docker image build -f ./docker/influxd/Dockerfile .

[mdurie]

Ok, it took me longer then expected.
I had to install Go v1.13.4 (minimal v1.12 required) and Bazaar.

I was able to compile from the source.
But now I’m getting stuck on building the Docker image:

pi@raspberrypi:~/influxdb $ docker image build -f ./docker/influxd/Dockerfile .
Sending build context to Docker daemon    271MB
Step 1/8 : FROM debian:stable-slim
 ---> 54b5f788ca3c
Step 2/8 : COPY influx influxd /usr/bin/
COPY failed: stat /var/lib/docker/tmp/docker-builder842176580/influx: no such file or directory

It’s probably something stupid with the directory from where I’m doing this, but I haven’t figured it out yet.

[rawkode]

Ah, yes. The Dockerfile needs influx and influxd to exist.

Please run go build ./cmd/influx and then rerun your docker image build command.

[mdurie]

Well, rawkode, thanks for your assistance & patience here. It would simply not been possible without you…
Wauw, not sure how I did it, but I got Influx running now, only the CLI though:

I was able to build the docker image!
Then used the docker run command to start the container:
docker run --name myinflux2 -p 9999:9999 influx2

At this point, the localhost:9999 is giving a 500 Internal Server Error, even after waiting for a while for the server to properly boot.
From here, I can continue with the CLI setup, but that’s not my preference.

Am I missing something to get the UI setup going?
