hagrid 0.1.9 fails at starting a node on a Raspberry Pi

[Rene36]

Description

After running hagrid launch local_node domain on a Raspberry Pi 4 with an ARM architecture the docker build fails at the tailscale container. Tailscale is responsible for setting up a VPN service. It gives the following error:

How to Reproduce

1. Run hagrid launch local_node domain on a Raspberry Pi 4 (with 64bit version of Ubuntu)

Expected Behavior

If you run hagrid launch local_node domain on a Raspberry Pi 4 (with 64bit version of Ubuntu) it should start a domain node.

System Information

• OS: Ubuntu 64bit
• OS Version: 20.10
• Language Version: Python 3.8.10
• Package Manager Version: Pip 21.3.1

Additional Context

• uname -m gives an aarch64 architecture.
• Tailscale is available for Raspberry Pis (see here at the bottom).
• The docker file used in hagrid is using FROM shaynesweeney/tailscale:latest as its base image link, which uses FROM golang:1.17-alpine AS build-env as its base image link.
• The image golang:1.17-alpine supports linux/arm64/v8 link
• See below the output of hagrid debug

Hi @Rene36 , could you try with the latest 0.6.0 branch and post regarding the status of the error.

[Rene36]

With some workarounds I fixed the issue for a fresh Ubuntu 20.04 install, PySyft v0.6.0 and hagrid v0.2.0. I fixed the CPU architecture issue by changing two dockerfiles. I tried the setup with two jupyter notebooks and I can connect to the domain node on the Raspberry Pi. However, I did not improve for efficiency.

1. Find the path of the installed hagrid package.
2. Open lib.py and comment out update_repo(repo=GIT_REPO, branch=repo_branch) to avoid that our changes to the dockerfiles are over written.

The used tailscale image (shaynesweeney/tailscale:latest) in /hagrid/PySyft/packages/grid/vpn/tailscale.dockerfile and the waitforit function in hagrid/PySyft/packages/grid/backend/backend.dockerfile do not support ARM 64 bit (aarch64). Therefore, I replaced it with the original tailscale image and built the waitforit function from source.
The resulting dockerfiles are at the bottom of this post.

The last release from waitforit is almost 4 years old. Therefore, I recommend to replace it with something more current.

I logged into the remote Raspberry Pi domain via

domain = sy.login(email="info@openmined.org",
                              password="changethis",
                              url=<ip_address>,
                              port=8081)

Hi @Rene36 we have actually added support for arm64 linux just recently and it runs in CI on our nightlies. HAGrid now supports an extra command --platform linux/arm64 which will get passed to docker. Can you confirm if this works on Raspberry Pi?

Also please make sure to update to the latest 0.7.0 beta releases.

$ pip install hagrid
$ hagrid launch domain to docker:8081 --tag=latest --platform=linux/arm64

[madhavajay]

I am closing this due to no response. arm64 linux builds have been available for a while now and are tested in CI.
