Error deploying with docker on arm64 system

[vitorestevamia]

I'm trying to deploy the agent on a raspberrypi 4 (arm64v8 system) with docker but he image's platform is amd64 only. I did not found any variation of the image for this system. Is there any different image i can use or a way to build my own?

docker compose file:

version: "3.5"

services:
  agent:
    image: bcgovimages/aries-cloudagent:py36-1.16-1_0.7.5

    container_name: agent-${AGENT_NAME}
    environment:
      ACAPY_ENDPOINT: "${ENDPOINT}:${AGENT_PORT}"
      ACAPY_LABEL: "${AGENT_NAME}"

      ACAPY_ADMIN_INSECURE_MODE: "true"
      ACAPY_AUTO_PROVISION: "true"
      ACAPY_LOG_LEVEL: "info"

      ACAPY_GENESIS_URL: "http://dev.bcovrin.vonx.io/genesis"
      ACAPY_WALLET_TYPE: "indy"
      ACAPY_WALLET_SEED: "${WALLET_SEED}"
      ACAPY_WALLET_NAME: "wallet${AGENT_NAME}"
      ACAPY_WALLET_KEY: "walletkey"

    entrypoint: /bin/bash
    command: ["-c",
        "aca-py start \
        --inbound-transport http '0.0.0.0' ${AGENT_PORT} \
        --outbound-transport http \
        --admin '0.0.0.0' ${ADMIN_PORT}"
    ]
    ports:
      - "${ADMIN_PORT}:${ADMIN_PORT}"
      - "${AGENT_PORT}:${AGENT_PORT}"

terminal output:

Here is a comment @PatStLouis made on the Hyperledger Discord #aries-embedded channel:

I had great success running aca-py on a raspberry pi in a docker container using QUS https://dbhi.github.io/qus/ You can even setup a fleet on balena cloud (max 10 agents in the free tier) and expose the agent inbound port https://www.balena.io/cloud

We will be publishing multiarchitecture images that will have support for ARM. We are currently working though some dependency issues related to this; https://github.com/hyperledger/aries-cloudagent-python/issues/2124

[vitorestevamia]

Nice, i'll run some tests using QUS! Thank you @WadeBarnes and @PatStLouis for sharing this ;)

Do you have any idea of when the multiarchitecture images will come out?

[WadeBarnes]

The multiarchitecture images will be available as soon as the askar dependencies publish the supporting binaries. In most cases I think it's just a matter of bumping the version defined in aca-py. The bbs dependency may lag behind a bit, but I don't think it's a blocker for many use cases.

[vitorestevamia]

About using QUS, this emulator based on it worked pretty well in my case and it's very straightforward to use https://github.com/tonistiigi/binfmt

For anyone having this problem, you just need to:

1. Emulate amd64

   docker run --privileged --rm tonistiigi/binfmt --install amd64

2. Add platform field on your docker-compose service and set it to linux/amd64

   services:
   agent:
   platform: linux/amd64
   image: bcgovimages/aries-cloudagent:py36-1.16-1_0.7.5
   ...

3. Run it :D

   docker compose up

   Thank you @WadeBarnes for the fast and effective help.

Hi there, am I right in guessing, that there still isn't (official) support for arm64?
