Upgrade advice - upgrade from aarch64 to ARM64 image

[Talisker]

I'm currently on version 26011. I understand that the aarch64 image is no longer supported. So, I therefore need to update to the ARM64 image. Can anyone possibly suggest how I update my docker compose.yaml file (see below). Ideally I'd like to keep my existing reactions etc. rather than start from scratch.

# Multi-System Reactor template docker-compose.yml (version 22160)
#
# Change the lines indicated by "DO"...
#
services:
  reactor:
    container_name: reactor
    environment:
      # DO change the TZ: line to set your local time zone.
      # See valid TZ list: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
      TZ: GB 
      #
      # DO NOT change this path. Your directory location is in "source" below.
      REACTOR_DATA_PREFIX: /var/reactor

    # DO change the image below to the one you are using (e.g. armv7l or aarch64 for RPi 4)
    image: toggledbits/reactor:latest-aarch64

    restart: "always"
    expose:
      - 8111
    ports:
      - 8111:8111
    volumes:
        # DO change the /home/username/reactor below to the directory you created for
        # your local data; DO NOT change the /var/reactor part
      - /home/pi/docker/reactor:/var/reactor
      - /etc/localtime:/etc/localtime:ro
    tmpfs: /tmp

There's information in this earlier post to help you confirm that your OS is 64-bit capable (or not). Take a look at that first. You can report here what the DEB_HOST_ARCH value is.

So, in response to 'sudo dpkg-architecture -q DEB_HOST_ARCH' I get the following which I think is positive in that it confirms a 64bit architecture (I think):

/home/pi/docker/reactor$ sudo dpkg-architecture -q DEB_HOST_ARCH
arm64

In that case, once I have done a back-up, is it simply the case that I replace the following:

    # DO change the image below to the one you are using (e.g. armv7l or aarch64 for RPi 4)
    image: toggledbits/reactor:latest-aarch64

with:

# DO change the image below to the one you are using (e.g. armv7l or aarch64 for RPi 4)
image: toggledbits/reactor:latest-arm64

What is confusing me a little is that the exemplar docker compose .yaml 'volumes:' file structure is a bit different to my current .yaml file. Will this cause a problem?

Thanks.

The change in the newer file will be significant later, but no need to worry about it today. Make as few changes as possible. The only change you need to make here is from latest-aarch64 to latest-arm64.
