ARM docker Image

[vncloudsco]

Dear: all contributors

we know that your software already support ARM however i see its docker image is not updated. is there any guide to help me do it or can you update the docker hub image?

multi arch images would be great! its possible to setup easily with github actions

it's been more than a year since this, just to know are there any update or hope for those with ARM?

Thank you before hand!

You'll want to ping the team about #397, the re-opened flavor of the PR linked to this issue above. I no longer work for Zulip and highly doubt I'll have the appropriate time to do much with that PR as an external contributor any time soon, but it appears there's not a whole lot of feedback on it to address before it'll be in a merge-ready state (to my eye, and with the understanding that my knowledge of the Zulip codebase context ends at the end of March when I changed dayjobs).

Are there any updates on this? Would be great to be able to run on t4g instances on AWS!

Any updates? :) Would be great to get this installed on an ARM VPS! 😄

For anyone who cannot wait (like me), simply build the image yourself on the target machine. For this, navigate to the folder to which you cloned docker-zulip:

$ pwd
/home/dummy-user/docker-zulip
$ # this can take several minutes - in my case it was ~50 min on a relatively new server
$ # you can choose (almost) any tag you like after -t
$ docker buildx build -t zulip-arm:latest .

Now edit the docker-compose.yml with your favourite editor or vim:

$ vim docker-compose.yml

Change the image of zulip from zulip/docker-zulip:<version> to the tag you chose earlier (zulip-arm:latest in this case).

You can probably also do this in one step changing image to build in the docker compose file. You will find more information about this in the official docker documentation.

You can also cross-build from either architecture to the other. This is what the build_and_push_image.sh from #397 does: builds ARM64 images from AMD64 hosts. That script was designed to be able to push to ~any registry for ~any architectures or tags by changing environment variables.

The branch is a year and a half old and at this point I don't know what kind of rebase pain someone would be in for to stack it onto current trunk, but I suspect at least that script could be cherry-picked and used by anyone interested, still.
