Build docker images for aarch64

[jzbor]

Hi, I wanted to self-host monkeytype on my aarch64 server, but sadly the images do not seem to be available for aarch64. This should not be too difficult, given the images are built via Github actions anyway.

i'll have a look if we can build for linux/arm64

hi @jzbor,

i cannot test the images myself, can you give it a try?

use the docker-compose.yml from the SELF_HOSTING documentation and replace
monkeytype/monkeytype-frontend:latest with fehmer/mt-frontend:latest and monkeytype/monkeytype-backend:latest with fehmer/mt-backend:latest.

Thanks.

Thanks a lot. I can confirm that your image works!
