## Multi-arch support - You maybe need to run this command to get buildx if you get this error erro: ``` exec /bin/sh: exec format error ``` fixing command: ```bash docker run --rm --privileged docker/binfmt:a7996909642ee92942dcd6cff44b9b95f08dad64 ``` i have no idea what it does, but it seems to fix the thing ._. - You MAY also need to set these variable before running build, depending on the docker version on host ```bash export COMPOSE_DOCKER_CLI_BUILD=1 export DOCKER_BUILDKIT=1 ``` Enable (1) or disable (0) BuildKit builds #### Building new container - `cd` into a folder and run ```bash docker compose build ```
