Can't build image on raspberry pi4

[ashvants]

getting below error when trying to build on raspberry pi 4.

no matching manifest for linux/arm/v7 in the manifest list entries

Just ran into this same issue. When attempting to run on RPi4 using Docker for linux/arm64 I receive this output: standard_init_linux.go:211: exec user process caused "exec format error"

@jonmacchio Using @sameersbn image i have managed to get this rebuilt for armv7 now and got it running on pi4

[jonmacchio]

@ashvants Any advice on how to rebuild for arm architecture?

It is not straight forward build process., needs some level of debugging as well.
To run the builds on Docker for pi run the buildx command as below; BuilderName can be anything you want eg., TestBuilder

docker buildx create --name BuilderName
docker buildx use BuilderName

#Login to your container registry
docker login

#Build and push to your container repository
Docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 -t registry/repository --no-cache --push .

or if you want to skip the steps and try my build which is available on docker registry you can try running the

docker pull ashvants01/bind-testv1:latest

without user config

docker run --name bind -d --restart=always --publish 53:53/tcp --publish 53:53/udp --publish 10000:10000/tcp --volume ~/bind/srv/docker/bind:/data ashvants01/bind-testv1:latest

#with root user config
sudo docker run --name bind -d --restart=always --publish 53:53/udp --publish 10000:10000 --env='BIND_USER=root' --env='ROOT_PASSWORD=*****' --dns=127.0.0.1 --volume ~/bind/srv/docker/bind:/data ashvants01/bind-testv1:latest

@ashvants Was able to follow your steps and got bind working and successfully logged in to webmin! Thanks!!

It doesn't work for me. 😞

On the first run I got this errors:

After I changes the tag for the base image from ubuntu:focal-20200423 to ubuntu:focal it worked bestter but after some computing I got this error:

I ran the build on a Mac (macOS 10 with Docker Desktop 2.4.0.0 Engine 19.03.13) and an Linux machine (Ubuntu Bionic with Docker version 19.03.13, build 4484c46d9d) with exact the same results.
