docker buildx for multiarch support
create a builder
because the default builder doesn’t support multi-arch building,
create a new builder with docker-container driver and use it
1
| docker buildx create --use --name multiarch --driver docker-container
|
if your self-build registry is not https, please touch a buildkitd.toml

| [registry."your-registry-domain or ip"]
http = true
insecure = true

and then use this config to create a builder

| # if your builder has already existed, delete it and create
docker buildx rm multiarch
docker buildx create --use --name multiarch --driver docker-container --config ./buildkitd.toml

build the multiarch image and push it to your registry
docker buildx inspect --bootstrap to get the supported platform information
