如何将docker build的架构设置为arm64？

我有一个Dockerfile，我在amd64上运行，但是想在arm64上运行。 由于go build工具以GOARCH = arm64作为参数，所以我不需要任何其他交叉编译工具来制作二进制文件。

# Run the build FROM mojlighetsministeriet/go-polymer-faster-build ENV WORKDIR /go/src/github.com/mojlighetsministeriet/email COPY . $WORKDIR WORKDIR $WORKDIR RUN go get -t -v ./... RUN CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build # Create the final docker image FROM scratch COPY --from=0 /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt COPY --from=0 /go/src/github.com/mojlighetsministeriet/email/email / ENTRYPOINT ["/email"] 

问题是生成的图像被标记为错误的架构amd64而不是arm64。 如何将一个parameter passing给docker build以便将架构设置为arm64？

 $ docker image inspect mojlighetsministeriet/email-arm64 [ { "Id": "sha256:33bcd7da8631c7a0829d61cc53479a26ab7f31fab1cb039105de415ddc6178f3", "RepoTags": [ "mojlighetsministeriet/email-arm64:latest" ], "RepoDigests": [ "mojlighetsministeriet/email-arm64@sha256:ab3f05d5597c3a304953b5c14f795179aa75bdfd458af3dc3cfb8b8d8eb87bc3" ], "Parent": "sha256:e5888262d93ea0946b5fd8146cf1c19ec3a7bac4d36eb51848ef0aefa75cf8e7", "Comment": "", "Created": "2017-12-05T18:36:36.273648787Z", "Container": "7a226edb3b52aaeeefec9e0fb4dd1da50d84992fb6cc374aeda9d82eec1bb2c8", "ContainerConfig": { "Hostname": "7a226edb3b52", "Domainname": "", "User": "", "AttachStdin": false, "AttachStdout": false, "AttachStderr": false, "Tty": false, "OpenStdin": false, "StdinOnce": false, "Env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" ], "Cmd": [ "/bin/sh", "-c", "#(nop) ", "ENTRYPOINT [\"/email\"]" ], "Image": "sha256:e5888262d93ea0946b5fd8146cf1c19ec3a7bac4d36eb51848ef0aefa75cf8e7", "Volumes": null, "WorkingDir": "", "Entrypoint": [ "/email" ], "OnBuild": null, "Labels": {} }, "DockerVersion": "17.10.0-ce", "Author": "", "Config": { "Hostname": "", "Domainname": "", "User": "", "AttachStdin": false, "AttachStdout": false, "AttachStderr": false, "Tty": false, "OpenStdin": false, "StdinOnce": false, "Env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" ], "Cmd": null, "Image": "sha256:e5888262d93ea0946b5fd8146cf1c19ec3a7bac4d36eb51848ef0aefa75cf8e7", "Volumes": null, "WorkingDir": "", "Entrypoint": [ "/email" ], "OnBuild": null, "Labels": null }, "Architecture": "amd64", "Os": "linux", "Size": 7861466, "VirtualSize": 7861466, "GraphDriver": { "Data": { "LowerDir": "/var/lib/docker/overlay2/03cb0162bf922636e4e0ec90123b81565a447c6cd511741103551d2f0e7f09f9/diff", "MergedDir": "/var/lib/docker/overlay2/091f74815a0caf457df7e57ade43b41c4dd8551388beca44815a7038501742ee/merged", "UpperDir": "/var/lib/docker/overlay2/091f74815a0caf457df7e57ade43b41c4dd8551388beca44815a7038501742ee/diff", "WorkDir": "/var/lib/docker/overlay2/091f74815a0caf457df7e57ade43b41c4dd8551388beca44815a7038501742ee/work" }, "Name": "overlay2" }, "RootFS": { "Type": "layers", "Layers": [ "sha256:66f615d03920919b0fa8bc9fed45515bb95636be1837fdd10a82b2c183e2ad5b", "sha256:bd6a01b885eb6e3eec38a3fe3a2899646509633730b210cf6987456fd40b8a1c" ] }, "Metadata": { "LastTagTime": "2017-12-14T10:24:10.796813522+01:00" } } ]
