有没有办法使用docker中的buildx构建命令创建多个标签？

Question

我正在尝试使用该docker buildx build命令，并且希望能够在一行中创建多个标签。我尝试过的一个例子

docker buildx build . \
    --platform linux/arm64,linux/amd64 \
    --no-cache --push \
    -t test:latest -t test:${CI_COMMIT_SHORT_SHA}

我已经看到这个问题，但我无法让它工作 https://github.com/docker/buildx/issues/396

-t它的工作原理与您发布的多个参数完全相同，例如-t repo1:tag1 -t repo2:tag2：

$ regctl tag ls sudobmitch/demo
alpine
regcli-test
regctl
ubuntu

$ docker buildx build -f build/Dockerfile.regctl.buildkit -t sudobmitch/demo:regctl1 -t sudobmitch/demo:regctl2 --push .

这是假设test你的问题中的一个例子。如果您确实尝试推送到test存储库，它会扩展到 Docker Hub 的库，以及其他官方映像，例如alpine、busybox、debian等。您无权推送到那里，因此请确保指向您有权访问的存储库推送图片并已登录。
