Knative支持arm64吗？

Question

我已经在arm64的k8s集群中运行了knative image，但是knative无法启动，它的日志如下：standard_init_linux.go:211: exec user process caused "exec format error"

我想知道是不是可以支撑手臂。

Answer 1

我已经能够使用Knative Serving Releases上发布的映像在运行ARM64 Ref的RaspberryPi上成功安装Knative Serving

如果你想知道一个特定的图像，可以使用crane

crane manifest gcr.io/knative-releases/knative.dev/serving/cmd/activator@sha256:f1e3e516a26ec07fbbbcefcce7619c74dd3b9ee943a5041a7f35c3f848964c0c

您可以确认镜像是否已经支持多拱门。在本例中，已经为ARM设置了Knative激活器镜像。
