my kubernetes is based on arm,with kubernetes1.22.4

my faas-cli command:

faas-cli build -f ./add.yml

the response code :

[0] > Building add.

then can someone tell me the currect way to build a function with arm in openfaas,and why this happened,did i do someting wrong?

  • Your target platform is amd64 which I don't believe is compatible with ARM processor that your workers are running. – lance.johnsn Jan 10 '22 at 20:19
  • yes，you are right. So i tried a another way with docker buildx. the command is :DOCKER_BUILDKIT=1 faas-cli build -f function.yml --no-cache --build-arg platform=linux/arm64/v8 – lunatic-myw Jan 12 '22 at 04:35
  • But could you tell me why it works? – lunatic-myw Jan 12 '22 at 04:35
  • The instruction sets are different between the two platforms. Your workers are ARM processors. As a result the executables, built for one platform, do not work on the other. Your argument specifying the platform ensures the executables match the processor on the workers. – lance.johnsn Jan 19 '22 at 18:13
  • Running into the same issues as the OP. What should one set their build flag.. these do not seem to fix the running containers: `buildplatform=arm64 buildarch=arm64 targetos=linux targetarch=amd64` – Cmag Dec 12 '22 at 03:55
