Docker detection is broken on Mac OS X
Opened this issue · 4 comments
I have Docker Intel Mac installed (Docker Desktop 4.28.0 (139021) ) and the latest func (main@09537e382daa74fb58ffc11d7aa0929cd2729bd4) complains about DOCKER_HOST not being found
% func build
Building function image
Error: cannot create docker client: docker/podman API not available
Possible causes:
The docker/podman daemon is not running.
The DOCKER_HOST environment variable is not set.
It looks like Docker for Mac now supports different context
% docker context ls
NAME TYPE DESCRIPTION DOCKER ENDPOINT KUBERNETES ENDPOINT ORCHESTRATOR
default moby Current DOCKER_HOST based configuration unix:///var/run/docker.sock
desktop-linux * moby Docker Desktop unix:///Users/dprotasowski/.docker/run/docker.sock
orbstack moby OrbStack unix:///Users/dprotasowski/.orbstack/run/docker.sock
I don't believe I added desktop-linux context - I'm assuming it came from upgrading Docker Desktop
I was under the impression you're attempting to use the "host" builder? If so, then the default builder is still either Pack or S2I, so you'll need to either explicitly choose the builder with --builder=host, or set the environment variable FUNC_BUILDER=host, or set a global default in ~.config/func/config.yaml of builder: host
Leaving this open, however, since this needs validation as a bug for those builders
Hello, I hope it is appropriate to post this here. I seem to have the same issue on Linux:

Same error as above:
% kn func build
A registry for function images is required. For example, 'docker.io/tigerteam'.
? Registry for function images: docker.io/tigerteam
Note: building a function the first time will take longer than subsequent builds
Building function image
Error: cannot create docker client: docker/podman API not available
Possible causes:

Tried choosing --builder=host per above:
% kn func build --builder=host

Tried setting DOCKER_HOST; not sure if relevant, but it seems strange that it says dial unix /var/run/docker.sock after pointing DOCKER_HOST to the Docker Desktop daemon?
% export DOCKER_HOST=unix:///home/vpsx/.docker/desktop/docker.sock
% kn func build

Still building
Still building
Yes, still building
Don't give up on me

Many thanks in advance for any help.
I had the same issue. I am trying Rancher desktop. Someone on another issue for another project found the solution:
docker context list --format json
export DOCKER_HOST=unix:///Users/stevef/.rd/docker.sock
func build
The value to set in DOCKER_HOST is found from the 1st command above
