I have been running docker with k3d directly for use with skaffold but was hoping RD could drop in as a replacement for better cross platform support
f
The images should be visible to Kubernetes if you are using moby. One common pitfall is that if you use the 
latest
tag on the image, then you need to explicitly specify an 
imagePullPolicy
of 
IfNotPresent
or 
Never
because the default for the 
latest
tag is 
Always
, which will try to download the image from DockerHub even if it already exists locally. https://kubernetes.io/docs/concepts/containers/images/#image-pull-policy
• if you omit the 
imagePullPolicy
field, and the tag for the container image is 
:latest
, 
imagePullPolicy
is automatically set to `Always`;
h
Hey I appreciate your response! I think im missing something. I tried running with the image pull policy as you describe but it doesn't see the container and if i do
Copy code
rdctl shell docker images
i don't see the image in that registry. I tried disabling build kit too but didn't seem to work. im using the rancher expressapp from https://github.com/rancher-sandbox/docs.rancherdesktop.io currently running something like this

sorry that is a little gross without coloring. Idk if you have any ideas but im happy to provide any other info. I do see a local docker socker in 
~/.rd/docker.sock
in not 100% how this should work but with something like minikube i would need the DOCKER_HOST set or something to use the docker on the host? should the images be mounted into the vm or something?
f
Do you have another docker daemon running on your machine? What is the output of 
docker context ls
?
The fact that you get different output from 
docker images
vs 
rdctl shell docker images
would indicate that you are talking to a different docker socket on the host
h
oh man i think you nailed it
f
Use 
docker context use rancher-desktop
to switch if you are using a different daemon on the host.
h
im rebuilding with --context rancher-desktop now
f
But it would be best to run only a single one
h
yup!
thank you so much!
f
You are welcome!
h
i see the image with

f
That explains why Kubernetes couldn't see it
h
makes perfect sense! i didn't check that and it was making me doubt my understanding haha
thanks again
