From the logs posted here, it seems that the WSL2 cannot access the internet - can't find https://storage.googleapis.com/skaffold/releases/latest/VERSION or https://index.docker.io/v2. The error messages from the debug logs show that during the docker build, docker was not able to pull down the golang:1.18 image from the Docker registry. Can you verify that the WSL2 has access to the internet and can pull images using docker pull? If I understand correctly, this is not working because the environment cannot access the internet to pull down deps one of your images needs

kwsorensen commented 1 year ago

docker pull golang:1.18 works inside wsl2. Posting my /etc/resolv.conf. After that I get the error:

listing files: parsing ONBUILD instructions: retrieving image "alpine:3": Get "https://index.docker.io/v2/": dial tcp: lookup index.docker.io: i/o timeout

after doing a docker pull alpine:3 skaffold dev appears to work. Not sure why only networking inside of skaffold dev fails. I am posting my resolv.conf for informational purposes.

# /etc/resolv.conf
nameserver 8.8.8.8

Glad you were able to get things working by manually pulling images. I will leave this open to see if anyone else encounters this, not sure currently why docker would be able to pull but skaffold couldn't

aaron-prindle commented 1 year ago

Going to close this for now as no other users seem to have encountered this, feel free to comment and I will re-open this you think this is an issue with Skaffold or if anyone else encounters this

Hi @aaron-prindle , currently facing the same issue with the same setup as @kwsorensen. The solution mentioned above seems to fix it, i.e. pull the images and then run the commands, in my case I used the skaffold build -vdebug command with the following skaffold.yaml

apiVersion: skaffold/v4beta1
kind: Config
metadata:
  name: hello-world-go
build:
  tagPolicy:
    gitCommit:
      ignoreChanges: true
  artifacts:
    - image: my-example/hello-world-go
 deploy:
    ...
