Skaffold: Skaffold fails to push to local private docker registry

[raul1991]

I ran a local docker registry and would want to use it with skaffold so it can push images to it but it fails.

Expected behavior

It should be able to push to the local registry

Actual behavior

This fails with the error

Get http://localhost:5000/v2/: dial tcp 127.0.0.1:5000: connect: connection refused

Information

• Skaffold version: 1.8.0
• Operating system: macos
• Contents of skaffold.yaml:

apiVersion: skaffold/v1beta15
kind: Config

  tagPolicy:
    envTemplate:
      template: "{{.IMAGE_NAME}}:v1.0.0"
  artifacts:
  - image: rest-api
    context: ./rest-api
  - image: grafana
    context: ./grafana
  - image: prometheus
    context: ./prometheus
  local:
    push: true
deploy:
  kubectl:
    manifests:
     - kustomizer/minikube/deployments/*.yaml
     - kustomizer/minikube/services/*.yaml
     - kustomizer/minikube/configmaps/*.yaml
     - kustomizer/minikube/volumes/pvc/*.yaml
     - kustomizer/minikube/volumes/pv/*.yaml

Steps to reproduce the behavior

1. Clone https://github.com/raul1991/whatsapptracker
2. docker run -d -p 5000:5000 --restart=always --name registry registry:2
3. skaffold dev --port-forward --default-repo=localhost:5000

It's not that simple, unfortunately. localhost is 127.0.0.1, which will refer to whichever host or container it is running on. It might work with --default-repo=$(ipconfig getifaddr en0) assuming the containers can reach your local host.

Since you seem to be using minikube, you can remove your local.push: true and Skaffold will automagically build and load images into the minikube's docker daemon.

You explanation was right.I was behind a proxy therefore the problem was occurring and fixing that made it all work fine.

Ok, That was bit hasty on my part to close this issue so reopening it so as to monitor it.

@rahulwa Is that ok to close this issue?

[rahulwa]

@dgageot I think you wrongly pinged me!

[raul1991]

Yeah we can close it for now.

@dgageot I am having same issue when i try to push image for the second time. Even if i use minikube, I need to push it to my private docker registry to be used by my peers.

~/my-project $ skaffold build -p dev
