Unable to build the docker image with skaffold dev

[Shiv Shankar]

Hi,

I am getting an error when I left skaffold to create docker image on docker dev. Am I doing wrong?

Here is error

WARN[0001] run: build step: running build: COPY failed: stat /var/lib/docker/tmp/docker-builder168298683/target/hola-demo-0.0.1-SNAPSHOT.jar: no such file or directory 

ERRO[0002] run: running skaffold steps: running watch: adding deps for artifact: getting dockerfile dependencies: expanding dockerfile paths: getting file info: stat target/hola-demo-0.0.1-SNAPSHOT.jar: no such file or directory 

Dockerfile:

FROM openjdk:8-jre-alpine

COPY ./target/hola-demo-0.0.1-SNAPSHOT.jar /usr/src/hola/

WORKDIR /usr/src/hola

EXPOSE 8080

CMD ["java", "-jar", "/usr/src/hola/hola-demo-0.0.1-SNAPSHOT.jar"]

skaffold.yaml :

apiVersion: skaffold/v1alpha1

kind: Config

build:

  artifacts:

  - imageName: example.com/hola-demo

    workspace: .

  local: {}

deploy:

  kubectl:

    manifests:

    - paths:

      - k8s-*.yaml

      parameters:

        IMAGE_NAME: example.com/hola-demo

Any help??

I am running into the exact same problem. Using docker for desktop on a mac and am using nearly the same skaffold config as the original poster. Why is skaffold trying to copy files from a non-existent /var/lib/docker/tmp directory instead of my current working directory?

I was able to resolve my problem by manually building my app's docker image locally first. Afterwards, I can run skaffold dev and the build phase moves past the copy error and finishes building the image.
