unable to prepare context: unable to evaluate symlinks in Dockerfile path

[kjplunkett]

I was just following along with the tutorial here:
https://aws.amazon.com/blogs/opensource/github-actions-aws-fargate/

I seem to be running into an error on the build tag and push step, everything before is working. I have not pushed a new container image to ECR before so it could be something I don't understand about how that works but it appears the dockerfile does not exist?

console output for this step:

 # Build a docker container and
  # Build a docker container and
  # push it to ECR so that it can
  # be deployed to ECS.
  docker build -t $ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG .
  docker push $ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG
  echo "::set-output name=image::$ECR_REGISTRY/$ECR_REPOSITORY:$IMAGE_TAG"
  shell: /bin/bash -e {0}

@kjplunkett Did you solve this?

If so, do you remember how?

Yes I made a rookie mistake...didn't have a Dockerfile in my repo at this point so naturally this error arose:

unable to prepare context: unable to evaluate symlinks in Dockerfile path:

I didn't have a docker file in the project 🤦 - see #1 (comment)

(root directory name)
|-- buildspec.yml
`-- Dockerfile

Below sample Dockerfile

FROM golang:1.12-alpine AS build
#Install git
RUN apk add --no-cache git
#Get the hello world package from a GitHub repository
RUN go get github.com/golang/example/hello
WORKDIR /go/src/github.com/golang/example/hello

Build the project and send the output to /bin/HelloWorld

RUN go build -o /bin/HelloWorld

FROM golang:1.12-alpine
#Copy the build's output binary from the previous build container
COPY --from=build /bin/HelloWorld /bin/HelloWorld
ENTRYPOINT ["/bin/HelloWorld"]
