Unable to install docker-credential-ecr-login using watchtower dockerfile

[Ostico]

Describe the bug

It's happening again #1719 ; I tried different Go versions up to the version 23.

The Dockerfile fail to build.

Steps to reproduce

Just follow the documentation at: https://containrrr.dev/watchtower/private-registries/#example

This is my Dockerfile:

FROM golang:1.18

ENV GO111MODULE off
ENV CGO_ENABLED 0
ENV REPO github.com/awslabs/amazon-ecr-credential-helper/ecr-login/cli/docker-credential-ecr-login

RUN go get -u $REPO

RUN rm /go/bin/docker-credential-ecr-login

RUN go build \
 -o /go/bin/docker-credential-ecr-login \
 /go/src/$REPO

WORKDIR /go/bin/

Expected behavior

Should compile the go binary executable.

Hey @Ostico 👋,

i have got it working with the following with the following:

Dockerfile:

RUN apk add --no-cache git && \
    git clone https://github.com/awslabs/amazon-ecr-credential-helper.git /amazon-ecr-credential-helper

WORKDIR /amazon-ecr-credential-helper/ecr-login/cli/docker-credential-ecr-login

RUN go build -o /go/bin/docker-credential-ecr-login

WORKDIR /go/bin

docker-compose.yml:

Please let me now, if it also works for you 👌

@Crinchy yes, building from source code worked for me too. Thank you!
