Go 如何在 Docker 容器中使用私有存储库进行身份验证

我有一个Git存储库，这是一个私有存储库，我需要使用它进行身份验证的能力，并能够在运行时在container build透视图中看到它.对于一些背景信息，我有一个GitHub工作流，它构建一个容器映像并将其发布到ghcr.io注册表.然而，因为我的包所依赖的存储库是私有的，所以它不能工作.现在它在本地运行，我已经考虑过改变我存储GitHub身份验证的方式，以便我可以访问它，但我想知道是否有人知道更好的方法让我访问私有存储库.

以下是GitHub操作发布到ghcr.io注册表:

name: Docker dataeng_github_metrics

# Run workflow on tags starting with v (eg. v2, v1.2.0)
on:
  push:
    branches: [ "master" ]
    paths:
      - ./data_pipelines/dataeng_github_metrics/*
  pull_request:
    branches: [ "master" ]

jobs:
  Deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Code
        uses: actions/checkout@v1
        
      - name: Login to GitHub Container Registry
        uses: docker/login-action@v1
        with:
          registry: ghcr.io
          username: ${{ github.repository_owner }}
          password: ${{ secrets.GHCR_REGISTRY_TOKEN }}

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v2

      - name: Build and Push Docker Image
        uses: docker/build-push-action@v3
        with:
          context: ./data_pipelines/dataeng_github_metrics/
          file: ./data_pipelines/dataeng_github_metrics/Dockerfile
          push: true # Will only build if this is not here
          tags: |
            ghcr.io/mirantis/dataeng_github_metrics:latest
          # TODO: I CANNOT USE DATAENG AS PUBLIC AND NEED TO CHANGE THE WAY GITCONFIG IS USED IN THE DOCKERFILE FOR AUTHENTICATION
          secrets: |
            TOKEN=${{ secrets.AUTOMATION_PAT}}

以下是前Dockerfile名:

###############
# CACHE IMAGE #
###############
ARG GO_IMAGE=golang:1.17.3-alpine3.14
ARG BASE_IMAGE=alpine:3.14.2

FROM ${GO_IMAGE} AS cache
# Add the keys
ARG GITHUB_ID
ENV GITHUB_ID=$GITHUB_ID
ARG GITHUB_TOKEN
ENV GITHUB_TOKEN=$GITHUB_TOKEN

# Install Git
RUN apk add git

# TODO: ENCRYPT THE GITHUB_ID AND GITHUB_TOKEN
# Make Git Configuration
RUN git config \
    --global \
    url."https://${GITHUB_ID}:${GITHUB_TOKEN}@github.com/".insteadOf \
    "https://github.com/"

WORKDIR /src
COPY go.mod go.sum /src/
RUN go mod download

##############
# BASE IMAGE #
##############
FROM cache AS dataeng_github_metrics
COPY . /bin
WORKDIR /bin

# Setup Git Terminal Prompt & Go Build
RUN go build .

###############
# FINAL IMAGE #
###############
FROM ${BASE_IMAGE}
COPY --from=dataeng_github_metrics /bin/dataeng_github_metrics bin/
ENTRYPOINT [ "bin/dataeng_github_metrics" ]

我认为让我感到困惑的重要部分是这一点，但我想知道是否有更好的方法来实现它:

# Make Git Configuration
RUN git config \
    --global \
    url."https://${GITHUB_ID}:${GITHUB_TOKEN}@github.com/".insteadOf \
    "https://github.com/"

如何访问私有存储库并避免工作流中的以下错误:

#14 9.438   remote: Repository not found.
#14 9.438   fatal: Authentication failed for 'https://github.com/Mirantis/dataeng/'
