Passing GitHub secrets in Actions step

      - name: Build domain service image
        uses: docker/build-push-action@v2
        with:
          push: true
          context: domain-service
          tags: |
            dizy/ambassador-test-domain-service:latest
            dizy/ambassador-test-domain-service:${{ github.sha }}
          secrets: |
            "github_username=${{ secrets.PERSONAL_GITHUB_USERNAME }}"
            "github_token=${{ secrets.PERSONAL_GITHUB_ACCESS_TOKEN }}"

Use secrets in Dockerfile

RUN --mount=type=secret,id=github_username --mount=type=secret,id=github_token git config --global url."https://$(cat /run/secrets/github_username):$(cat /run/secrets/github_token)@github.com".insteadOf "https://github.com"
