我做了 docker 构建，然后 docker 拉取但失败了，为什么？

Question

我对构建自己的 Docker 图像还很陌生，所以我想了解我错过了哪一步。

docker build -t cirrus-bluecost-ssc-file-generator ./docker-container/

Use 'docker scan' to run Snyk tests against images to find vulnerabilities and learn how to fix them

它显然成功了，构建了一个图像并将其放在某个地方。

假设接近对面，试过

docker 拉 cirrus-bluecost-ssc-file-generator。得到

Using default tag: latest
Error response from daemon: pull access denied for cirrus-bluecost-ssc-file-generator, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

使用您尝试将映像推送到的容器注册表的路径标记您的映像：

docker tag cirrus-bluecost-ssc-file-generator <container-registry-path>/cirrus-bluecost-ssc-file-generator:latest

将镜像推送到容器注册表：

docker push <container-registry-path>/cirrus-bluecost-ssc-file-generator:latest

现在您可以使用以下命令拉取镜像：

docker pull <container-registry-path>/cirrus-bluecost-ssc-file-generator:latest

我做了 docker 构建，然后 docker 拉取但失败了，为什么？

I did a docker build, then docker pull but failed, why?
