docker - 如何修改镜像名称?

Question

看到一个镜像的名称是空的,怎么给它添加名字呢?

Answer 1

docker tag imageid name:tag correct solution.
In csphere, the docker management platform, you can also add tags to images online

Answer 2

The empty image is the "cache" during pull. Just delete it directly with docker rmi IMAGE ID.

------update-----

It turns out that this image is being used by a certain container, and the poster wants to save it. Then the steps are as follows:

docker ps -a | grep 镜像 ID # Get the ID of this image to get the correct container ID

docker commit -a 'message aaaa' CONTAINER_ID NEW_IMAGE_NAME # Save the container as a new image.

Answer 3

docker tag IMAGEID new_repository newTAG Try this

Answer 4

<none>: There are two types of <none> one is benign and depends on other layers when building the image. This none image is normal.
One is build failure<There are various problems that cause the failure. Dockerfile file syntax error, file downloading is blocked when running, own cancellation action, etc.> This kind of none image can be cleared. After the successfully built image is pushed, you will not be able to see the benign none image after pulling.
