Unable to build oracle rac docker image

[EricYinyifan]

I keep encountering the following problems when making images, and I can't find a solution at all.

There was an error building the image.

It looks like the error is here:

320.3 [FATAL] [INS-40937] The following hostnames are invalid:buildkitsandbox
320.3 CAUSE: The hostname or names listed are invalid.
320.3 ACTION: Ensure that you are not providing aliases, and that the hostnames you provide are valid.

What are the results from the DNS checks?

Whats the version of docker and whats image of Docker host machine? RAC on 19.3.0 is currently supported and tested with docker version 19.x from oracle's yum repo of Oracle Linux 7. All the host machine details are documented in README file -> https://github.com/oracle/docker-images/blob/main/OracleDatabase/RAC/OracleRealApplicationClusters/README.md Details are here https://blogs.oracle.com/virtualization/post/install-docker-on-oracle-linux-7 and this docker version is not having buildx enabled by default.

But from above error looks like you are trying to build on unsupported version of docker where buildx is enabled. Hence the issue. Generally, buildx is disabled via "export DOCKER_BUILDKIT=0" in any linux machine before doing the docker build but here on Oracle Linux 7 you don't need this, hence its not mentioned in instructions. Instructions clearly mentions prerequisites for same in "Section 4.1 : Prerequisites for Running Oracle RAC on Docker"

If you follow documented instructions and pre-requisites, this shall build fine. Let me know if this doesnt helps.

Here's my docker info，based on your suggestion, I'm going to try to close buildx before building the image, and I'll feed back the results here
