[@harshachowdary6875]

what is the difference between docker build and docker run?

[@salarahmad4385]

Build is to create image from Dockerfile and run is to create a container

[@ValaxyTechnologies]

Yes. thats true.

[@sureshkumar30111981]

If you, for one reason or the other, are still actively using CentOS 8, you might probably have encountered the following error when trying to update your system or simply install a package. “Error: Failed to download metadata for repo ‘appstream’: Cannot prepare internal mirrorlist: No URLs in mirrorlist” You may well be aware that CentOS Linux 8 died a premature death, it reached the End Of Life (EOL) on December 31st, 2021, thus it no longer receives development resources from the official CentOS project.
