DOLFINx Dockerfile

Hello, I’m installing DOLFINx using Dockerfile. When running docker build . I receive, “failed to solve with frontend dockerfile.v0: failed to create LLB definition: dockerfile parse error line 15: unknown instruction: DOCKER”. Any ideas on this?

Please post your Dockerfile here, and in particular the name of your file, as some similar errors has been resolved by correct capitalization, as seen here: docker - Failed To Resolve With FrontEnd DockerFIle.v0 - Stack Overflow

name is Dockerfile
