Unknown instruction CMD["nextpy","init","&&","nextpy","run"]

[anirudh-hegde]

FROM python:3.8-alpine WORKDIR /app COPY Casper.py . COPY requirements.txt . RUN pip install -r requirements.txt CMD["nextpy","init","&&","nextpy","run"]

When I try to build, it shows the error: ERROR: failed to solve: dockerfile parse error on line 7: unknown instruction: CMD["nextpy","run"]

Somebody please reply

This shouldn't be a nextpy problem, from your description it should be a Dockerfile syntax mistake.. Change line 6 to CMD ["nextpy", "init", "&&", "nextpy", "run"] and try again.

Can you please explain how your syntax differs from my syntax

@anirudh-hegde CMD requires a space to distinguish that this is a keyword recognized by the Dockerfile. Just from the description looks like this
